Polymarket introduced Protocol V2 on Monday as a rebuild of the market infrastructure that has supported its prediction markets since launch. The rollout began with a small set of canary markets already trading on V2, and the current trial is set to run through Oct. 30 with a tentative Nov. 2 switchover for new markets.

Key claims & sources

✓
Polymarket introduced Protocol V2 on Monday as a replacement for the architecture built on its 2019 Conditional Tokens Framework.
✓
Rajath Alex said the new version uses a single ERC-1155 position contract and pUSD as centralized collateral, and includes an oracle aggregator.
✓
A small set of canary markets began trading on Protocol V2 in production on Monday and are scheduled to keep running through Oct. 30.
✓
The trial for new markets is scheduled to run through Oct. 30, with a tentative Nov. 2 switchover.

What it means

Polymarket users and market participants are seeing a live test of the new setup already, because a small set of canary markets started trading on V2 in production on Monday. That means the switch is not only a design announcement; some activity is already running on the new infrastructure, and the planned timeline extends through Oct. 30.

In practice, Polymarket’s market plumbing is being rebuilt around a single ERC-1155 position contract, pUSD collateral, and an oracle aggregator, rather than the older structure built on the 2019 Conditional Tokens Framework. What remains the same is that prediction markets continue to trade, including the canary markets already live on V2, while the broader switchover is still scheduled later.
