Polymarket Protocol V2 introduces new position tokens and contracts for trading, position operations, and resolution. Follow the guide for your integration while retaining CTF support. Existing CTF holdings are not converted.

Rollout Timeline

New markets begin trading on Polymarket Protocol V2 in phases. Existing CTF markets keep their current contracts for trading, settlement, and redemption. All dates are in 2026, and times are Eastern Time (ET). Prepare your V2 integration before market creation: some markets are created 24 hours before the planned trading dates below. Later phases depend on successful trading and settlement, correct reward scoring, and sufficient liquidity in the preceding phase. No cutovers are scheduled for Thanksgiving on November 26. Thanksgiving week’s NFL and college football games remain on CTF.

What Changes

  • Market identifiers: Integrations select V2 position IDs or CTF token IDs using the market’s version.
  • Trading: V2 orders use ExchangeV3, signing domain version "3", and new approval targets. CLOB balance and allowance requests for V2 positions use CONDITIONAL-V2.
  • Position operations: V2 balances live in PositionManager. V2 split, merge, and redemption use Router, with updated calls and payout handling.

Migration Guides

For integrations already using pUSD and the CTFExchangeV2 order format, collateral, wallets, CLOB credentials, and endpoints stay the same.
