À propos de cet opérateur
Polymarket est le plus grand marché de prédiction par volume d'échanges, réglant toutes les transactions en USDC sur la blockchain Polygon. Suite à un accord avec la CFTC en 2022, l'accès des utilisateurs américains est restreint sur la plateforme principale, mais Polymarket reste la destination mondiale de référence pour les contrats sur événements politiques, économiques et culturels. Les utilisateurs français peuvent y accéder via un portefeuille crypto.

FAQ — Polymarket
Can US users use Polymarket? +
US retail users are restricted on the main Polymarket platform following a 2022 CFTC settlement. Polymarket acquired QCEX, a CFTC-licensed exchange, in late 2025 and is rolling out a new, fully licensed US app via a waitlist. Full public access is estimated for Q3–Q4 2026. Non-US users can access the main platform freely via a crypto wallet.
Do I need a crypto wallet to use Polymarket? +
Yes. Polymarket settles all trades in USDC on the Polygon blockchain. You need a compatible crypto wallet (such as MetaMask, Coinbase Wallet, or Phantom) funded with USDC to trade. There is no fiat (bank) on-ramp directly on the platform; you need to acquire USDC via a crypto exchange first.
What fees does Polymarket charge? +
Polymarket charges approximately 2% on taker orders (market buys and sells). Limit orders that rest in the orderbook are charged a lower or zero maker fee. Fees are taken in USDC at the time of the transaction. There is no deposit or withdrawal fee on the blockchain side, though you will pay Polygon network gas fees (typically under $0.01 per transaction).
Is Polymarket safe? +
Polymarket uses on-chain settlement via UMA's optimistic oracle on Polygon. Funds are held in audited smart contracts rather than with a centralized custodian, which removes counterparty risk but introduces smart-contract risk. The platform has processed over $8 billion in lifetime volume without a systemic failure. The main risks are geo-restriction enforcement changes and the inherent complexity of self-custody.
What markets are available on Polymarket? +
Polymarket focuses on global politics (elections, geopolitics, international affairs), economics, science, and culture. It does not offer sports markets. Its orderbooks are the deepest in the world on high-profile political events: US presidential elections, geopolitical conflicts, and international political races regularly see millions of dollars in volume.
