When will Trump next remove an independent-agency official after Trump v. Slaughter?

• My median prediction for the next removal of a covered independent-agency official is 20th July 2026.
• The Supreme Court’s June 29, 2026, decision in Trump v. Slaughter has removed the primary legal obstacle to at-will removals by explicitly overruling the 91-year-old Humphrey’s Executor precedent.
• President Trump has demonstrated a consistent willingness to remove independent officials, having already attempted dismissals at the FTC, NLRB, and CPSC during 2025.
• Target agencies with remaining Democratic holdovers include the NLRB (David Prouty) and the EEOC (Kalpana Kotagal), where removals would allow the administration to accelerate policy shifts.
• The timeline is influenced by the July 4th holiday period, which may briefly slow administrative actions, though the President’s stated intent for ‘appropriate action immediately’ suggests a rapid response in the weeks following the ruling.
• Resolution depends on a qualifying official source, such as a White House statement or an agency roster update, which often lags slightly behind the actual private notice of removal.

Key figures

Historical context

The legal foundation for the independence of federal agencies was established in the 1935 Supreme Court case Humphrey’s Executor v. United States, which restricted the President’s power to remove commissioners of ‘quasi-legislative’ or ‘quasi-judicial’ agencies like the FTC. This precedent stood for over 90 years, shielding dozens of multi-member boards from at-will dismissal. However, during his second term beginning in 2025, President Trump aggressively challenged this framework. In March 2025, he removed FTC Commissioner Rebecca Slaughter, and in May 2025, he attempted to terminate three Democratic commissioners of the Consumer Product Safety Commission (CPSC). These actions led to the landmark Trump v. Slaughter ruling on June 29, 2026, where a 6-3 majority officially overruled Humphrey’s Executor, declaring that the President possesses at-will removal authority over members of most independent multi-member agencies because they exercise executive power. The only major exception maintained by the Court was the Federal Reserve Board of Governors, cited in the parallel Trump v. Cook decision on the same day.

Tailwinds

• President Trump’s public statements on Truth Social (June 29, 2026) indicate an intent to take ‘appropriate action immediately’ to exercise his newly confirmed powers.
• The administration has previously demonstrated a high ‘hazard rate’ for removals, attempting multiple dismissals in 2025 even before the Supreme Court provided clear legal authorization.
• The presence of Democratic holdovers at the NLRB and EEOC provides clear targets for an administration seeking to overturn Biden-era regulatory precedents.
• The Slaughter ruling minimizes the risk of successful legal challenges, encouraging the White House to act decisively and without the previous fear of judicial stays.

Headwinds

• The observed federal holiday for Independence Day (July 3-5, 2026) may delay the issuance and publication of official government notices.
• Many independent agencies already have existing vacancies or Republican majorities, which may reduce the immediate pressure to remove remaining minority-party officials.
• High-profile officials may choose to resign voluntarily following the ruling, which would not count as a presidential removal under the specified criteria.
• The White House may prioritize filling existing vacancies through the Senate confirmation process rather than initiating controversial new removals.

Detailed reasoning

My analysis indicates a high probability of a removal action occurring within the first month following the Supreme Court’s decision. This is driven by three primary factors: political incentive, historical behavior, and legal clarity.

First, the administration has a clear political incentive to consolidate power across independent agencies. Agencies such as the National Labor Relations Board (NLRB) and the Equal Employment Opportunity Commission (EEOC) still have Democratic members whose presence prevents the establishment of firm Republican majorities or prevents the administration from reversing Biden-era precedents. The Slaughter ruling provides a ‘green light’ to remove these officials at will, a power the President is expected to exercise to ensure agency actions align with his policy priorities.

Second, the President’s historical behavior suggests a low threshold for such actions. In early 2025, the administration attempted several removals (including officials at the FTC and CPSC) even before the legal landscape was settled. Now that the Supreme Court has explicitly validated this authority, there is little reason to expect a more cautious approach. Trump’s immediate post-ruling social media posts, describing the decision as a ‘BIG WIN’ and pledging ‘appropriate action immediately,’ further reinforce this expectation of swift follow-through.

Third, the legal clarity provided by the Slaughter ruling simplifies the administrative process. Previously, removal attempts often triggered immediate and successful judicial stays. With the overruling of Humphrey’s Executor, the legal barriers that once caused delays in finalizing removals have been largely dismantled. This reduces the ‘cost’ of removals and likely accelerates the timeline for issuing new notices.

However, several factors prevent a ‘day-zero’ prediction. The week following the June 29 ruling includes the July 4th federal holiday, which typically slows down official government communications and administrative filings. Additionally, there is a natural coordination lag as the White House Counsel’s office and agency leadership must vet targets and prepare formal removal notices. Furthermore, some commissioners may choose to resign voluntarily once the legal writing is on the wall; since voluntary resignations do not trigger the resolution criteria, this could paradoxically delay the first qualifying removal reported by an official source.

Given these dynamics, I have modeled a high-hazard window starting in early July, peaking as administrative offices return from the holiday break, and tailing off toward August as the most prominent targets are addressed. The median date of 20th July 2026 reflects a balanced expectation that the administration will act within weeks rather than months, while accounting for the necessary procedural and holiday-related delays.

Key uncertainties

• The primary uncertainty is whether the administration prefers to let terms expire naturally (e.g., Anna Gomez at the FCC on June 30) rather than incur the political cost of formal removals.
• It is unclear how quickly the Federal Register or agency rosters will be updated to reflect removals that occur privately in early July.
• There is a possibility that the first qualifying public source will be a court filing that emerges weeks after a private removal notice is sent.
• The Supreme Court’s carve-out for the Federal Reserve might lead to a more cautious approach for agencies with ‘adjudicatory’ functions that were not explicitly addressed in the majority opinion.

Conclusion

• My median prediction for the next removal of an independent-agency official is 20th July 2026.
• The Slaughter decision has created a unique legal environment where the administration can move to reshape the federal bureaucracy with minimal judicial interference.
• Decision-makers should monitor official White House press releases and agency roster updates for the National Labor Relations Board (NLRB) and the Equal Employment Opportunity Commission (EEOC) as leading indicators of further personnel changes.

Question: whether a qualifying public source (White House/agency/Federal Register statement or court filing) will report a new post–Trump v. Slaughter presidential removal, attempted removal, termination, dismissal, or removal notice of a covered independent‑agency official by 2026‑08‑12. As of 2026‑06‑30 no qualifying source was found, though the Supreme Court’s 2026‑06‑29 Slaughter decision sharply lowered legal barriers to presidential at‑will removal for many multi‑member independent agencies. Forecasters agree that Trump’s 2025 removal wave and historical timing (public documentation often appearing within ~1–9 days) mean any queued removals would likely show up quickly, so risk is front‑loaded into early July; targets flagged include FCC commissioner Anna Gomez, NLRB member David Prouty, and FEC Democrats Shana Broussard and Dara Lindenbaum. Disagreements are mainly over magnitude: most teams assign a minority-to-moderate probability of a qualifying event by Aug. 12 (one model estimated ~42%), while emphasizing a substantial tail for no qualifying public source. Important resolution rules: only official statements or court filings quoting/attaching post‑6/29 removal notices count, not press speculation or pre‑decision removals, and monitors should watch agency rosters, filings, and White House/agency releases.

Forecast Reasoning

All four analysts agree there has been no qualifying public source yet as of 2026-06-30, and that Trump v. Slaughter (2026-06-29) is a strong “hazard-rate” accelerator for removals at independent multi-member agencies. The key uncertainties are (i) whether there remains a politically salient “next target” among covered Senate-confirmed voting members who hasn’t already been removed/neutralized, and (ii) whether the first post-decision action becomes public through a qualifying channel (White House/agency statement, Federal Register, explicit roster update, or a court filing attaching/quoting a removal notice). If a removal is contested, a public court filing can make publication relatively fast; if handled quietly, it may not.

Across the team, medians range from mid-July (Forecasters 1, 3, 4) to late July (Forecaster 2). I discount Forecaster 3’s raw percentile table because it is internally non-monotone around the upper bound (an implementation error with open-tail handling), but I still credit their substantive point that documentation/publication constraints create a meaningful “no qualifying source by Aug 12” tail.

Synthesis: I place the median in mid-July (reflecting Trump’s historically aggressive posture and the immediate legal green light) but not as early as the most aggressive forecast, and I keep a modest open-after tail (~5–10%) to reflect the possibility of no qualifying public source appearing by 2026-08-12.

An amateur forecast is likely to (a) overreact to the legal decision and put too much mass in the first 1–3 days, or (b) anchor on the 2026-08-12 bound and incorrectly stack percentiles at the deadline rather than using past-bound dates to represent “no in-window qualifying source.” My forecast improves calibration by balancing the team’s early-action arguments against operational/documentation delays, and by expressing the beyond-window probability correctly via percentiles strictly after 2026-08-12.

Forecast rationale (numeric):

— Iteration 1 — The forecasts broadly converge on a simple pattern: the Supreme Court’s June 29 decision sharply increased the likelihood of a prompt removal, with July—especially late July—seen as the most likely window.

Main reasoning patterns

• Legal barrier removed: The decision is treated as the key trigger, because it weakened or eliminated the main constitutional obstacle to firing independent-agency officials.
• Behavioral precedent: Trump is expected to act quickly because the administration has already shown a willingness to push removal authority and to reshape independent agencies.
• Near-term incentive to test the ruling: The ruling creates both a legal opening and a political incentive to make an early move, likely before opposition can organize.

Areas of consensus

• High likelihood within weeks: All forecasts place substantial probability on a qualifying removal occurring soon after the ruling.
• July is the center of mass: The median timing clusters in late July (roughly July 23–28).
• Some chance by August 12, but not certainty: Most of the probability is before the cutoff, though not all of it.

Main sources of uncertainty

• Target availability: Some likely officials may already have been removed, making it unclear who the next target will be.
• Administrative mechanics: There may be delays from identifying a target, seeking a resignation first, or preparing formal removal paperwork.
• Definition/measurement issues: A qualifying event requires a public, official source; press reports or accepted resignations may not count.
• Strategic or legal delay: The White House may wait for a better case, agency-specific litigation posture, or broader doctrinal strategy.

Overall synthesis

The shared view is that the post-ruling environment makes a removal highly probable and relatively soon, but the exact date depends less on legal permission than on target selection, bureaucratic timing, and whether the administration chooses to move immediately or hold back for strategic reasons.

— Iteration 2 — Across the forecasts, the dominant view is that Trump v. Slaughter materially lowers the legal barrier to firing independent-agency officials, so the main question becomes how quickly the administration chooses to act, not whether it can.

Shared reasoning patterns

• Legal trigger matters most: The ruling is treated as a decisive change that makes removals at will much easier, especially for commissioners or board members at agencies like the FEC, FCC, NLRB, MSPB, or CPSC.
• Political incentive for speed: Several forecasts expect Trump to move relatively quickly to signal the new authority and capitalize on it before attention shifts.
• Prior behavior matters: Trump’s earlier willingness to remove officials is used as evidence that another removal is plausible soon after the decision.
• Documentation matters: The event is only counted once a qualifying public source confirms it, so some forecasts explicitly allow for a gap between the action and public reporting.

Main points of disagreement

• Immediate vs. delayed action: Some forecasts expect a removal in late June or July 2026, with a meaningful chance by early/mid-August. Others think there was no clear qualifying removal by the August cutoff, pushing the likely timing much later.
• How much remains to be done: Faster forecasts assume there are still obvious politically useful targets and that the administration will act right away. Slower forecasts emphasize that fewer suitable targets may remain, or that the White House may prefer to let terms expire rather than formally remove officials.
• Timing of the median: The spread ranges from mid-July 2026 in the most aggressive view to sometime in 2027 in the more cautious one.

Synthesis

Overall, the forecasts agree that the decision increases the likelihood of a removal and makes the near term the most plausible window, but they differ on whether the administration will act immediately or whether delays, strategic patience, or documentation issues will push the next confirmed removal well beyond the first few weeks after the ruling.

— Iteration 3 — Across the forecasts, the main shared view is that Trump v. Slaughter materially increases the likelihood of a near-term removal of an independent-agency official, because it removes the principal legal obstacle and gives the administration a fresh opening to act.

Key reasoning patterns

• Legal clearance is the central catalyst: The decision is treated as a major shift that could allow removals that were previously blocked or chilled by litigation.
• Speed matters: The administration is assumed to be willing to move quickly once the legal barrier falls, especially if it already has a target in mind and can issue a formal removal notice soon after the ruling.
• Historical aggressiveness supports near-term action: Trump’s prior pattern of challenging independent agencies is used as evidence that another removal is plausible soon.
• Strict evidence requirements create uncertainty: Because a qualifying event needs an official source, not just press reports or rumors, the timing can lag behind private decisions or informal steps.
• Target availability may be limited: Some likely officials may already have been removed or may be close to the end of their terms, which could delay the next clearly documented removal.
• Institutional and political frictions remain: Quorum issues, replacement strategy, lower-court injunctions, and the possibility of waiting for a more favorable moment all push the date later.

Areas of consensus

• The forecast leans toward a front-loaded timing distribution: if another removal happens soon, it is most likely within weeks to a couple of months after the decision.
• There is also broad agreement that a long tail remains, meaning the next qualifying removal could still occur much later if the administration delays or if eligible targets are scarce.

Main disagreement

• The biggest split is how quickly the first post-decision removal will appear in the public record:
  • one view expects it very soon, potentially before the end of the scoring window;
  • another is more cautious, arguing that the absence of a qualifying official source by the cutoff makes an in-window event less likely and shifts the center of mass toward late 2026 or beyond.

Bottom line

The collective reasoning is that the ruling makes a removal soon after June 29, 2026 plausible and somewhat favored, but not assured. The outcome depends on whether the administration can quickly choose a remaining target and generate a formal, publicly documented removal before institutional and evidentiary delays intervene.

Summary of Forecasting Rationales

The Context of the Slaughter Decision The Supreme Court’s ruling in Trump v. Slaughter formally grants the President sweeping authority to fire independent-agency officials at will. However, forecasters emphasize that this ruling serves primarily as a retroactive validation of actions the Trump administration already took. Because the administration aggressively purged Democratic commissioners at major agencies (such as the FTC, NLRB, EEOC, and CPSC) in early 2025, the most obvious ideological targets are already gone. Consequently, there is little pent-up demand for a new wave of immediate, high-profile firings.

Factors Suppressing an Immediate Removal

• The Quorum Dilemma: At agencies like the FCC and NLRB, the few remaining Democratic commissioners (such as Anna Gomez and David Prouty) are practically necessary to maintain an operational quorum. Firing them would paralyze these agencies and stall the Republican majority’s deregulatory agenda until replacements are confirmed by the Senate.
• Voluntary Resignations: The resolution criteria explicitly exclude voluntary resignations. Because the Slaughter ruling eliminates their legal “for-cause” protections, targeted officials know they cannot win a legal battle. It is highly likely they will choose to voluntarily resign to save face if asked, which would avoid triggering a positive resolution.
• Exclusions: The Federal Reserve is explicitly excluded from the resolution criteria, and the companion Supreme Court ruling in Trump v. Cook legally protects Fed governors from at-will removal anyway.

Factors Supporting a Prompt Removal Despite the strategic disincentives, some rationales argue that the administration could act swiftly to flex its newly confirmed constitutional prerogative. The administration has a history of executing sudden personnel changes following major legal victories. There remains a possibility that the White House could target holdovers on lesser-known boards or formally terminate FCC Commissioner Anna Gomez—whose statutory term expires on July 1, 2026—to firmly establish the precedent before the August 12 resolution deadline.

Procedural and Timing Constraints The window for this question to resolve positively is notably brief, ending on August 12, 2026. Forecasters note that bureaucratic friction, such as waiting for the Office of Legal Counsel (OLC) to draft agency-specific memos, could delay executive action. Furthermore, even if a private removal notice is issued, it only triggers a resolution once a qualifying public source (such as a White House statement or a court filing) confirms it, meaning publication lags could easily push the timeline beyond the mid-August cutoff.

Research Summary

The research summarizes the June 29, 2026 U.S. Supreme Court decision in Trump v. Slaughter (6–3) overturning Humphrey’s Executor and holding that the President may remove independent-agency commissioners at will, with a carved-out exception for the Federal Reserve (a separate 5–4 holding protecting Fed governors). It reports that no qualifying removals were reported in the roughly 24 hours after the decision, notes President Trump celebrated the ruling but said he “might not immediately exercise” the authority, and catalogs Trump’s prior removals of independent-agency officials (including FTC commissioners Rebecca Slaughter and Alvaro Bedoya in March 2025 and others) as a historical base rate. The research lists the roughly two dozen agencies affected (e.g., SEC, CFTC, FCC, NLRB, CPSC, NRC, EEOC, MSPB, FERC, FEC), notes current Republican majorities at several key commissions, and highlights that the Fed and FTC commissioners are effectively excluded from new removals (Fed by the carve-out; FTC because the named plaintiffs were already removed).

The research then outlines factors that could push Trump to act sooner (prior removals, resolved legal uncertainty, a looming August recess and legislative calendar) versus factors that could delay action (Trump’s stated restraint, already Republican-leaning agency compositions, political and logistical considerations, and scholarly warnings about instability). It states no prediction-market data were found for this specific question, identifies key uncertainties (Trump’s strategy, target choices, political timing, implementation logistics, and agency reactions), and concludes that while historical evidence shows Trump will use removal power, the unprecedented legal context and his public statement of potential restraint make short-term forecasting (the June 29–August 12, 2026 window) uncertain.

Trump v. Slaughter Decision Summary

On June 29, 2026, the U.S. Supreme Court issued a landmark 6-3 decision in Trump v. Slaughter that overturned the 1935 Humphrey’s Executor v. United States precedent [1][2][11]. This ruling allows President Trump (and future presidents) to remove commissioners from independent federal agencies at will, without needing to demonstrate “inefficiency, neglect of duty, or malfeasance in office” as previously required [1][18]. Chief Justice Roberts wrote that agencies exercising executive power must remain accountable to the President [14][18].

However, the Court carved out an exception for the Federal Reserve, ruling separately 5-4 that Fed Governor Lisa Cook could not be removed without due process [12][16][18].

Current Status (as of June 30, 2026)

No qualifying removals have been reported in the ~24 hours since the decision. While Trump celebrated the ruling on Truth Social as a “major victory” and “historic and unprecedented” expansion of presidential power [19][20], he also stated he “might not immediately exercise the new authority to fire more officials” [14].

Historical Base Rates & Reference Classes

Trump’s Previous Removal Pattern: Prior to the Supreme Court decision, Trump had already removed multiple independent agency officials during his second term [17][27]:

• March 2025: FTC Commissioners Rebecca Slaughter and Alvaro Bedoya (the plaintiffs in the Supreme Court case)
• NLRB member Gwynne Wilcox
• FLRA member Susan Tsui Grundmann
• BLS Commissioner Erika McEntarfer
• National Mediation Board member Deirdre Hamilton

This demonstrates Trump’s willingness to remove independent agency officials, though all of these removals occurred before the Supreme Court validated his authority to do so. The question is whether having clear legal authority will accelerate or decelerate his use of this power.

Agencies and Officials Potentially Affected

The ruling impacts approximately two dozen independent agencies [14][21][25], including:

Multi-member agencies with Senate-confirmed commissioners:

• SEC (Securities and Exchange Commission) - currently has 3 Republican commissioners [24]
• CFTC (Commodity Futures Trading Commission) - led by single Republican chairman [24]
• FCC (Federal Communications Commission) [11][26]
• NLRB (National Labor Relations Board) - Trump already removed Democratic member Wilcox
• CPSC (Consumer Product Safety Commission) [13][21]
• NRC (Nuclear Regulatory Commission) [21][25]
• EEOC (Equal Employment Opportunity Commission) [16][21]
• MSPB (Merit Systems Protection Board) [21][25]
• FERC (Federal Energy Regulatory Commission) [21]
• FEC (Federal Election Commission)

Exclusions per the question:

• Federal Reserve Board members (carved out by Supreme Court)
• FTC commissioners (already subject of Trump v. Slaughter case)

Current Agency Compositions

Based on available reporting:

• FTC: Currently has 2 Republican commissioners (Andrew Ferguson, Mark Meador) and 1 Republican nominee (David MacNiel), against a statutory limit of 3 commissioners from one party [2]
• SEC: 3 Republican commissioners [24]
• CFTC: Single Republican chairman [24]

The current Republican dominance at key agencies may reduce Trump’s immediate motivation to remove additional officials.

Factors Influencing Timing

Factors suggesting earlier action (before August 12):

1. Trump has demonstrated willingness to remove officials (6 prior removals)
2. Legal uncertainty is now resolved in his favor
3. The 44-day window coincides with active legislative period before August recess [24]
4. Potential desire to reshape agencies while momentum from ruling is fresh

Factors suggesting delay or no action:

1. Trump’s own statement about not acting “immediately” [14]
2. Key agencies already have Republican majorities
3. Potential strategic value in waiting to see how agencies respond to the ruling
4. Legal scholars noted the decision may reduce long-term stability and increase “flip flopping” [21], suggesting caution
5. Source [24] indicates Senate negotiations on the CLARITY Act were complicated by this ruling, as Trump could now remove commissioners he appoints later, suggesting political complexity may cause hesitation

Prediction Markets

No active prediction markets were found for this specific question through web searches conducted on June 30, 2026. This represents a notable gap in quantitative forecasting data for this event.

Key Uncertainties

1. Trump’s strategic calculations: Whether he views immediate removals as advantageous or prefers to consolidate the legal victory first
2. Specific targets: Which agencies/commissioners he prioritizes if he does act
3. Political calendar: How July legislative activity (especially CLARITY Act vote [24]) affects timing
4. Implementation logistics: Whether White House needs time to prepare removal notices that meet qualifying source criteria
5. Reaction to ruling: How Democratic commissioners and agencies respond may influence Trump’s actions

Reference Class Analysis

This situation is unprecedented—no president has had explicit Supreme Court authorization to remove independent agency commissioners at will. The closest historical analogs are:

• Trump’s first-term approach to executive power: Aggressive use of removal authority for executive branch officials
• Post-Seila Law (2020): That case invalidated single-director CFPB structure but was narrower than Humphrey’s Executor overturn
• Trump’s March 2025 removals: Occurred before clear legal authority, suggesting he may act even faster now

However, Trump’s statement about not acting immediately [14] and the fact that he’s already removed his apparent priority targets (FTC Democrats) suggest the base rate for action within a 44-day window may be moderate rather than high.

Bottom Line for Forecasting

You’re forecasting on a 44-day window (June 29 - August 12, 2026) with:

• Historical evidence Trump will use removal power (6 prior removals)
• Recent statement suggesting restraint (“might not immediately”)
• Current composition of key agencies already favorable to Republicans
• No immediate post-ruling removals in first 24 hours
• No prediction market data for calibration
• Unprecedented legal landscape making historical base rates less reliable

The question resolves to the datetime of the first qualifying public source announcing a removal, or >2026-08-12 if none occurs.

FORECASTS

R1: Forecaster 1 Reasoning

Updated reasoning:

I condition on the question not being annulled, and assume no already-observed source counts.

I accept the critic’s main direction. The prior 54% was probably a bit high because Trump v. Slaughter is less of a new operational trigger than a validation of removals Trump had already been willing to attempt. The decision clearly expands removal power and overturns the old Humphrey’s Executor barrier, with reporting noting effects beyond the FTC and an exception for the Fed. (supreme.justia.com) But Government Executive reports that Trump had already fired or attempted to fire 20 protected board/commission members by April 2026, so the administration was not simply waiting for final Supreme Court approval. (govexec.com)

The critic is also right that target exhaustion and operational constraints matter more than I initially weighted. Many high-salience targets were already removed or attempted before Slaughter; remaining Democratic/minority commissioners may sometimes be useful for quorum, legitimacy, or statutory party-balance reasons. Removing them may create vacancies without allowing immediate Republican replacements.

I also now put more weight on the resolution-mechanics discount. The market needs an official/qualifying public source, not merely a news story or leaked letter. And because Slaughter weakens the litigation case for fired officials, fewer removals may generate the clean court-filing pathway that would otherwise qualify. Actual removal probability is therefore somewhat higher than resolution probability.

That said, I do not want to move too low. Trump’s demonstrated willingness to remove protected officials remains strong evidence. The ruling affects roughly two dozen multi-member independent agencies, so the option set is broad; a single symbolic or retaliatory removal would resolve the question. (preview.scotusblog.com) A public assertion of the new power could also be politically useful, especially if a commissioner becomes newly defiant or high-profile.

My best estimate is now about 48–50% probability of a qualifying source by 2026-08-12T12:00Z, down from 54%. I model the hazard as: meaningful early spike in the first two weeks; declining but nonzero hazard through late July and early August; substantial no-resolution mass after the cutoff.

I agree with the critic’s main direction and am moving lower again. My prior ~45–46% by 2026-08-12T12:00Z still overweighted “new legal authority → fresh removals” and underweighted that Trump v. Slaughter may mostly validate actions Trump already took. The Court’s account itself centers on the March 2025 FTC removals, and reporting emphasizes that the ruling extends to other agencies where Trump had already fired board members, making this partly an ex-post-confirmation event rather than a new trigger. (supreme.justia.com)

The critic’s quorum point is especially strong. The clearest visible target, FCC Commissioner Anna Gomez, is also useful because her presence helps keep an FCC quorum for Chairman Carr’s agenda; removing her could reduce operational control rather than enhance it. (apnews.com) Similar logic likely applies to other thinly staffed boards: a dissenter can be annoying, but a lost quorum can be worse. I also now put more weight on non-counting substitutes: term expirations, chair designations, nominee confirmations, voluntary resignations, or simple “threat value” from the ruling.

I still would not go much below the high 30s. Trump has repeatedly shown appetite for aggressive removals, the ruling is genuinely sweeping, and its reach plausibly includes agencies such as FERC if a commissioner crosses the administration on a salient issue. (eenews.net) The court-filing/cleanup path also remains live: a post-Slaughter “for avoidance of doubt” removal notice to a previously removed non-FTC official could surface in litigation and score. But I agree this route is less automatic than I previously modeled; DOJ can often just cite Slaughter as supplemental authority rather than generate a new post-decision notice.

A new point I’m incorporating: Trump’s immediate public firing energy may be directed toward Lisa Cook at the Fed, which is explicitly excluded from this question. AP reported that after the paired decisions he said he would still seek to remove Cook “immediately,” but that effort would not count here. (apnews.com) That both confirms his removal appetite and reduces the scoring relevance of some near-term action.

Conditioning on no annulment, I now put the probability of a qualifying public source by 2026-08-12T12:00Z at roughly 39%, maybe 38–40%. Conditional on an event, I still expect July/early August density: either symbolic use of the new power, a lower-profile agency conflict, or litigation cleanup. But the median should be well beyond the cutoff.

Frontier Forecast — Post 549

Modal: Jun 30, 2026 to Jul 07, 2026 (23.5%) • frontier aggregate • 8m30s

Interpret Summary

• Reading: strict
• Type: strict
• Window: Qualifying public sources published after 2026-06-29T00:00:00Z and on or before 2026-08-12T12:00:00+00:00

Edge cases:

• FTC commissioners already named as parties in Trump v. Slaughter are explicitly excluded; any new FTC removals beyond those named parties must be evaluated for coverage.
• A removal notice sent privately but first surfacing in a later court filing resolves to the court filing’s publication datetime, not the date the notice was originally sent.
• Anonymous or rumor-based reports do not qualify even if widely cited; only the enumerated source types count.

Frontier Views (5/5)

• frontier_1 - Modal: Aug 12, 2026 to Sep 24, 2026 (30.0%)

  • The Supreme Court’s June 29, 2026 Trump v. Slaughter ruling newly affirms presidential removal authority over multi-member independent bodies (excluding already-litigated FTC parties).

• frontier_2 - Modal: Jun 30, 2026 to Jul 07, 2026 (18.0%)

  • The Trump v. Slaughter decision (June 29, 2026) overturned Humphrey’s Executor, removing the legal barrier to at-will removal of independent-agency multi-member commissioners.

• frontier_3 - Modal: Jun 30, 2026 to Jul 07, 2026 (40.0%)

  • The Supreme Court decided Trump v. Slaughter on June 29, 2026, granting the President the power to fire independent-agency commissioners without cause, overturning Humphrey’s Executor.

• frontier_4 - Modal: Jul 14, 2026 to Jul 21, 2026 (25.5%)

  • One day after the June 29 decision, no qualifying public source (White House statement, agency notice, Federal Register, roster update, or court filing) has appeared. Searches returned only pre-decision 2025 events and commentary.

• frontier_5 - Modal: Jul 07, 2026 to Jul 14, 2026 (22.4%)

  • The Trump v. Slaughter decision was issued June 29, 2026 (6-3), overturning Humphrey’s Executor and clearing constitutional barriers to at-will removal of multi-member independent agency officials.

Adjudication

• Material notes

  • frontier_3: flag_only/warning - High concentration in the earliest bin is not matched by any cited qualifying public source — this looks like an aggressive translation from general media expectation to a date-resolved qualifying event and may be overconfident.
  • frontier_5: flag_only/warning - Distribution is strongly front-loaded and seems to embody a large base-rate increase — plausible but arguably larger than evidence warrants given unresolved target-composition and mechanism issues.

• Guidance

  • frontier_3 and frontier_5 assign large probability mass to the earliest bin(s) that is not supported by any cited qualifying public source at the timestamp; both appear to have made a large base-rate jump that is larger than the evidence strictly supports.

• Revision

  • Frontier revision skipped: no_selected_adjudicator_reviews.

Supreme Court’s post-Slaughter removal landscape broadens presidential authority but leaves statutory quorums and confirmation gates intact.

Institutional frictions—statutory removal language, quorum thresholds, agency operational needs, and political cost—constrain the pace of further removals.

The administration’s prior pattern of removing commissioners and litigating afterward creates near-term pressure to use the expanded authority.

Public celebration of the decision raises political incentives to demonstrate action against remaining holdout officials.

Clean targets with minimal quorum consequences—small boards, single-seat offices, and agencies with available successors—are the likeliest early inflection points.

High-risk targets tied to safety, national security, or clear quorum disruption create conditional pivots where legal risk, Senate timing, and optics will delay or deter action.

Key uncertainties are the timing and form of an official public notice, the remaining stock of removable officials who do not disable agency function, and the degree of congressional or judicial pushback.

Resolution sensitivity is high to administrative convenience and exposure—an easily documented Federal Register entry, White House statement, or court filing is the decisive trigger for public confirmation.

Forecast: Median = N/A (no P50) — i.e., the most likely outcome is that there may not be a qualifying removal within the near-term window covered by the forecast.

• No immediate action right after the ruling: There was no qualifying report on June 29–30, suggesting the next move is unlikely to be “same-week automatic.”
• Remaining targets look real but lower-urgency: The officials left involve a few prominent holdovers (notably FCC’s Anna Gomez, plus FEC and NLRB Democrats), but the agencies are already partly aligned or not seen as the top blockers.
• Trump’s public hint of restraint: In the immediate post-ruling moment, Trump signaled he didn’t think more firings were coming—taken as mild evidence that timing could be slower.
• High uncertainty about internal readiness: If paperwork/letters were prepared in advance, removal could happen quickly; if not, delays from review and politics likely push it out.
• Big split between “action soon” vs “later/never (for this question)”: Multiple plausible paths lead either to an early-July event or to the outcome occurring after the forecast window, which is why a clean median can’t be pinned down.
