Will the US government be shut down on Dec 12, 2026? — Yes

- [2026-09-02] Trump signed the FY2027 continuing resolution (P.L. 119-103), which funds all 12 appropriations bills at FY2026 levels from Oct 1 through Dec 11, 2026. The Senate passed it 90-6 and the House 370-48 on Sep 1. https://approps.ai/shutdown - [2026-09-17] A CRS report says Congress must enact FY2027 appropriations or another CR before the CR expires. Otherwise a funding gap begins Dec 12, 2026, which is the question date, and it could shut down affected activities. Source: CRS R49353 (the search snippet only; the page returned 403 when fetched). https://www.congress.gov/crs-product/R49353 - [2026-09-01] Tom Cole, the House Appropriations chair, doubted the extra weeks would be enough to pass full-year bills. He suggested the December outcome would be either a yearlong stopgap or a shutdown, and said "We're going to be in a crunch time." https://www.cbsnews.com/news/house-vote-government-shutdown-funding-bill/ - [2026-09-01] The House Appropriations Committee has advanced all 12 FY2027 bills, and the full House has passed 3 of them. None has cleared the Senate Appropriations Committee. Cole blamed Senate Democrats. https://www.cbsnews.com/news/house-vote-government-shutdown-funding-bill/ - [2026-09-28] The approps.ai tracker still showed House 3 and Senate 0 FY2027 bills passed, and no further CR or omnibus was in the chain. It lists the Dec 11 expiry as the next possible shutdown date. https://approps.ai/shutdown - [2026-09-01] The CR deliberately pushes the fight past the Nov 3 midterms. Congress is out of session for nearly all of October for campaigning. So there is no scheduled floor action before the election. https://www.cbsnews.com/news/house-vote-government-shutdown-funding-bill/ - [2026-09-01] The CR carries Democratic-demanded provisions: a block on the OMB grants rule through Dec 11, and a bar on transferring funds to Border Patrol. Both are items that could resurface in December. https://www.nextgov.com/policy/2026/09/shutdown-threat-lifted-house-passes-stopgap-spending-bill/415755/ - [2026-04-30] There were two shutdowns earlier in 2026. The first ran Jan 31–Feb 3. The second was DHS-only and ran Feb 14–Apr 30 (76 days), over immigration enforcement reforms. This follows the 43-day full shutdown of Oct 1–Nov 12, 2025. https://en.wikipedia.org/wiki/2026_United_States_federal_government_shutdowns - [2026-10-17] The OPM operating status feed shows federal agencies in the DC area as "Open". Its archive links show the most recent lapse postings were Jan 31, 2026 and Oct 1, 2025. No lapse is in effect today. https://www.opm.gov/rss/operatingstatus/ - [2026-08-03] The CR deal was reached by Senate Appropriations leaders Collins (R) and Murray (D). They described it as giving time to work on bipartisan appropriations bills. https://www.nbcnews.com/politics/congress/senate-leaders-reach-deal-avert-shutdown-2026-elections-rcna590564 - Timing: the CR runs through Dec 11, and the question resolves at 10:00 AM ET on Fri Dec 12. A shutdown on that date therefore requires a lapse beginning at midnight Dec 11–12 that is not cured by then. The CRS report says the gap would begin Dec 12. The House's earlier Dec 4 CR date was dropped. BOTTOM LINE: Government funding is currently in place and expires at the end of Dec 11, so any shutdown would start right at the question date. Congress has done almost no FY2027 appropriations work in the Senate, and Cole has framed December as a year-long CR or a shutdown. The outcome will depend on the post-midterm lame-duck deal, and I found no news from the last 7–14 days on it. NOT FOUND: Any news from Oct 3–17, 2026 on December funding strategy, such as an omnibus, a full-year CR or White House positions. Also any OMB shutdown directive, any statement of the lame-duck schedule, and the CRS page text (403).

- [2026-09-02] Confirmed by CRS: H.R. 6500 (P.L. 119-103) funds all 12 appropriations bills through Dec 11, 2026. CRS says a funding gap would begin Dec 12 unless Congress enacts FY2027 bills or another CR. The search snippet only, because the page returned 403 when fetched. https://www.congress.gov/crs-product/R49353 - [2026-10-13] Jones Walker outlook (fetched) names four scenarios for the lame-duck session: pass some or all of the 12 bills, extend the CR into early 2027, let funding lapse on Dec 12, or enact a full-year CR. It treats the scenarios as not mutually exclusive. https://www.joneswalker.com/en/insights/blogs/perspectives/fy2027-federal-funding-appropriations-outlook.html?id=102o56l - [2026-10-11] GovFedPath: Congress returns Nov 9. As of mid-October none of the 12 FY2027 bills had passed both chambers. https://gofedpath.com/insights/continuing-resolution-fy2027/ - [2026-09-02] The CR passed the Senate 90-6 and the House 370-48. Both parties wanted to avoid an eleventh-hour scramble. This is a strong bipartisan sign, but it covers the October deadline, not December. https://spacepolicyonline.com/news/house-clears-fy2027-cr-now-to-the-president/ - [2026-07-26] The House had passed a competing CR to Dec 4 (H.R. 9770, 220-205), mostly along party lines. The chambers settled on Dec 11. FY2027 status as of July 1: House passed 2 of 12 bills, Senate 0 (fedtools). https://www.fedtools.com/blog/government-shutdown-october-2026 - [2026 history] Recent base rate is high. The Oct 1 – Nov 12, 2025 shutdown lasted 43 days. A 4-day lapse followed on Jan 31 – Feb 3, 2026. A DHS-only shutdown ran Feb 14 – Apr 30, 2026 (76 days). https://en.wikipedia.org/wiki/2026_United_States_federal_government_shutdowns - [2026-06-11] The Jan 30 deadline was missed even after a CR was in place. The DHS lapse was caused by ICE/CBP disputes. This shows that mid-year deadlines can lapse. https://www.crfb.org/blogs/appropriations-watch-fy-2026 - [Pre-2025, from general knowledge, not verified in this session] Lapses since the 1990s are rare relative to the number of deadlines. Pre-holiday December deadlines usually end in a CR or omnibus. The Dec 2018–Jan 2019 shutdown and the near-miss in Dec 2024 are exceptions. Note the 2025–26 cluster of three lapses in about 7 months is unusual. - [2026-09-16] Polymarket snapshot (via polymarkettrader.com, a third-party aggregator): the Oct 1 shutdown markets collapsed to about 1¢ after the CR. A combined "another shutdown by Jan 31 & House winner" market had a thin $337K volume. I found no Dec 11 or Dec 12 odds. https://polymarkettrader.com/events/us-government-shutdown-october-2026/ - [2026-09-22] Context from the Dec 11 deadline: it falls 38 days after the Nov 3 midterms, during the lame-duck session. Jones Walker notes that extending past Jan 3 would shift talks to a new Congress. https://www.joneswalker.com/en/insights/blogs/perspectives/fy2027-federal-funding-appropriations-outlook.html?id=102o56l - [2026-10-02] Trackers show the government fully funded and the next lapse possible only on Dec 12. Even a brief lapse starting Dec 12 would resolve Yes if it is in effect at 10:00 AM ET. Dec 12 is a Saturday, which matters for timing. https://governmentshutdowntracker.com/ BOTTOM LINE: The historical base rate for a lapse at any given CR expiry is low, roughly 10–15% by my own recollection rather than a sourced figure. Two things point the other way: three lapses in the past 12 months, and the lame-duck setting after midterms. The Dec 11 deadline is a Friday, so a deal or short CR could pass within the final days. The overwhelming 90-6 and 370-48 votes on the September CR show a strong bipartisan preference to avoid shutdowns. NOT FOUND: Dec 11/12 shutdown market odds or expert probability estimates; any reporting after Oct 13 on lame-duck negotiating plans; a fetched primary CRS text (403).

YES means: A lapse in appropriations begins at midnight after Dec 11, 2026 and is still in effect at 10:00 AM ET on Fri Dec 12, 2026, with the government at least partially shut down. A shutdown that begins after Dec 12 does not count. - [2026-09-29] The Akin Gump read is that the White House's Sept 25 pocket-rescission package ($810M, 11 items) makes statutory guardrails on OMB "necessary" for any December deal. That is a new precondition Democrats can use to refuse a clean extension. Senate appropriators are also unlikely to act on FY27 bills before Election Day. Roughly five legislative weeks will remain after the election, and Senate bills may not even be posted before then. Akin names three outcomes: full-year bills, a CR, or a "CRomnibus". https://www.akingump.com/en/insights/blogs/the-approps-drop/omb-reaches-for-congresss-purse-strings-but-december-is-coming - [2026-09-29] Collins called the rescission package a "clear violation of the law" and said Congress got no warning or consultation. GAO reasserted on Sep 29 that the maneuver is unlawful. Bipartisan anger at OMB is the mechanism that could turn a routine CR into a standoff, because Republican appropriators now want anti-impoundment language that the White House opposes. https://nlihc.org/resource/congress-recess-until-november-9-take-action-october-fight-hud-funding-fy27 - [2026-10-13] The No Labels explainer says the main December fight is over defense. The administration wants a record $1.5T and Senate Democrats reject it. Because FY27 is still at CR levels, any defense topline dispute blocks a full-year bill, and a long CR would still leave the dispute open. Dec 11 is "the only hard deadline". The lame duck starts Nov 9 and runs to Christmas. https://nolabels.org/the-latest/the-2026-lame-duck-session-what-congress-still-has-to-pass-after-the-midterms/ - [2026-10-02] Actum Insights reports that the parties have no agreed lame-duck strategy and that topline talks on defense and non-defense spending have made no progress. Congress has "just four legislative weeks" before Dec 11. Without a topline there is no basis for a conference. https://actuminsights.substack.com/p/congress-crowded-lame-duck - [2026-10-02] Pioneer Public Affairs says OMB's year-end moves tee up "a fraught start" to lame-duck negotiations. It put its Shutdown Report on hiatus until the lame duck. https://pioneerpublicaffairs.substack.com/p/omb-fireworks-at-fiscal-year-end - [2026-10-02, calendar] The Senate scheduled only 8 regular session days in November and 14 in December. Republicans are skeptical they can finish the backlog. That backlog includes the NDAA, a budget resolution and reconciliation 3.0, and the farm bill. Ron Johnson wants a marathon budget-resolution vote series in the lame duck, which would use the same floor time. https://kfor.com/news/washington-dc-bureau/senate-adjourns-until-november-with-republicans-fearful-of-losing-majority/ - [2026-10-13] WilmerHale describes a debt-limit increase and a third reconciliation package as possible lame-duck items. Under its scenario table, if Democrats win the House they have more reason to wait, and Republicans would try to lock in Iran-war and immigration-enforcement money first. Either result lets a partisan fight spill over into funding. https://www.wilmerhale.com/en/insights/client-alerts/20261013-lame-duck-high-stakes-congresss-postelection-agenda - [2026-10-12, Holland & Knight] H&K says a partial shutdown stays possible if disputes over spending levels, riders, defense, healthcare and Trump administration authorities are not resolved before Dec 11. It adds that Community Health Center funding expires Dec 31, so two closely spaced deadlines compete for attention. https://www.hklaw.com/en/insights/publications/2026/10/beyond-the-midterms-congress-faces-converging-year-end-deadlines - [2026-02/03 precedent] Democrats held out on DHS funding for 76 days and Schumer praised the caucus for "held the line" on ICE. NOTUS reported in July that Democrats had a red line against more ICE/CBP money without guardrails, and activist groups were urging them to use every ounce of leverage. The DHS lapse shows Democrats will let a lapse run past a deadline. https://www.c-span.org/clip/us-senate/sen-schumer-says-democrats-held-the-line-on-ice-in-dhs-funding-fight/5198053 and https://www.notus.org/congress/senate-democrats-government-funding-shutdown - [2026-02-xx precedent] Republican leaders framed the earlier lapses as costless for Democrats and said Democrats got no wins. That gives each side a reason to believe the other will blink. https://www.republicanleader.senate.gov/leader-board/research/in-two-record-breaking-shutdowns-senate-democrats-achieve-no-policy-wins-and-cause-a-whole-lot-of-hardship/ - [2025-11 precedent] Johnson and conservatives said in 2025 that they had "PTSD" about Christmas omnibus bills and preferred January CRs. In the 2025 lame duck, the Senate could not get unanimous consent to combine bills and left for Christmas without a package. Those procedural and ideological obstacles remain. https://thehill.com/homenews/senate/5589424-gop-divisions-end-date-funding-bill-shutdown/ and https://rollcall.com/2025/12/19/congress-leaves-for-christmas-closes-the-books-on-2025/ - [Historic analog] In 2015, the previous Dec 11 CR date required two extra short CRs, to Dec 16 and Dec 22. This shows that Dec 11 deadlines often slip. A short bridge CR is the normal escape valve, and it could also be what fails if the Senate needs 60 votes and unanimous consent. https://en.wikipedia.org/wiki/Consolidated_Appropriations_Act,_2016 Single most likely YES path: the Nov 9 lame duck runs into a defense-topline dispute and Democratic demands for anti-impoundment guardrails. Those demands come after the Sept 25 pocket rescission, and reconciliation 3.0 and the debt limit add friction. The 60-vote Senate cannot agree on a bridge CR before the midnight Dec 11 deadline. Even a short lapse that has not been cured by 10:00 AM Fri Dec 12 would resolve Yes. Prerequisites: - No topline agreement. - No CR with anti-rescission language that both the White House and Senate Democrats accept. - No unanimous consent for fast Senate passage in the final days. - Weekend or holiday recesses that prevent a cure before Saturday morning. BOTTOM LINE: The case for Yes rests on a crowded 14-day Senate December calendar, no topline deal, and Democrats' fresh grievance over the pocket rescissions. Democrats also held out through a 76-day DHS lapse earlier this year. The counterpoint is that the Dec 11 deadline falls on a Friday, so any bridge CR passed in the last days would avoid Yes. NOT FOUND: Any statement from Thune, Johnson, Schumer or Jeffries on a December CR vs omnibus strategy dated Oct 3–17, any White House position on a full-year CR, and any market odds. The Hill's Oct 2 lame-duck article was only available as a link and not read in full. The CRS text was not re-fetched, but its search snippet matches the earlier reports.

YES means: the federal government is at least partially shut down because of a lapse in appropriations at 10:00 AM ET on Dec 12, 2026. That would need the Dec 11 CR to expire with no new CR or full-year bill in force. - [2026-10-09] Holland & Knight lists three likely year-end outcomes. They are an omnibus or minibuses, a shorter CR into January or March 2027, or a hybrid. Shutdown is listed only as a "remains possible" tail. Its analysts say a second CR is "a realistic outcome," especially if the midterms produce divided government. Jeffries has said publicly that he favors doing the appropriations bills in the lame duck, so the Democratic leader is not signalling a shutdown strategy. https://www.hklaw.com/en/insights/publications/2026/10/beyond-the-midterms-congress-faces-converging-year-end-deadlines - [2026-09-30] Actum Insights says appropriators need about four weeks to draft and vote on final bills once a topline deal exists. It also says no topline progress has been made and no lame-duck strategy has been agreed. The mechanism is that a short CR needs no topline and is the fast fallback. Congress returns Nov 9, which leaves about 4.5 weeks. Only a short CR is feasible if the topline is not settled. https://actuminsights.substack.com/p/congress-crowded-lame-duck - [2026-09-30] The same source says end-of-year extenders for healthcare and veterans programs "will likely ride on the final government funding measure". Surface transportation and the Farm Bill authorities also expire Dec 11, and another surface transportation extension is likely (per both fetched sources). Many members have a stake in a funding vehicle passing. A CR is a convenient carrier for these extensions. https://actuminsights.substack.com/p/congress-crowded-lame-duck - [2026-09-30] The same source says the lame duck is crowded with NDAA, reconciliation 3.0 and a possible debt-limit increase. House Armed Services expects the NDAA to be agreed before Thanksgiving and voted on later in December. Leaders therefore have a reason to hold the chambers in session through mid-December, and a late-week CR is a standard pre-holiday step. https://actuminsights.substack.com/p/congress-crowded-lame-duck - [2026-10-09] The H&K alert gives a Dec 11 deadline that falls on a Friday, with surface transportation, farm and health authorities all expiring the same day. This is the "must-pass train" pattern. Similar deadlines resolved in 2014 with a CR enacted Dec 12–13 and in 2016 with a CR enacted Dec 10, per CRS lame-duck histories. Those CRs were enacted at or just before expiry. Short lapses at the exact boundary are possible but were not the outcome in those years. https://www.congress.gov/crs-product/R46574 - [2026-09-25] The Senate Democratic caucus has no stated shutdown demand for December. The ones on record are the OMB grants-rule block, impoundment guardrails and the Border Patrol transfer bar, which a CR could extend (per the Sept 1 reporting). In the Sept 20–26 week, Murray and 30 colleagues wrote to Vought on NIH grant control. These are concerns that a clean CR extension with the Sec. 157 block would satisfy. The Senate Democrats' written objection is to the OMB rule, and the CR already contained that block, so repeating it is the obvious cheap fix. https://news.ballotpedia.org/2026/09/25/stopgap-funding-bill-delayes-omb-grants-rule-until-december-11/ - [2026-10-02] Pioneer Public Affairs expects the shutdown fight to begin in the lame duck. Vought's end-of-FY pocket rescission has split Republicans. Collins and Murkowski say anti-rescission language could be added to FY27 bills, and Rounds warned the White House that its actions will undermine negotiations. Republican appropriators are thus siding with Democrats on process, and that lowers the odds of a partisan standoff. https://pioneerpublicaffairs.substack.com/p/omb-fireworks-at-fiscal-year-end - [2026-09-02] The 90-6 and 370-48 votes show that 19 House Republicans voted no, mostly over hemp and grants provisions (per govtschemes). The CR still passed with a supermajority in both chambers, so a Dec 11 CR could pass by suspension in the House. That removes the Rules Committee and a majority-party-only route as obstacles. https://govtschemes.org/government-shutdown-2026-update/ - [2026-09-27] The Political Group forecast for a shutdown starting Dec 12–31 is 24%. Its stated reason for a NO lean is that "another short stopgap into 2027 is cheap for both parties". It also argues that Democrats concluded the 2025–26 shutdowns brought no concrete concessions. This is a third-party estimate, not a market. https://www.thepoliticalgroup.com/forecasts/will-the-government-shut-down-in-december-2026 - [2026-09-22] Resolution technicality: the CRS report says the gap would begin Dec 12. Dec 12 is a Saturday, so a Friday deal would only need to be signed by midnight. Even if a lapse began at 12:01 AM, a signature on Saturday morning before 10:00 AM would cure it. Any lapse that is cured over the weekend would still resolve Yes only if it is in effect at 10:00 AM ET. The Kalshi rule requires OMB shutdown orders or an OPM lapse notice, and a "technical lapse" where OMB tells agencies to continue operations resolves No. https://www.congress.gov/crs-product/R49353 - [2026-10-11] A mid-October retrospective by the American Investigator Substack lists "three possible paths to Dec. 11". The first is a full-year spending agreement, and none of the three paths is a shutdown. No source I found reports a leader, such as Thune, Johnson, Schumer or Jeffries, announcing a plan to let funding lapse. https://americaninvestigator.substack.com/p/congress-avoided-a-shutdown-december - [2026-10-17] The OPM feed in the colleagues' report shows no lapse in effect now. Status quo: a lapse needs an affirmative failure. No appropriations bills are enacted, but a CR requires only a simple bill that the Senate has passed by bipartisan supermajority twice this year (the Aug 8 and Sep 1 CR votes). https://www.opm.gov/rss/operatingstatus/ BOTTOM LINE: The strongest NO case is that a short CR into 2027 is the default fallback. It needs no topline deal, and it can carry the surface transportation, farm and health extenders that expire the same day. Both leaders voted for a clean CR before the election, and the first weekend of a lapse could be cured before 10:00 AM ET Saturday. The counterweight is the 2025–26 lapse record (covered by colleagues). The unresolved topline and impoundment disputes were reported as of Sep 30–Oct 9, and no leader has named a path. NOT FOUND: Any statement from Thune, Johnson, Schumer, Jeffries or the White House dated Oct 1–17 on a December CR or omnibus. Any Kalshi, Polymarket or other market for Dec 11–12 specifically. The CRS page text (the search snippet confirmed its content). Any OMB or OPM shutdown guidance for December.
