Nine House Democrats urge FTC to investigate prediction markets like Kalshi and Polymarket for alleged deceptive practices and regulatory evasion.
Nine House Democrats, led by Representatives Kevin Mullin (D-CA) and Gabe Vasquez (D-NM), have formally requested the Federal Trade Commission (FTC) investigate prediction market platforms such as Kalshi and Polymarket. The lawmakers accuse these platforms of employing deceptive practices, including advertising as gambling platforms while presenting themselves to regulators as financial tools.
In a letter dated June 3, the group outlined concerns that platforms may be evading state gambling regulations and misleading consumers about the rules and protections that apply. Specifically, the letter draws attention to the platforms’ use of language associated with sports gambling in public-facing materials, despite claiming to operate as investment-oriented exchanges with regulatory oversight.
“These prediction market companies are presenting themselves differently to regulators than they are to the public, and that kind of contradictory messaging can mislead consumers,” Mullin said in a statement. The lawmakers have asked the FTC to report by June 29 on whether it plans enforcement or investigative action.
Regulatory Challenges and Market Growth
This request comes at a time of heightened scrutiny for prediction markets, which allow users to trade contracts on the outcomes of future events, from political elections to economic indicators. Platforms like Kalshi and Polymarket have seen rapid growth, reportedly handling billions of dollars in event contracts annually. March 2026 marked a record high for transaction volumes, fueled by growing interest in geopolitical and political event contracts.
The regulatory landscape for these platforms is complex. The Commodity Futures Trading Commission (CFTC) asserts jurisdiction over event contracts under the Commodity Exchange Act, arguing that they are derivatives. However, state regulators have pushed back, labeling these contracts as gambling instruments subject to state-level oversight. A May 2026 court ruling temporarily barred Arizona from enforcing state gambling laws against Kalshi, signaling federal support for CFTC authority. Still, at least 11 states have taken enforcement actions against prediction market operators, underscoring the ongoing jurisdictional battle.
Key Risks Driving the Investigation
Beyond jurisdictional disputes, the calls for an FTC probe are driven by broader policy concerns. Allegations of insider trading and market manipulation have plagued the sector. In May 2026, Congress launched a separate investigation into Kalshi and Polymarket, scrutinizing their handling of insider trading incidents. Critics also argue that contracts tied to sensitive events, such as wars or assassinations, could pose national security risks.
The CFTC has attempted to address these risks through an Advanced Notice of Proposed Rulemaking issued in March 2026, seeking input on how to apply regulatory principles like market integrity and anti-manipulation to prediction markets. Academic research published earlier this year has also highlighted how wealthy actors can distort prediction market prices, further complicating regulatory oversight.
Potential Implications
If the FTC moves forward, this could significantly impact how prediction markets operate and market themselves. While the CFTC governs core trading activities, the FTC could step in to regulate marketing practices, disclosures, and platform design to ensure consumer protection. Such a move might force platforms to alter their business models or advertising strategies.
For traders, this regulatory uncertainty poses risks but also opportunities. Platforms could face higher compliance costs, potentially affecting liquidity and fees. On the other hand, clearer regulatory frameworks might attract more institutional participation, boosting market credibility.
With the FTC’s response expected by June 29, stakeholders should monitor developments closely. The outcome could shape the future of prediction markets, both as trading tools and as political flashpoints in the broader debate over crypto and fintech regulation.
