Gemini’s Tyler and Cameron Winklevoss are at the center of the latest controversy in the crypto world, concerning the nomination of Brian Quintenz for chair of the U.S. Commodity Futures Trading Commission (CFTC).

The two billionaire Gemini co-founders pressed President Donald Trump to rethink Quintenz’s nomination, sources told Politico. The Senate Agriculture Committee then canceled a vote to advance Quintenz at the White House’s request.

The New York Post reported an uproar erupted after emails, obtained via a Freedom of Information Act (FOIA) request, were shared with the Post.

Quintenz’s incoming staff reportedly sought confidential CFTC information while he remained on the board of prediction market platform Kalshi, causing concern in both regulatory and crypto industry circles over his conflict of interest.

Tyler Winklevoss said that Quintenz’s regulatory approach was “not aligned with President Trump and the Administration’s stated goals” and argued his policy record and conflicts render him unfit to advance the administration’s deregulatory and pro-crypto agenda.
