Direct answer: As of November 4, 2025, the U.S. federal government shutdown is tied for the longest on record at 35 days, with the longest shutdown previously occurring from December 22, 2018 to January 25, 2019 (35 days). If the shutdown continued past November 4, 2025, it would surpass that record; however, the latest widely reported status is that it has reached 35 days and is tied for the record.

Context and key points

• Current status: The shutdown began on October 1, 2025, and, by early November 2025, had reached 35 days, matching the 2018–2019 shutdown as the longest in U.S. history.

• Previous record: The 2018–2019 shutdown lasted 35 days, from December 22, 2018, to January 25, 2019, and is the reference point for the longest shutdown to date.

• Impacts often associated with prolonged shutdowns: many federal agencies operate with furloughs or reduced activity; essential services may be disrupted, and millions of Americans reliant on federal programs can face delays or uncertainty depending on the duration and resolutions pursued by Congress.
