Polymarket Rebuilds Trading ‘Plumbing’ With New Stablecoin & Faster Exchange Stack

In an announcement posted on X on Monday, Polymarket said it’s rolling out what it described as its biggest infrastructure change since the decentralized prediction market’s launch back in 2020. 

The changes include a rebuilt trading engine, updated smart contracts, and a new collateral token called Polymarket USD. 

Over the next two to three weeks, the event contract exchange will overhaul its core infrastructure to improve execution speed, lower gas costs, and create a cleaner technical foundation going forward.

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

In other words, Polymarket will replace the token users post as collateral with its own wrapper around USDC, while also upgrading the system that matches trades behind the scenes.

Most of the changes to the front end will be handled automatically, the company said. However, open orders will be canceled for a short time during the maintenance window, which will be announced at least a week in advance. 

What the Upgrade Actually Changes

From a technical perspective, Polymarket is launching CTF Exchange V2 and a new version of its central limit order book, or CLOB.

If you’re not familiar with the crypto space, these changes basically mean faster trade matching, lower transaction costs, and updated rails for bots, apps, and other tools that plug into the exchange.

The company also said the new stack will support EIP-1271 signatures, a change that should make it easier for smart contract wallets to interact with the platform.

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

TypeScript, Python, and Go clients are expected to be ready before release day, with migration docs and a full API changelog still to come.

Upgrade Follows a String of Infrastructure Deals

Polymarket’s April 6 announcement follows several moves by the company in early 2026 to strengthen the technical infrastructure behind its exchange. The company has spent the past few months building out its core technology through a series of acquisitions and major funding rounds.

• February 19: Polymarket acquired Dome, a Y Combinator-backed startup that specializes in unified API infrastructure, to streamline how third-party tools access market data.
• March 18: The company purchased Brahma, a DeFi infrastructure specialist, to improve wallet creation, cross-chain operations, and token redemptions.
• March 27: Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, completed a $600 million direct cash investment in Polymarket. This followed ICE’s $1 billion investment in late 2025.

As Polymarket integrates these specialized technologies and secures significant institutional backing, it’s increasingly positioning itself as more than a typical betting platform.

The new infrastructure gives Polymarket the core trading “plumbing” it needs to reduce its reliance on third-party providers, allowing it to create a more stable, scalable environment as it continues its CFTC-regulated re-entry into the United States market.
