Trump declassifies new UFO files by May 31?

This market will resolve to "Yes" if the Trump administration declassifies any files pertaining to extraterrestrial life and/or unexplained aerial phenomena which were not previously publicly available by May 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". For purposes of this market, the “Trump administration” includes the Executive Office of the President and all executive branch departments, agencies, and subordinate offices under presidential authority during the Trump presidency, including the Department of Defense and its components. Announcements of declassifications that are not implemented within this market's timeframe will not count. The primary resolution source for declassification will be official information from the government of the United States; however, a consensus of credible reporting will also be used.
