US startup grants and accelerators closing in December 2026
Short answer. 4 programs for founders in the United States close in December 2026: 3 grants and 1 accelerator. The first closes on 1 Dec 2026 (VentureWell Aspire Medtech 2027) and the last on 17 Dec 2026 (DOE Genesis Mission: Science and Energy with AI).
That is 4 of the 36 United States programs in my base that have a written closing date. The other 93 of the 129 that are not closed have no written date (12 rolling, 81 with no deadline found) and are not in this count. Every row below is read from the same list as open funding in the United States, so a program that closes or whose link dies leaves this page without anyone editing a line.
Closing in December 2026 (4)
Soonest first. Amount and closing date are the program's own words; a fact I did not find says not found. A date with a time is in UTC.

How current is this list?
Each row says the day its program's page was last read; the rows here were read 27 Sep to 10 Oct 2026. Open the program's page before you apply: dates and terms change.
What this list does not tell you
It does not say whether you are eligible: many rows are limited to a place, a field or who the founder is, and the program's page is the rule. It does not include programs with no written closing date, and it never converts or rounds an amount. It is information, not advice or an offer. A program is not listed once its deadline has passed or when its link was found dead on two checks in a row.
