Polymarket Upgrades Trading Infrastructure and Exchange Stack with New Stablecoin

(AsiaGameHub) –   In a Monday announcement shared on X, Polymarket stated it is rolling out what it describes as the largest infrastructure update since the decentralized prediction market first launched in 2020. 

The updates include a reconstructed trading engine, revised smart contracts, and a new collateral token named Polymarket USD. 

Over the next two to three weeks, the event contract exchange will revamp its core infrastructure to boost execution speed, reduce gas costs, and build a more streamlined technical foundation for future development.

The most noticeable change for the platform’s regular users will be the transition from USDC.e to Polymarket USD, which the company confirms is backed 1:1 by USDC. 

Put simply, Polymarket will replace the token users submit as collateral with its own USDC wrapper, while also upgrading the behind-the-scenes trade matching system.

Most front-end adjustments will be processed automatically, the company noted. However, open orders will be canceled for a short window during the maintenance period, which will be announced at least one week in advance. 

What the Upgrade Actually Entails

From a technical standpoint, Polymarket is launching CTF Exchange V2 and an updated iteration of its central limit order book, or CLOB.

For those unfamiliar with the crypto space, these changes essentially translate to faster trade matching, lower transaction fees, and updated infrastructure for bots, apps, and other tools that connect to the exchange.

The company also noted the new tech stack will support EIP-1271 signatures, a change that is expected to simplify interactions between smart contract wallets and the platform.

The upgrades extend beyond the retail trading experience. In an X post explaining the update, Polymarket Developers stated API traders, bot operators, and other integrators will need to update their software development kits and re-sign orders using the new system structure.

TypeScript, Python, and Go clients are expected to be available ahead of launch day, while migration documentation and a full API changelog will be released at a later date.

Upgrade Follows a Series of Infrastructure-Related Deals

Polymarket’s April 6 announcement comes on the heels of several moves the company made in early 2026 to strengthen the technical infrastructure supporting its exchange. The firm has spent the past few months building out its core technology via a series of acquisitions and major funding rounds.

• February 19: Polymarket purchased Dome, a Y Combinator-backed startup focused on unified API infrastructure, to simplify market data access for third-party tools.
• March 18: The company acquired Brahma, a DeFi infrastructure specialist, to enhance wallet creation, cross-chain operations, and token redemption processes.
• March 27: Intercontinental Exchange (ICE), the parent entity of the New York Stock Exchange, finalized a $600 million direct cash investment in Polymarket. This followed ICE’s $1 billion investment in the platform in late 2025.

As Polymarket integrates these specialized technologies and secures substantial institutional backing, it is increasingly positioning itself as far more than a standard betting platform.

The new infrastructure provides Polymarket with the core trading “plumbing” it needs to reduce its dependence on third-party providers, enabling it to build a more stable, scalable environment as it continues its CFTC-regulated re-entry into the U.S. market.
