This market will resolve to “Yes”, if either of the following conditions are met:

1.  The National Bureau of Economic Research (NBER) publicly announces that a recession has occurred in the United States, at any point in 2025, with the announcement made by December 31, 2025, 11:59 PM ET.

Note that advance estimates will be considered. For example, if upon release, the advance estimate for Q2 2025 was negative, and the Q1 2025's most recent, up-to-date estimate was also negative, this market would resolve to "Yes". If on December 31, 2025 the latest estimate for quarterly GDP in Q3 2025 was negative, this market will stay open until the Advance estimate of Q4 2025 is published, at which point it will resolve to "Yes" if Q4 2025 was negative or if the NBER declares a recession by then.

Note that advance estimates will be considered. For example, if upon release, the advance estimate for Q3 2025 was negative, and the Q2 2025's most recent, up-to-date estimate was also negative, this market would resolve to "Yes". If on December 31, 2026 the latest estimate for quarterly GDP in Q3 2025 was negative, this market will stay open until the Advance estimate of Q4 2026 is published, at which point it will resolve to "Yes" if Q4 2026 was negative or if the NBER declares a recession by then.

Accidents, radiological dispersal devices (bombs that spread radioactive material using conventional explosives such as "dirty bombs"), or actions by third parties will not count toward this market's resolution.

Tests not explicitly claimed by US may still qualify if a clear consensus of credible reporting attributes the nuclear detonation to US. For example, an unclaimed nuclear test analogous to the 1979 "Vela Incident" would count if credible reporting attributes it to the US.
