If a candidate wins the first round outright with a majority (or whatever threshold Paris requires to avoid a runoff), and no runoff occurs, the market for that winning candidate will resolve Yes and all other markets will resolve to No.

A candidate is "announced to qualify" when the official election authority of Paris certifies or announces qualification, OR when the Associated Press or at least two other Source Agencies report that Emmanuel Grégoire has qualified for the runoff, whichever occurs first. Official certification is not required for resolution.

This is determined at the time qualification is announced; subsequent withdrawals, disqualifications, or changes in eligibility do not affect whether the candidate qualified. If a candidate is announced to not qualify, the market will immediately resolve to No.
