Polymarket rolls out Protocol V2 smart contract overhaul

Polymarket began rolling out its Protocol V2 smart contract system on Monday, October 5, 2026, according to Cointelegraph . The prediction market platform is testing the new infrastructure on a limited number of live markets through October 30, with a tentative target of November 2 for switching new markets over to V2. Rajath Alex, Polymarket’s head of protocol, announced the rollout in an X post. Polymarket’s existing system was built on Gnosis’s Conditional Tokens Framework from 2019, according to PANews. As market types and features multiplied, adapters and additional contracts had to be layered on top, driving up system complexity.
