Polymarket Launches Polymarket USD, Taking Full Control of Its Settlement Layer

The changes, which went live this week alongside a maintenance window that wiped all existing order books, mark one of the most significant infrastructure shifts in the platform’s history.

A New Settlement Token to Cut Bridge Risk

The centerpiece of the upgrade is Polymarket USD, a new collateral token backed 1:1 by Circle’s $USDC, as reported in the post from their official X account. It replaces $USDC.e, a bridged version of $USDC that had been routed through the Polygon PoS bridge. The distinction matters for a practical reason: any vulnerability in that bridge carried the potential to affect platform solvency directly. By issuing its own wrapped token and managing the collateral layer internally, Polymarket removes that external dependency entirely. For most retail users, the transition requires nothing more than approving a one-time prompt on the frontend.

The new settlement token sits within the broader CTF Exchange V2 smart contract system, which also restructures how orders are processed on-chain. The updated “Order struct” reduces the data payload required for each settlement, which translates to lower gas costs and faster transaction throughput. The platform’s hybrid architecture – off-chain order matching through a Central Limit Order Book paired with non-custodial on-chain settlement – remains intact, but builder codes have been revised to improve order attribution across that two-layer system.

Institutional Access Gets Easier

One of the more consequential additions for the platform’s longer-term trajectory is native support for EIP-1271, a standard that allows multi-signature and smart contract wallets to authorize orders directly. Until now, institutional participants using setups like Safe multisigs faced friction because the platform required signatures from externally owned accounts. That barrier is now gone, which analysts expect to lower the entry threshold for professional trading desks that have been watching prediction markets from the sidelines.

In March 2026, Polymarket recorded $10 billion in monthly trading volume – a platform record – fueled in part by a wave of high-stakes geopolitical contracts. Earlier reports placed monthly volume figures even higher, above $20 billion, in the opening weeks of the year. Intercontinental Exchange, the operator of the New York Stock Exchange, invested $2 billion in the company, pushing its valuation past $20 billion. Polymarket is also rebuilding its U.S. footprint after registering with the CFTC through its acquisition of QCX, a move that enables it to operate regulated markets for American users again.

Controversy and New Market Rules

The platform has not been without controversy during this period of rapid growth. Earlier this year, Polymarket drew criticism from both sides of the political aisle in the U.S. for hosting markets tied to the fate of a missing American airman held in Iran. The backlash was severe enough that the company pulled more than 219 war-related markets and published revised Market Integrity Rules on March 23, which explicitly prohibit trading by individuals who can influence the outcomes of listed events or who possess material non-public information. Whether those rules will prove enforceable in practice remains an open question, given the pseudonymous nature of on-chain trading.

On the distribution side, Google Finance began embedding live Polymarket odds directly into its interface in late March, a decision that effectively positions the platform as a real-time sentiment layer for mainstream financial audiences rather than a niche crypto product. That integration, combined with Binance’s reported beta-testing of integrated prediction market features, suggests the competitive environment is narrowing fast. Binance’s potential entry into the space carries obvious weight given its user base, and Polymarket’s exchange upgrade can partly be read as an attempt to harden its technical infrastructure ahead of that pressure.

POLY Token Still Pending

What is notably absent from this release is the POLY governance token, which the company has confirmed is in development for use in platform governance and user incentives. It was not included in this upgrade, and no launch date has been announced.
