Will anyone win France’s presidential election in the first round?

Kalshi — primary rule

If any candidate receives the required threshold of votes to be declared the winner after the first round of voting in the next French presidential election, eliminating the need for any subsequent rounds, runoffs, or instant-runoff tabulations, then the market resolves to Yes.

Polymarket — resolution criteria

Presidential elections are scheduled to be held in France on April 18, 2027, with a second round on May 2, 2027. A second round will be held if no candidate secures a majority of the valid votes in the first round. This market will resolve to "Yes" if any candidate wins this election outright in the first round. Otherwise, this market will resolve to "No". If the result of the first round of this election isn't known by May 31, 2027, 11:59 PM ET, the market will resolve to "No". This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the French government, specifically the Constitutional Council (Conseil constitutionnel) (https://www.conseil-constitutionnel.fr/).
