Polymarket revamps matching engine with hybrid CLOB, smart‑wallet support and USDC‑backed Polymarket USD
Polymarket is overhauling its trading stack, rebuilding its core engine, introducing a hybrid central limit order book and launching a USDC‑backed stablecoin on Polygon [1][2].
Polymarket said it will rebuild its core matching engine and introduce a hybrid central limit order book to speed order matching and support smart‑contract wallets, calling the work its largest infrastructure upgrade since the platform's founding [1] [2] [3].
As part of the revamp, Polymarket will launch Polymarket USD, a USDC‑backed collateral token on Polygon that will serve as a native settlement currency aimed at lowering costs and making trading more institution‑friendly; reports say it will replace USDC.e as the platform's settlement token [1] [4] [5] [3].
The company frames the work as a full exchange upgrade designed to give it greater control over trading and market data as it prepares for a U.S. expansion; coverage describes Polymarket as a roughly $20 billion prediction market [6].
Polymarket plans to roll out the April 2026 upgrade that bundles the new trading stack and the Polymarket USD stablecoin as the core elements of the release [2] [1].
