Recent polling averages place Jean-Luc Mélenchon second in the first round at 17–19 percent, behind Marine Le Pen but ahead of Édouard Philippe and other centrists, reflecting sustained left-wing support and limited crossover from other blocs. Centrist fragmentation between Philippe and Gabriel Attal has eroded the moderate vote share, while Mélenchon’s recent rallies and program release have reinforced his position among younger and urban voters. With the first round set for April 2027, trader consensus assigns Mélenchon the highest probability for second place because no other candidate has demonstrated consistent momentum to close the gap in the fragmented field. Upcoming events such as further candidate announcements or shifts in economic sentiment could alter these probabilities before the vote.
