The United States government has initiated at least three previously undisclosed investigations into trading activities on the prediction market platform Polymarket. Documents obtained by WIRED through a Freedom of Information Act request reveal that the Commodity Futures Trading Commission (CFTC), the federal agency tasked with regulating prediction markets, has been actively pursuing potential instances of insider trading and market manipulation. These investigations, approved by CFTC Chairman Michael Selig, highlight a deepening concern within regulatory bodies about the integrity of these increasingly popular, yet largely untested, financial instruments.
Unveiling the Investigations: A Closer Look at CFTC Actions
The newly revealed investigations center on Polymarket contracts that tied to significant political and corporate events. The first, authorized in early May, focused on potential insider trading related to event contracts concerning pardons issued by former President Joseph Biden. This investigation granted the CFTC’s enforcement division broad powers, including the ability to take testimony, issue subpoenas, administer oaths, and compel the production of documents. While the specific trades under suspicion remain confidential, the timing of this order closely followed an NPR report detailing a Polymarket trader who amassed over $300,000 by betting on preemptive pardons for prominent critics of the former president, including former U.S. Representatives Liz Cheney and Adam Kinzinger, and Senator Adam Schiff. This trader’s uncanny accuracy in predicting these pardons, issued in the final days of the Biden administration, raised immediate questions about the potential for non-public information to influence market outcomes.
A second investigation, approved in late May, turned its attention to “Iran event contracts” on Polymarket. Although the specifics of this inquiry are also undisclosed, it emerged just two weeks after a 60 Minutes report exposed a network of Polymarket accounts that allegedly generated $2.4 million in profits from Iran-related trades with an exceptionally high win rate of 98 percent. The implication is that these substantial gains, particularly given the geopolitical sensitivities surrounding Iran, may have been driven by privileged information.
The third investigation, greenlit in July, targeted suspected insider trading on Polymarket contracts related to Google’s “2025 Year in Search Ranking.” According to an email exchange within the obtained documents, Paul Hayeck, acting director of the CFTC’s enforcement department, indicated that this probe would scrutinize “additional individuals who may have engaged in insider trading related to Google’s 2025 Year in Search Ranking.” Notably, Hayeck confirmed that the Southern District of New York (SDNY) was conducting a “parallel investigation” into related matters, suggesting a coordinated effort between different governmental bodies to address potential wrongdoing. This CFTC investigation is understood to be distinct from the ongoing case against Michele Spagnuolo, a Google engineer previously accused of insider trading in connection with Polymarket.
Regulatory Scrutiny and the Evolution of Prediction Markets
The CFTC’s increased focus on Polymarket comes at a time when prediction markets themselves are facing heightened regulatory scrutiny. These platforms, which allow users to bet on the outcome of future events, have experienced a surge in popularity, attracting significant capital and attention. However, their rapid growth has outpaced the development of clear regulatory frameworks, leading to concerns about their potential for misuse.
Joseph Konizeski, a former chief trial attorney in the CFTC’s division of enforcement, offered a critical perspective on the agency’s approach. He suggested that if these investigations are being initiated solely in response to media reports of potential violations of the Commodities Exchange Act, it could signify a fundamental weakness in the current regulatory structure. The CFTC has, in recent years, faced criticism for what some perceive as a lenient stance towards the prediction market and cryptocurrency industries, particularly during the second Trump era, according to reporting by The New York Times.
Polymarket, for its part, acknowledged the ongoing regulatory attention. Olivia Chalos, deputy chief legal officer at Polymarket, stated, "While we do not comment on specific investigations, we regularly refer matters to law enforcement and support ongoing investigations as part of our commitment to protecting the integrity of our markets." This statement indicates a willingness to cooperate with authorities, a stance that may be influenced by past regulatory actions.
A Pattern of Investigations: Polymarket and Its Rivals
The investigations into Polymarket are not isolated incidents. The CFTC has a history of examining potential insider trading on Kalshi, Polymarket’s primary competitor. Reports indicate that Kalshi has referred at least 32 cases of potential misconduct to the CFTC. A notable instance involved former U.S. Representative George Santos, who was fined $35,000 by the CFTC for his actions related to a Kalshi contract concerning his attendance at the 2026 State of the Union address. Kalshi also imposed a lifetime ban on Santos and an additional fine for market manipulation related to the same incident. These past actions demonstrate a consistent pattern of regulatory oversight being applied to the prediction market sector.
Furthermore, Polymarket itself has reportedly been under investigation by the CFTC. The company, which saw its primary U.S. platform banned in 2022, was subsequently permitted to launch a more narrowly focused, U.S.-regulated version in late 2025. This regulatory navigation coincided with a significant fundraising round led by 1789 Capital, a venture capital firm associated with Donald Trump Jr., which reportedly valued the company at $21 billion. This valuation underscores the significant financial stakes involved in the prediction market industry.
Implications and Future Outlook
The series of investigations into Polymarket highlights several critical implications for the future of prediction markets and their regulation. Firstly, it underscores the growing recognition by government agencies that these platforms, despite their novelty, are subject to existing financial regulations, particularly concerning insider trading and market manipulation. The ability of individuals to potentially profit from non-public information in these markets poses a direct threat to their integrity and investor confidence.
Secondly, the reliance on media reports as a catalyst for some investigations raises questions about the CFTC’s proactive enforcement capabilities. While media exposés can bring potential wrongdoing to light, a robust regulatory regime should ideally possess the mechanisms to detect and investigate such activities independently. The agency’s perceived “friendliness” towards the industry, as reported by The New York Times, may create an environment where proactive enforcement is crucial to maintain public trust.
Thirdly, the parallel investigations by the SDNY and the CFTC suggest a potential for increased inter-agency cooperation in addressing complex financial crimes that span different regulatory domains. This collaboration is essential for building comprehensive cases and ensuring that all avenues of potential misconduct are explored.
The involvement of high-profile individuals and events in the contracts under investigation – from presidential pardons to geopolitical events and major corporate announcements – demonstrates the broad societal relevance of these prediction markets. As these platforms continue to evolve and attract more participants and capital, the regulatory challenges are likely to intensify. The CFTC’s ongoing efforts, as revealed by these documents, signal a clear intention to apply a closer level of scrutiny to ensure that prediction markets operate within the bounds of the law and uphold principles of fair trading. The outcomes of these investigations, though currently undisclosed, will undoubtedly shape the regulatory landscape for prediction markets in the years to come. The market participants, platform operators, and regulatory bodies are all navigating uncharted territory, with the integrity and fairness of these innovative financial tools hanging in the balance. The public’s ability to place bets on future events, while seemingly innocuous, has now become a focal point for significant government oversight, reflecting the growing financial and societal impact of prediction markets.
