NVIDIA shares fell 1.8% in pre-market trading on Thursday, alongside AMD and Micron, as Wall Street focused on whether customers can afford the cost of expanding AI infrastructure. Rising financing costs have added to concerns about the sustainability of the boom.

Financial pressure at CoreWeave, a key NVIDIA customer, has become a warning sign for investors. The company's bond yields have reportedly neared distressed levels, signaling financing challenges.

Investors worry that high borrowing costs could threaten future data-center projects despite strong current demand for AI chips. That could also put future orders for NVIDIA products at risk.
