How this market resolves

This market will resolve to "Yes" if the US Senate passes a motion to invoke cloture and end debate on any part of the legislative process, with such a cloture motion receiving Yea votes from fewer than three-fifths of the Senators by October 31, 2025, 11:59 PM ET. Otherwise, this market will resolve "No".

Confirmations are considered part of the Senate’s “advice and consent” function, not part of the Senate’s “legislative process,” and will therefore not count towards this market's resolution.

The resolution source for this market will be official information from the U.S. government.
