Kalshi CEO Tarek Mansour navigates Washington as prediction markets face regulatory reckoning
The $22 billion prediction market exchange is juggling congressional scrutiny, state-level bans, and a federal turf war all at once
Kalshi CEO Tarek Mansour is learning this firsthand. The company he co-founded in 2018 with Luana Lopes Lara has grown into a $22 billion operation, making it the first federally regulated prediction market exchange in the US.
Congress comes knocking
On May 22, the House Committee on Oversight and Government Reform sent Kalshi a letter requesting detailed information about the company’s know-your-customer procedures and its anomaly detection measures, the internal systems designed to flag suspicious trading activity.
The catalyst: growing concerns about insider trading on the platform. Specifically, instances where politicians have been perceived to bet on their own electoral outcomes.
Mansour has responded by emphasizing Kalshi’s internal safeguards. The company has positioned itself as the compliance-first alternative to offshore competitors.
The federal-state tug of war
Minnesota became the first state to outright ban prediction markets in late May. The CFTC’s response was swift and aggressive: legal action to maintain exclusive federal jurisdiction over these platforms.
Wisconsin is another front in this fight. The CFTC has pursued legal action against the state as part of a broader effort to prevent a patchwork of conflicting state regulations from choking the industry.
Mansour has been vocal about framing prediction markets as fundamentally different from gambling. The argument goes like this: prediction markets price future events in a way that generates useful information for the public. Sports betting generates revenue for casinos.
New products, new risks
On June 1, Mansour appeared on CNBC to discuss Kalshi’s launch of the first regulated perpetual futures in the US. Perpetual futures are contracts that never expire, and are widely used in crypto markets by platforms like Bybit and dYdX.
Kalshi’s 2024 legal victory, which overturned previous CFTC restrictions on election-related betting, was the inflection point that sent trading volumes soaring.
Polymarket, Kalshi’s most prominent rival, operates largely outside the US regulatory perimeter. The sports leagues haven’t been quiet either. Major professional leagues have advocated for tighter regulations on prediction markets, viewing them as a potential threat to the integrity of their games.
