Congress probes CFTC on prediction markets, insider trading
US lawmakers sharply questioned Commodity Futures Trading Commission (CFTC) chair Michael Selig over market integrity and the rise of prediction markets, as concerns grow about insider trading and regulatory gaps.
During a House Agriculture Committee hearing on Thursday, 16 April 2026, Selig faced sustained scrutiny over how the agency polices event-based trading platforms, including those offering contracts on sports and geopolitical outcomes.
‘Zero tolerance’ stance on manipulation
Selig told lawmakers the regulator maintains a “zero tolerance” approach to fraud, manipulation and insider trading, warning that offenders would face enforcement action. However, he declined to provide specific figures when pressed on how many contracts the agency has rejected or how many investigations are currently underway. He said the CFTC “regularly” rejects self-certified contracts and suggested investigations could number in the “hundreds or thousands”.
The hearing comes amid heightened attention on the regulator following reports of unusual trading activity ahead of major policy announcements, including oil market bets placed shortly before geopolitical developments. Last month, prediction market platforms faced renewed scrutiny after allowing traders to wager on the timing of military strikes on Iran and even on the removal of the country’s supreme leader, Ayatollah Ali Khamenei. More than $500 million was staked on contracts tied to the timing of attacks, including bets that correctly predicted the date of the first strikes.
Similar controversies have surfaced before. In January, a mystery trader made a roughly $410,000 profit after betting on the ouster of Venezuelan president Nicolas Maduro. Even during the recent events, several accounts suspiciously made millions in just a day.
Blurred lines with sports betting
A central issue during the hearing was the similarity between prediction markets and traditional sports betting. Lawmakers questioned whether consumers can distinguish between the two, noting that contracts offered on event platforms can closely resemble sportsbook odds despite being regulated differently.

During the exchange, Representative Gabe Vasquez presented a side-by-side comparison of a prediction market contract and state-regulated sportsbook odds for a Colorado Rockies versus Houston Astros game. When asked to identify which was which, CFTC chair Michael Selig admitted he was not an expert. The exchange underscored growing concern in Washington that prediction markets may be operating in a regulatory grey area while competing with established betting operators.
Regulatory confusion and legal gaps
Committee members said the rapid growth of prediction markets has created uncertainty around the CFTC’s authority and the scope of existing laws. Some lawmakers argued that event contracts tied to sports and other outcomes resemble gambling products more than financial instruments, raising questions about whether they should fall under derivatives regulation.
Selig repeatedly pointed to an ongoing rulemaking process, which seeks public input on how such markets should be governed, but avoided giving direct answers on several contentious issues.
Concerns over tribal gaming rights
The debate also touched on the potential impact of prediction markets on tribal gaming. Lawmakers warned that allowing event-based contracts to operate under a different regulatory framework could undermine long-standing agreements between states and federally recognised tribes.
Some argued that platforms offering sports-related contracts risk bypassing established protections and revenue-sharing arrangements tied to tribal gaming compacts. Proposals such as geo-fencing, restricting access to certain areas, were raised as a possible safeguard, though no clear commitments were made.
Rising scrutiny on insider trading
The hearing comes as the CFTC faces increasing pressure over its oversight of trading activity more broadly. Recent reports have highlighted suspicious trades placed ahead of major policy decisions, including a large bet on falling oil prices shortly before geopolitical developments. Selig said the agency continues to investigate potential misconduct but declined to comment on specific cases or whether political actors had influenced trading activity.
The CFTC, which oversees futures, derivatives and certain event contracts, has found itself in the spotlight as new forms of trading blur the line between finance and gambling. With limited resources and an expanding remit, including potential oversight of digital assets, lawmakers signalled that clearer rules may be needed.
