The French Socialist primary for the 2027 presidential candidate features five contenders—Raphaël Glucksmann as frontrunner, Olivier Faure, Ségolène Royal, Jérôme Guedj, and Emmanuel Maurel—with voting underway electronically from October 9-10. The two-round system requires an absolute majority for an outright first-round victory, yet recent debates have highlighted deep divisions over alliances, foreign policy, and strategy against other left-wing forces. Polling and analyst assessments indicate Glucksmann leads but falls well short of 50 percent amid vote fragmentation, while turnout among roughly 140,000 eligible participants has not produced a dominant consensus. These factors sustain trader expectations of a runoff between the top two on October 16-17.
