Anything but a YEA vote will resolve that Senator to No. For example, not voting (such as by being completely absent from the room) or voting Present will count as a No. If a Senator changes their vote before the vote is finalized, the final vote will be what determines this market. For example, if they first vote NAY, then change it to YEA, and YEA is the final recorded vote, the market for that Senator will resolve to YES.
Should such a vote result in the rejection of the Nominee via a procedure that does not result in the recording of a tally of votes, or should a withdrawal of the nominee's nomination be formally communicated to the United States Senate, this market shall resolve to No. Should a vote result in the confirmation of the Nominee via a procedure that does not result in the recording of a tally
of votes, this market shall resolve to Yes. Should more than one Senate confirmation vote on the confirmation of the Nominee to the Office be held, the outcome of the first such vote will be used to resolve this market. If the nominee is withdrawn (or intent to nominate a nominee is withdrawn by the President or President-elect), then the market will resolve to No.
