CME to sue CFTC over Kalshi Bitcoin perp as Polymarket backs Brazil 66.5%

World Cup Group C Winner: Brazil Odds Jump to 66.5% as CME Plans CFTC Lawsuit Over Kalshi’s Bitcoin Perpetual

CME’s CEO said the exchange will sue the CFTC over the agency’s approval of Kalshi’s Bitcoin perpetual contract, spotlighting how U.S. regulators may treat newer derivatives and event-style contracts. On Polymarket’s “World Cup Group C Winner” market, traders currently price Brazil as the clear favorite, with odds recently moving higher.

Key Takeaways

• Polymarket prices Brazil at 66.5% to win World Cup Group C, ahead of Morocco at 29.5%.
• Traders lifted Brazil to 66.5% from 60.5% even as broader attention on regulated “event contract” venues rose after CME said it will sue the CFTC over Kalshi’s Bitcoin perp approval.
• The contract is scheduled to resolve on 2026-06-27, with $1,098,152 matched so far.

CME said it will sue the Commodity Futures Trading Commission, arguing the regulator wrongly approved KalshiEX’s Bitcoin perpetual contract as a futures product. The CFTC approved Kalshi’s BTCPERP contract on May 29, a day after Kalshi submitted it under Regulation 40.3, and the product references spot Bitcoin and has no expiry date. The report said perpetual contracts can allow leverage as high as 50-to-1 and use automatic liquidation that can wipe out positions during sharp moves. CME’s complaint argues the product should have been classified as a swap, which would have subjected it to stricter Dodd-Frank rules. Kalshi has recorded more than $5 billion in perpetual volume since launch, and shares of CME, Cboe and ICE fell after the approval as investors saw a competitive threat.
