President Donald Trump rejected calls to slow artificial-intelligence development, arguing that AI and data centers are major economic growth engines. The debate comes as infrastructure spending on computing and energy capacity supports growth, while the hoped-for productivity gains from wider business adoption remain less developed. Morgan Stanley chief U.S. economist Michael Gapen estimated AI-related spending has added an average 0.4 percentage point to annualized GDP growth since 2025. Analysts at Bank of America said AI networks remain fully utilized and rental rates for older chips are rising. Nvidia CEO Jensen Huang supported AI safety engineering and testing while disputing catastrophic forecasts, and Sen. Jon Ossoff raised concerns about the Trump family’s financial ties to AI-related investments. AI chip stocks fell nearly 6% as investors weighed whether a slowdown in frontier development could unsettle markets and tighten financing conditions for data-center projects.
