The U.S. boom in building AI data centers is heightening supply-chain risks tied to reliance on Chinese power and optical communications equipment. If Washington tightens restrictions on national security grounds, shortages and higher costs could slow data center construction. Key components such as transformers, switchgear, batteries and optical transceivers depend heavily on China, while existing supply shortfalls for power equipment are already emerging, with limited near-term substitution capacity.

In August, U.S. stocks that had been weighed down by Wall Street’s bearish narratives rebounded sharply, CNBC reported. Jim Cramer said worries over AI threats, slower growth and worsening conditions were overturned by earnings and shifts in positioning. Moderna surged after reporting promising results for an experimental melanoma vaccine with Merck. Enterprise software names rebounded as a high-leverage hedge fund unwound bets. Other gainers included Gartner, Newmont, Paramount Skydance, Super Micro Computer, Sandisk and Coinbase.
