Marine Le Pen leads trader pricing for the 2027 French presidential election at 45.5% due to her consistent first-round polling lead of 31-36% across recent surveys from Ifop, Harris Interactive, and Ipsos, reflecting Rassemblement National consolidation amid economic pressures and center fragmentation as Emmanuel Macron's term concludes. Édouard Philippe follows at 18.5% as the strongest center-right option in scenarios where he consolidates moderate support ahead of Gabriel Attal, while Jean-Luc Mélenchon's 12.5% reflects far-left momentum and youth backing that positions him for a potential runoff in multiple tested lineups. David Lisnard and François Hollande trail further behind as niche right and socialist contenders. These implied probabilities align with polling averages showing Le Pen advancing comfortably to a second round against either Philippe or Mélenchon, with the April 2027 first-round timeline and runoff dynamics shaping current market positioning.
