Does the government shut down at the December 11 funding deadline?
Will a lapse in federal appropriations cause the US government to shut down when the current continuing resolution expires on December 11, 2026?
Leans no but a real live risk — both trackers expect Congress probably strings together another stopgap, but this Congress has already lapsed funding twice this year and the defense-topline fight is unresolved
The bull case for a shutdown: this Congress has already shut down twice in 2026 (Jan-Feb, Feb-Apr), a base rate no other recent Congress has matched, the Senate hasn't passed a single FY27 appropriations bill, and the defense-topline dispute ($1.5T White House request vs. a Senate CR that excludes new military funding) remains genuinely unresolved heading into a lame-duck session already crowded with the NDAA, Farm Bill and a possible reconciliation package. The bear case: both the August and September stopgaps passed with overwhelming bipartisan supermajorities (90-6 in the Senate, 370-48 in the House), leadership in both parties has signaled it wants to avoid a 'Christmas shutdown,' another short-term patch is cheap and has already been used twice this cycle, and The Political Group's own base-rate model puts lame-duck funding lapses at just 15% historically even after adjusting upward for this Congress's unusual record.
Resolves Dec 11, 2026 · December 11, 2026 CR expiration — the deadline set by the Sept 1-2 stopgap that averted the October 1 shutdown
Congress averted an October 1 shutdown by passing a stopgap (Senate 90-6 on Aug 29, House 370-48 on Sept 1) that funds the government only through December 11, pushing the fight past the Nov 3 midterms into a compressed lame-duck session that must also handle the FY27 NDAA, the Farm Bill and a possible third reconciliation package. Appropriations progress remains thin: the House Appropriations Committee has advanced all twelve FY27 bills out of committee but only three have passed the full House floor, the Senate hasn't passed any, and both chambers remain split on the defense topline — the White House's $1.5 trillion FY27 request (40%+ above FY26, including $350B via reconciliation) that the Senate's own CR pointedly excluded new funding for. This is fiscal 2026's third funding deadline: the year has already seen two actual shutdowns, a 4-day lapse Jan 31-Feb 3 and a 76-day DHS-only shutdown Feb 14-Apr 30, an unusually shutdown-prone Congress by recent historical standards.
Funding either lapses at midnight on December 11 or Congress passes another appropriations measure (full-year bills or a further stopgap) before then — a discrete, dated outcome with no ambiguous middle state.

Take a side
The government shuts downthis is “yes”
The Senate hasn't passed a single FY27 appropriations bill, the $1.5T defense-topline dispute is unresolved, and fiscal 2026 has already produced two real shutdowns — a base rate this Congress has repeatedly proven willing to hit.
Worth knowing: Historical shutdown-period market moves are small and mixed (S&P 500 has ranged from -3.9% to +9.3% during past shutdowns) and typically fade fast once resolved — don't size this as a crash bet, and remember this specific Congress has also ended both of its 2026 shutdowns relatively quickly once forced to act.
Congress keeps the government funded
Both the August and September stopgaps passed with overwhelming bipartisan supermajorities, neither party wants a shutdown colliding with the holidays or the start of a new Congress, and another short-term patch is cheap and already twice-proven this cycle.
Worth knowing: This isn't a typical low-risk CR vote — fiscal 2026 has already seen two actual lapses, and the unresolved $1.5T defense-topline fight is a genuine, not cosmetic, sticking point heading into a lame-duck session with a packed agenda.
6 sources, leaning both ways
- mixedThe Political Group — Will the U.S. government shut down in December 2026?Forecasts 24% for a shutdown between Dec 12-31, derived from a 15% historical base rate for lame-duck funding deadlines since 1980 (2 of 13 lapsed), adjusted up 10 points for this Congress's unprecedented 2026 lapses and down 5 points for its demonstrated stopgap preference; separately cites Kalshi's own market at 29% for the same window.
- noFederal News Network — House passes short-term funding bill to avoid a shutdown before the electionConfirms the House's 370-48 Sept 1 passage of the stopgap funding the government through Dec 11, deliberately timed to keep a shutdown fight away from the Nov 3 midterms.
- mixedConference Board — Policy Backgrounder: Congress Moves Closer to Avoiding Government ShutdownConfirms the House had passed only three of twelve FY27 appropriations bills on the floor as of the backgrounder's writing, the Senate had passed none and hadn't agreed on toplines, and details the $1.5T White House defense request (40%+ above FY26) that the Senate's CR excludes new funding for, including 'Trump-class' battleships.
- noCenter for Homeland Defense and Security — Early 2026 Government ShutdownsDocuments fiscal 2026's two prior shutdowns in detail: a 4-day lapse Jan 31-Feb 3 affecting roughly half of federal agencies, and a 76-day DHS-only shutdown Feb 14-Apr 30 that ended when Trump signed a funding bill — the base-rate evidence behind this topic's elevated probability relative to a typical CR deadline.
- noBreaking Defense — House passes funding stopgap, averting government shutdown in OctoberCorroborates the Sept 1 House vote and Dec 11 funding horizon from a defense-appropriations angle, noting the stopgap buys time but leaves the FY27 defense topline dispute unresolved.
