Kalshi CEO endorses bill banning insider trading on prediction markets
Quick Take
- Kalshi CEO Tarek Mansour wrote on LinkedIn that he supports the new bill from Rep. Ritchie Torres on banning insider trading on prediction markets.
- Mansour distanced Kalshi from “offshore, unregulated” prediction market platforms with alleged cases of insider trading.
- Earlier this month, one Polymarket account made $400,000 by betting that the Venezuelan President would be ousted by January, sparking insider trading concerns.
Tarek Mansour, CEO of Kalshi, expressed his support for U.S. Rep. Ritchie Torres' recent bill aiming to block insider trading on prediction market platforms.
"Kalshi is supportive of the bill Ritchie Torres is looking to introduce to affirm the ban on insider trading on prediction markets," Mansour wrote in a Wednesday post on LinkedIn. "Why? Because we already implemented it."
Earlier this month, Torres introduced the "Public Integrity in Financial Prediction Markets Act of 2026," which would ban federal elected officials, political appointees, and executive branch employees from making bets on prediction markets involving "government policy, government action or political outcome."
This came after one account on the decentralized prediction markets platform Polymarket wagered that Venezuelan President Nicolás Maduro would be ousted by the end of January, and reportedly profited $400,000 following his capture. This has fueled concerns about potential insider use of government information.
In his LinkedIn post, Mansour sought to distance Kalshi from other prediction market platforms facing insider-trading allegations, though he did not mention any names.
"This should be obvious, but some recent reporting has been conflating regulated prediction markets with unregulated, offshore prediction markets," Mansour wrote. "What non-American, unregulated platforms do has no relationship to what regulated, American platforms do."
Mansour said that Kalshi, as a federally regulated platform, adopts insider trading regulations from the New York Stock Exchange and Nasdaq, barring users from trading if they have access to non-public information on a market.
"However, it's important to emphasize that this American bill only applies to regulated American companies and not to unregulated, non-American companies, which is where the alleged issues are occurring," Mansour added.
Meanwhile, both Kalshi and Polymarket renewed their all-time high records for monthly volume in December — Kalshi reported $6.26 billion while Polymarket saw $2.28 billion, according to The Block's dashboard. Since March 2025, Kalshi has consistently widened its lead over Polymarket as the largest prediction market exchange by volume.
Several other major players in crypto and sports betting have joined the prediction markets arena, including Crypto.com, Gemini, and DraftKings.
