The OFAC SDN List has seen dramatic growth over the last decade, expanding from approximately 15,200 entries in late 2015 to over 17,000 by mid-2026. This growth accelerated sharply between 2017 (880 annual additions) and 2024 (over 3,000–4,000 additions). This expansion was driven largely by “maximum pressure” campaigns against Iran and extensive sectoral sanctions targeting Russia following the 2022 invasion of Ukraine. In early 2026, the second Trump administration maintained a high tempo of activity but shifted its rhetorical focus toward “sanctions modernization.” Notable recent benchmarks include April 2026, which saw 172 additions, and historical single-day records, such as February 2024, when over 500 entries were added at once. The current window (June-August) historically shows mixed activity; for example, June/July 2025 saw relatively small batches (4 to 28 entries), while April 2026 saw batches as large as 39 entries. This illustrates the irregular, event-driven nature of the list.
My prediction is derived from a synthesis of recent monthly run rates, historical annual benchmarks, and the specific policy environment of the second Trump administration as of mid-2026.
The primary baseline for this forecast is the recorded activity in April 2026, where OFAC added 172 individuals and entities to the SDN List. Extrapolating this monthly rate to the 64-day forecast window (approximately 2.1 months) suggests a baseline of roughly 360 additions. However, I have adjusted this baseline slightly downward to a most likely value of 277.50 to account for the “judicious use” and “sanctions modernization” policy explicitly articulated by Treasury Secretary Scott Bessent and Assistant Secretary Jonathan Burke in early 2026. This policy signals a shift away from measuring success by the quantity of names added and toward the strategic impact of those names. Consequently, while the sanctions apparatus remains highly active, the frequency of massive, multi-hundred-entry batches appears to be more controlled than during the 2024 peak, which saw annual additions reach between 3,000 and 4,000 (a pro-rata rate of 525–700 for a 64-day period).
I have weighted the forecast toward a range of 127.5 to 397.5 (the 50% HDI) to reflect the “batch-driven” nature of OFAC actions. The SDN list does not grow linearly; it grows in bursts. In April 2026, for instance, nearly half of the month’s additions occurred in just two days (April 24 and 28). My model accounts for the high probability that two to four such medium-sized batches (ranging from 20 to 50 entries each) will occur during the 9-week window, supplemented by smaller, routine designations.
I also considered a significant right-tail risk. Historical data shows that OFAC is capable of adding over 500 entries in a single day, as seen in February 2024. The ongoing “Economic Fury” campaign against Iran and the “maximum pressure” stance on Mexican and Brazilian criminal organizations provide ready-made vehicles for such large-scale actions. If a major procurement network involving dozens of front companies in the UAE, Hong Kong, and Singapore is dismantled simultaneously, the count could easily exceed 500. However, without a known specific trigger or anniversary (like the start of a war) falling within the June-August window, these massive events remain a lower-probability scenario compared to the moderated baseline.
The final estimate of 277.50 balances the high administrative activity seen in 2024-2025 with the deliberate policy deceleration observed in the first half of 2026. The 50% HDI reflects the inherent uncertainty of “lumpy” data where the absence or presence of just one major enforcement action can shift the total by 50 or 100 entries.
The question asks how many new OFAC SDN entries will be added in the 64-day window 2026-06-09 through 2026-08-11 (counting only newly added SDN records). Forecasters agree the window is “lumpy” rather than a smooth daily process and that a baseline of small-to-medium actions (Iran oil/shipping/financial facilitators, terrorism, counternarcotics, cyber/human-rights) makes a typical window in the few-hundreds of additions — agents’ rough prior gives median ≈260 with other analysts placing the median/central case in the low‑ to mid‑300s. All teams flag a meaningful upper tail driven by a possible G7-coordinated Russia package around the Jun 15–17 summit (historical analogues show such tranches can add hundreds), but note current Russia signals are mixed so this is plausible rather than pre-announced. Counternarcotics and episodic cartel packages can add double-digit to multi‑dozen bumps and are treated as secondary but nontrivial contributors. Forecasters place meaningful mass in the 250–600 range, some mass in 600–1,200 if Iran plus a Russia tranche materialize, and only a small open probability for >1,500 (which would require multiple very large packages). Practical guidance: track OFAC Recent Actions and list-change files live, decompose counts by program, and update quickly after Jun 15–17 to shrink or expand the Russia-driven upper tail.
Forecast: Probability distribution:
We are forecasting the number of new SDN entries added by OFAC during 2026-06-09 through 2026-08-11 (UTC, inclusive; about 64 days). Additions come in irregular “packages,” so variance is driven more by (a) how many action days fall in the window and (b) whether one or two unusually large packages (Iran shadow-fleet style, major counternarcotics/cyber/Russia-evasion sweeps) land inside the window.
Across the analyst team, the most evidence-backed anchor is the claimed 2026 year-to-date pace (roughly ~600 SDN additions by early June, i.e., on the order of ~120/month and ~4/day on average), which implies a central expectation around ~250–270 additions over ~64 days. A second anchor (2025 total ~1,300) implies a somewhat lower monthly average (~110/month), yielding ~220–240 for a similar-length window. These are close enough that the median should sit near ~250.
I therefore center the distribution around ~255 additions (median), with a moderately wide lower tail (recognizing a quieter-than-usual period is possible) and a heavy right tail (recognizing one or more large, clustered designation packages can add hundreds of entries). I keep essentially all mass well below 1,500 because exceeding that in ~2 months would require an extraordinary, historically unusual surge in designations.
An amateur forecast often (1) linearly extrapolates from a single recent update size (too low) or from an extreme year like 2024 (too high), and (2) underestimates the heavy-tailed, package-driven nature of OFAC additions. This forecast explicitly blends (a) recent-year run-rate anchors cited by multiple analysts with (b) a right-skewed uncertainty structure reflecting batch risk, producing a better-calibrated median and wider, more realistic upper tail. Confidence in improvement: moderate, because the main residual uncertainty is whether a major sanctions package happens to fall within this specific 64-day window.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the reasoning is broadly consistent:
Primary anchor: recent 2026 pace.
Each estimate starts from OFAC’s year-to-date activity, roughly 614 SDN additions over about 150 days, implying a baseline of about 4 additions per day. Applied to the 64-day window from June 9 to August 11, this yields a rough expectation in the mid-200s.
Central estimate adjusted slightly downward.
The median is generally set a bit below the raw extrapolation, reflecting:
OFAC activity is treated as batchy and uneven.
A major shared assumption is that SDN designations are not smooth or linear. Most periods may see modest additions, but a single action can add dozens or even hundreds of names at once.
Right-skewed uncertainty dominates.
The distributions are intentionally heavily right-skewed:
Consensus and differences.
The forecasts cluster around a central estimate in the low-to-mid 200s:
The main disagreement is not about the direction of the forecast, but about how conservative to be in the center and how wide the tail should be. Some forecasters allow for extremely large outcomes in rare cases, while others keep the upper tail somewhat tighter.
Bottom line: the shared logic is that the window should likely see around 230–270 new SDN entries, driven by extrapolation from recent OFAC cadence, but with substantial uncertainty because OFAC often acts in large, irregular batches.
— Iteration 2 — Across the forecasts, the dominant approach is to extrapolate from 2026 year-to-date SDN listing activity. Using the reported pace of roughly 614 designations over 148 days (about 4.15 per day), the models project a mid-200s outcome over the 64-day window from June 9 to August 11, 2026. The central estimates cluster tightly around this baseline, indicating strong agreement that the most likely result is roughly 250–275 entries.
A second shared theme is that the distribution is treated as highly right-skewed. The models assume OFAC actions often come in batches, so while the average pace implies a moderate total, there is meaningful upside risk from a single large sanctions package tied to events involving Russia, Iran, cartels, or other geopolitical shocks. This is why the forecasts include wide upper tails and acknowledge the possibility of very large spikes.
There is some modest disagreement on the point estimate: one forecast nudges the total slightly upward on the assumption that sanctions activity remains elevated, while others pull it slightly downward to reflect a possible summer slowdown or quieter administrative period. Even so, the overall consensus is clear: the expected number of additions is in the mid-200s, with uncertainty driven less by normal day-to-day variation than by the chance of large, episodic designations.
— Iteration 3 — Across the forecasts, the dominant view is that the SDN List will see a few hundred new entries during the 64-day window, with a central estimate roughly in the 225–310 range and an expected mean near 275–300.
Summary of Rationale Arguments
To forecast the volume of additions to the OFAC Specially Designated Nationals (SDN) List between June 9 and August 11, 2026, the rationales weigh recent historical baselines and competing policy directives against a dense calendar of geopolitical catalysts.
Recent Pacing and Enforcement Momentum The forecasters broadly agree on the baseline trend: following historic, Russia-driven highs in 2024, the raw volume of sanctions dropped in 2025. However, pacing has markedly accelerated in the spring of 2026. This recent surge is primarily attributed to the current administration’s “Economic Fury” campaign, which heavily targets Iran’s “shadow fleet” of maritime vessels, Chinese secondary enablers (such as “teapot” refineries), and transnational cartel and cryptocurrency networks.
Upward Pressures: Summits, Anniversaries, and “Mega-Batches” The rationales highlight that OFAC designations do not occur linearly, but rather in massive, event-driven “mega-batches.” The 64-day summer window is uniquely packed with established action-forcing events likely to trigger significant surges:
Downward Pressures: Policy Shifts and Diplomatic Risks Conversely, several structural headwinds could suppress the total volume of new entries:
In conclusion, the rationales balance the downward pressure of the Treasury’s “impact over volume” modernization efforts against the upward pressure of an escalating enforcement campaign and a summer schedule packed with highly reliable geopolitical forcing events.

The research summarizes OFAC/SDN activity through early June 2026 and projects possible addition counts for the 64-day period June 9–August 11, 2026. It notes a May 28, 2026 OFAC removal of 76 obsolete SDN entries as part of a sanctions-modernization effort, an SDN list size of over 17,000 names, and recent major 2026 designations (e.g., Iran’s Hormuz Control Administration; Brazilian criminal factions PCC and CV). Early-2026 activity (first 47 monitoring days) showed 869 total actions comprising 614 new designations and 255 removals (≈13.1 additions/day or ≈390/month). Historical baselines are presented: 3,135 additions in 2024 (~261/month), 1,322 in 2025 (~110/month), and ~880 in 2017. Using these rates, the research produces three point estimates for the 64-day window: 230 additions (2025 annual rate), 550 additions (2024 rate), and 838 additions (early-2026 pace), and identifies a “most likely” range of roughly 240–520 additions while acknowledging a wider plausible range of about 230–840 due to uncertainty.
The report highlights drivers and structural factors that affect addition counts: priority target areas (Iran, China, transnational crime, drug cartels; Russia activity reduced in 2025), the batch/irregular nature of OFAC updates (single actions can add from a few to 100+ entities), geopolitical events (notably U.S.–Iran tensions), and the sanctions-modernization policy that may reduce low-value additions while preserving high-impact designations. It also notes no active prediction-market markets were found for this specific question. Key uncertainty factors listed include whether early-2026 high pace is sustainable, the effect of modernization, potential major designation actions, and the administration’s stated preference for more selective sanctions.

Recent Developments:
2026 Activity Through June 3: In the first 47 days of monitoring (approximately May-early June 2026), OFAC took 869 total actions, including 614 new designations and 255 removals [15]. This translates to approximately 13 additions per day or ~390 per month.

Historical 2-Month Comparable Periods:
Key Uncertainty Factors:
Reference Class: The 2025 full-year total of 1,322 additions under similar Trump administration policy provides the most relevant baseline, suggesting 220-240 additions for a 64-day period. However, early 2026 activity suggests higher pace, potentially 400-600 additions if current geopolitical tensions (particularly Iran) drive continued designation actions.
The wide range (230-840) reflects genuine uncertainty between a return to 2025’s restrained pace versus continuation of early 2026’s elevated activity levels.
(a) Time left. Today is June 3, 2026. The forecast window is June 9 through August 11, 2026 inclusive, a 64-day counting period starting in about 6 days. The outcome should be knowable at the end of August 11, 2026 UTC, i.e. about 69 days from today, conditioning on the question not being annulled.
(b) Outside view. The closest base rate is the second Trump administration’s 2025 SDN designation pace: 1,322 persons added to the SDN List in 2025, implying about 232 additions over 64 days. Broader recent annual rates give a wider reference class: 3,135 persons in 2024 implies about 550 over 64 days, while Treasury says annual new listings rose from 880 in 2017 to over 3,000 in 2024, implying roughly 154 to 526+ over 64 days depending on the year chosen. (cnas.org)
(c) Inside view. The 2026-to-date pace is elevated but not as high as the research note’s “13 per day” would imply on a calendar-day basis: the cited 614 designations and 255 removals across 47 action days are spread over roughly five months, so the calendar-day continuation is closer to 255–260 entries for a 64-day window. The current action mix is still add-heavy: recent OFAC actions include Iran “maximum pressure” / “Economic Fury” actions, such as the June 2 Nobitex-related update and the May 28 Iran oil/shadow-fleet update, adding batches of individuals, entities, and vessels. (fluet.law)
(d) Outcome if nothing changed. If OFAC made no SDN additions during June 9–August 11, the outcome would be 0 OFAC entries. That is very unlikely because OFAC has frequent Recent Actions updates, but it is the literal no-change case.
(e) Outcome if the current trend continued. Using 614 additions over the elapsed 2026 calendar year to date gives roughly 4.0 additions per calendar day, or about 255–260 OFAC entries over the 64-day period. I treat this as the main anchor, not the action-day-only rate.
(f) Expectations of experts and markets. I found no liquid prediction market specifically for this administrative count. The best expert-adjacent signal is CNAS’s 2025 sanctions review: the current administration’s SDN additions were much lower than 2024 but concentrated in Iran-related sanctions evasion, China-linked evasion, transnational crime, and drug/cartel networks. Treasury’s own modernization language points toward impact-focused sanctions rather than maximizing list volume, which slightly lowers the forecast versus a simple continuation of 2024-style activity. (cnas.org)
(g) Low-outcome scenario. A low outcome could happen if U.S.–Iran tensions cool, OFAC prioritizes modernization/removals and compliance cleanup, and the period contains only small counterterrorism or counter-narcotics designations. That could plausibly leave the count below 100 OFAC entries.
(h) High-outcome scenario. A high outcome could result from a major Iran escalation, a large secondary-sanctions action against shipping/energy networks, a breakdown in Russia diplomacy, or a broad cartel/transnational-crime package. One or two very large network actions could push the count above 700, and a multi-program sanctions surge could exceed 1,000.
Rationale. I anchor on the 2025 Trump-administration base rate of about 230 additions for a 64-day period because it is the closest political and policy reference class. I then move modestly upward because 2026 activity remains brisk, the current OFAC action list is Iran-heavy, and the administration is still publicly pursuing maximum pressure against Iran. I do not move toward the research note’s 800+ continuation figure because that appears to apply an action-day average to all calendar days; OFAC actions are lumpy and many days have no additions. I also do not move all the way down to the older first-Trump/2017 pace because the current sanctions toolkit is larger and Iran/cartel/network designations remain active. My median is therefore around 265 OFAC entries, with a heavy right tail for large batch actions.

Conditioning on the question not being annulled.
(a) Time left. The counting window starts in 6 days, on June 9, 2026, and runs through August 11, 2026 UTC inclusive, a 64-day window. The outcome should be knowable in about 69 days, once OFAC’s August 11 list changes are published.
(b) Outside view. The best reference class is recent annual SDN additions under the same administration. CNAS reports that the Trump administration added 1,322 persons to the SDN List in 2025, versus 3,135 in 2024 under Biden; that implies about 232 additions over 64 days using 2025, or about 548 using 2024. (cnas.org) A secondary reference class is 2026 year-to-date: the research source reports 614 designations and 255 removals across 47 action days so far in 2026, which annualized over calendar days is roughly 255-260 additions for a 64-day window, not 838. (fluet.law)
(c) Inside view. The strongest upward factor is that OFAC’s recent actions page shows repeated sanctions-list updates in late May and June, including Iran, counter-terrorism, DRC, and ICC-related actions, so the pipeline is clearly active right before the forecast window. (ofac.treasury.gov) The strongest downward factor is Treasury’s “sanctions modernization” framing and the May 28 removal of 76 obsolete targets, which suggests more selectivity and less volume-for-volume’s-sake. (fluet.law) I also correct the research assistant’s main quantitative overstatement: “614 in 47 action days” should not be treated as 13 additions per calendar day, because those were only action days.
(d) Outcome if nothing changed. If OFAC simply made no new SDN additions during June 9-August 11, the outcome would be 0 OFAC entries. That is possible but very unlikely over 64 days.
(e) Outcome if the current trend continued. Using 2026 year-to-date on a calendar-day basis, I get roughly 255-260 OFAC entries. Allowing for “entries” rather than normalized “persons,” and for continued Iran/cartel activity, a status-quo median is closer to 280-300 OFAC entries.
(f) Expectations of experts and markets. I find no useful liquid prediction-market signal for this administrative metric. Expert commentary points to continued sanctions use, especially around Iran, China-linked evasion, drug trafficking, and transnational crime, but with a more selective approach and restraint where sanctions could interfere with dealmaking. (cnas.org)
(g) Low-outcome unexpected scenario. A diplomatic de-escalation with Iran or China, combined with OFAC prioritizing delistings/cleanup and having pulled forward designations into late May and early June, could leave the period with only a few small actions, perhaps under 75 entries.
(h) High-outcome unexpected scenario. A major Iran escalation, a large shadow-fleet/oil-evasion package, renewed Russia sanctions after failed negotiations, or a broad cartel/FTO crackdown could generate multiple 100+ entry batches and push the total above 900 entries.
Rationale. I anchor on the 2025 same-administration base rate of about 230 additions per 64 days, then update upward to reflect the active 2026 tempo and the concentration of recent Iran, terrorism, and narcotics-related actions. I do not update all the way to the research assistant’s 800+ figure because that extrapolates action-day intensity as if every calendar day were an OFAC action day. My median forecast is therefore 290 OFAC entries, with a mean somewhat higher because the process is lumpy and right-tailed: one major geopolitical sanctions package can add hundreds of entries, while the downside is bounded near zero.

(a) Time left: The counting window starts on June 9, 2026 and ends on August 11, 2026, inclusive. As of June 3, 2026, that is 6 days until the window starts and about 69 days until the final resolution date.
(b) Outside view: The best reference class is recent annual SDN additions under the current administration. CNAS reports 1,322 SDN additions by the Trump administration in 2025, versus 3,135 in 2024 and 2,502 in 2023 under Biden-era policy. Scaled to 64 days, those imply roughly 232, 550, and 439 entries, respectively. Treasury also notes that annual new listings rose from 880 in 2017 to over 3,000 in 2024, before the current “modernization” emphasis. (cnas.org)
(c) Inside view: The biggest correction to the research assistant’s report is that “614 designations across 47 action days” should not be extrapolated as 13 additions per calendar day; OFAC has many non-action days. Spread over roughly January 1–June 3, 2026, 614 additions is closer to 4 additions per calendar day, implying about 255–265 entries over 64 days. That lines up closely with the 2025 Trump-administration base rate rather than implying an 800-plus entry outcome. Still, Iran-related “maximum pressure,” cartel/TCO designations, and occasional large network actions push the tail upward. (fluet.law)
(d) Outcome if nothing changed: If OFAC made no SDN additions during June 9–August 11, the outcome would be 0 OFAC entries.
(e) Outcome if the current trend continued: Using the more appropriate calendar-day version of the 2026 trend gives about 260 OFAC entries during the 64-day window.
(f) Expectations of experts and markets: I found no liquid prediction-market signal for this administrative count. Expert/analyst signals are indirect: CNAS shows the current administration was much less volume-heavy than 2024, while Treasury’s modernization statements explicitly say success should be measured by “effect, impact, and national security benefit,” not just list volume. (cnas.org)
(g) Unexpected low scenario: A diplomatic pause with Iran, Venezuela, or Russia; staff/legal review delays; or a policy push to emphasize removals and fewer “bulk” network designations could produce a low outcome, say under 75 entries.
(h) Unexpected high scenario: A major Iran escalation, a large shadow-fleet/oil-smuggling package, a broad cartel/TCO action, or a Russia/China sanctions-evasion package could add several hundred entries in one or two batches, producing 700+ entries despite the normal base rate.
Rationale: I anchor on the 2025 Trump-administration base rate because it is the closest policy regime: 1,322 additions/year, or about 232 entries for 64 days. The early-2026 data does not justify the research report’s 800-plus “current trend” extrapolation because the 614 count is over action days, not all calendar days. Re-expressed correctly, early 2026 points to roughly 260 entries, very close to the 2025 base. I move the median modestly upward from 232 to 270 because Iran-related actions appear active, recent OFAC pages show continued designations, and sanctions actions are lumpy with right-tail risk. But I keep the 80th–95th percentiles far below 1,500 because matching the 2024 Biden-era pace would already be around 550 entries for this window, and the current Treasury posture is explicitly less volume-maximizing.

The resolution criteria are precisely defined: only newly added SDN entries within the exact date window count, with explicit exclusions for removals, delistings, and re-designations. The criteria name a specific source (OFAC’s Recent Actions / Sanctions List Updates) and a specific measurement date, leaving little room for charitable interpretation.

Evidence confidence: medium
high evidence]OFAC maintains a monthly pace near its 2026 YTD average of ~122/month across the ~2.1-month window. No single large coordinated enforcement action (400+ entries) occurs. Ongoing focus on Iran, Mexico cartel, and counterterrorism programs continues at recent rates. The 2026 monthly figures for February–May 2026 (82, 34, 172, ~164) bracket this range.
A major geopolitical escalation or large coordinated enforcement action could push totals well above 300. Conversely, a policy shift toward further ‘sanctions modernization’ or diplomatic engagement could suppress new designations below 200.
medium evidence]OFAC issues one or more large coordinated enforcement actions (e.g., against a drug trafficking network, Iran energy sector, or Russia-linked entities) that each designate 100–400 entities in a single action. October 2025 showed ~371 entries in a single month. The 2026 monthly figures already show a 5x range (34 to 172), and a single outlier month could push totals well above the base-rate projection.
The 2025 and 2026 YTD data show the Trump administration designating at a lower rate than Biden. No evidence of a scheduled large enforcement action during this window. The June–August window may see reduced activity during summer months.
medium evidence]OFAC continues or expands its ‘sanctions modernization’ initiative, suppressing new designations. The policy environment shifts toward diplomatic engagement (e.g., Iran nuclear negotiations, cease-fire agreements) reducing designation appetite. March 2026 demonstrated a very low month (34 additions) is possible even under the current administration.
The 2026 YTD average (~122/month) and recent months (April 172, May ~164) are inconsistent with a sustained 2-month suppression to this level. No current evidence of policy changes that would drastically reduce designations over the full window.
low evidence]Escalating geopolitical pressure (e.g., Russia/Ukraine, Iran nuclear crisis, major drug trafficking crackdown) triggers multiple large enforcement actions. Historical Biden-era precedent shows months exceeding 300–500 additions are possible when multiple programs are activated simultaneously.
2025 and 2026 YTD data consistently show Trump administration designating at ~110–122/month, well below Biden-era highs. No evidence of escalation or policy shift toward dramatically higher designation rates. Achieving 750+ in ~2 months would require a ~5x acceleration from current pace.
inside_view_v1)Inside View Causal Analysis
Current state → causal mechanism → outcome:
The 2026 YTD monthly average is ~122 additions/month (614 designations through ~June 1 per Fluet Law). The window is ~2.1 months (June 9–August 11). Base-rate projection: 122 × 2.1 ≈ 256 additions.
Scenario weighting by evidence strength:
Moderate pace ~200–300 additions (
relative_evidence_strength: high): This scenario has the strongest support. Feb 2026 = 82, March = 34, April = 172, May ≈ 164, YTD average ~122/month. The full-year 2025 Trump pace was ~110/month. The causal chain: Trump administration continues cartel/Iran/counterterrorism designations at current pace → 2.1 months × ~120/month → ~250 total. The bin covering 188–375 captures this scenario’s central mass.Low-count ~50–150 additions (
relative_evidence_strength: medium): March 2026 showed only 34 additions (highly unusual). Sanctions modernization is increasing removals. But April and May rebounded strongly (172, ~164), suggesting March was idiosyncratic. For the full 2.1-month window to land below 188, BOTH months would need to be very low. Possible but against trend. This gives 0–188 (bin_1) modest probability.High-count ~400–750 additions (
relative_evidence_strength: medium): October 2025 spike of ~371 in one month is the key evidence. One large batch action could push 2.1 months above 375. Medium evidence strength means meaningful but not dominant weight. Bin_3 (375–563) gets meaningful probability; 563–750 (bin_4) gets smaller share.Very high count ~750–1,500 (
relative_evidence_strength: low): Requires 5x acceleration from current pace. Biden-era comparisons don’t directly apply given different policy priorities. Very small tail probability.Distribution shape:
- Central mass in 188–375 (bin_2): This captures the base-rate projection of ~256 additions and the moderate scenario. ~45% probability.
- Bin_1 (0–188): Low-count scenarios. March-like months combined, or prolonged suppression. ~20% probability.
- Bin_3 (375–563): One large batch action pushes above 375. Medium evidence supports this. ~18% probability.
- Bin_4 (563–750): Two large batch actions or one very large one. ~8% probability.
- Bin_5 (750–938): ~4% — requires dramatic acceleration.
- Bins 6–9: Very small tail. ~5% combined.
- Bin_0: Impossible (0 SDN additions over 63 days would mean OFAC completely ceases operations). ~0%.
The confidence_in_evidence is “medium,” which warrants a wider-than-usual distribution. I widen accordingly while keeping central mass in bin_2.
outside_view_v1)Reference class: monthly OFAC SDN additions, aggregated over a ~2.1 month window (June 9–Aug 11, 2026). Base rate: 2026 YTD data imply ~122 additions/month (614 through ~June 1 → Fluet Law), so a simple outside-view multiply gives ~122 × 2.1 ≈ 256 entries for the window (falls in bin_2: 188–375). Adjustment: +/− uncertainty and heavy-tail risk from batch actions. The brief documents large month-to-month volatility (April 2026 = 172 additions, March 2026 = 34 additions — Hughes Hubbard), and historical single‑month spikes (Oct 2025 ≈ 371 entries — Solytics). It also confirms that an “entry” = one primary person/entity (OFAC FAQ 1031), so counts map cleanly to bins. Confidence in evidence = medium, so I keep the outside‑view anchor but widen tails to reflect plausible large coordinated actions and occasional suppressed months. Final distribution and why: • 188–375 (bin_2): 65% — centered on the base-rate anchor (~256) and supported by the brief’s high‑evidence scenario (“Moderate pace” labeled high evidence; see Fluet Law 614 YTD and April/May figures). • 0–188 (bin_1): 12% — captures credible downside (March‑style suppression; OFAC’s sanctions‑modernization delistings and possible diplomatic pauses; medium evidence). • 375–563 (bin_3): 12% and 563–750 (bin_4): 6% — together 18% represent the medium‑strength tail for one or more large batch designation actions (October 2025 demonstrates such spikes). The brief tags this scenario medium evidence, so nontrivial but not dominant mass goes here. • bins 5–9 (>=750): 5% total (split across bin_5 3%, bin_6 1%, bin_7 0.5%, bin_8 0.3%, bin_9 0.2%) — a small low‑confidence tail for multiple simultaneous very large actions (brief flags this as low evidence). • Below 0 (bin_0): 0%. This allocation follows the outside‑view anchoring (base ≈256) while obeying the brief’s scenario weights: the “moderate pace” (high evidence) carries the bulk of probability, medium‑evidence high/low scenarios get the mid tails, and low‑evidence extreme outcomes receive a small residual. I read the resolution strictly (use OFAC’s published SDN additions, count primary entries only, UTC‑inclusive dates), per the interpretation brief; this informed the mapping of scenarios to bins and prevents counting aliases or amendments as new entries (OFAC FAQ 1031 / data schema).
contrarian_v2)Adversarial reading
The bulk of the evidence (2026 YTD designations of 614 through ~June 1 implying ~122/month average, plus the February–May sequence of 82/34/172/~164) pulls the implicit consensus toward a moderate outcome centered near 256 additions for the ~2.1-month window, landing squarely in 188-375 (bin_2).
Counter-evidence found (or absence)
Searched for counter-evidence; the high month-to-month variance already visible in 2026 (34 vs. 172) plus the October 2025 single-month spike of ~371 (source 3) and the ongoing sanctions-modernization delisting effort (source 10) provide substantive counter-evidence that the moderate consensus could be displaced either downward or upward by batch actions or policy shifts.
Distribution implications
The high-evidence moderate scenario therefore receives the largest single allocation (bin_2 at 0.50), but the medium-strength low and high-batch scenarios still pull meaningful mass into 0.22 (bin_1) and 0.18 (bin_3) respectively; the low-evidence very-high scenario receives only thin tails beyond bin_4. This shape deliberately widens the distribution relative to a naive consensus point estimate while still centering the bulk on the high-evidence moderate bin.
Strategy: logit_mean • Drafts: 3/3
anchoring_v1The draft’s p50 falls squarely in 188–375 (bin_2), centered near the ~256 base-rate projection (122/month × 2.1 months). This anchor is reasonable but may be slightly optimistic relative to the modal expectation. The brief notes that the 2026 YTD average of ~122/month is itself derived from months with high variance (34, 82, 164, 172), and the 122 figure includes a computation gap for January 2026 that is unverified. More importantly, the draft places 54% of probability mass in bin_2 alone, which is too narrow given that the high-evidence “moderate” scenario spans 188–375 — the full width of that bin — not a tight point. The base-rate 256 is the mean of an irregular batch process with acknowledged outlier risk; the true modal bin should carry somewhat less mass while adjacent bins (especially bin_1 and bin_3) absorb more. The draft’s ~17.7% on 0–188 (bin_1) seems appropriate given that two low months in a row (like March 2026’s 34) could produce a sub-188 total, but the 54% on bin_2 creates an anchoring artifact that over-concentrates on the mean rather than reflecting genuine distributional uncertainty from a batch-action process.
ceiling_v1The key structural constraint here is the bin architecture relative to the empirical ceiling implied by the base-rate data. The brief establishes a 2026 YTD monthly average of ~122 additions/month and a ~2.1-month window, yielding a base-rate projection of ~256 additions — well within 188–375 (bin_2). The observed monthly range in 2026 is 34–172, meaning even sustained above-average months (e.g., two months at 172 each) produces only ~344 — still within bin_2. The structural ceiling for “normal operations” is therefore approximately bin_2’s upper boundary (375). To escape into 375–563 (bin_3) or beyond requires at least one major batch enforcement action; to reach bin_4+ (563+) requires either multiple such actions or an unprecedented policy shift. The brief’s evidence for the high-tail scenario is labeled “medium” and “low” strength respectively, yet the draft allocates ~7% to bins 4+ (563–750 and above). The October 2025 spike of ~371 (the single most extreme data point cited) would itself only fall in the lower portion of bin_3, not bin_4+. This implies the draft has slightly over-weighted the right tail beyond bin_3, and under-weighted the structural concentration in bin_2 given the strong anchoring of the base rate within it. The forecast should shift mass from bins 5–9 back toward bin_2 and modestly bin_3.
math_v1The distribution’s bin labels do not match the schema’s EXACT required bin_ids. The draft uses string labels like “0-188” and “Above 1500”, but the resolution criteria demand numeric bin_id keys: bin_0, bin_1, …, bin_9. This is a critical schema violation. Additionally, the probabilities sum to approximately 1.00 (confirmed: 0.177 + 0.540 + 0.159 + 0.070 + 0.029 + 0.013 + 0.004 + 0.003 + 0.003 + 0.001 ≈ 1.00), which is correct, but the mapping between the draft’s string keys and the numeric bin indices must be corrected.
Reviews consumed: 3
The anchoring reviewer flagged that the draft over-concentrates 54% in bin_2 and slightly under-weights the right tail (one batch action could push past 375); the ceiling reviewer pushed the opposite direction, arguing the structural ceiling caps plausible outcomes around 375–450 and that bins 5–9 are over-weighted. These two dissenting directions partially cancel: I kept bin_2 close to the draft’s ~54% (modestly higher per ceiling reviewer’s structural argument) and shifted a small amount of mass from far-right tail bins (5–9) into per ceiling reviewer’s point that even the October 2025 spike of 371 would only land in lower bin_3, not bin_4+ (bin_3). I rejected the anchoring reviewer’s call to widen bin_3/bin_4 aggressively because the ceiling reviewer’s structural ceiling argument (no Trump-era month has exceeded 172; 563+ requires >268/month sustained) is empirically stronger. The math reviewer confirmed the sum=1 and the schema mapping; I am using exact bin_id keys. Action is partial_shift: minor mass moved from bins 5–9 into bin_2/bin_3 to better reflect the structural ceiling.
[anchoring] Reduce bin_2 concentration below 50% and widen bin_3/bin_4 to ~20%/~9% to reflect batch-action fat tails.
[anchoring] Use 2025 full-year Trump pace (~110/month → 231 projected) rather than 2026 YTD (~122/month → 256).

Why a HIGH outcome could occur:
Assumption 1: 2026 YTD pace (~4/day) continues through summer

Assumption 3: Batch clustering remains similar to recent patterns
The distribution centers around 250-280 entries based on the 2026 YTD pace of ~4.1/day. I’m applying:
The 90% confidence interval spans roughly 130-550 entries to account for high variance in batch sizes and unpredictable geopolitical triggers.

Sanctions additions occur in discrete, lumpy designation actions rather than at a steady rate.
The SDN entry-expanded counting convention treats aliases and name variants as separate entries, raising counts versus a compact actor count.
Early-June pace implies a multi-hundred-entry baseline across a 64-day June–August window.
Active Iran maritime and shadow-fleet targeting, plus ongoing counter-narcotics actions, sustain upward pressure on additions.
A single large designation package timed inside the window can add hundreds of entries and shift outcomes decisively.
Conversely, diplomatic pauses or the same package landing just outside the window materially lower the resolved total.
Primary unresolved uncertainty is timing: the day a major package is published can change the count by hundreds.
Secondary sensitivity is measurement convention: whether adjudication uses entry-expanded SDN-change entries or compact Recent Actions summaries alters totals significantly.
Forecast (median): 391 entries added to the OFAC SDN List between June 9 and August 11, 2026.
I treated this as a bursty-count forecast, not a smooth-rate forecast. OFAC designations arrive in uneven batches tied to specific sanctions actions, so I started from a broad annual base rate, then adjusted for the current sanctions environment and for the fact that the resolution window is only 64 days long.
A useful anchor is Treasury’s statement on May 28, 2026 that annual new listings rose from 880 in 2017 to over 3,000 in 2024. If 3,000 were spread evenly across a year, that would imply about 526.03 additions in a 64-day window. That is not a prediction by itself, but it is a strong baseline for the overall system-wide scale OFAC has recently been operating at. (home.treasury.gov)
The current policy environment still looks active rather than dormant. Treasury’s May 28, 2026 Iran oil press release says the action continues a “maximum economic pressure” campaign against Iran, and the April 24, 2026 Iran shadow-fleet press release says that in 2025 OFAC sanctioned more than 875 persons, vessels, and aircraft as part of that Iran campaign alone. If that campaign-specific figure were annualized, it would correspond to about 153.42 designations in a 64-day window even before adding designations from other programs such as counterterrorism, narcotics, cyber, or regional programs. That pushes me away from any low-end forecast centered near zero or near only a few dozen additions. (home.treasury.gov)
The flow immediately before the target window also shows both activity and lumpiness. OFAC’s June 2, 2026 recent action lists six individuals and four entities added to the SDN List, for 10 additions. The May 29, 2026 action lists nine individuals and five entities, for 14 additions. The May 21, 2026 action lists nine individuals. The May 27, 2026 action lists one new entity. And the May 28, 2026 Iran oil action includes one individual, a long list of entities, and multiple vessels. So the near-term pattern is clearly not “nothing happens,” but it is also not a stable day-by-day drip; it is a sequence of small, medium, and occasionally large batches. (ofac.treasury.gov)
I also discounted the straight-line 2024 baseline somewhat because not every OFAC recent action adds names: some notices are removals or updates only. The recent-actions index includes a May 28, 2026 removals notice, and June 30, 2025 was a Syria updates/removals notice rather than a new-additions burst. Treasury’s May 28, 2026 modernization announcement also removed 76 outdated SDN entries. Since the question counts additions only and removals do not offset them, those removals are evidence of volatility and composition changes, not evidence that the additions count should be mechanically reduced one-for-one. (ofac.treasury.gov)
Putting those pieces together, I think the most likely outcome is in the broad middle hundreds, with a center a bit below the simple 2024 straight-line baseline but with a fat right tail in case OFAC issues one or two very large Iran/shadow-fleet/cartel packages during the window. I therefore used a three-scenario mixture: a low scenario centered around 260, a base scenario centered around 500, and a high scenario centered around 800, with weights 25%, 50%, and 25% respectively. That yields a forecast mean in the low 500s and keeps meaningful probability on both a quieter window and an unusually large-batch window.
I’m using OFAC’s own publications as the source of truth. OFAC says current-year SDN changes are cumulatively available in the SDN changes PDF, and its archive page maintains yearly files of SDN list changes; the Recent Actions pages enumerate sanctions list updates in the way this question intends to count them. (ofac.treasury.gov)
The closest recent analogue is the June 9 through August 11, 2025 window. Across the OFAC Recent Actions pages covering that span, I count 22 sanctions-list-update pages, which implies a fairly high action cadence but still one driven by discrete packages rather than a smooth daily flow. The batch-size volatility is the key forecasting feature: on June 20, 2025 OFAC issued one action targeting 4 individuals, 12 entities, and 2 vessels, and a second same-day action designating 1 individual, 8 entities, and 1 vessel; on July 30, 2025 OFAC described its move as its largest Iran-related action since 2018, designating more than 50 individuals and entities and identifying more than 50 vessels. (ofac.treasury.gov)
Current 2026 tempo is clearly active. In the short run just before the forecast window, the four addition pages I checked from May 27, 2026 through June 2, 2026 add up to about 40 new SDN entries: 1 on May 27, 24 on May 28, 6 on May 29, and 9 on June 2. Those actions were heavily Iran-focused, spanning oil shipping, procurement, and crypto-finance, with some counterterrorism and DRC designations mixed in. (ofac.treasury.gov)
So my base case is higher than a quiet-period baseline, but below a simple extrapolation of the hottest recent weeks. I start from something like 14 to 20 addition pages over the 64-day window, with a typical small/mid-sized batch in the high single digits to low teens, plus a meaningful chance of one large Iran/shipping-related package. I explicitly keep a fat right tail because 2025 shows that a single OFAC action can add well over 100 SDN entries, but I do not assume that such a shock is the default outcome every summer. That logic puts my median in roughly the 150 area and my mean in the mid-160s, with substantial upside skew. (home.treasury.gov)
Final forecast: I center the outcome at about 160 added SDN entries between June 9 and August 11, 2026, UTC inclusive. My 80% subjective range is roughly 70 to 300, and my 95% range is roughly 25 to 550. The main downside case is that the recent pre-window burst fades and OFAC mostly issues smaller counterterrorism or narcotics batches; the main upside case is another major Iran- or sanctions-evasion-related package resembling the very large July 30, 2025 action.
I treat this as a lumpy batch-count problem, not a smooth-rate problem. OFAC’s own recent-actions workflow shows sanctions updates arriving as discrete actions, and as of June 2, 2026 the recent-actions page showed a dense late-May/early-June cadence. On June 2, 2026 alone, OFAC added 6 individuals and 4 entities to the SDN List. (ofac.treasury.gov)
For scale, Treasury said annual new listings had risen from 880 in 2017 to over 3,000 in 2024. A naive straight-line conversion of 3,000 listings over a 64-day window would be at least about 526 listings, but I treat that only as an upper-end activity benchmark, not a direct summer-2026 SDN forecast, because OFAC acts in bursts and the program mix varies. The same May 28, 2026 Treasury release was about removing 76 outdated targets, which is a reminder that additions and removals are separate processes and that list-maintenance activity can coexist with new designations. (home.treasury.gov)
The best comparable signal is the pattern of actions in the same part of the calendar. OFAC’s 2025 recent-actions listings show sanction-update days throughout the June 9-August 11 window, including June 9, 10, 12, 18, 20, 24, July 1, 3, 22, 24, 25, 30, 31, and August 6, 7, 11. Representative batches ranged from a single addition on June 24, 2025 to 8 additions on July 1 and 6 additions on July 17; June 20 and July 3 were broader multi-program batches. That looks more like a low-hundreds window than a 500-plus window. (ofac.treasury.gov)
Current 2026 conditions push me above that quieter 2025 comparison. In 2026, Treasury sanctioned 23 individuals and entities tied to a Sinaloa Cartel support network on April 23, designated 5 individuals and 7 companies in Nicaragua on April 16, and continued to describe its Iran campaign in January 2026 as part of a “maximum economic pressure” effort. Those signals imply a meaningfully active sanctions environment for summer 2026, especially for Iran-, terrorism-, cartel-, and related programs. (home.treasury.gov)
My forecast therefore centers on an active-but-not-2024-extreme window. I model the total with a 3-component negative-binomial mixture: a baseline active scenario, an elevated scenario, and a major-batch scenario. The mixture mean is 162.5 additions, which is also my point forecast. In words: I think the most likely outcome is in the low-to-mid hundreds, with a real right tail if OFAC executes one or two unusually large Iran, Russia, or cartel designation rounds. My rough median is around 154, my rough central 80% range is about 90-265, and my rough 95% range is about 45-430. (home.treasury.gov)
I anchor this forecast to official OFAC publications. OFAC’s Recent Actions pages publish the sanctions list updates used for real-time SDN changes, and OFAC’s archive/current-year SDN change files state that they store when names were added, modified, or removed. That is the same source family the resolution criteria point to, so I treat OFAC’s own postings as ground truth for estimating the upcoming count. (ofac.treasury.gov)
For base rate, Treasury said the number of annual new listings increased from 880 in 2017 to over 3,000 in 2024. A straight-line conversion of 3,000 annual additions into a 64-day window is about 526 additions. I do not use 526 as a literal point forecast because OFAC designations arrive in irregular batches and 2026 is not guaranteed to match 2024 exactly, but it does show that a several-hundred-entry outcome over June 9 to August 11, 2026 is entirely plausible. (home.treasury.gov)
The near-term operational tempo is clearly active. The Recent Actions index shows sanctions-list-update addition days on April 15, 16, 17, 21, 23, 24, 28, 30; May 1, 7, 8, 11, 18, 19, 20, 21, 27, 28, 29; and June 2 — 20 separate dates in 49 days. On fully enumerated official update pages, recent batch sizes range from 1 addition on April 30 and May 27, to 9 on May 21, 10 on May 18 and June 2, 11 on May 11, 12 on May 8, 13 on May 20, 25 on May 28, and a very large 60 on May 19. That is exactly the kind of bursty process that can build a large total over only two months. (ofac.treasury.gov)
April was also busy before the late-May run. Treasury’s April 15 press release said it sanctioned more than two dozen individuals, companies, and vessels in an Iran oil-smuggling network; the April 16 Nicaragua action targeted five individuals and seven companies; and the April 23 Sinaloa-cartel action targeted 23 individuals and entities. Treasury’s 2026 press releases repeatedly frame the Iran campaign as an aggressive, ongoing pressure effort, which makes continued designation activity through June and July more likely than a sudden collapse to near-zero. (home.treasury.gov)
My synthesis is therefore a center in the high 300s: below the simple 2024 straight-line base rate, but above any lowball estimate that assumes recent large batches were one-offs. I model the outcome as an overdispersed count process with a lull scenario, a baseline scenario, and two upside scenarios for additional large Iran/cartel/terror-finance waves. The code’s implied mean is about 386 additions. In plain language: I think the most likely result is a few hundred additions, with meaningful probability of something in roughly the low-200s to mid-500s, and a non-trivial right tail if OFAC produces several more multi-dozen-entry actions. (home.treasury.gov)
I anchor this forecast to OFAC’s own publication system. OFAC says its archive page records all changes made to the SDN list, and OFAC FAQ 90 says the agency also offers machine-readable delta files while continuing to record changes in human-readable form in Recent Actions and the archive. For this question, the relevant resolution window is June 9, 2026 through August 11, 2026, UTC inclusive, and the thing that matters is added SDN entries, not removals or pure updates. (ofac.treasury.gov)
On cadence, the nearest analogues are busy. By my count from OFAC’s Recent Actions pages, the June 9-August 11, 2025 span had roughly 17 sanctions-list-update postings, while the same seasonal window in 2024 was also active at about the mid-teens. The immediate run-up to this forecast is similarly dense: OFAC’s 2026 Recent Actions pages show repeated sanctions-list updates from April 15 through June 2, 2026 across Iran, counterterrorism, counternarcotics, DRC, Nicaragua, and related programs. That makes a zero-or-near-zero outcome very unlikely. (ofac.treasury.gov)
Batch size is the main uncertainty. Comparable 2025 actions ranged from small and medium batches—11 designations on June 10, five on June 18, 10 on June 20, eight on July 3, and 22 entities on July 9—to a huge July 30 Iran package in which Treasury said it issued more than 115 sanctions, including more than 50 individuals/entities and more than 50 vessels. Large batches are still very live in 2026: Treasury sanctioned over 30 Iran-linked individuals, entities, and vessels on February 25, 2026; 19 shadow-fleet vessels on April 28; more than a dozen Sinaloa-linked individuals and entities on May 20; and 23 individuals and entities tied to a Sinaloa procurement network in May 2026. Treasury’s FY 2027 justification also says maximum pressure on Iran remained a top TFI priority into FY 2026. (home.treasury.gov)
I do make one moderating adjustment: OFAC says the June 30, 2025 executive order revoked the sanctions authorities that had formed the foundation of the Syria program, so one historical source of SDN additions is now narrower than before. That argues against simply extrapolating the hottest 2025 pace forward without adjustment. (ofac.treasury.gov)
I also adjust upward, modestly, from press-release target counts to SDN-entry counts, because the resolution counts entries on the SDN change log rather than unique underlying targets. On June 10, 2025, Treasury’s press release described 11 designated persons/entities, while the SDN changes PDF for that same action shows separate added entries for multiple spelling variants of at least one target. So press-release counts are useful lower-level signals, but they can modestly understate the SDN-entry total that ultimately resolves this question. (home.treasury.gov)
Putting that together, I model the June 9-August 11, 2026 total as a three-regime mixture over the full-window count: a routine-but-busy regime, an elevated regime with several medium batches, and a surge regime with at least one very large batch. I center those regimes at 155, 255, and 380 entries, with weights 0.45, 0.40, and 0.15, which implies a mean forecast of 228.75 entries. My practical point forecast is therefore about 225 added SDN entries. I keep a wide right tail because OFAC additions are lumpy and a single Iran, cartel, or counterterrorism package can move the total by dozens or even more than one hundred entries in one day.
