Final Rationale

My independent estimate of 14.3% was mechanically low due to partial double-counting of the ineligibility factor across SQ1 and SQ4 — I ACCEPT Challenges 1-3 that the decomposition P(announce|ineligible)*P(ineligible) should yield roughly 0.07*0.8 + 0.93*0.15 ≈ 0.20 given Trump's documented norm-breaking, 'Trump 2028' merchandise, and Bannon's active advocacy. I PARTIALLY ACCEPT Challenge 4: the 934-day window and low bar for 'announcement' (a single Truth Social post or rally declaration could suffice) favor a higher number, though I note Trump has strategic reasons NOT to formally announce (preserving successor leverage, avoiding immediate legal fights). The market at 22% with high orderbook depth but wide spread reflects similar reasoning; I land at 19%, slightly below market because I weight more heavily the strategic downside of a formal announcement for a sitting term-limited president who benefits from ambiguity.

Sub-questions (Fermi decomposition)

Is Donald Trump constitutionally eligible to run for President in 2028 (i.e., would he be barred by the 22nd Amendment or other legal mechanisms)? (w=0.30)
Will Donald Trump be physically and politically active enough by 2027-2028 to plausibly mount a presidential campaign announcement? (w=0.25)
Has Donald Trump signaled interest in or refused to rule out a 2028 presidential run? (w=0.25)
Will the political environment (approval ratings, Republican Party dynamics, legal challenges) be favorable enough for Trump to announce a 2028 run before Nov 7, 2028? (w=0.20)

Planner reasoning

This question hinges primarily on the 22nd Amendment constitutional question. Trump was elected president in 2016 and 2024 — two terms — making him constitutionally ineligible to be elected again under the standard interpretation of the 22nd Amendment ('No person shall be elected to the office of the President more than twice'). The key distinction here is between ANNOUNCING a run (which anyone can do) versus being legally eligible to win. The resolution criteria only requires an ANNOUNCEMENT of a run, NOT actual eligibility or victory. This matters enormously: Trump could announce a run for various strategic, political, or financial reasons even if courts would ultimately bar him. Historical precedent: candidates have announced runs in legally ambiguous situations before. Key mechanisms to assess: 1. **Legal eligibility**: Most constitutional scholars agree the 22nd Amendment bars Trump from a third election. However, Trump allies have floated theories about the Vice President pathway or other loopholes. Courts would likely need to rule before or during a campaign. If there's a plausible legal argument, Trump might announce anyway. 2. **Trump's incentives**: Announcing a run keeps him politically relevant, drives fundraising, deters primary challengers in the Republican Party for other races, and maintains media dominance. These incentives exist even if a run is legally questionable. 3. **Age factor**: Trump will be 82 on Election Day 2028. This is historically unprecedented but not disqualifying by itself. 4. **Political context**: If his second term is successful and popular, incentives to run again increase. If chaotic/unpopular, he might prefer not to. Temporal analysis: Resolution is 934 days away (Nov 7, 2028). A typical presidential announcement cycle would see candidates declare 12-18 months before the election (roughly mid-2027 to early 2028). For YES to occur, Trump would need to: (1) maintain physical/political capacity through 2027-28, (2) have some legal theory permitting a run or simply announce despite legal barriers, (3) decide the strategic benefits outweigh the costs of a likely failed legal challenge. The core tension: the question asks about ANNOUNCEMENT, not eligibility. Given Trump's demonstrated willingness to push legal boundaries and his incentives to remain politically dominant, there's meaningful probability he announces even if legally barred. However, most constitutional experts and likely courts would block an actual candidacy, reducing the strategic value of announcing. The Kalshi market price will be highly informative here.

Information Gaps

No data on Trump's current health status or any medical assessments relevant to his capacity to campaign in 2027-2028
No data on Trump's current approval ratings or second-term policy performance, which would influence incentives to run
No data on whether any court has issued preliminary rulings on 22nd Amendment applicability to Trump's potential third run
No data on internal Republican Party dynamics or whether party leaders are actively discouraging a Trump 2028 announcement
No direct reporting from 2026 (post-January) on Trump's most recent statements about 2028
No information on whether any state election officials have signaled they would bar Trump from 2028 ballots
No data on Trump's fundraising activity for any prospective 2028 committee or PAC

Key Uncertainties

Whether Trump's mixed signals (alternating between 'I won't run' and 'I'd love to') will resolve into a formal announcement or quiet retirement from presidential politics
Whether the 22nd Amendment legal question will be tested in court during 2027-2028, and whether a plausible legal theory emerges that emboldens Trump to announce
Whether Trump's health and cognitive capacity will remain sufficient through 2027-2028 to sustain a campaign announcement
Whether the strategic value of announcing (fundraising, relevance, influence) outweighs the costs of a legally doomed candidacy as the 2028 cycle heats up
Whether a strong successor (Vance, Rubio, or other) consolidates Republican support early, removing Trump's incentive to announce
The gap between 22% (announcement market) and 10% (legal eligibility market) — approximately 12 percentage points — represents market-implied probability that Trump announces despite being legally barred

Market Context

Price: 0.22 · 7d: +0.00 · 30d: -0.01
Volume: LOW-MODERATE — 253 contracts/day average is modest for a major political question · Depth: HIGH — 35,969 contracts depth suggests institutional positioning
Reliability: MEDIUM — High depth but wide bid-ask spread ($0.81) and modest daily volume reduce confidence in price precision; the 22% price reflects market belief that announcement is possible but unlikely, consistent with the legal ineligibility discount and Trump's mixed signals; the related 3rd-term-allowed market at 10% implies roughly 12% probability the market assigns to 'announces despite legal bars'

Low disagreement

sq1: Is Donald Trump constitutionally eligible to run for President in 2028?

Base rate: The 22nd Amendment text is clear — no person elected twice can be elected again. Trump was elected in 2016 and 2024. Standard constitutional interpretation bars him. Virtually all constitutional scholars agree. The VP loophole theory is dubious because the 12th Amendment says no person constitutionally ineligible to the presidency can be VP. Only way eligibility changes: novel court interpretation, constitutional amendment (essentially impossible in timeframe), or creative legal theory accepted by courts. Small residual probability (~7%) for unexpected legal interpretations or novel pathways.

sq2: Will Trump be physically/politically active enough by 2027-2028?

80%

Base rate: Men who reach age 80 have roughly 85-90% chance of living to 82 with maintained function, though campaign-level activity is more demanding. Trump is currently sitting president and actively engaged as of early 2026. As sitting president he has extensive support infrastructure. Main risks: health deterioration, cognitive decline over 2.5 years. Push up because he's already performing presidential duties. ~80% he remains capable enough to at least make an announcement.

sq3: Has Trump signaled interest in / refused to rule out 2028?

92%

This is effectively already resolved YES based on evidence. Trump has repeatedly teased, not ruled out, sold merchandise, and allies like Bannon actively promote it. Even the 'probably not' statements constitute non-rulings out. ~92%.

sq4: Will political environment be favorable enough to announce?

30%

Base rate for term-limited presidents formally announcing a constitutionally barred run: zero precedent. Favorable conditions would require: (a) legal theory gains traction, (b) party supports rather than coalesces around successor, (c) Trump sees strategic benefit. Rand Paul and other candidates emerging, Trump endorsing Vance/Rubio suggests succession dynamic. However, Trump could announce anyway for leverage/relevance. ~30%.

Show full reasoning trace

base rate: No term-limited president has ever formally announced a run for a third term. The 22nd Amendment has never been successfully challenged. Base rate for this type of announcement is effectively 0% historically, but Trump is an unprecedented political figure.

evidence updates: Strong DOWN: 22nd Amendment clearly bars him (~-30% from naive 'he teases a lot so he'll announce' prior). Moderate DOWN: Trump endorsing Vance/Rubio as successors, saying 'probably not' in substantive moments. Moderate UP: Persistent teasing, merchandise sales, Bannon advocacy, Trump's demonstrated willingness to push legal boundaries. Age (82) moderate DOWN.

combination method: Decomposed into P(announce|eligible)*P(eligible) + P(announce|ineligible)*P(ineligible), then multiplied by capacity probability. Sub-question 3 (signaled interest) is evidence but teasing ≠ formal announcement.

final: Trump is almost certainly ineligible under the 22nd Amendment. Even for a norm-breaking politician, formally ANNOUNCING a run (as opposed to teasing) has real costs: immediate legal challenges, ballot access denials, diminished leverage over successors. The more likely path is continued teasing without formal announcement, with his influence channeled through endorsing Vance or another successor. Final estimate: ~15%.

Challenges

The decomposition may be double-counting the ineligibility penalty. SQ1 (eligibility ~7%) is multiplied through, but announcing a run does NOT require being eligible — candidates can and do announce runs that are later legally challenged. The question asks about ANNOUNCEMENT, not successful candidacy. Trump could announce while litigation proceeds. This conflates 'can run' with 'will announce'.
The combination method stated is P(announce|eligible)*P(eligible) + P(announce|ineligible)*P(ineligible), but the final number (0.143) appears closer to just multiplying SQ2*SQ4 or similar. If P(announce|ineligible) is even 15-20% (given Trump's norm-breaking behavior, merchandise, Bannon advocacy), the combined probability should be higher. E.g., 0.07*0.8 + 0.93*0.15 = 0.196, already above the stated 0.143.
SQ4 at 30% seems to embed the ineligibility concern already (noting 'zero precedent' for term-limited presidents announcing). Combined with SQ1's 7% eligibility, the ineligibility factor is being applied twice in the reasoning chain.
The 934-day resolution window is very long. Trump has 2.5+ years to make a single announcement-like statement. Given his track record of 'teasing' and selling 'Trump 2028' merchandise, the bar for what counts as 'announcing' could be met by a single Truth Social post or rally statement. The forecaster should clarify resolution criteria — if loose, probability should be much higher.
The market at 22% with high orderbook depth (35,969 contracts) and the related '3rd-term-allowed' market at 10% implies the market prices ~12% for 'announces despite being barred' — which is a reasonable sanity check that the forecaster's 14.3% isn't wildly off, but suggests the forecaster may be slightly underweighting the 'announce anyway' scenario.

Suggested adjustment: +5pp

The decomposition appears to double-count ineligibility (in both SQ1 and SQ4) and the stated combination formula, if applied with reasonable P(announce|ineligible) ~15-20%, yields ~0.18-0.22. Additionally, the question is about ANNOUNCING not successfully running — a lower bar that Trump's pattern of teasing/merchandise could plausibly meet over a 934-day window. Adjusting up ~5 points to correct the apparent math/decomposition issue, not to match the market.

Market comparison: Forecaster: 14.3%, Market: 22%. The divergence is modest and the market has high depth but low daily volume. The market's implied ~12% for 'announce despite being barred' is consistent with the forecaster's framework, suggesting the forecaster's underweight comes from the combination math rather than different priors. After correcting the double-counting, forecast and market would converge naturally around 18-22%.
