Taiwan Semiconductor Manufacturing reported a 57% rise in profit on strong demand for hardware to power AI systems.

Nvidia faces a significant revenue threat due to the latest U.S. export restrictions on artificial intelligence chips, designed to limit the global distribution of these coveted processors, analysts and investors said.

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.
