Polymarket Launches Major Overhaul to Transition to Institutional Trading
Polymarket is rolling out its most significant update yet, transitioning from a retail-focused prediction market to a more sophisticated platform tailored for institutional traders. This transformation includes a complete redesign of its trading engine, the introduction of a new order book, and the launch of its own collateral token called Polymarket USD. These changes aim to enhance execution speed, reduce costs, and better serve professional traders, bots, and brokers—especially as U.S. compliance requirements become more stringent.
The upgrade is described by the company as its “biggest change to date,” involving new smart contracts, an updated trading system, and a stablecoin for collateral. This move comes shortly after Intercontinental Exchange (ICE) invested $600 million in Polymarket, part of a broader plan to invest up to $2 billion in the platform.
Enhanced Trading Engine for Professional Traders
At the core of this update is a completely rebuilt order book and matching engine. This system governs how buy and sell orders interact, and improvements here can significantly impact execution speed and price accuracy. According to Polymarket, the new design will allow trades to settle faster while reducing gas costs for users.
The new system also supports EIP-1271, an Ethereum standard that enables smart contract-based wallets, such as multisigs and automated trading systems, to sign transactions. This expands compatibility beyond traditional wallets, which is essential for professional trading desks that rely on bots, APIs, and multi-signature wallets.
However, the transition will require some adjustments. Polymarket plans to cancel all open orders during the migration, though traders will receive several days’ notice. This step is necessary to ensure that orders created under the old system do not conflict with the new matching engine.
Power users may feel the impact more than casual traders. Those running automated trading bots will need to update their software development kits to work with the new order structure. Builders using APIs will also need to adapt their integrations before trading resumes under the upgraded infrastructure.
Introducing Polymarket USD as a New Collateral Token
Alongside the trading overhaul, Polymarket is introducing a new stablecoin called Polymarket USD. This token will be used as collateral across the platform instead of the previously used bridged USDC.e on Polygon.
The shift positions Polymarket closer to the settlement standards expected by major financial institutions. With regulators increasingly scrutinizing crypto prediction markets, even jurisdictions like Portugal ordering a stop to political betting, standardized stablecoin infrastructure provides the platform with a stronger foundation as it scales toward mainstream finance.
Historically, Polymarket relied on USDC.e, a bridged version of Circle’s USDC stablecoin. While functional, bridged assets can add complexity and additional risks. By introducing its own token backed one-to-one with USDC, Polymarket aims to simplify settlement and improve liquidity management.
Users holding USDC or USDC.e will need to wrap their funds into Polymarket USD using a smart contract function. This process converts existing balances into the new collateral token so they can continue trading after the upgrade.
This shift has sparked speculation among users. Some believe the platform could generate additional revenue by managing collateral flows internally. Others think the token could allow Polymarket to introduce incentives or yield-related features for users who keep funds on the platform.
Navigating Regulatory Scrutiny and Institutional Growth
The timing of the upgrade comes as Polymarket continues to navigate regulatory scrutiny, particularly in the United States. Strengthening infrastructure, improving compliance readiness, and supporting institutional participants could help the platform operate more smoothly in stricter regulatory environments.
By rebuilding its trading engine and introducing a dedicated collateral token, Polymarket is shifting from a simple retail prediction site into a more professional trading venue. This evolution reflects the growing demand for institutional-grade tools in the decentralized finance space.
