UBS warns that new U.S. restrictions on major AI model releases could trigger a semiconductor selloff while boosting software stocks. The policy shift creates a near-term headwind for AI chip leaders NVDA, AVGO, and MRVL whose revenues are tightly tied to accelerated AI buildout demand.
All three companies carry massive revenue growth momentum (NVDA +65.5% YoY, MRVL +42.1%) and have demonstrated that prior policy scares — including earlier chip export controls — were ultimately absorbed with minimal damage to underlying order books, suggesting the market may again look through a headline-level regulatory announcement.
NVDA trades on a premium multiple built entirely on uninterrupted AI capex acceleration, and UBS's explicit warning that semis are the direct loser from model release restrictions — combined with NVDA's 71.1% gross margin exposure to demand continuity — makes the stock vulnerable to a derating if any slowdown in frontier lab spending materializes.
