Prediction Markets Face New CFTC Pressure as Banks and Crypto Firms Eye Expansion

Prediction markets received a direct warning from the CFTC's new enforcement chief on March 31. At NYU Law School, Director of Enforcement David Miller declared that insider trading laws fully apply to Kalshi and Polymarket — calling it a dangerous "myth" that these platforms operate outside the law. 

His remarks came one day after Paradigm was reported to be building an institutional trading terminal for the same space.

The context matters. Monthly trading volumes on prediction market contracts have crossed $20 billion, attracting Wall Street banks and crypto firms. 

Two insider trading cases on Kalshi — a politician betting on his own race and a MrBeast editor trading on advance video knowledge — handed the CFTC its opening. With prediction markets now Miller's top enforcement priority, the regulatory moment has arrived.

Key Takeaways

• CFTC Director of Enforcement David Miller confirmed on March 31 that Section 6(c)(1) and Rule 180.1 fully prohibit insider trading in prediction markets — identical to the standard applied in securities law.
• Paradigm is building a professional trading terminal for institutional market makers, as Kalshi's valuation hits $22 billion and Polymarket eyes a $20 billion raise.
• Two bipartisan Congressional bills introduced in late March 2026 aim to bar government officials and lawmakers from trading on nonpublic information on CFTC-regulated platforms.

The CFTC's Enforcement Playbook: No More Gray Zone

Miller's address was his first public appearance since joining the CFTC on March 2. He named five enforcement priorities, with insider trading in prediction markets at the top. The legal basis is Dodd-Frank: event contracts are swaps under the Commodity Exchange Act, putting Section 6(c)(1) and Rule 180.1 fully in play. 

He also invoked the "Eddie Murphy Rule," which bars trading on misappropriated government data — a direct signal to federal employees.

"Unfortunately, there is a myth in the mainstream media and social media that insider trading law doesn't apply in the prediction markets. That is wrong."
— David Miller, CFTC Director of Enforcement, March 31, 2026

Miller flagged injury contracts and contracts tied to a specific individual as especially high-risk for both manipulation and insider trading. He added that the Division is actively hiring, pushing back against reports of attrition within the enforcement ranks.

Kalshi's Two Cases That Triggered the Advisory

The advisory followed Kalshi's disclosure of two internal cases. In May 2025, a political candidate bet $200 on his own race, admitted it was improper, and received a $2,246 fine and five-year ban. 

In August 2025, MrBeast editor Artem Kaptur traded on advance video knowledge and profited $5,397. Kalshi imposed a $20,397 penalty and a two-year suspension. Miller cited the second case at NYU as his enforcement benchmark.

The CFTC's advisory was clear: Kalshi's internal handling does not limit the Commission's own authority to prosecute identical conduct. Kalshi also disclosed it ran 200 investigations and froze multiple accounts in the past year.

Paradigm's Terminal and Wall Street's Push Into Prediction Markets

Capital is still moving in despite the scrutiny. Paradigm — whose co-founder Matt Huang sits on Kalshi's board — is developing an institutional trading terminal led by partner Arjun Balaji. It is designed to sit on top of existing platforms, not replace them. The firm is also considering an internal market-making desk.

Kalshi raised at least $1 billion in a new round, pushing its valuation from $5 billion to $22 billion. Polymarket is reportedly in talks to raise at a $20 billion valuation. A new venture firm focused solely on prediction markets has launched, backed by the CEOs of both platforms.

Legislation Moves in Congress and the States

Congress moved in parallel. The Public Integrity in Financial Prediction Markets Act targets government officials trading on insider knowledge on CFTC-regulated platforms. The PREDICT Act, introduced the same week, focuses specifically on members of Congress. 

Both were bipartisan. The trigger: an anonymous trader earned more than $400,000 betting on the capture of Venezuelan President Nicolás Maduro before the news broke publicly.

State pressure also built. New York's AG warned consumers that prediction markets lack standard financial protections. California Governor Newsom signed an executive order blocking state officials from participating. 

Kalshi and Polymarket responded by banning candidates from trading on their own campaigns and athletes from betting on their own events.

Conclusion

Prediction markets expanded fast by outpacing formal oversight. That era is ending. Miller's NYU remarks were not a threat — they were a legal reality check long overdue. The CFTC is hiring, Congress has two active bills, and Paradigm is building compliance-grade infrastructure for institutions. 

Anyone trading on privileged information — editors, candidates, or government insiders — now faces genuine civil and criminal risk. The market has grown up. Regulation followed.
