final rationale
Mean of 5 draws (0.31, 0.31, 0.34, 0.34, 0.32) after one crux research pass. (0) Trump's two Dec 29, 2025 vetoes (H.R.131 and H.R.504), sustained Jan 8, 2026, are confirmed by the Senate registry. Still, this market opened Jan 9, 2026, has traded between 27% and 69%, and sits at 34% now. A contract that counted those vetoes would have been a certain YES from launch. Kalshi also ran a separate 2025 veto-count contract. Both facts strongly suggest only a new veto during the contract period counts, so I treat the question as unresolved, with a small residual chance that a literal reading pays out. (a) About 12 weeks remain until Jan 1, 2027. That window includes the lame-duck session starting Nov 9, which has funding, farm bill and other deadlines around Dec 11, and a possible end-of-Congress pocket-veto window in late December. (b) Status quo is NO: no new veto has been recorded through the Aug 25 Senate update or in news through early October. Trump has also lately let bills become law without his signature rather than veto them. (c) NO: the lame duck passes party-line or negotiated bills Trump signs, he keeps using non-signature or threats as leverage, and no veto happens by Dec 31. (d) YES: as in Dec 2025, Congress sends him bipartisan bills he dislikes in the year-end crush, or a war-powers or disapproval resolution, and he vetoes or pocket-vetoes one before year-end. The Kalshi anchor is 34% and falling (-23% over 30 days), and Polymarket's 'veto in 2026' sits at 29.5%. I land slightly below the Kalshi price, at 31%.

Planner reasoning
The Kalshi price is the anchor. The resolution check is whether Trump has already vetoed any bill in his second term; the Senate's veto list and Wikipedia's list of vetoes record this. congress_bills can show any enrolled bills that are pending or were vetoed, and related veto-count markets on Kalshi and Polymarket give a cross-check.

report: current state
- [2025-12-29/30] President Trump issued the first two vetoes of his second term, rejecting bills with bipartisan support that would have aided a Colorado water project (H.R. 131, "Finish the Arkansas Valley Conduit Act") and expanded tribal land in Florida (H.R. 504, "Miccosukee Reserved Area Amendments Act") , both dated Dec 29 per the official record. Source: https://www.senate.gov/legislative/vetoes/TrumpDJ2.htm - [2026-01-08] The first vetoes of President Donald Trump's second term survived separate override votes by the House of Representatives on Thursday; the override vote on the Colorado bill veto failed 248-177, and the Florida override measure failed 236-188 , both falling short of the two-thirds threshold needed. Source: https://www.cnbc.com/2026/01/08/house-vote-overriding-trumps-vetoes.html - [2026-01-08] Per the official Senate vetoes page: President Donald J. Trump has vetoed 2 bills during his second administration — H.R.131 (Finish the Arkansas Valley Conduit Act), veto date Dec 29, sustained by the House Jan 8, 2026 by vote 248-177; and H.R.504 (Miccosukee Reserved Area Amendments Act), veto date Dec 29, sustained by the House Jan 8, 2026 by vote 236-188 . This page was last updated as of 2026-08-25 (per page metadata), with no additional vetoes recorded since. Source: https://www.senate.gov/legislative/vetoes/TrumpDJ2.htm - [2026-01-08] Dozens of House Republicans voted alongside Democrats in a failed attempt to override the first — and so far, only — vetoes of President Donald Trump's second term; Trump has only issued two vetoes thus far since taking office in January 2025 . Source: https://www.foxnews.com/politics/dozens-house-republicans-defy-trump-join-democrats-failed-veto-override-effort.print - [2026-01-14] President Donald Trump on Sunday said he may veto legislation that would extend enhanced subsidies for Affordable Care Act (ACA) enrollees; the House had passed a three-year extension of the subsidies — this was a separate, contingent potential future veto (on ACA subsidies), not yet confirmed to have occurred. Source: https://www.advisory.com/daily-briefing/2026/01/14/health-policy-roundup - [2025-12-31] Historical context: Trump vetoed a total of 10 bills during his first term , showing he has used the veto power before and is not reluctant to do so. - [2026-10-05] The most recent related news involves a White House media-access "veto"/ban dispute (unrelated to legislative bill vetoes), with ongoing litigation over barring certain outlets from Air Force One access.

Source: https://www.senate.gov/legislative/vetoes/TrumpDJ2.htm BOTTOM LINE: The event has already occurred and is confirmed by the official Senate vetoes registry — Trump vetoed two bills (H.R. 131 and H.R. 504) on Dec 29, 2025, both of which survived House override attempts on Jan 8, 2026, meaning this question should already resolve YES well before the Jan 1, 2027 deadline. NOT FOUND: No evidence of any additional vetoes beyond the two from December 2025 as of the most recent official update (Aug 25, 2026) or the most recent news searches (through Oct 7-8, 2026); the threatened ACA-subsidy veto mentioned in January 2026 does not appear to have been confirmed as issued in subsequent coverage found.
report: base rate
- [2026-08-25] Official U.S. Senate tally confirms President Donald J. Trump (2025-2029) has issued 2 regular vetoes, 0 pocket vetoes, 2 total, with 0 overridden , establishing this as a confirmed historical fact, not a projection. https://www.senate.gov/legislative/vetoes/vetoCounts.htm - [2025-12-29] Trump vetoed two bipartisan bills on the same day: H.R.131 - Finish the Arkansas Valley Conduit Act and H.R.504 - Miccosukee Reserved Area Amendments Act . https://ballotpedia.org/Donald_Trump:_Vetoed_legislation,_2025-2026 - [2026-01-08] Congress attempted overrides of both vetoes; the override vote on the Colorado bill veto failed 248-177, with one member voting present, and the Florida override measure failed 236-188 , meaning both vetoes are sustained and final. https://www.cnbc.com/2026/01/08/house-vote-overriding-trumps-vetoes.html - [2025-12-31] Reporting notes the historical override base rate is low: to override his vetoes, both houses of Congress would need to vote by a two-thirds margin — a feat rarely achieved; Congress has done it before to Trump, overriding his veto of a defense funding bill at the end of his first term (the FY2021 NDAA, his only override in term one). https://www.axios.com/2025/12/31/trump-vetoes-water-pipeline-everglades-bills - [2025-12-31] Base rate from Trump's first term: Trump vetoed 10 bills during his first term; only one of the vetoes was overridden by Congress. The first veto came two years into his term — showing his first term also eventually produced vetoes, but not until year two; this second term's first veto came much faster (within the first year). - [n.d.] Outside-view/base rate across modern presidencies: Senate.gov historical data shows every full-term president since Eisenhower has issued at least one veto: Joseph R. Biden, Jr. (2021-2025) 13; Barack Obama (2009-2017) 12; George W. Bush (2001-2009) 12; William J. Clinton (1993-2001) 37; George H. W. Bush (1989-1993) 44 , indicating that issuing at least one veto in any ~2-year window with active legislating is historically the norm for presidents, not an outlier. - [2026-03-08] Trump has shown a pattern of using veto threats as leverage in later 2026 legislative fights, e.g. over a government-funding standoff: Trump can veto any bills sent to him and send them back to Congress, which can override his veto with a two-thirds majority in each chamber. If Congress adjourns, the president also can let the bill sit for 10 days, and it will not become law — a procedure known as a "pocket veto." https://www.cnbc.com/2026/03/08/trump-save-america-act-voter-id.html - [2026-10-05] More recent reporting shows Trump has instead been using "pocket" non-signature tactics (bills becoming law via the 10-day rule without his signature) rather than new vetoes in 2026: Even so, the tactic appears to be exceedingly rare in the modern Congress. A search on Congress.gov indicates that nine measures have become law in the same manner in just over the past half-century, including the two bills under Trump. This shows Trump sometimes lets bills become law without signature rather than vetoing, but this does not negate the already-completed vetoes. https://rollcall.com/2026/10/05/as-congress-leans-on-pro-formas-bills-become-law-without-trump-signature - [2026-06-24] Trump has also repeatedly threatened to withhold signature/veto on bills as negotiating leverage (e.g., a housing bill and the SAVE America Act), showing continued willingness to use veto-type powers through mid-2026. https://thehill.com/opinion/white-house/5948333-pocket-veto-trump-congress/ BOTTOM LINE: The base-rate reasoning is moot here because the event has already occurred: official Senate records and extensive contemporaneous reporting confirm Trump issued two sustained vetoes on December 29, 2025 (overrides failed January 8, 2026), satisfying the "at least 1 veto before Jan 1, 2027" criterion well within the market's window. NOT FOUND: No market-specific odds were sought per instructions; could not find any dispute or correction to the Senate.gov veto count (2 regular vetoes, 0 overridden) that would suggest this fact is contested.
report: yes case
YES means: Trump vetoes at least one bill or resolution (including via pocket veto) before January 1, 2027 — and since the resolution criteria ask only whether this happens "before Jan 1, 2027" with no requirement that an override fail or that the veto remain unchallenged, a sustained veto issued and recorded at any point in that window satisfies the contract. - [2026-08-25 (page metadata, content reflects Jan 8, 2026 events)] The official Senate registry, fetched directly, states: "President Donald J. Trump has vetoed 2 bills during his second administration," listing H.R.131 (veto date Dec 29) and H.R.504 (veto date Dec 29), each marked "The House *sustained* the veto on Jan 8, 2026" with roll-call vote numbers 9 (248-177) and 8 (236-188) linked to the Clerk of the House's official vote records. https://www.senate.gov/legislative/vetoes/TrumpDJ2.htm - [2026-08-25] The companion Senate tally table confirms numerically: "Donald J. Trump (2025-2029) | 119-120 | 2 | 0 | 2 | 0" (regular/pocket/total/overridden), i.e., 2 total vetoes, 0 overridden — a clean, unambiguous primary-source count that is dispositive for the "at least 1" threshold. https://www.senate.gov/legislative/vetoes/vetoCounts.htm - [2026-01-08] Fox News reporting corroborates the override failures with granular detail: "Thirty-five Republicans joined all 213 Democrats to override Trump's veto" of the Colorado bill, "but it failed to reach the two-thirds majority necessary," confirming the veto's survival is not in dispute. https://www.foxnews.com/politics/dozens-house-republicans-defy-trump-join-democrats-failed-veto-override-effort.print - [2026-01-08] CNBC's contemporaneous account adds the procedural mechanism that forecloses any ambiguity about resolution: "By rule, if a vote to override a veto fails in the House, no vote is required in the Senate, and the veto remains in effect," meaning no Senate vote was even needed to finalize the sustained status of both vetoes. https://www.cnbc.com/amp/2026/01/08/house-vote-overriding-trumps-vetoes.html - [2026-01-02] Independent legal commentary (Legal Planet) corroborates the facts outside government/news sources, noting both bills "passed by voice vote – which means they were unopposed in both the House and the Senate," underscoring that these were genuine, officially transmitted vetoes (not procedural quirks) that Trump affirmatively exercised. https://legal-planet.org/2026/01/02/veto-trouble/ - [2026-06-24/25] A sibling prediction market ("Will Trump issue a veto in 2026?" on Polymarket) explicitly incorporates the same two December 2025 vetoes as the baseline fact pattern, describing them as having occurred and been "sustained by the House in January 2026," while noting traders see room for additional vetoes given ongoing fights (e.g., the housing bill, SAVE America Act standoff) — indicating other markets treat the veto-occurrence fact as settled and are debating only the pace of *further* vetoes, not whether this question's threshold is already met. https://polymarket.com/event/will-trump-issue-a-veto-in-2026-20260624151248095 - [2026-09-30] Even recent opinion journalism (Daily Kos) assumes as settled background that Trump has used and continues to use his veto power this term, discussing strategies to "make President Donald Trump veto" more legislation — consistent with a political environment in which the veto power has already been exercised and remains an active tool, not a hypothetical one. https://www.dailykos.com/stories/2026/9/30/800105387/congress/kill-the-filibuster-and-make-trump-veto-everything-people-want/ BOTTOM LINE: This dimension requires no forward-looking argument: the resolution condition ("at least 1 veto before Jan 1, 2027") was already satisfied on Dec 29, 2025, and finalized without ambiguity when the House failed to override on Jan 8, 2026 (vote Nos. 8 and 9), per the U.S. Senate's own official veto registry and vote-count tables, corroborated by multiple independent news outlets. NOT FOUND: No evidence of any retraction, reclassification, or dispute of the two recorded vetoes' validity on any official record checked (Senate.gov, House Clerk links) through the most recent page update and news searches (through Oct 2026); no indication any Kalshi-specific rule excludes already-completed vetoes occurring before the market's Jan 9, 2026 open from counting (the rules as given specify only "before Jan 1, 2027," not "after market open").
report: no case
YES means: Donald Trump, as President, signs at least one formal veto (including a pocket veto) of a bill or joint resolution passed by Congress at any point before January 1, 2027, per the official U.S. Senate vetoes registry and/or credible news reporting. Having searched specifically for any technicality, override, rescission, or definitional dispute that could rescue a NO outcome, the case is extremely weak. The facts assembled below are the best available counter-considerations, but none plausibly overturns the already-documented vetoes. - [2026-08-25] The official Senate registry metadata (page last updated Aug 25, 2026) lists exactly two vetoes for Trump's second term, both dated Dec 29, 2025, with no revisions, corrections, or retractions to the entries since — i.e., no data-integrity dispute exists that a NO argument could exploit. https://www.senate.gov/legislative/vetoes/TrumpDJ2.htm - [2026-01-08] Both override attempts are recorded as having definitively failed on the floor — the Arkansas Valley Conduit override got only 248-177 (with "35 Republicans" crossing over, "falling 40 votes short of the two-thirds majority needed"), and the Miccosukee override failed 236-188 — closing off any route by which the vetoes could be legislatively erased or recharacterized as non-vetoes. https://www.cpr.org/2026/01/08/house-trump-arkansas-valley-conduit-veto-override-fails/ - [2026-01-08] ABC News confirms both failed overrides left the vetoes standing as the final word, noting "Trump vetoed the bills -- the first of his second term -- in late December," with no subsequent reversal reported. https://abcnews.com/Politics/house-falls-short-overriding-2-trump-vetoes-bipartisan/story?id=129024480 - [2026-01-12/14] The one plausible "forward-looking" NO-relevant thread — Trump's threatened veto of an ACA subsidy extension bill — never matured into an actual veto; Trump only said "I might" veto it if the Senate passed it, and reporting from this period shows the bill faced "an uphill battle" in the Senate with "policy experts do not expect the subsidy extension to survive," meaning this bill likely died in the Senate rather than reaching Trump's desk for a veto or signature. https://www.fiercehealthcare.com/regulatory/legislators-revive-aca-debate-hill-trump-seeks-meeting-insurers - [2026-01-08] Even the narrow "GOP loyalty" framing — that dozens of Republicans crossed over, which some might cite as evidence Trump's veto power is politically fragile — only strengthens the YES case, since it confirms vetoes occurred and were contested but sustained, not erased: "more than 20 Republicans voted to defy Trump's wishes on each measure," yet both overrides still failed. https://www.foxnews.com/politics/dozens-house-republicans-defy-trump-join-democrats-failed-veto-override-effort.print - [2026-10-05] A possible "status quo inertia" argument — that Trump has since avoided new vetoes by letting bills lapse via pocket-veto-adjacent non-signature tactics instead — only pertains to whether a *third* veto occurs; it does not and cannot undo the two vetoes already on the books from December 2025, since the resolution criterion only requires "at least 1" veto before Jan 1, 2027, a threshold already cleared by a wide margin (2 vetoes, 0 overrides, confirmed officially). https://rollcall.com/2026/10/05/as-congress-leans-on-pro-formas-bills-become-law-without-trump-signature - [2025-12-31] The only other conceivable technicality — that the vetoes predate the market's stated open date of 2026-01-09 — does not appear in the rules text, which asks only "If President Trump vetoes at least 1 bills or resolutions before Jan 1, 2027"; there is no language restricting the triggering veto to have occurred after the market's open date, so a literal reading of the rules as given does not support a NO argument on timing grounds. BOTTOM LINE: No credible evidence-based NO case exists for this dimension; official Senate records and multiple independent news outlets confirm two sustained, un-overridden Trump vetoes (Dec 29, 2025) that satisfy the "at least 1 veto before Jan 1, 2027" criterion on a plain reading of the rules, and no subsequent development (ACA veto threat fizzling, pocket-veto-avoidance tactics in 2026) creates any plausible route to undo or disqualify those vetoes. NOT FOUND: No reporting of any legal challenge, congressional resolution, or Kalshi rules clarification disputing that the Dec 29, 2025 actions constitute valid "vetoes" under the question's resolution criteria; no evidence the ACA subsidy bill ever reached Trump's desk for an actual veto decision.

report: crux
CRUX: The decisive fact is whether this Kalshi contract's "before Jan 1, 2027" window counts Trump's two already-completed Dec 29, 2025 vetoes (H.R.131, H.R.504) as satisfying the condition, or whether — despite the literal wording — traders and Kalshi are treating the contract as requiring a *new* veto occurring after the market's Jan 9, 2026 open (i.e., the market is effectively a renamed/rolled "veto again" contract, not a literal "any veto since Jan 20, 2025" contract). Evidence found: - President Donald J. Trump has vetoed 2 bills during his second administration: H.R.131 (Finish the Arkansas Valley Conduit Act) and H.R.504 (Miccosukee Reserved Area Amendments Act), both vetoed Dec 29, with the House sustaining both vetoes on Jan 8, 2026 — this is the official U.S. Senate vetoes registry (senate.gov/legislative/vetoes/TrumpDJ2.htm), updated as recently as Aug 25, 2026 per other sources, still showing only these two vetoes. - Dozens of House Republicans voted alongside Democrats on Jan 8, 2026 in a failed attempt to override the first — and so far, only — vetoes of Trump's second term; both veto override efforts failed, with more than 20 Republicans defying Trump on each measure (Fox News, Jan 8, 2026). - The vetoes and their sustaining override votes were fully resolved by Jan 8, 2026 — one day *before* this Kalshi market opened (Jan 9, 2026). A market literally asking "will Trump veto at least 1 bill before Jan 1, 2027" would already be a certain YES at creation if it counted pre-existing vetoes, which is inconsistent with Kalshi opening a freshly-priced market with meaningful uncertainty. - Separately, Kalshi had a distinct, earlier-dated market, "How many bills will Trump veto in 2025?", forecasting a 23% chance Trump would veto even a single bill before year-end 2025 (ending Jan 1, 2026) — confirming Kalshi runs these as separate, date-bounded instruments rather than one continuous "any veto ever" contract, supporting the inference that the current contract (opened Jan 9, 2026) is a successor instrument focused on the period after its open rather than retroactively crediting Dec 2025 vetoes. - No subsequent (post-Jan 8, 2026) vetoes have occurred: the Senate registry (last confirmed update Aug 25, 2026) still lists only the two December 2025 vetoes, and no news through early October 2026 reports any additional veto. - Current legislative posture favors avoidance of new vetoes: in a recent case Trump chose to let a bipartisan bill become law without his signature rather than veto it, after having 10 days to sign, veto, or allow it to take effect without approval — i.e., he has shown a pattern of withholding signature rather than formally vetoing, which would not satisfy a veto-based resolution. - Looking ahead, the lame-duck session carries veto risk: Congress returns November 9, 2026 to a lame-duck session, with government funding, LIHEAP, and the farm bill all needing resolution, most by December 11 , creating a plausible late-session veto opportunity (echoing the Dec 2025 precedent and Trump's history of NDAA-related veto threats, e.g. White House officials told lawmakers the president would veto the fiscal 2026 NDAA if Congress did not delete certain base-naming language , though that NDAA was ultimately signed, not vetoed, on Dec 18, 2025). BOTTOM LINE: The primary-source Senate registry unambiguously confirms two vetoes occurred Dec 29, 2025, with overrides resolved Jan 8, 2026 — one day before this market opened. The timing and structure (Kalshi's precedent of running separate annually-bounded veto contracts, and the fact that a literal "any veto" reading would make the market a trivial/instant YES at launch) strongly suggest the contract is designed and traded as requiring a *new* veto after Jan 9, 2026, not retroactive credit for the December 2025 vetoes. Evidence thus favors treating this as an open, uncertain question about a potential new veto before Jan 1, 2027 (with meaningful probability given the contentious lame-duck session ahead), rather than an already-settled YES. NOT FOUND: The exact text of Kalshi's official rules/resolution-source page for this specific contract (to see if it explicitly excludes pre-market-open vetoes) could not be retrieved directly; this analysis relies on strong circumstantial and structural evidence (market pricing behavior, Kalshi's history of discrete annual veto contracts, and timing) rather than an explicit rules citation.

(0) Trump's two Dec 29, 2025 vetoes (H.R.131 and H.R.504), sustained Jan 8, 2026, are confirmed by the Senate registry. Still, this market opened Jan 9, 2026, has traded between 27% and 69%, and sits at 34% now. A contract that counted those vetoes would have been a certain YES from launch. Kalshi also ran a separate 2025 veto-count contract. Both facts strongly suggest only a new veto during the contract period counts, so I treat the question as unresolved, with a small residual chance that a literal reading pays out. (a) About 12 weeks remain until Jan 1, 2027. That window includes the lame-duck session starting Nov 9, which has funding, farm bill and other deadlines around Dec 11, and a possible end-of-Congress pocket-veto window in late December. (b) Status quo is NO: no new veto has been recorded through the Aug 25 Senate update or in news through early October. Trump has also lately let bills become law without his signature rather than veto them. (c) NO: the lame duck passes party-line or negotiated bills Trump signs, he keeps using non-signature or threats as leverage, and no veto happens by Dec 31. (d) YES: as in Dec 2025, Congress sends him bipartisan bills he dislikes in the year-end crush, or a war-powers or disapproval resolution, and he vetoes or pocket-vetoes one before year-end. The Kalshi anchor is 34% and falling (-23% over 30 days), and Polymarket's 'veto in 2026' sits at 29.5%. I land slightly below the Kalshi price, at 31%.

(0) Official Senate records show two Trump vetoes, both dated Dec 29, 2025, and both sustained Jan 8, 2026. Those came one day before this market opened. The Kalshi price of 34%, and Polymarket's similar 'veto in 2026' market at 29.5%, show both crowds treating these contracts as needing a new veto after the market opened. Kalshi's practice of running separate date-bounded veto contracts (it had a separate 2025 market) supports that reading. So the condition is not yet met. There is a small residual chance a literal reading would count the December vetoes, but the market would trade near 100% if that were credible. (a) About 12 weeks remain until Jan 1, 2027, including the Nov 9 to December lame-duck session. (b) Status quo is No: no new vetoes appear on the Senate registry (updated Aug 25, 2026) or in news through early October. Trump has recently let bipartisan bills become law without his signature rather than veto them. (c) No: the lame duck passes funding and farm bills negotiated with the White House, and Trump signs them or lets them lapse into law. Any late-December pocket-veto window would likely fall after Jan 1. (d) Yes: as in December 2025, a bipartisan bill he dislikes passes in the lame duck, or a war-powers or disapproval resolution reaches his desk, and he vetoes it before year-end. The market has drifted down 23% over 30 days as time decays, and I see no unpriced catalyst. I anchor slightly below the 34% mid, at about 31%.

The condition is not documented as met: the official Senate second-term registry dates both recorded vetoes to December 29, 2025, outside the supplied prospective-window convention, and January's override votes are not new vetoes. About 85 days remain until January 1, 2027, before which a qualifying regular or pocket veto must occur. I retain Kalshi's live 34% YES anchor (32% bid/35% ask), because the research does not establish a clear informational advantage warranting a departure. If nothing changes, No wins; Roll Call's October 5 reporting that bills became law without Trump's signature illustrates why withholding a signature does not necessarily constitute a pocket veto. A NO scenario is that contentious proposals stall or are negotiated into acceptable legislation, with Trump signing or allowing enactment of everything reaching his desk. A YES scenario is that the reported November 9 lame-duck return and December 11 legislative deadlines produce a funding or other dispute leading to a formal veto, or that an adjournment genuinely enables a pocket veto. The cumulative source tally must be interpreted using the veto dates and classifications rather than its headline count; the registry's August 25 update and unavailable full contract rules leave reporting-lag and settlement-interpretation gaps that limit confidence.

I retain Kalshi's 34% YES anchor (32% bid/35% ask), because the research establishes no sufficiently clear informational advantage to justify moving away. No qualifying veto is documented under the supplied forward-looking date convention: the Senate's TrumpDJ2 registry dates both recorded vetoes to December 29, 2025, so Wikipedia's second-term total and January 2026 override votes do not establish that this contract has resolved. Approximately 85 days remain until January 1, 2027—not the later trading-close time—and if no new qualifying veto occurs, No wins. The official tracker's August 25 update leaves reporting-lag risk, while unavailable full contract rules leave some settlement-interpretation uncertainty; I retain these as modest upside risks within the 34%, rather than accepting the reports' already-YES conclusion. A NO scenario is that contentious proposals stall or are negotiated into acceptable legislation, with Trump signing bills or allowing them to become law unsigned, as Roll Call reported October 5; unsigned enactment is not a pocket veto. A YES scenario is a lame-duck dispute over funding, farm legislation, or another bill producing a regular or genuine pocket veto before the deadline, with the reported November 9 congressional return and December 11 deadlines providing opportunities. Trump's ten first-term vetoes and two December 2025 vetoes demonstrate willingness, but neither that history nor the related Polymarket price of 29.5% establishes a compelling departure from this contract's current consensus.

(0) The official Senate registry documents two vetoes on December 29, 2025, but they preceded this market's January 9, 2026 opening; the live 34% price, separate annual contracts, and same-period Polymarket question strongly indicate that a new veto during 2026 is required, although the unavailable full Kalshi rules leave some interpretation risk. No post-opening veto is recorded, so Trump would still need to issue a regular or pocket veto by December 31, 2026. (a) Approximately 84 days remain until January 1, including a lame-duck session beginning November 9. (b) If nothing changes, the outcome is No because the official tracker still lists only the two December 2025 vetoes. (c) No results if Congress avoids sending Trump an objectionable measure, or if he signs or lets legislation become law without his signature, as recent reporting says he has done. (d) Yes results if a contentious funding, farm-bill, or other lame-duck compromise reaches his desk and he formally rejects it or pocket-vetoes it. I shade Kalshi's 34% Yes anchor down to 32%, consistent with Polymarket's 29.5%, because ten months have passed without a qualifying 2026 veto and recent behavior favors non-signature, while retaining substantial probability for year-end legislative conflict.
