Polymarket’s upgrade won’t automatically move existing bets to new contracts
Summary
Polymarket’s Protocol V2 rollout will not automatically migrate existing Conditional Tokens Framework (CTF) bets. Legacy positions remain on the CTF ledger, while V2 positions use a separate PositionManager contract; users can move eligible positions through a distinct migration process after Polymarket registers the event. App users generally need only complete any approval prompts. Developers must support both systems, use the correct share identifiers and signing versions, and obtain separate permissions for V2 trading and Router operations. The tentative Nov. 2 changeover applies to newly created markets, not existing bets. Polymarket recommends testing purchases, sales and balances across both market versions.
