The U.S. Commodity Futures Trading Commission (CFTC) has appointed former federal prosecutor David Miller as its new head of enforcement, a move that comes as the agency prepares for expanded oversight of cryptocurrency and prediction markets.
The regulator said Monday that Miller, most recently a partner at Greenberg Traurig, has joined the agency to lead its enforcement division. His appointment places an experienced trial lawyer — and former member of the securities and commodities fraud task force in Manhattan — at the helm of the CFTC’s top investigative unit.
Miller previously worked at the U.S. Attorney’s Office in Manhattan, where he handled complex financial crime cases. In private practice, he represented clients in high-profile digital asset matters, including individuals accused of wire fraud, money laundering and insider trading tied to cryptocurrency platforms.
His selection reflects a broader staffing shift under Chairman Michael Selig, who took office in late December and has begun rebuilding parts of the agency. The CFTC, which is typically led by a bipartisan five-member commission, has experienced significant turnover in recent years. Selig currently serves as the sole political appointee.
The agency is expected to take on increased responsibility in overseeing crypto markets, particularly as regulatory debates intensify over how digital assets and emerging financial instruments should be supervised.
In a statement, Miller said he looks forward to supporting the chairman’s goals of promoting innovation while safeguarding U.S. markets from fraud, abuse and manipulation.
Beyond his courtroom experience, Miller also served as a terrorism prosecutor earlier in his career and worked as a technical adviser to the television series “Billions.”
His appointment signals that the CFTC intends to reinforce its enforcement arm at a time when digital asset regulation and market integrity are drawing heightened attention in Washington.
