US equity futures experienced a decline, and oil prices advanced on September 13, 2026. This market movement was primarily influenced by two key factors: renewed concerns regarding the speed of artificial intelligence development and higher-than-anticipated US inflation figures. These elements combined to strengthen expectations that the Federal Reserve might implement an interest rate increase later in the week.

The technology-heavy Nasdaq 100 Index futures saw a notable decline of 1.2% in early Asian trading, despite its underlying benchmark having gained 0.9% on the preceding Friday. Similarly, S&P 500 futures also registered a fall. This downward trend in futures indicates a cautious sentiment among investors heading into the new trading week.

Market observers suggest that semiconductor manufacturers and other companies linked to artificial intelligence are likely to be most affected by an initial selloff. However, many analysts anticipate that the long-term impact will be limited, as spending on computing infrastructure for AI is projected to remain robust. The comments from AI executives regarding slowing down technology development contributed to the short-term concerns.
