Nvidia faces a significant revenue threat due to the latest US export restrictions on artificial intelligence chips, designed to limit the global distribution of these coveted processors. The regulations, among the strongest yet from the Biden administration, limit AI chip exports to most countries except for a select group of close US allies.

Global data centers are filling up with GPUs and Nvidia has so far claimed an estimated 90% of that market share. Highly complex chips like GPUs are largely manufactured in Taiwan, but most of the companies that design them are based in the US and so their products are within the Department of Commerce's jurisdiction.

New rule threatens to squander America's hard-won technological advantage' says GPU supremo Nvidia has hit back at the outgoing Biden administration's AI chip tech export restrictions designed to tighten America's stranglehold on supply chains and maintain market dominance.
