Brian Quintenz joins prediction markets coalition

The Coalition for Prediction Markets announced Wednesday that Brian Quintenz has joined the industry group as a senior adviser. The coalition represents firms that run trading venues for event-based contracts and seeks clearer federal rules for prediction markets.

Members of the coalition include Kalshi, Crypto.com, Coinbase, Robinhood and Underdog. The group is led by Sean Patrick Maloney. Quintenz joins former House Financial Services Committee Chairman Patrick McHenry on the coalition’s list of senior advisers.

Quintenz served as a Republican commissioner at the Commodity Futures Trading Commission. He later worked as global head of policy at a16z crypto and has served on Kalshi’s advisory board.

President Trump nominated Quintenz in February 2025 to serve as CFTC chairman. Lawmakers questioned his ties to the prediction market and crypto industries. Quintenz pledged to resign from Kalshi and to recuse himself from matters involving the company if confirmed. The White House withdrew his nomination in September 2025 after considering alternative candidates.

Quintenz wrote that “Good regulation advantages strong innovation — and that doesn’t have to be specific to one firm,” and described the coalition as bringing together firms that want to “play by the rules” and ensure rules are calibrated to the markets they list.

Quintenz also released private messages he said were exchanged with Tyler Winklevoss, alleging the Winklevoss brothers sought assurances he would revisit a prior CFTC settlement with Gemini if confirmed as chair. The brothers denied lobbying against his confirmation and disputed his account.

Advocates for prediction market platforms have urged federal clarity, saying inconsistent state rules and enforcement actions have created uncertainty for operators that allow trading on event outcomes. The coalition has been engaging federal lawmakers and state regulators as it seeks a regulatory framework that would place certain event contracts under federal oversight.

The coalition said Quintenz will advise on regulatory engagement and policy strategy as it pursues legislative and administrative pathways to address legal uncertainty for prediction markets.
