Wall Street investors are increasingly weighing US midterm election risks against the booming AI trade as polls favor Democrats regaining control of at least one chamber of Congress. Strategists warn that a Democratic victory could pressure high-valuation AI stocks through intensified regulatory scrutiny, hearings, and potential legislative action. Brian Mulberry of Zacks Investment notes that strong Democratic performance could trigger increased AI safety hearings and market volatility. Wolfe Research strategist Tobin Marcus expects Democrats may form an "AI special committee" empowered to question industry executives and issue subpoenas, creating new headwinds for the sector.
