Polymarket is launching a major infrastructure upgrade and a new native stablecoin over the next two to three weeks. The update includes a rebuilt central limit order book and a shift from USDC.e to a new token called Polymarket USD, backed 1:1 by USDC. This move aligns with improving U.S. regulatory clarity for prediction markets and signals a push toward more scalable, institutional-grade platforms.
Prediction market platform Polymarket is upgrading its core exchange infrastructure and introducing a new platform-native stablecoin. The update signals a shift toward more scalable, institutional-grade prediction markets.
The rollout is expected over the next two to three weeks and includes a rebuilt central limit order book, new smart contracts, and a collateral transition. The platform will migrate from USDC.e to a new token called Polymarket USD, which is backed 1:1 by USDC.
At the center of the upgrade is CLOB v2, a redesigned order book system intended to improve how trades are matched and executed. The new system introduces a simplified order structure, optimized matching logic, and improved fee handling.
It also adds support for advanced signing standards and on-chain attribution, allowing developers to track order flow. Polymarket said the upgrade will require a full reset of existing order books during migration, with a temporary maintenance window planned.
For most users, the collateral transition to Polymarket USD will be handled automatically through the platform interface. However, advanced users and API-based traders will need to manually wrap their USDC or USDC.e into the new token.
The introduction of a platform-native collateral token reflects a broader trend among crypto exchanges. They do this to streamline liquidity and improve trading efficiency by standardizing settlement assets.
Polymarket’s upgrade comes at a time when prediction markets are gaining clearer legal footing in the U.S. Recent court rulings have supported the view that event-based contracts fall under federal derivatives law.
It strengthens the position of platforms operating within regulated frameworks. At the same time, regulators continue to debate how these markets should be classified and overseen.
