Next French Presidential Election

Platform comparison

Market context

France’s next presidential election is scheduled for 18 April 2027, with a potential runoff on 2 May if no candidate secures over 50% in the first round. Incumbent Emmanuel Macron cannot stand due to the two-term constitutional limit, and the race is already shaping up as a transitional contest dominated by the National Rally.

Historically, French elections with an ineligible incumbent have produced high volatility in early trader sentiment, as seen in 2017 when Macron himself surged from obscurity to victory. The current 9% implied probability for a specific outcome (likely a non-RN candidate) reflects this uncertainty, but polls consistently show Jordan Bardella leading near 30%, with Édouard Philippe and Jean-Luc Mélenchon trailing. The divergence between Polymarket’s decimal odds and Kalshi’s implied probability models is notable here: Polymarket offers clearer liquidity for long-tail candidates, while Kalshi imposes stricter KYC and fee structures that may dampen speculative depth on fringe outcomes.

Traders must monitor the Paris Court of Appeal ruling on 7 July regarding Marine Le Pen’s embezzlement conviction, which could disqualify her and consolidate the National Rally behind Bardella. Recent updates from Le Monde confirm Gabriel Attal and Anasse Kazib as confirmed candidates, while Bernard Cazeneuve remains a likely contender. The 500-sponsorship requirement from elected officials continues to act as a barrier for outsiders, as noted in a 2 July Le Monde analysis. Watch for shifts in polling after Le Pen’s legal outcome, as both she and Bardella are projected to win the second round, though Bardella appears slightly more popular.
