Polymarket Launches Stablecoin, Overhauls Trading System

Polymarket is rolling out its biggest platform upgrade to date, introducing a new stablecoin and rebuilding its trading system. 

The changes will take place over the next few weeks and aim to make the platform faster, simpler, and more reliable for users.

At the center of the update is a new collateral token called “Polymarket USD.” It will replace USDC.e and is backed 1:1 by USDC. 

For most users, the switch will happen automatically with a one-time approval. However, advanced users and bot traders will need to manually convert their funds.

At the same time, Polymarket is upgrading how trades are placed and matched. The platform is introducing a new order book system and updated smart contracts. 

These changes are designed to improve speed, reduce costs, and support more advanced trading activity.

As part of the transition, all existing order books will be cleared, and trading will pause briefly during a scheduled maintenance window. Polymarket said it will announce the exact timing in advance.

For everyday users, the impact will be minimal. The interface will handle most changes in the background. However, traders may notice smoother performance and quicker order execution after the upgrade.

Overall, the update signals a shift in how Polymarket operates. The platform is moving toward a more structured, exchange-like system built for higher trading volume and broader use.
