Polymarket’s U.S. Reentry: Trust, Compliance, and the Battle for Prediction Market Legitimacy
The platform’s reentry hinges on differentiating its U.S. arm from its international counterpart, which faced scrutiny over ethical and legal issues.
Architectural Divergence: U.S. vs. International Platforms
Polymarket U.S. operates under Commodity Futures Trading Commission (CFTC) oversight, utilizing a centralized structure regulated by the Commodity Futures Trading Commission and funded with traditional U.S. dollars, while Polymarket International is built on blockchain technology and requires users to trade with cryptocurrency. This separation is regulatory and technical.
“Trust is the product we are building here,” said Dan Lee, head of U.S. operations at Polymarket.
The Compliance Overhaul: Hires and Surveillance
Polymarket’s reentry strategy includes hiring a slate of compliance, surveillance and regulatory specialists in recent weeks, including Megan McGrath from Robinhood as its new chief compliance officer. These hires signal a shift from the “freewheeling” ethos of its offshore days. The company has also hired former Department of Justice and FBI officials as the platform’s head of enforcement and new surveillance head.

Marketing Controversies and Trust Gaps
Despite its compliance efforts, Polymarket faces backlash over marketing practices.
Market Positioning: Kalshi’s Dominance and Regulatory Tailwinds
Polymarket competes with Kalshi. The trading volume across the platforms for Polymarket and rival Kalshi is now $26.6 billion, according to blockchain analytics firm Dune. About two-thirds of that activity is on Kalshi. Polymarket has signed partnership deals with major sports teams and Major League Baseball, as well as news organizations ranging from CNBC to CNN.
The Trump Administration has been generally supportive of prediction markets. The CFTC has sued states to argue that federal law should preempt any regulations that state politicians have wanted to place on the prediction market industry.
The Road Ahead: Trust as a Product
Polymarket’s survival depends on proving that Polymarket U.S. can be a trusted prediction market platform. This requires not just technical compliance but cultural change.
