The U.S. Commodity Futures Trading Commission is investigating Polymarket in a widening probe that now includes its marketing practices, social media activity, and the possible use of staged trades to attract users.
cftc expands polymarket probe
The inquiry follows pressure from lawmakers after allegations that paid online personalities promoted fabricated winning wagers without disclosure. Reports indicate the agency is examining whether replica websites and fake bet outcomes were used to mislead users, raising questions about compliance with federal advertising and derivatives laws.
A bipartisan letter from Senators Curtis and Schiff has urged the regulator to confirm whether these practices violate federal law, setting a July deadline for a response. The focus on promotional tactics signals stricter oversight could soon reshape how prediction platforms acquire users.
rapid growth draws scrutiny
The investigation comes as trading volume in prediction markets has surged. Weekly transactions recently reached $14.4 billion, up sharply from roughly $5–6 billion earlier this year, driven by major global events and rising mainstream attention.
Polymarket has posted steep growth since its U.S. relaunch, with daily trading volume climbing from $50 million in mid-May to more than $200 million by June 20. Its annualized revenue has already exceeded $1 billion.
Kalshi has also expanded rapidly, surpassing $10 billion in weekly trading volume for the first time. The firm reported annualized volume of $178 billion as of April, marking a dramatic year-on-year increase. Robinhood is gaining traction in the same segment, generating $123 million in quarterly revenue from event contracts tied to more than 12 billion trades.
jurisdiction battle intensifies
At the center of the issue is a growing conflict between federal and state authorities over how to classify prediction markets. The CFTC has asserted that event-based contracts fall under the Commodity Exchange Act and should be regulated as derivatives.
The agency recently sued Kentucky, arguing the state’s attempt to restrict platforms interferes with federal oversight. Kentucky, along with more than a dozen states including New York, has taken action claiming these platforms resemble unlicensed gambling operations.
At least sixteen states are now pursuing legislation or enforcement measures, raising the prospect of a fragmented regulatory landscape where access to certain contracts could vary by location.
legal challenges spread across the market
The dispute has broadened beyond states. The Chicago Mercantile Exchange has filed a lawsuit against the CFTC and its chair, challenging the approval of Kalshi’s Bitcoin-linked perpetual futures. The exchange argues the decision violated regulatory procedures and misclassified the products.
The contracts, approved on May 29, quickly drew more than $100 million in trading volume within their first day. A successful legal challenge could halt these instruments and force a reassessment of their role in regulated markets.
big tech and capital move in
Amid the regulatory uncertainty, capital continues to flow into the sector. Kalshi is reportedly seeking a new funding round that could value the company at $40 billion, following a previous raise that doubled its valuation to $22 billion.
Robinhood’s expansion into prediction products is accelerating, with revenue from the segment on track to rival its digital asset business. At the same time, Meta is exploring partnerships with Polymarket and Kalshi while developing its own prediction-focused platform, known internally as Arena.
outlook for traders
The combination of rapid growth and mounting legal pressure is setting the stage for significant changes across prediction markets. The CFTC’s actions are expected to clarify rules around marketing, contract classification, and fee structures.
For traders, the outcome could reshape access to platforms, alter liquidity conditions, and introduce volatility as federal and state authorities continue to contest control over the fast-growing sector.
