Polymarket is restructuring how value moves across its platform, dropping the bridged version of USDC in favor of a native settlement layer it directly controls. The prediction market said it will migrate from USDC.e to a new collateral token, Polymarket USD, as part of a wider exchange upgrade rolling out over the next few weeks. The change goes beyond a token swap, reshaping how trades are collateralized, settled, and monitored across the system.
The platform confirmed that Polymarket USD will be backed 1:1 by USDC, maintaining dollar parity while removing reliance on bridged liquidity that previously connected ecosystems like Polygon and Ethereum. For users, the transition is expected to be mostly seamless through the interface. More advanced participants, including API traders, will need to manually wrap assets into the new token using a dedicated contract.
Polymarket Announces It Will Use Its Own Stablecoin

Bridged assets like USDC.e have played a key role in scaling activity across networks. They also introduce dependencies on cross-chain infrastructure, where risks can emerge from bridge design, liquidity fragmentation, or delayed settlement.
By introducing its own collateral token, Polymarket gains tighter control over how funds move within its markets. Settlement becomes internal instead of relying on external bridges. Fee collection, order matching, and collateral flows can now be coordinated within a single system.
Similar shifts are emerging across crypto markets as platforms reduce reliance on external liquidity sources. Platforms are moving away from fragmented liquidity sources and toward controlled settlement layers that reduce external points of failure.
The stablecoin migration is part of a larger infrastructure overhaul. Polymarket is deploying updated exchange contracts, often referred to as version 2, aimed at improving how orders are structured and executed.
Key changes include:
The upgrade also introduces a new SDK for developers, requiring builders and bot operators to update their systems. During the transition, existing order books will be cleared, with a short maintenance window expected.
The timing of this shift aligns with Polymarket’s efforts to expand within regulated US markets. After receiving approval from the Commodity Futures Trading Commission to operate an intermediated platform, the company has been adjusting its infrastructure to meet stricter operational expectations.
We’re thrilled to share that we've received CFTC approval for intermediation, paving the way for seamless access to polymarkets through registered brokers & financial institutions.

Controlling the settlement layer gives Polymarket direct visibility into fund flows, reduces reliance on external infrastructure, and standardizes how collateral moves across markets.
The move also introduces trade-offs. A platform-issued collateral token concentrates more control within a single system. Users remain indirectly exposed to USDC as the underlying reserve, while losing some flexibility that comes with widely used bridged assets across multiple ecosystems.
There is also a transition cost. Builders must update integrations, and liquidity tied to USDC.e will need to migrate. In the short term, this can create friction, especially for automated trading systems.
The shift points to a clear direction. As trading platforms scale, control over settlement is becoming as critical as liquidity itself.
