Join us for the 2026 Doomsday Clock Announcement

On January 27th, the Bulletin of the Atomic Scientists will reveal the 2026 Doomsday Clock time. The announcement will occur during a live, in-person news conference at 10:00 a.m. ET (1500 GMT) streamed via the Bulletin‘s YouTube channel. Sign up for email updates to get reminders about the announcement and receive the Bulletin’s twice-weekly newsletter featuring regular coverage of issues that impact the Doomsday Clock setting.

In 2025, the Doomsday Clock was set at 89 seconds to midnight, the closest to midnight ever in the Clock’s 78-year history. The Clock is set by the Bulletin’s Science and Security Board (SASB) which is a select group of globally recognized leaders with a specific focus on nuclear risk, climate change, and disruptive technologies. The SASB provides the Bulletin with objective external perspectives on trends and issues in these fields and connects the organization to outside experts. The decision is made in consultation with the Bulletin‘s Board of Sponsors which includes eight Nobel Laureates.
