Jean-Luc Mélenchon leads trader pricing for second place in the April 2027 first round at 57 percent, reflecting consistent polling averages near 17-20 percent that place him ahead of fragmented centrist and center-right contenders. Multiple candidates including Édouard Philippe, David Lisnard, Bruno Retailleau, and Gabriel Attal split moderate support, while Raphaël Glucksmann and others compete on the center-left. Recent surveys through mid-November 2026 show Marine Le Pen well ahead at 33-36 percent, leaving the runoff qualifier contest tight among the rest. Further candidate declarations, primary outcomes on the right, or shifts in left-wing turnout could narrow or widen Mélenchon's edge before voting.
