Polymarket eyes new L2

Polymarket has not publicly launched a new Layer 2 chain. What it has announced is a full trading-stack overhaul scheduled for April 28, 2026. (docs.polymarket.com) The company’s changelog says CLOB V2 will go live at about 11:00 UTC on April 28, with roughly one hour of downtime. It will ship new exchange contracts, a rewritten central limit order book backend, and a new collateral token called pUSD. (docs.polymarket.com 1) (docs.polymarket.com 2) Polymarket also says all open orders will be wiped during the cutover and that old client software will stop working after go-live. Traders and developers have been told to migrate to new V2 software packages before the switch. (docs.polymarket.com 1) (docs.polymarket.com 2) That matters because Polymarket’s trading system already splits jobs between offchain and onchain components. Orders are signed by users, matched in an offchain order book, and then settled onchain through exchange contracts on Polygon. (docs.polymarket.com) In plain English, Polymarket already controls much of the trading experience even without its own chain. The April 28 upgrade pushes more of that core machinery into software and contracts it operates directly, while settlement still remains on Polygon. (docs.polymarket.com 1) (docs.polymarket.com 2) The specific claim that Polymarket is building its own Layer 2 traces back to late 2025, when crypto outlets and social posts circulated a Discord message attributed to team member Mustafa saying an L2 was the firm’s “#1 priority.” Those reports did not include a launch date, technical design, or formal company announcement. (thedefiant.io) (www.cryptopolitan.com) The backdrop was a Polygon infrastructure incident on December 18, 2025. Polygon’s post-incident summary said the chain kept producing blocks, but some Bor nodes stalled or fell behind and some applications saw degraded performance or request failures. (forum.polygon.technology) Polymarket’s own current docs still describe trades as settling atomically on Polygon, and its bridge docs say deposits from multiple chains are automatically converted into pUSD on Polygon for trading. That is the strongest evidence that, as of April 26, 2026, the production venue remains there. (docs.polymarket.com) (docs.polymarket.com) So the cleaner read is narrower than the rumor: Polymarket is not yet presenting a live proprietary Layer 2, but it is taking tighter control of the pieces around execution, collateral, and developer infrastructure. The next hard milestone is April 28, when that rebuilt stack replaces the old one in production. (docs.polymarket.com) (docs.polymarket.com)
