Will Jean Castex win the 2027 French presidential election?

Marine Le Pen leads trader pricing at 31% after a July 2026 appeals court ruling upheld her embezzlement conviction yet shortened her eligibility ban enough to clear a path for her 2027 candidacy, which she immediately confirmed while pursuing further appeals. This development has consolidated support for the National Rally amid voter fatigue with Macron-era policies, though persistent legal uncertainty caps her implied probability below recent first-round polling averages near 35%. Édouard Philippe trails at 25% as the leading center-right alternative, drawing from Horizons and fragments of the Macron coalition in a crowded field of more than 30 declared or potential contenders. Jean-Luc Mélenchon holds 13% on the left, where strategic divisions within the New Popular Front limit broader consolidation. The two-round system and record fragmentation keep the race tight, with outcomes sensitive to legal resolutions, candidate withdrawals, and turnout shifts before the April 2027 first round.
