Mean of 5 draws (0.08, 0.07, 0.10, 0.10, 0.09). (0) Resolution check: the condition is not met. Congress.gov data show H.R. 139 passed the House 308–117 on July 14, 2026, then was referred to Senate Commerce on July 15 with no further action. No Senate passage or presidential signature has occurred. (a) About 12 weeks remain until Jan 1, 2027, but the Senate is in recess until Nov. 9. That leaves roughly seven pre-Thanksgiving session days and about three weeks in December before the expected Dec. 18 adjournment. (b) If nothing changes, the bill dies in committee at the end of the 119th Congress, which resolves No. (c) NO scenario: Cotton keeps blocking unanimous consent, and Thune declines to spend scarce lame-duck floor time on two 60-vote cloture votes he publicly doubts can succeed. Daines and Kennedy are also opposed, the medical establishment favors permanent standard time, and the clock simply runs out, as in 2022 when Senate-passed DST died in the House. (d) YES scenario: Trump's escalating public pressure (posting Cotton's phone number, enlisting the PGA Tour) pushes Thune to schedule a cloture vote, or the DST text rides on a must-pass lame-duck vehicle like the NDAA or an omnibus. The Senate then passes it and Trump signs before year-end. None of these steps is currently scheduled. The Kalshi anchor is 9.9% (bid 7, ask 10) and the independent Polymarket crowd is at 9.5%, so the two venues agree. I shade slightly below them because of the compressed calendar, the leadership skepticism on reaching 60, and no evidence of a whip count or vehicle. I keep meaningful tail weight because Trump's pressure is unusually intense and a must-pass attachment is plausible.

- [2026-07-14] H.R. 139, the Sunshine Protection Act, was introduced in the House by Vern Buchanan (R–FL) on January 3, 2025, and passed the House on July 14, 2026 by a vote of 308–117. Source: https://en.wikipedia.org/wiki/Sunshine_Protection_Act - [2026-07-14] The House approved the measure 308–117 on July 14, 2026, and it was referred to the Senate Commerce, Science, and Transportation Committee the following day.

Source: https://www.nbcchicago.com/news/local/whats-the-status-of-congress-permanent-daylight-saving-time-bill/3991843/ - [2026-10-01/02] The House passed the Sunshine Protection Act in July with a 308-117 vote, but the measure has yet to clear the Senate; Senate Majority Leader John Thune (R-S.D.) has also cast doubt on whether the measure can secure the 60 votes needed to advance. Source: https://thehill.com/homenews/senate/6125208-donald-trump-senate-gop-permanent-daylight-savings-bill/ - [2026-10-02] The Senate is on recess and not scheduled to return for legislative business until after the midterms, leaving a narrow window for the chamber to act on the House-passed bill. Source: https://www.washingtontimes.com/news/2026/oct/2/trump-wants-cotton-wake-pass-permanent-daylight-saving-time/ - [2026-10-03] The Senate has adjourned ahead of the Nov. 3 midterm elections, with its next scheduled vote Nov. 9, leaving the measure unlikely to become law before Americans are scheduled to turn their clocks back Nov. 1. Source: https://www.yahoo.com/news/politics/articles/trump-targets-cotton-daylight-saving-171559317.html - [2026-10-03] Sen. Tom Cotton (R-AR), chairman of the Senate Republican Conference, is publicly blocking the bill; he wrote that "Congress has enacted permanent Daylight Savings Time multiple times before and repealed it each time once Americans experienced absurdly late sunrises in the winter." Source: https://www.pbs.org/newshour/politics/trump-urges-calls-to-arkansas-sen-tom-cotton-in-push-for-permanent-daylight-saving-time - [2026-10-04] The bill cleared the House 308–117 and was sent to the Senate, where it has sat in the Commerce Committee; one objection is enough to keep it off the floor, and Cotton has made clear he will be that objection. Source: https://www.thegatewaypundit.com/2026/10/sen-tom-cotton-digs-after-trump-posts-his/ - [2026-10-04] President Trump publicly posted Cotton's cell number urging constituents to pressure him; House members overwhelmingly passed legislation establishing year-round DST by a 308 to 117 vote, but the Senate has not moved on the issue since. Source: https://www.cnn.com/2026/10/03/politics/trump-tom-cotton-phone-number-daylight-saving - [2026-07-21] A companion bill, S. 29, exists in the Senate but the Senate companion bill, S. 29, has not yet passed , and competing proposals (Daylight Act of 2026, Sunshine for Our Kids Act of 2026) remain in circulation, diluting consensus. Source: https://legis1.com/news/permanent-daylight-saving-time-house-passes-bill - [2026-10-05] Clocks are set to "fall back" to standard time on Nov. 1, 2026 under current law, since no permanent-DST legislation has yet passed the Senate; permanent daylight saving time remains a proposal, not an active federal law . BOTTOM LINE: The House passed the Sunshine Protection Act in July 2026, but as of early October 2026 the bill is stalled in the Senate Commerce Committee, blocked by a single GOP senator's objection (Cotton), with the Senate on recess until after the Nov. 3 midterms and leadership doubting it can reach 60 votes; no Senate floor action, presidential signature, or veto override has occurred, so the bill remains far from becoming law. NOT FOUND: Any Senate floor vote schedule or date for Senate consideration of H.R. 139/S. 29 after the midterms; any indication that Senate leadership has committed to bringing the bill up in the lame-duck session before Jan 1, 2027; current vote count/whip count in the Senate.
report: base rate
- [2018-2023] Historical base rate: federal "Sunshine Protection Act"-type permanent DST bills have been introduced 5 times since 2018 (115th–119th Congresses); a reintroduction in 2019 by Vern Buchanan similarly failed, and the 2021 iteration was filed in the U.S. House by Buchanan on January 4, 2021 , with the Senate companion the only version ever to clear one chamber before 2026 — a ~0% full-enactment rate across 8 years of attempts. - [2022-03-15] The only prior full-chamber passage: the Senate on Tuesday unanimously approved a bill that would make daylight saving time permanent beginning in November 2023, earning 17 cosponsors from both parties and passed by unanimous consent ; the House did not take up the bill, and it expired at the end of the same year — illustrating that even unanimous one-chamber passage historically did not translate into law. - [2026-07-14] Current cycle reached a new historical milestone: H.R.139 passed the House by Yea-And-Nay vote, 308 yeas to 117 nays , the first time in over 10 federal attempts the bill passed the House floor. - [2026-07-14] Context on rarity: bills and resolutions to make DST permanent have been introduced over 450 times in state legislatures, while federal legislation has been proposed 10 times, yet until this year DST had never made it to the House floor for a vote . - [2026-10-03] Current Senate dynamic mirrors the 2022 failure mode: Cotton has opposed altering the status quo, and in 2025 he objected to a bipartisan group of senators who sought unanimous consent to pass a similar Daylight Saving Time measure — the same senator whose office privately would have blocked the 2022 unanimous-consent passage. - [2025-11-02] Axios reported a prior 2025 attempt collapsed: the latest push to make daylight saving time permanent collapsed earlier that week after Sen. Tom Cotton blocked Sen. Rick Scott's Sunshine Protection Act — despite support from President Trump , showing presidential backing alone has not been sufficient to overcome a single objector under unanimous consent, and regular order requires 60 votes. - [2026-10-02] Current cloture math is explicitly in doubt: Senate Majority Leader John Thune has also cast doubt on whether the measure can secure the 60 votes needed to advance . - [2026-10-03] Reporting frames near-term odds negatively: Senate Majority Leader John Thune questions whether the bill can attract the 60 votes needed to overcome a filibuster, leaving it unlikely to become law before Americans are scheduled to turn their clocks back on Nov. 1 . - [2026-10-02] Calendar constraint reduces available floor time before the Jan 1, 2027 deadline: the Senate has adjourned ahead of the Nov. 3 midterm elections, with its next scheduled vote Nov. 9, leaving the measure unlikely to become law before Americans are scheduled to turn their clocks back Nov. 1 . - [2026-10-05] No systematic polling/forecaster track record exists specifically for "permanent DST becomes law" (this is a novel, low-N legislative event), but the general base rate for House-passed bills with an identified single-senator objection and sub-60-vote uncertainty clearing the Senate and being signed within roughly 3 months (by Jan 1, 2027) is historically low; most comparable "popular but filibuster-vulnerable" bills that stall in October-November of a midterm year do not resolve before year-end. BOTTOM LINE: The outside-view reference class (8 years, ~10 federal bills, only one prior chamber-passage in 2022 that still died) shows permanent-DST legislation has never become law, and even unanimous one-chamber passage has not been sufficient; the current bill's House passage is unprecedented progress, but the base rate for converting a House-passed, Senate-stalled, single-objector-blocked bill into enacted law within the ~3 months remaining before Jan 1, 2027 is low. NOT FOUND: No dedicated prediction-market or pollster track record specifically forecasting "permanent DST becomes law" odds (e.g., no Polymarket/PredictIt historical base rate data was available in search results); no official Senate floor schedule confirming a cloture vote date on H.R.139 before Jan 1, 2027.
report: yes case
YES means: The Sunshine Protection Act (or an equivalent permanent-DST bill) passes the Senate, is signed by President Trump (or enacted via veto override), and becomes law between now and Jan 1, 2027. - [2026-07-14] The bill cleared its hardest historical hurdle for the first time ever: bills and resolutions to make DST permanent have been introduced over 450 times in state legislatures and 10 times federally, yet until this year DST had never made it to the House floor for a vote, and with newfound advocacy from President Trump, the bill passed the House , removing the single biggest procedural barrier that killed every prior attempt (2018-2025). - [2026-10-03] Presidential pressure is now maximal and public, not just rhetorical: President Trump posted Sen. Tom Cotton's cellphone number and urged supporters to pressure him, writing "Almost everybody wants 'The Sunshine Protection Act' to pass, except for Tom Cotton." This is an unprecedented escalation compared to the quiet 2025 collapse, raising the political cost of continued obstruction. - [2026-10-03] Trump is also mobilizing outside interest groups to widen the coalition beyond Congress, e.g. a letter from PGA Tour CEO Brian Rolapp expressing support for the legislation, with Trump noting "The PGA TOUR, as an example, needs more Daylight in the afternoon in order to finish their Tournaments." - [2026-10-03] Public opinion remains favorable to ending clock changes, which Trump can leverage: a 2025 poll from The Associated Press-NORC Center for Public Affairs Research shows that if forced to choose, most Americans would prefer to keep that extra hour of daylight , giving proponents a persistent messaging advantage even after the Nov. 1 "fall back" deadline passes. - [2026-09-21] Even with Cotton's objection to unanimous consent, Thune has not ruled out a floor vote and left the door open: despite presidential backing, the legislation faces significant resistance in the upper chamber, and Thune indicated senators remain divided on whether there is sufficient backing for 60 votes, saying "There's a lot of interest in it from members on our side over here — some for, some against." - [2026-09-01] A more recent calendar-focused analysis frames the obstacle as scheduling rather than a dead bill: the House-passed bill now faces a Senate floor calendar that has no room for it before November 1, with its first week back locked in for a crypto cloture vote and Cotton's filibuster meaning the bill cannot reach 60 votes in time — implying the blockage is time-constrained, not necessarily permanent, and floor time could open up in the lame-duck session (mid-Nov–Dec 2026) before the Jan 1, 2027 deadline. - [2026-09-01] Thune has pointedly declined to call the bill dead: Thune has not said the bill is dead, has not said he supports it either, and his "Remains to be seen" answer on the 60-vote count is the most precise statement of the bill's position: uncertain, but structurally blocked by a calendar that gives it no room to become certain before November 1 — leaving open a path later in the year. - [2026-10-03] Cotton himself, while objecting, has not claimed unanimous GOP opposition, and reporting notes other skeptics exist but no whip count showing the bill is short by a wide margin: Other Senate Republicans, including Sen. John Kennedy of Louisiana, have also opposed the measure — a short, named list rather than a broad bloc, consistent with the bill being closer to 60 votes than prior iterations. - Mechanism to YES: after the Senate returns Nov. 9 post-midterms, Thune could schedule a cloture vote (not unanimous consent) during the lame-duck session; if 60 votes are secured — plausible given 308-117 House margin, sustained Trump pressure, and bipartisan Senate cosponsorship (companion bill S.29) — the bill could pass, be reconciled with the House text, and reach Trump's desk for signature before Jan 1, 2027. This is the only realistic path, since unanimous consent is blocked by Cotton's objection and pocket-veto/override paths are not at issue given Trump's stated support. BOTTOM LINE: The YES case rests on House passage being unprecedented progress, intense and escalating presidential pressure on the chief objector, favorable public opinion, and Thune's refusal to declare the bill dead — meaning a regular-order cloture vote in the lame-duck session (mid-Nov–Dec 2026) remains a live, if narrow, path to enactment before Jan 1, 2027. NOT FOUND: Any confirmed Senate whip count or vote tally showing ≥60 supporters; any scheduled cloture vote date on the Senate calendar after Nov. 9; any sign Cotton or Thune has softened their stance since Oct. 3-4.
report: no case
YES means: Congress passes, and the President signs (or Congress overrides a veto of), legislation establishing permanent Daylight Saving Time nationwide before Jan 1, 2027 (H.R.139/S.29 or an equivalent bill/joint resolution clearing both chambers and being enacted). - [2026-10-02] The Senate's own 2026 calendar, set before any DST momentum existed, gives the bill almost no room to move: the chamber has the month of October and the first week of November off ahead of the midterm elections and then returns a total of seven days prior to Thanksgiving, and working three weeks in December ahead of the Christmas recess. - [2025-11-19] That same calendar has the Senate adjourning for the year well before the Jan 1 deadline: the Senate is expected to end the year on Dec. 18, a day after House lawmakers are scheduled to depart Washington, as both chambers head into a two-week holiday recess before the 120th Congress convenes the following January. - [2026-09-01] Even before the midterm recess narrowed things further, floor time was already consumed by other priorities: Senate reporting noted the chamber's first week back in September was locked into a cloture vote on the Digital Asset Market Clarity Act, leaving "essentially no opening for a DST vote before November 1," per Tech Times' review of the floor queue (techtimes.com). - [2026-09-01] Sen. Steve Daines (R-MT) has gone beyond generic skepticism to flatly predict the bill "will not 'see the light of day' in the Senate" (techtimes.com). - [2026-09-01] Cotton's objection is not just rhetorical posturing but a stated vote-count judgment: he told The Hugh Hewitt Show that "60 votes for cloture are unlikely to materialize," and a Hill aide said Cotton's opposition "enjoys bipartisan company on the Senate Commerce Committee," indicating the hold is not a single-senator problem but a committee-level bloc (techtimes.com). - [2026-09-01] Thune's own characterization of the vote count, when pressed directly, was noncommittal rather than reassuring: "Remains to be seen" (techtimes.com). - [2026-09-01] The procedural mechanics compound the calendar problem: without unanimous consent, "Senate rules require invoking cloture — a two-step process involving a vote to begin debate and a separate vote on final passage, each requiring 60 senators," meaning even a single floor day is not enough to pass the bill outright (techtimes.com). - [2026-09-01] Medical/scientific establishment opposition adds a substantive (not just procedural) obstacle to any swift deal: AASM, AMA, National Sleep Foundation, Sleep Research Society and the Society for Research on Biological Rhythms "all endorsed permanent standard time" and "explicitly opposed permanent DST," giving Cotton-aligned senators a policy rationale beyond pure obstruction (techtimes.com). - [2026-09-01] The 1973–74 precedent — Congress enacted permanent DST and then "repealed the law" within less than a year after public approval "fell from 79% to 42%" — is being actively cited by opponents as a cautionary tale, reinforcing institutional reluctance to rush a repeat (techtimes.com). - [2026-10-05] No Senate floor vote on H.R.139/S.29 has been scheduled as of the Senate's return; the most recent sourced status (per yesterday's reporting cited by colleagues) still shows "no Senate vote has been scheduled" and the bill "has sat in the Commerce Committee" with one senator's objection enough to keep it off the floor. - [Historical pattern] Even the one prior instance of full one-chamber passage (Senate, 2022, unanimous consent) died without the other chamber acting; the current reverse scenario (House passed, Senate stalled) has an even higher procedural bar (60-vote cloture, not mere inaction) to clear before enactment, and no comparable bill has ever cleared both chambers in the 50+ years since 1974. BOTTOM LINE: With the Senate's calendar structurally capped at roughly seven pre-Thanksgiving days plus three weeks in December before adjourning Dec. 18, a declared objector (Cotton) backed by committee allies who assert cloture is unreachable, no floor vote scheduled, and a competing legislative queue, the mechanical and political barriers to Senate passage, presidential signature, and enactment before Jan 1, 2027 remain very high, favoring a NO resolution. NOT FOUND: Any confirmed Senate floor schedule slot for H.R.139/S.29 in the Nov. 9–Thanksgiving or December work periods; any whip count showing 60 committed yes votes; any sign Thune has agreed to bring the bill up; no evidence of a discharge petition or must-pass vehicle (e.g., NDAA, omnibus) carrying the DST provision.

No Senate passage or presidential signature has occurred. (a) About 12 weeks remain until Jan 1, 2027, but the Senate is in recess until Nov. 9. That leaves roughly seven pre-Thanksgiving session days and about three weeks in December before the expected Dec. 18 adjournment. (b) If nothing changes, the bill dies in committee at the end of the 119th Congress, which resolves No. (c) NO scenario: Cotton keeps blocking unanimous consent, and Thune declines to spend scarce lame-duck floor time on two 60-vote cloture votes he publicly doubts can succeed. Daines and Kennedy are also opposed, the medical establishment favors permanent standard time, and the clock simply runs out, as in 2022 when Senate-passed DST died in the House. (d) YES scenario: Trump's escalating public pressure (posting Cotton's phone number, enlisting the PGA Tour) pushes Thune to schedule a cloture vote, or the DST text rides on a must-pass lame-duck vehicle like the NDAA or an omnibus. The Senate then passes it and Trump signs before year-end. None of these steps is currently scheduled.

(0) The condition is not met. H.R. 139 passed the House 308–117 on July 14, 2026, but it has sat in Senate Commerce since July 15 per congress.gov data. No Senate floor action or signature has occurred, so the Senate must still invoke cloture, pass the bill, and Trump must sign it before Jan 1, 2027. (a) That leaves about three months, but realistic floor time is only about 7 days before Thanksgiving (Senate returns Nov 9) plus roughly three weeks in December before an expected Dec 18 adjournment. (b) Status quo is No: the bill stays bottled up and dies when the 119th Congress ends. (c) No scenario: Cotton (GOP Conference chair) keeps objecting to unanimous consent, and Thune, who has publicly doubted 60 votes, never schedules a two-step cloture process. Lame-duck time goes to funding and nominations, and the bill expires, matching the 2022 pattern where one-chamber passage died. (d) Yes scenario: Trump's escalating public pressure (posting Cotton's number, PGA Tour backing) either gets Thune to spend floor time on a cloture vote that reaches 60 with bipartisan support, or gets the DST text attached to a must-pass year-end vehicle such as an omnibus or NDAA, which Trump then signs in December. The must-pass vehicle path is the main tail risk; no research source shows it being pursued. The Kalshi anchor is 9.9% and the independent Polymarket crowd on the same question is 9.5%. The research adds the Senate's tight calendar, Daines' 'won't see the light of day', and Cotton's committee allies, so I shade slightly below market to about 7.5%.

Kalshi's live 9.9% YES is my anchor, and I retain approximately that probability because the research identifies no clear catalyst the market has missed. As of October 5, no source documents enactment: the bill-status tool records H.R. 139's July 15 Senate referral and October reporting describes continued blockage, although the failed direct Congress.gov read leaves some official-record verification risk. Approximately 88 days remain until January 1, but the reported November 9 Senate return and expected December 18 adjournment compress the practical window; the requirement is enactment before January 1, not implementation before November's clock change. The status quo resolves No, with a straightforward NO scenario being Cotton maintaining his objection and Thune declining to allocate scarce floor time without sufficient cloture support. October reporting from The Hill and PBS supports that bottleneck, and the failed 2022 effort demonstrates that passage through one chamber does not assure enactment. A YES scenario is presidential pressure producing a lame-duck Senate agreement or 60-vote cloture coalition, followed by both chambers approving identical permanent-DST legislation and Trump signing it before the deadline. The reported 308–117 House vote and Trump's support make that path credible, while the research overstates Cotton's procedural power: he can block unanimous consent, not unilaterally veto regular-order passage, and final passage itself ordinarily requires only a simple majority. Missing official live verification, a reliable Senate whip count, and a committed floor slot limit confidence; Polymarket's 9.5% supplies context rather than a second anchor because identical settlement rules were not verified.

No supplied source documents enactment: congress_bills lists H.R. 139's latest action as Senate Commerce referral on July 15, while October 2–4 reporting from The Hill, PBS, and CNN describes continued Senate resistance. About 88 calendar days remain before the January 1 deadline, but the reported November 9 Senate return and planned December 18 adjournment substantially compress the practical legislative window. If nothing changes, the existing clock-change regime remains and this market resolves No. I anchor on Kalshi's 9.9% YES price and round to 10%, finding no demonstrably unpriced development warranting a material departure; the related Polymarket price of 9.5% is corroborating context, not an exact-rules anchor. A NO scenario is that Cotton continues blocking unanimous consent and Thune declines to spend scarce floor time on legislation whose 60-vote cloture support remains unconfirmed, repeating the broader failure of one-chamber passage to produce enactment in 2022. A YES scenario is that the July 14 House vote of 308–117 and Trump's October pressure translate into lame-duck floor priority, sufficient cloture support, Senate approval of the unchanged House bill, and presidential signature before January 1. Cotton's objection is not an absolute veto, and the research overstates the procedural hurdle where it says final passage itself requires 60 votes, but neither correction supplies a scheduled vote or demonstrated winning coalition. The failed direct Congress.gov read leaves verification and source-update risk that limits confidence; importantly, qualifying enactment—not implementation or avoiding the November 1 clock change—is the resolving milestone.

(0) The resolving condition has not already been met: Congress.gov data shows H.R. 139 passed the House but was merely referred to the Senate Commerce Committee, so it must still pass the full Senate and be signed before Jan. 1, 2027. (a) Roughly 88 calendar days remain, but the Senate is recessed until after the Nov. 3 midterms and reportedly expects to adjourn around Dec. 18, leaving only a short lame-duck legislative window. (b) If nothing changes, the bill remains stalled in committee and the market resolves No. (c) The central No scenario is that Cotton maintains his objection, leadership never allocates scarce floor time, or the measure cannot obtain the 60 cloture votes that Majority Leader Thune has questioned. (d) The Yes path is a post-election regular-order vote or inclusion in a must-pass vehicle, followed by rapid Senate passage and President Trump's expected signature, supported by the 308-117 House margin and his public pressure campaign. Kalshi's 9.9% Yes price is closely corroborated by Polymarket at 9.5%; I move only modestly lower to 9% because there is no scheduled vote, verified 60-vote coalition, or must-pass vehicle, while the historical enactment base rate is effectively zero.

Mean of 5 draws (0.08, 0.07, 0.10, 0.10, 0.09). (0) Resolution check: the condition is not met. Congress.gov data show H.R. 139 passed the House 308–117 on July 14, 2026, then was referred to Senate Commerce on July 15 with no further action. No Senate passage or presidential signature has occurred. (a) About 12 weeks remain until Jan 1, 2027, but the Senate is in recess until Nov. 9. That leaves roughly seven pre-Thanksgiving session days and about three weeks in December before the expected Dec. 18 adjournment. (b) If nothing changes, the bill dies in committee at the end of the 119th Congress, which resolves No. (c) NO scenario: Cotton keeps blocking unanimous consent, and Thune declines to spend scarce lame-duck floor time on two 60-vote cloture votes he publicly doubts can succeed. Daines and Kennedy are also opposed, the medical establishment favors permanent standard time, and the clock simply runs out, as in 2022 when Senate-passed DST died in the House. (d) YES scenario: Trump's escalating public pressure (posting Cotton's phone number, enlisting the PGA Tour) pushes Thune to schedule a cloture vote, or the DST text rides on a must-pass lame-duck vehicle like the NDAA or an omnibus. The Senate then passes it and Trump signs before year-end. None of these steps is currently scheduled. The Kalshi anchor is 9.9% (bid 7, ask 10) and the independent Polymarket crowd is at 9.5%, so the two venues agree. I shade slightly below them because of the compressed calendar, the leadership skepticism on reaching 60, and no evidence of a whip count or vehicle. I keep meaningful tail weight because Trump's pressure is unusually intense and a must-pass attachment is plausible.
