UMA Optimistic Oracle, on-chain dispute processTrades are collateralized in pUSD, an ERC-20 token on Polygon backed 1:1 by USDC and enforced on-chain by smart contract (Polymarket migrated from USDC.e to pUSD in an April 2026 exchange upgrade); deposits and withdrawals of USDC carry no platform fee, though third-party on/off-ramps may charge their own. Taker orders pay a dynamic fee of roughly 0.04–0.07 depending on market category (geopolitics markets are fee-free), while maker (limit) orders are always fee-free and eligible for rebates; there is no fixed trade-size limit, only the depth of the order book. Markets resolve via the UMA Optimistic Oracle: an outcome is proposed on-chain, and if unchallenged it finalizes in about two hours; disputes escalate to a UMA token-holder vote.
For standard use of the main polymarket.com platform, no government ID, passport, or proof-of-address is required beyond connecting a wallet and passing an automated geo-IP eligibility check; Polymarket's terms reserve the right to request KYC/AML, sanctions-screening, or source-of-funds documentation at its discretion, and identity verification is required for certain newer beta products. Separately, Polymarket acquired the CFTC-licensed exchange and clearinghouse QCEX in 2025 and launched a distinct, CFTC-regulated entity, Polymarket US (operated by QCX LLC), in December 2025, which requires full KYC and serves eligible US traders as a separate regulated product. The main global platform, however, continues to geo-block the United States along with dozens of other jurisdictions as of this research; regulatory status for both the international site and Polymarket US has been changing rapidly through 2026 and should be reverified before relying on it.

Polymarket is the world's largest prediction market by trading volume, operating on the Polygon blockchain with USDC as the settlement currency. It works on a peer-to-peer binary share model: every market has Yes and No shares representing possible outcomes. You buy shares at a price between $0.01 and $0.99, reflecting the market's implied probability. If you hold the winning outcome when the market resolves, each share pays out $1.00. You do not bet against the house; you trade against other users. Markets cover politics, economics, sports, crypto, and geopolitics. There is no fiat deposit option directly; you deposit USDC to your Polygon wallet and trade from there.
Yes. Polymarket is the largest prediction market in the world and has operated since 2020. In November 2025 it received a CFTC Amended Order of Designation as a Designated Contract Market (DCM), the same regulatory category as CME Group through its subsidiary QCX LLC. Its security architecture is non-custodial: user funds are held in audited smart contracts on Polygon, not in Polymarket's bank accounts. This means that even in a company insolvency scenario, funds in smart contracts remain accessible. The platform received a CFTC settlement in January 2022 ($1.4 million) for operating an unregistered event contract exchange without proper registration. That regulatory history is worth knowing, though the company has since obtained full CFTC authorization.
Yes, for most US states, since December 2025. Polymarket returned to the US market after its subsidiary QCX LLC received CFTC DCM designation on November 25, 2025. The official Polymarket US app launched in May 2026. It is currently not available in Nevada, Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, New Jersey, and Ohio. California and New York are under regulatory review with restricted access. Users in available states must complete full KYC (government ID, SSN, and proof of residency) to participate.
For US users, SSN submission is required under CFTC regulations for Polymarket US as a federally registered DCM, Polymarket is legally obligated to verify the identity of US users, and SSN is standard for US financial services identity verification. KYC is processed through a licensed third-party identity verification provider, not stored directly by Polymarket. The platform uses session management and withdrawal address whitelisting as additional security layers. Verify you are on the official Polymarket. us domain before submitting any documents. This is an informational consult. See Polymarket's official documentation for your specific situation.
Polymarket charges taker fees (paid when you buy shares) that vary by market category and peak at the 50% probability mark. On the global platform: Crypto markets charge up to 1.80%, economics up to 1.50%, politics/finance/tech up to 1.00%, sports up to 0.75%, and geopolitics markets are currently fee-free. On Polymarket US (the CFTC-regulated version), a flat 0.30% taker fee applies regardless of category. There are no maker fees on either platform.
Yes. Winning shares resolve to $1.00 USDC each at market close. Resolution is determined by a designated resolution source or the Polymarket resolution team based on predefined criteria stated in each market's rules. Funds are held in audited Polygon smart contracts and credited to your wallet automatically upon resolution. Withdrawals go from your Polymarket USDC balance to any Polygon-compatible wallet address you specify. There is no minimum withdrawal amount beyond what covers the Polygon network gas fee, which is typically minimal.
Yes. You withdraw USDC from your Polymarket account to any Polygon-compatible wallet such as MetaMask, Coinbase Wallet, or a hardware wallet supporting Polygon. From there you can convert USDC to fiat through a centralized exchange or off-ramp service. Polymarket does not offer direct fiat withdrawals the withdrawal chain is Polymarket → USDC on Polygon → your wallet → exchange → bank. Withdrawal address whitelisting is available for added security. This content is for informational purposes only and does not constitute financial or investment advice.
