2027 French Presidential Election: who will be on the ballot?

According to the latest prediction market data for the query “2027 French Presidential Election: who will be on the ballot?”, traders have formed a strong consensus.

Currently, Jean-Luc Mélenchon is dominating the market with an overwhelming 91.7% chance of winning. Marine Le Pen follows in second place at 91.5%, while Nathalie Arthaud sits in third with 86%. The betting volume for this specific market has already reached $596K, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• Jean-Luc Mélenchon (91.7%): Currently commanding the highest probability, Jean-Luc Mélenchon is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 92¢, signaling a high degree of market conviction. This contract alone has generated $28.2K in volume.

🥈 Tier 2: The Primary Challengers

• Marine Le Pen (91.5%): Positioned as the most viable alternative, Marine Le Pen maintains a 91.5% chance of resolving true. Its “Buy Yes” shares currently trade at 92¢.
• Nathalie Arthaud (86%): Sitting in third place with a 86% probability, the market shows measured skepticism toward Nathalie Arthaud, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~0%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes Raphaël Glucksmann (82.5%), Fabien Roussel (81.5%), and David Lisnard (81%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like Édouard Philippe are still attracting notable interest.

The next French presidential election is currently expected to be held in April 2027. Prior to the election, the French Constitutional Council is expected to publish the official list of candidates to be included on the ballot for the first round of this election.

This market will resolve to “Yes” if the listed individual is included on the official candidate list for the first round of the 2027 French presidential election. Otherwise, this market will resolve to “No”.

If no such candidate list is published prior to the election, this market will resolve based on which candidates actually appear on the ballot when the election takes place. If no list is published and the specified election does not take place by June 30, 2027, 11:59 PM ET, this market will resolve to “No”.

The primary resolution source for this market will be the official candidate list published by the French Constitutional Council; however, a consensus of credible reporting may also be used.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome François Hollande currently trades at 20.5%, but our AI places its Fair Value at just 1%. This creates a large negative EV Gap of -19.5%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies Xavier Bertrand as the premium value opportunity on the board. While the market only assigns it a 6.7% trading probability, our AI’s Fair Value assessment sits at 23.9% — yielding an impressive +17.3% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include Gabriel Attal (EV Gap: +13.2%) and Clémentine Autain (EV Gap: +12.8%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
