Polymarket launches stablecoin as Circle faces scrutiny over Drift hack response

Prediction market platform Polymarket has unveiled its own stablecoin, ‘Polymarket USD,’ as it prepares a near-term overhaul of its trading and settlement infrastructure—an internal shift that lands as stablecoin issuer Circle faces renewed scrutiny over its response time during a major exploit tied to Solana-based decentralized exchange Drift. Together, the two developments are refocusing attention on ‘trust’ and ‘execution risk’ in stablecoin plumbing, particularly when real-time settlement collides with compliance obligations. Polymarket said it plans to upgrade its broader transaction stack over the next two to three weeks following an April 6 announcement. As part of that transition, the platform will move away from the bridged token USDC.e and introduce Polymarket USD as a new collateral asset inside the platform. The token is designed to be 1:1 backed by USD Coin (USDC), with an automatic wrapping feature intended to make conversion seamless for most users. Polymarket noted, however, that certain participants—such as API-based traders—may need to complete a separate wrapping process to ensure compatibility with the upgraded rails. The move is being read as more than a simple technical migration. Some market participants have speculated Polymarket could eventually share revenue or offer yield-like incentives to holders of the new stablecoin, though no such program has been confirmed. Observers say the platform’s offshore footprint—outside direct U.S. jurisdiction—could provide additional flexibility relative to fully U.S.-domiciled issuers, even as global regulators increasingly scrutinize stablecoin models that blur the line between payments and return-bearing instruments. At the same time, Circle is being criticized for what some on-chain analysts describe as delayed action during a hack involving Drift that allegedly totaled about $285 million. Blockchain investigator ZachXBT said a significant portion of the stolen funds were denominated in USDC and that the attacker moved assets using Circle’s Cross-Chain Transfer Protocol (CCTP) without an immediate freeze being initiated. According to the account, the transfers continued for roughly six hours—including during U.S. business hours—raising questions about Circle’s operational readiness when illicit flows occur at high velocity across chains. ZachXBT also claimed that since 2022 there have been more than 15 instances in which Circle’s response to illicit funds was insufficient, totaling approximately $420 million. Circle has previously explored anti-fraud tooling, including research into refund-oriented protocols, but the latest dispute underscores how market confidence can hinge not only on reserves and attestations, but also on ‘incident response’ and the practical ability to intervene quickly when required. The controversy arrives amid intensifying competition across the stablecoin sector. Circle is preparing to launch ‘cirBTC,’ an institution-focused wrapped Bitcoin product, with initial plans centered on Ethereum (ETH) and its own payments network before expanding to additional chains. Rival issuer Tether, meanwhile, is reportedly pursuing fundraising aimed at reinforcing its market dominance, with aspirations that imply a significantly higher corporate valuation. Stablecoins are also increasingly entangled with geopolitical finance. Reports cited by local media suggest some tanker transit fees through the Strait of Hormuz are being paid in Chinese yuan or stablecoins, reflecting the growing role of digital dollars and dollar-like instruments in cross-border settlement. Separately, Russia is said to be expanding influence in parts of Africa through a ruble-linked stablecoin, A7A5—another illustration of how tokenized fiat can be leveraged in regions where sanctions, capital controls, or restricted access to correspondent banking constrain traditional rails. Polymarket’s introduction of Polymarket USD and the criticism surrounding Circle’s Drift-related response are, in different ways, reminders that stablecoins now sit at the intersection of payments infrastructure, market structure, and geopolitical frictions. For investors and institutions tracking the space, the next phase is likely to be shaped by which issuers and platforms can demonstrate resilient ‘compliance execution,’ reliable technical settlement, and credible real-world utility under growing regulatory pressure.
