Nasdaq 100: Nvidia and Chip Stocks Slide on AI Slowdown Talk

• Major AI leaders called for slower frontier AI development pace and delayed IPO plans, cooling market expectations that were priced for accelerated growth and aggressive spending on models and data centers
• Semiconductor stocks bore the brunt of selling with Nvidia, Intel, Marvell, and Micron down sharply in premarket; global chip suppliers including SK Hynix, Samsung, ASML, and Infineon also declined
• Oil above $100 due to Saudi pipeline shutdown adds inflation pressure ahead of the Fed meeting, with fed funds futures pricing an 86% chance of a rate hike

Market Summary: Nasdaq 100 Drops on AI Slowdown Concerns

Key Developments

The Nasdaq 100 fell sharply on September 14, 2026, driven by concerns about slowing AI development after industry leaders signaled a more cautious approach. Nasdaq futures declined 1.44% while Dow futures dropped 0.22% and S&P 500 futures fell 0.56%.

Major Catalyst

Anthropic CEO Dario Amodei called for a slower pace on frontier AI development, while OpenAI CEO Sam Altman endorsed a federal safety framework and dismissed the possibility of an IPO this year. Elon Musk echoed Amodei's concerns. These statements triggered widespread selling in AI-related stocks priced for accelerated growth.

Companies and Sectors Impacted

Nvidia faced significant pressure, with premarket trading indicating an opening around $213.12, below the swing bottom of $215.10 and approaching its 50-day moving average at $212.58. Other semiconductor stocks including Intel, Marvell, and Micron declined more sharply.

Internationally, SK Hynix and Samsung Electronics fell in South Korea, while ASML, Infineon, Siemens Energy, and Schneider Electric weakened in Europe. The Philadelphia Semiconductor Index ETF traded below its 50-day moving average at $531.52.

Market Implications

The selloff reflects traders repricing AI stocks that had been valued on assumptions of faster model development and continued hyperscaler spending. While inference demand remains strong, the slower development trajectory impacts near-term growth expectations.

Adding pressure, WTI crude rose above $100 following Saudi Arabia's pipeline shutdown, increasing inflation concerns ahead of the Fed meeting, with an 86% probability of a rate hike priced in.

Key technical levels to watch: Nasdaq-100 retracement zone at 29,060-28,690, with 200-day moving average at 27,793.
