A Democratic majority in either chamber of Congress following the U.S. midterm elections would grant subpoena power and expanded oversight authority, potentially subjecting crypto firms, prediction markets, and Wall Street banks to intensified scrutiny. While such a shift may not halt the Trump administration’s deregulatory agenda, it would enable lawmakers to compel testimony from government officials and corporate executives through larger investigative teams. Democrats have pledged to examine business ties between the Trump family and the crypto industry for potential conflicts of interest, alongside broader reviews of bank regulation, AI financing, and consumer protection. Representative Sean Casten could assume greater influence over crypto policy if Democrats regain control of the House Financial Services Committee, having previously opposed the industry-backed CLARITY Act. Analysts warn that congressional investigations could impose significant legal costs, management strain, and reputational risks on targeted companies.
