- Shutdown odds hit 86% as Congress struggles to strike a deal before the Sept. 30 deadline.
- Essential services stay open, but national parks and non-essential agencies face closure.
- Past shutdowns lasted weeks, with the longest stretching 35 days in 2018–2019.
The U.S. is staring down another potential government shutdown as lawmakers scramble for a last-minute deal. With funding set to expire at midnight, political gridlock is raising serious doubts that Congress can reach an agreement in time.
Odds of a Shutdown Keep Rising
According to prediction market Polymarket, the odds of a government shutdown jumped to 86% as of Tuesday morning, Sept. 30, 2025. While optimism briefly surfaced Monday, driving odds as low as 64%, failed negotiations quickly erased hope. The sharp climb reflects growing pessimism that either party will budge before tonight’s deadline.
What’s at Stake If Government Closes
If no deal is struck, “essential” services—like the military, law enforcement, and air traffic control—will keep operating. But “non-essential” operations, including national parks, passport offices, and regulatory agencies, will see closures or severe staffing cuts starting at 12:01 a.m. on Oct. 1.
History of Shutdown Showdowns
The U.S. has seen shutdown battles before. The most recent, in 2018–2019, dragged on for 35 days during Donald Trump’s presidency and became the longest in history. Another major standoff happened in 1995–1996 under Bill Clinton, lasting 21 days. With time slipping away today, history could repeat itself.
