Question: whether the U.S. executive branch will publish the operative June 2026 U.S.–Iran memorandum/agreement text (not just summaries, leaks, or foreign postings) by the Aug. 12 deadline. Forecasters agree the resolution hinges on an official executive-branch posting of the operative MOU text; multiple outlets report a short, signed document exists and senior U.S. officials (including VP Vance) signaled intent to release it imminently, with a June 19 Geneva signing ceremony as the natural focal point for publication. Countervailing signals include reported confidentiality, politically sensitive/disputed provisions (ceasefires, sanctions waivers, frozen assets, reconstruction packages), and legal/administrative rules (INARA and public‑posting procedures) that can require transmission to Congress without immediate public posting. Historical analogues split: some preliminary Iran/hostile-party instruments were made public the same day, while sensitive ceasefire texts were withheld or released only after pressure and leaks. Most forecasters therefore place the largest probability mass on publication around June 19–24, with a smaller-but-notable chance of a later, pressure-driven release and an open upper tail—roughly estimated at ~20–35% by some teams—for no qualifying U.S. public release by Aug. 12. Monitor WhiteHouse.gov, State.gov, Treasury/OFAC, Federal Register, and congressional transmittals; only an executive-branch posting of the operative text (including an identified redacted operative text presented as such) will count as resolution.
Forecast: Probability distribution:
Key drivers are (1) the administration’s stated intent to release details soon after the June 15 Reuters report and the planned June 19 Geneva ceremony, versus (2) the strict resolution requirement that an official U.S. source must publish the operative text (not a fact sheet/readout), which creates a meaningful risk of non-qualifying disclosure or no disclosure.
Across the team, Forecasters 2 and 4 place most mass in June 17–24, reflecting the “24–48 hours/this week” signals and the ceremony anchor, but they likely underweight the resolution-criteria risk (summary-only releases are common). Forecaster 1 and (partly) 3 emphasize that risk and the possibility of no qualifying release by the deadline; I agree on direction but think their central tendency is too late given the strong political incentives to show the document if it is indeed short and already signed.
Synthesis: I expect a fast center (late June) but keep a non-trivial open-after tail for (a) bureaucratic/legal/redaction delays that push an actual-text posting into July/August, and (b) the scenario where only summaries are released and the qualifying text never appears by Aug 12 (resolving “After Aug 12, 2026”). This yields a median around June 23 and ~10–20% probability in the open-after tail (encoded by p90+ past the upper bound).
An amateur forecast would tend to (i) treat “details soon/this week” as synonymous with “full text will be posted,” and (ii) put ~95–99% probability on release within a few days of the June 19 ceremony. This forecast improves by explicitly accounting for the resolution criteria (text vs. summaries) and by carrying a realistic open-after tail rather than overconcentrating probability in the next week. Confidence in the improvement is moderate: near-term signals are strong, but the biggest uncertainty is whether the U.S. chooses to publish the operative text at all.
Forecast rationale (numeric):
— Iteration 1 — Overall, the forecasts lean toward a near-term U.S. public release in late June 2026, with the most likely window clustered around the expected June 19 Geneva signing and the days immediately after.
— Iteration 2 — The forecasts largely converge on a June 19, 2026 release window, with the strongest expectation that the U.S. will publish the memorandum text on or very near the Geneva signing ceremony date. The main drivers are:
There is broad agreement that the release is more likely to happen within days of June 19 than much later, but the forecasts also acknowledge a meaningful tail risk. The main sources of delay or non-release are:
Overall, the collective view is a June 19–20 release centered on the signing event, with some probability extending through the end of June and only a modest chance of slipping well beyond that.
— Iteration 3 — Overall, the forecasts converge on a front-loaded release window centered on the reported June 19 signing/ceremony, with the most likely public posting of the memorandum text occurring within days to a couple of weeks after signing—roughly June 19–30. The main reasoning is that if the administration intends to publicize the deal, the text would likely be released soon after the signing event, especially given Trump’s comment that details would be released soon and the general U.S. practice of publishing agreement texts after major diplomatic announcements.
At the same time, the forecasts emphasize several delay risks that keep a meaningful tail into July and early/mid-August:
There is broad agreement that the distribution is heavily concentrated around the signing window, but the forecasts differ in how much weight they assign to a later publication or no qualifying release by the deadline. Some place substantial probability on an official release by late June, while others stress that the full text may remain unpublished or only appear after further processing, creating a long tail past August 12.
Here is a synthesis of the key reasoning from the rationales:
Official Timelines and Historical Precedent Forecasters broadly agree that the focal point for the document’s release is the formal, in-person signing ceremony scheduled in Geneva on Friday, June 19, 2026. Historically, the Trump administration has placed a high premium on public relations, releasing the operative texts of short-form diplomatic agreements on the exact same day as their signing ceremonies to control the global media narrative. Administration officials have provided slightly mixed but tightly clustered timelines: White House briefers and Vice President Vance indicated a release might occur within 24 to 48 hours or “before Friday,” while President Trump stated it would be published “sometime after Friday.”
Legal Requirements and Domestic Pressures The rationales highlight the Iran Nuclear Agreement Review Act (INARA) as a primary catalyst. Under INARA, the administration must submit the text of any nuclear-related agreement to Congress within 5 days. Because the memorandum was reportedly signed electronically on June 14, the deadline lands precisely on June 19. Since congressional transmissions routinely leak, the administration is heavily incentivized to publish the text officially. Furthermore, Iranian state media has already leaked purported drafts boasting of major U.S. concessions, creating immense pressure on the administration from Congressional lawmakers and allies to promptly release the genuine document and counter foreign spin.
Risks of Delay or Withholding Despite strong consensus for a mid-to-late June release, the rationales identify several factors that could push the publication into July, August, or beyond:

The research reports that the U.S. and Iran electronically signed a preliminary Memorandum of Understanding on June 14, 2026, with President Trump announcing on June 15 that the deal was “all signed” and a formal signing ceremony set for June 19, 2026, in Geneva. U.S. officials (a senior administration official to CNN, VP J.D. Vance on CNBC, and President Trump) have given varying public timelines for releasing the full text — most specifically “within 24 to 48 hours” of June 15, “this week” (week of June 15), and “sometime after Friday” (i.e., after June 19) — while Iran’s foreign ministry spokesperson said Iran planned to publish the text “on the day of signing” (June 19). The memorandum is described as roughly 1.5 pages, a very general two-phase document (ceasefire/Strait of Hormuz first, nuclear issues second), and therefore potentially straightforward to release quickly.
Using historical reference classes (notably the JCPOA of 2015, which was released essentially immediately and was subject to a 5-day congressional review requirement), modern bilateral-agreement norms, and the Trump administration’s stated transparency incentives, the research ranks the most likely release window as June 16–19, 2026 (with June 19—the ceremony day—identified as the single most likely date). It lists June 20–22 as a moderate-probability alternative (allowing for brief bureaucratic delay) and dates from June 23 onward as increasingly unlikely absent significant complications (interagency clearance, redactions, UN/Israeli/regional issues). The research also notes no relevant prediction-market data was found and highlights monitoring points including official U.S. sites, the June 19 ceremony, congressional actions, and further statements from VP Vance and State Department briefings.

Factors Favoring Early Release (June 16-19):
Factors That Could Delay Release (June 20+):
No specific prediction markets found for this exact question in my search. This is likely because the question is very recent (opened June 16, 2026 at 06:00 UTC).
HIGH PROBABILITY: June 16-19, 2026
MODERATE PROBABILITY: June 20-22, 2026
LOW PROBABILITY: June 23-August 12, 2026
VERY LOW PROBABILITY: After August 12, 2026 (Never)
The strongest signal is the 24-48 hour timeline (suggesting June 16-17) combined with the “this week” statement and June 19 ceremony. The base rate from the 2015 JCPOA (immediate release) is highly relevant. The main uncertainty is whether Trump’s “after Friday” comment supersedes earlier officials’ statements. Most probable release window: June 16-20, 2026, with June 19 (ceremony day) being the single most likely date given the convergence of U.S. and Iranian statements around that date.
Conditioning on the question not being annulled, and assuming any existing leaks, Iranian/IRGC lists, summaries, or non-operative “framework” documents do not count.
I accept the critic’s main corrections. The strict resolution criterion is doing a lot of work here: a White House fact sheet, press readout, “14-point framework,” or Iran-released text could satisfy public/political expectations while still failing Metaculus. I also agree the non-inclusive percentile format argues for moving dates one notch later around the median; if my central mass is a June 23 release, the displayed median should generally be June 24.
The evidence for early release is still real. CBS reports senior U.S. officials saying the full MOU text would be released in 24–48 hours, and Vance saying the administration planned to release the full text this week, albeit with caveats about diplomatic protocols and technical details. That creates a meaningful June 16–18 spike. But AP also reports Trump saying the memorandum would likely be released after it is signed on Friday, and that some details remain for the 60-day negotiation process, which pushes the main mode into the post-ceremony window. (cbsnews.com)
The main right-tail risk remains strategic ambiguity. Axios reports internal skepticism from Ratcliffe, Rubio, and Hegseth, and says the nuclear elements depend on further negotiation; CBS also notes the text had not been released by U.S. or Pakistani negotiators while Iranian-side lists/claims were circulating. If the operative text is politically awkward or lets each side sell different interpretations, the U.S. may prefer a non-qualifying summary. (axios.com)
I am also putting more weight on calendar friction: June 19, 2026 is a Friday federal holiday, making June 22–24 a natural fallback even if the Geneva ceremony happens cleanly. But this is only friction, not a hard barrier, since the White House can post documents online outside normal business hours. (opm.gov)
New insight I’m incorporating: the Case Act path is weak protection before the August 12 cutoff. State describes 120-day publication timing for international agreements or qualifying non-binding instruments, with exceptions, so eventual legal/public-record publication can happen after this market has already resolved “After August 12.” (foia.state.gov) Conversely, publication mechanics are not the main obstacle: the White House has a demonstrated releases channel for full MOU texts, so if nothing appears by June 26–30, I would update sharply toward intentional non-publication rather than ordinary delay. (whitehouse.gov)
I now put “After August 12” at roughly 15–16%. The distribution is lumpy: early spike, ceremony/post-holiday mode, then a sharp hazard decline.

Conditioning on non-annulment, and assuming any already-eligible release does not count.
I accept the critic’s main point: the forecast should be more bimodal. The key uncertainty is not mainly “does this take until mid-July?” but rather: does the U.S. decide to post the operative text itself on an official executive-branch site, or does it rely on fact sheets, summaries, speeches, leaks, Iranian/mediator releases, or private briefings? The latter pathway can easily miss the August 12 cutoff even if everyone politically says the “deal details” are public.
I still defend the near-term center. The reported facts are unusually release-friendly: the MOU was reportedly electronically signed, a formal Geneva signing is expected Friday, June 19, Vance said the White House hoped to release the text this week, and Trump’s own timing language points to release after Friday rather than to indefinite secrecy. (axios.com) The White House also has recent precedent for publishing the full text of an MOU directly on its site, which makes a clean qualifying release operationally easy if politically desired. (whitehouse.gov)
The critic is also right that “full text soon” is not a guarantee under this question’s strict criteria. Axios reporting on internal skepticism from Ratcliffe, Rubio, and Hegseth, plus the fact that the full text had not yet been published and appears politically ambiguous, supports a real “summary-only / no qualifying U.S. publication” tail. (axios.com) The statutory publication backstop is not very helpful before this market’s deadline: relevant rules contemplate public State Department publication on a 120-day timeline, with exemptions, which would often land after August 12 if counted from mid/late June. (law.cornell.edu)
My revised distribution is therefore: roughly 10% on June 16–18, 30% on June 19, 25% on June 20–23, 7% on June 24–30, 8% on July 1–August 12, and 20% on after August 12 / no qualifying U.S. release by the deadline. The p80 at August 13 should be read as encoding the cutoff/failure bucket, not as a belief that August 13 itself is a likely publication date.

Model’s Answer: Step one is to identify the actual support. This can resolve on any calendar date in U.S. Eastern Time from 2026-06-16 through 2026-08-12, because White House/State/Treasury pages can publish any day, including weekends. There is also a terminal “After August 12, 2026” bucket. I represent that terminal bucket as 2026-08-13 in the percentile output.
Step two is to separate “details released soon” from “qualifying release.” The fine print is strict: a press release, readout, summary, fact sheet, or speech does not count. That sharply lowers the chance that vague promises of imminent disclosure become a resolving event. The biggest hazard is still right around the June 19 Geneva signing window, because if the administration intends to publish the operative text, that is the natural moment.
Step three is to weigh the competing incentives. Early release is helped by Trump and aides signaling the text/details will come soon, by the document being reportedly short/general, and by leaks already circulating. Delay or non-release is helped by the agreement being preliminary, by ongoing 60-day talks on more sensitive issues, and by the common practice of releasing summaries instead of the full operative text.
My central view is that the modal outcome is a release during the signing/immediate post-signing window, but there is still a large “no qualifying release by deadline” risk because of the strict resolution criteria.
The assumptions that matter most are as follows. First, that official promises about releasing the “text” really mean the operative text rather than a summary; I put about a 40% chance that this assumption fails, which would push mass later and especially into the after-deadline bucket. Second, that the June 19 formal signing happens roughly on schedule; I put about a 25% chance this fails, shifting probability into late June or July. Third, that there is no confidentiality/classification or side-letter issue preventing publication of the operative text; I put about a 35% chance this fails, again materially increasing the after-deadline outcome.
An earlier outcome than my median could happen if the U.S. posts the full text immediately before or on the June 19 ceremony to control the narrative; I think the chance of a qualifying release by June 22 is about 41%. A later outcome could happen if the administration releases only summaries/readouts while keeping the operative text unpublished during the follow-on talks; I think the chance of no qualifying release by the deadline is about 23%.

Legal and bureaucratic publication rules allow deferred posting but do not compel immediate release.
Political incentives favor rapid publicizing of a short, showcase memorandum by the executive branch.
Public declarations by senior officials and a scheduled Geneva signing create momentum toward near-term publication.
Operational sensitivity around ceasefire mechanics, sanctions, and frozen funds exerts downward pressure on immediate disclosure.
If the Geneva ceremony occurs as planned, the most likely pivot is a same-day or next-business-day posting.
A partner objection, unresolved annexes, or classification claims would convert a near-term posting into a protracted withholding regime.
Key uncertainties include classified operational terms, side letters that a party may object to publishing, and holiday and administrative timing.
These sensitivities make timing brittle: political will and partner consent will govern whether publication is immediate or delayed beyond the August window.

Detailed reasoning
My analysis suggests a highly concentrated timeline for the release of the U.S.–Iran memorandum, driven by two distinct but related official signals. First, on June 15, 2026, senior administration officials explicitly told news outlets like Reuters and CNN that the text would be released within 24 to 48 hours. This creates a strong probability for release on June 16th or 17th. Second, President Trump and Iranian officials have publicly linked the release to the formal signing ceremony scheduled for Friday, June 19th, in Geneva.
I have weighted the June 19th date most heavily because high-stakes diplomatic agreements are traditionally published in coordination with their formal ceremonial execution to ensure the ‘operative’ version—complete with physical signatures and final formatting—is the one presented to the public. While digital signatures were reportedly applied on June 14th, the presence of Vice President JD Vance and Jared Kushner at a physical ceremony in Switzerland suggests that the administration may prefer the optics of a post-ceremony release.
Market data from Polymarket supports this concentration, with a 71% probability of release by June 19th. The jump in probability from June 17th (34%) to June 19th (71%) indicates that while an early release is possible, the ceremony is the primary catalyst. I have also factored in a ‘cleanup’ period. If the text is not released on Friday, administrative protocols at the State Department or the White House often result in filings being posted on the following Monday or Tuesday (June 22nd–23rd). The memorandum is described as ‘short and general,’ which reduces the time needed for extensive legal or classification reviews, making a prolonged delay into July less likely. However, the requirement that the release must be the ‘operative text’ on an official U.S. government website—not just a press release or a leak—imposes a strict standard that favors coordinated agency publication. My median prediction of 19th June 2026 reflects the point where these administrative and ceremonial pressures converge.
