Outgoing CME CEO Terrence Duffy stated that CME will sue the CFTC starting Thursday, opposing its approval for the launch of perpetual futures in the U.S. market. Previously, the CFTC approved prediction market platform Kalshi to offer Bitcoin perpetual futures at the end of May, and Kalshi later expanded to other cryptocurrencies. Duffy said that perpetual futures should essentially be considered swap products rather than regular futures under the Dodd-Frank Act. He also stated that CME has exclusive authorization from the relevant benchmark providers, so related products, whether they are perpetual contracts or not, should go through CME. (CNBC)
