Polymarket Introduces pUSD to Take Control of Its Settlement Infrastructure

Key Highlights

• Polymarket has launched Polymarket USD (pUSD) as its new settlement token
• The token is backed 1:1 by USDC and replaces bridged USDC.e
• The move gives Polymarket direct control over its settlement layer
• A full exchange upgrade (CTF V2) accompanies the rollout
• The shift aims to reduce risk, improve efficiency, and support institutional growth

Polymarket Overhauls Its Core Infrastructure

Polymarket has unveiled a major upgrade to its trading infrastructure, introducing a new settlement token—Polymarket USD (pUSD)—as part of a broader effort to take full control of its platform’s financial plumbing.

The launch forms part of the platform’s CTF Exchange V2 upgrade, which includes rebuilt smart contracts, a redesigned order book, and improved execution systems.

At the centre of the update is pUSD, a platform-native collateral token that replaces the previously used USDC.e, a bridged version of USDC on the Polygon network. 

A Shift Away From Bridged Assets

The move away from USDC.e reflects a broader effort to reduce reliance on external infrastructure.

Bridged assets, while useful for cross-chain liquidity, introduce additional layers of risk—particularly if vulnerabilities emerge in the bridge itself. By issuing its own token and managing collateral internally, Polymarket removes that dependency and gains tighter control over settlement processes. 

The new pUSD token is fully backed 1:1 by USDC, ensuring that each unit can be redeemed for an equivalent amount of the underlying stablecoin. 

Taking Ownership of the Settlement Layer

With the introduction of pUSD, Polymarket is effectively internalising one of the most critical components of its platform: the settlement layer.

Previously, this layer relied on external tokens and bridging mechanisms. Now, Polymarket controls how value moves within its ecosystem—from deposits and trades to payouts and withdrawals.

This shift is designed to:

• Improve settlement speed
• Reduce operational complexity
• Enhance reliability during high trading volumes

Faster settlement is particularly important for prediction markets, where capital is frequently recycled between events and delays can limit trading efficiency. 

Built for Scale and Institutional Access

The infrastructure upgrade also introduces features aimed at attracting more advanced users.

The new system supports standards such as EIP-1271, enabling smart contract wallets and multi-signature accounts to interact directly with the platform. This lowers barriers for institutional participants that rely on more complex custody setups. 

At the same time, improvements to order processing and gas efficiency are expected to enhance performance for high-frequency traders and market makers.

A Response to Rapid Growth

Polymarket’s decision to rebuild its settlement layer comes amid rapid expansion.

The platform has recorded significant trading volumes in recent years, with billions of dollars flowing through markets tied to political events, sports, and macroeconomic outcomes. 

As activity scaled, limitations in the original infrastructure—particularly around settlement speed and reliance on bridged assets—became more apparent.

The new system is designed to address those constraints while preparing the platform for further growth.

Part of a Broader Industry Trend

Polymarket’s move reflects a wider shift across the crypto industry.

As platforms grow, many are choosing to build and control their own settlement layers rather than relying entirely on external stablecoins or infrastructure providers. This approach allows for greater customisation, improved efficiency, and tighter integration with platform-specific needs.

However, it also raises questions about how value and branding are distributed between infrastructure providers and the applications built on top of them. 

Outlook

The launch of Polymarket USD marks a significant step in the platform’s evolution from a fast-growing application to a more vertically integrated financial system.

By taking control of its settlement layer, Polymarket is positioning itself for greater scalability, improved reliability, and deeper institutional participation.

More broadly, the move highlights a key trend in crypto’s next phase: platforms are no longer just building on infrastructure—they are increasingly becoming the infrastructure themselves.
