Marine Le Pen leads the 2027 French presidential race in trader pricing due to consistent first-round polling leads for the Rassemblement National candidate at 35-37% in recent surveys, reflecting sustained support amid France's polarized electorate and the end of Emmanuel Macron's term. Édouard Philippe follows as the strongest center-right option, though recent Harris Interactive data shows him trailing or close to Jean-Luc Mélenchon in fragmented fields. Mélenchon's surge to 18-19% has boosted his runoff qualification odds across tested scenarios, driven by strong youth backing and left dynamics. A weak economy and hollowed center have favored hardline contenders, with Le Pen favored in most head-to-head polls but facing historical runoff challenges for the far right; the first round is scheduled for April 2027.
