Polymarket Launches Its Own Stablecoin, Reduces USDC Dependence

As a Polymarket user, I’m excited to hear about their big platform upgrade! They’re launching their own stablecoin, Polymarket USD, which is great news. This means they’ll be switching from using USDC.e to this new token, and it sounds like it’ll be fully backed by USDC, so it should be a pretty smooth transition.

The aims to improve trading efficiency and giving Polymarket more control over its liquidity.

Polymarket Introduces Its Own USD Stablecoin

Polymarket announced on Twitter that it’s switching from USDC.e to Polymarket USD as its primary collateral token. This change, along with improvements to its smart contracts, order books, and trading system, will roll out over the next two to three weeks.

The update will happen automatically for most users, requiring only a single confirmation. However, advanced users and those who use the platform’s API will need to convert their USDC or USDC.e to Polymarket USD themselves, using the platform’s designated contract.

We’ve listened to your feedback and are thrilled to announce a major upgrade to Polymarket! Over the next few weeks, we’ll be launching a completely rebuilt trading engine, improved smart contracts, and a new collateral token called Polymarket USD, which will replace USDC.e.

The platform announced the update will make it easier to match buyers and sellers, streamline the ordering process, and improve how fees are shared. Developers can use a new software toolkit to update their automated trading programs, but all current open orders will be cancelled.

Polymarket is making this change because it’s growing quickly, with over $22 billion traded in the first eleven months of 2025.

Users Question Trust and Adoption, Warn Risk to Circle

The announcement caused a significant response online. One user on X stated the change could seriously harm CRCL, because Polymarket currently pays Circle around 3.5% to 4% on deposits, and this move might encourage Polymarket to lessen its reliance on Circle.

If major platforms begin issuing their own stablecoins, it could give them greater control over transactions, allow them to profit from user deposits, and encourage continued platform usage.

While, not everyone is convinced the new stablecoin will succeed. 

Someone on X recently noted that while many organizations have attempted to create stablecoins, most haven’t been able to grow significantly. The commenter emphasized that building trust is crucial, and Polymarket’s reputation alone might not be sufficient for success.

Upgrade Requires Changes for Bots and Integrations

To help with the transition, Polymarket is launching a new SDK for its central limit order book. This update will manage the switch to the new system automatically, but developers will need to update to the newest version of the SDK.

Any automated systems or tools that create orders will need to be updated to work with the new order format. We’ll provide support for popular programming languages like TypeScript, Python, and Go, along with detailed instructions before the change goes live.

The platform will briefly pause for maintenance while we upgrade it, which will involve clearing all current open orders. Polymarket will let everyone know the specific timing of this at least a week beforehand.

If the launch is successful, the new stablecoin should make trading easier and the platform run more efficiently.
