The government shutdown is set to start at 12:01 a.m. on Wednesday, October 1, 2025, if a funding agreement is not reached by the end of Tuesday, September 30, 2025. This shutdown will occur because of the failure of Republicans and Democrats in Congress to agree on a spending bill to fund government services beyond the deadline.
The last chance to avert the shutdown is the vote on a funding measure expected around midnight, but as of late September 30, there seems to be no consensus, making the shutdown highly likely.
