This market resolves YES if, at any point during Donald Trump’s current presidency, the United States tests or uses a nuclear weapon.

“Test” means any nuclear detonation — underground, atmospheric, or subcritical — officially conducted or authorized by the U.S. government for research, maintenance, or demonstration purposes.

“Use” means the detonation of a nuclear weapon in military action or combat.

The market resolves NO if Trump’s presidency ends without either event occurring.

Sources: Resolution will be based on official U.S. government statements (e.g. Department of Defense (“War”), Department of Energy, or the White House) or confirmation by major media outlets such as Reuters, AP, BBC, or The New York Times.
