Nvidia’s Market Dominance and China Chip Sales Approval

Nvidia now accounts for 8% of the S&P 500, marking the highest share for any stock since 1981. Only Apple briefly crossed 7% in 2023. Even during the dot-com bubble, Microsoft and General Electric never exceeded 4%. IBM’s 1984 peak of 6% now trails Nvidia’s record weight, giving its daily price swings unprecedented influence over the index.

The concentration reflects how narrowly driven this bull market has become. No company—not even IBM in its 1980s heyday or tech giants during the 1999 frenzy—held such disproportionate sway. Meanwhile, the U.S. has greenlit Nvidia’s H20 AI chip exports to China after reversing an April ban. The chips were designed to comply with Biden-era restrictions, but shipments had stalled earlier this year. Nvidia warned the ban could cost $8 billion in quarterly revenue.

Approvals accelerated after CEO Jensen Huang’s WHITE House meeting with former President Trump. Critical details—license volume, eligible Chinese buyers, and shipment values—remain undisclosed. The move underscores how geopolitical tensions and AI demand converge at Nvidia’s crossroads.
