PUSD Supply and Market Profile
Published 6/29/2026, 6:37:35 AM
Polymarket's native stablecoin, PUSD, has reached a circulating supply of approximately $510.22 million as of June 2026, crossing a critical threshold that has already triggered significant regulatory and Congressional scrutiny. This scale, combined with recent market integrity scandals, has moved the platform from a peripheral crypto project to a central focus of federal oversight.
PUSD Supply and Market Profile
PUSD serves as the primary collateral for Polymarket's prediction markets. While it is backed 1:1 by USDC, its rapid growth to over half a billion dollars has increased its visibility to regulators.

Current Congressional and Regulatory Scrutiny
Congressional scrutiny is no longer a hypothetical risk; it is an active reality. The $500M+ supply and high-profile betting activity have led to several formal investigations:
- House Oversight Probe: In May 2026, Rep. James Comer, Chairman of the House Committee on Oversight and Accountability, launched a formal probe into Polymarket. The committee requested records regarding user verification and the platform's ability to block prohibited jurisdictions [Source: https://oversight.house.gov/release/comer-probes-prediction-markets].
- CFTC Enforcement Investigation: On June 26, 2026, the Commodity Futures Trading Commission (CFTC) confirmed a new investigation into Polymarket following reports of market integrity violations [Source: https://www.politico.com/news/2026/06/26/cftc-polymarket-investigation].
- Subpoena Demands: Lawmakers, led by Rep. Chris Pappas, have called for subpoenas following reports of suspicious trading patterns, including a trader with a 93% success rate on military operation bets, raising concerns about insider trading of non-public government information [Source: https://pappas.house.gov/media/press-releases/pappas-leads-call-for-polymarket-subpoenas].
Key Drivers of Scrutiny
Beyond the raw supply of PUSD, specific scandals have intensified the focus from Washington:
- "Fake Bets" Scandal: A Wall Street Journal investigation alleged that Polymarket paid creators approximately $1.9 million to stage activity on the platform to inflate perceived volume [Source: https://www.wsj.com/articles/polymarket-fake-bets-scandal-2026].
- National Security Concerns: Reports indicate that nine accounts made over $2.4 million betting on military operations with a 98% win rate, leading to fears that the platform is being used to monetize sensitive intelligence [Note: not independently confirmed] [Source: https://pappas.house.gov/media/press-releases/pappas-leads-call-for-polymarket-subpoenas].
- Legislative Pressure: The Clarity Act (H.R.3633) was introduced to formalize federal oversight of prediction markets, specifically targeting the intersection of stablecoins and event-based wagers [Source: https://www.congress.gov/bill/119th-congress/house-bill/3633/text].
Conclusion
The $500M PUSD supply has already attracted significant Congressional scrutiny. While the 1:1 USDC backing mitigates some systemic financial risk, the platform's scale has made it a primary target for lawmakers concerned with market manipulation and national security. With active probes from both the House Oversight Committee and the CFTC, further hearings and potential restrictive legislation are highly probable throughout 2026.
