Olivier Faure holds the strongest position for second place in the first round of the French social-democratic primary because trader pricing reflects expectations that Raphaël Glucksmann will finish first among the five validated candidates. Faure, as PS first secretary, has consolidated support from party structures and voters favoring broader left alliances, including openness toward La France insoumise. Ségolène Royal sits well behind at lower implied probability after her campaign attacks on Glucksmann and emphasis on an “ordre juste,” while Emmanuel Maurel, Jérôme Guedj, and the excluded Philippe Brun trail further. Recent developments include the primary’s online vote, initially scheduled for 9-10 October but extended to 11 October following a cyberattack, alongside televised debates that highlighted divisions over alliances, Ukraine policy, and Gaza. With roughly 140,000 registered voters and more than 100,000 ballots cast, the first-round outcome will determine whether a runoff occurs the following weekend.
