The Commodity Futures Trading Commission has sued Gemini, the crypto exchange owned by Cameron and Tyler Winklevoss.

Bloomberg reports that the CFTC accused Gemini of "[misleading] it in answers to questions about a futures contract pegged to the price of bitcoin on Gemini’s digital asset trading platform."

"In a suit filed in Manhattan federal court Thursday, the CFTC claimed Gemini “made false and misleading statements” in meetings with commission staff from July to December 2017 about the operations of the Gemini Exchange and the Gemini Bitcoin Auction."

Cboe's cash-settled bitcoin futures utilized price data from Gemini's exchange when they launched in December 2017, as the firms announced at the time.

A copy of the complaint was not immediately available at press time. The CFTC, Gemini and Cboe did not immediately respond to requests for comment.
