U.S. stock futures remained relatively stable on Wednesday following a decline in the major indexes the day before, fueled by renewed doubts regarding the sustainability of the artificial intelligence (AI) market surge and the impact of an ongoing government shutdown. On Tuesday, the S&P 500 and Nasdaq Composite experienced declines of 0.38% and 0.67%, respectively, retreating from their recent record levels, while the Dow Jones Industrial Average dipped by 0.2%. Oracle's shares decreased by 2.5% after the company reported disappointing cloud margins and incurred losses from renting Nvidia chips. The market's concerns about a potential rollback in the AI sector, reminiscent of the late-1990s dot-com bubble, further pressured stock prices. Concurrently, the persistent government shutdown affects market sentiment by delaying critical economic data and heightening the urgency for policymakers to negotiate a resolution.
