Why this matters:
Marine Le Pen is assigned a 14% probability of winning the 2027 French presidential election, meaning betting markets view her as an underdog despite her National Rally party's recent electoral gains. This probability reflects legal and institutional constraints: Le Pen faces an ongoing conviction that could result in a five-year political ineligibility, which would bar her candidacy entirely. The key tension is that her party colleague Jordan Bardella (30% probability) emerges as the stronger contender, suggesting markets expect either Le Pen's disqualification or strategic party preference for a younger candidate without legal encumbrances. Upcoming judicial decisions on her eligibility, combined with National Rally internal positioning decisions expected over the next 12 months, will substantially shift these probabilities. The election itself occurs in April 2027.

Key factors:
- Le Pen's conviction status and appeals process—a formal ban would reduce her probability toward zero, while exoneration could push it substantially higher
- Relative viability of Jordan Bardella as National Rally nominee—if party leadership backs Bardella instead, Le Pen's path narrows considerably
- Performance of center-right Republicans (Édouard Philippe at 22%) and left-wing coalitions in intermediate legislative and regional contests between now and April 2027
- French voter turnout and coalition-building dynamics, which historically influence second-round runoff outcomes and frontrunner viability
- Policy or scandal developments that shift National Rally's electoral positioning or voter base composition

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
