US equity futures saw a decline on September 13, 2026, with the tech-heavy Nasdaq 100 Index futures falling 1.2% and S&P 500 futures also experiencing a drop. This downturn was attributed to a combination of renewed concerns over the pace of AI development and higher-than-anticipated US inflation figures. The inflation data particularly fueled speculation that the Federal Reserve might implement an interest rate hike on the upcoming Wednesday.
The decline in futures followed a positive performance on the previous Friday, where the underlying Nasdaq benchmark had gained 0.9%. The market reaction indicates investor caution regarding the AI sector's near-term outlook, despite strong underlying demand for computing infrastructure. Executives from major AI companies, including Anthropic, OpenAI, and SpaceX, had issued warnings about the risks associated with rapid AI model development, contributing to market jitters.
Simultaneously, oil prices advanced significantly. US West Texas Intermediate futures were indicated near $102.38 a barrel, and the international benchmark sat near $107.02. This surge in oil prices, partly triggered by the shutdown of a key pipeline, added to inflation concerns and reinforced expectations of a hawkish stance from the Federal Reserve, further impacting investor sentiment toward rate-sensitive stocks. The Dow Jones Industrial Average experienced its weakest week since March, falling about 1.6% due to these input costs.
