Crypto news: Terrence Duffy, the soon-to-step-down CEO of CME, said that CME will sue the CFTC starting Thursday to oppose its approval of the U.S. market launch of perpetual futures. Previously, at the end of May, the CFTC approved the prediction market platform Kalshi to offer Bitcoin perpetual futures, and later Kalshi expanded into other cryptocurrencies. Duffy said that under the Dodd-Frank Act, perpetual futures should essentially be treated as swap products rather than ordinary futures. He also said that CME holds exclusive authorization from the relevant benchmark provider, so the related products should go through CME regardless of whether they are perpetual contracts.
