US Fiscal Year 2027 Begins on a Stopgap
- The federal fiscal year 2027 begins on 1 October 2026, the date by which Congress is meant to have enacted all twelve appropriations bills[1]
- Not one of the twelve has passed both chambers; most have cleared House committee and await Senate action[4]
- The rollover passes without a funding gap because H.R. 6500, signed on 2 September 2026, already funds agencies at fiscal 2026 levels through 11 December[3]
- Prediction markets agree: Polymarket's "Government shutdown by October 1?" was trading at about 2 percent for yes three weeks before the date[2]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
