Next French Presidential Election

Platform comparison

Market context

Polymarket prices this contract at **30% YES**, with traders using USDC on Polygon and conditional tokens to express a view on who wins the next French presidential election. The market is tied to the election result itself, not to polling headlines, and it resolves when the winner of the 2027 contest is determined, including a second round if needed.

That price has to be read against France’s two-round system and a crowded field. The first round is currently scheduled for 18 April 2027, with a runoff on 2 May if nobody clears 50% outright, and Emmanuel Macron is barred from another consecutive term[1][17]. Recent coverage says the race is already being shaped by fragmentation, with the far right still the most formidable force and the centre still lacking a clear heir[2][8][13]. Reuters reported in July that polls continued to show Marine Le Pen as a serious contender despite her conviction, while other polling has put Jordan Bardella well ahead in first-round scenarios and strong in likely run-offs[3][19].

For traders, the main catalysts are candidate selection, alliance-building, and any legal or eligibility developments. The National Rally has still not fully settled its candidacy question, and the centre-right, Macronist bloc, and left are all working through succession problems and possible primaries[18][11]. Municipal elections, which were described as the last nationwide test before 2027, can shift perceived momentum and influence who is treated as viable in the market[8][16].

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

UK Frequently Asked Questions

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
