Nvidia has rebuilt the optimism around its stock, which was dented earlier this year when a breakthrough by China’s DeepSeek led to concerns about the durability of Nvidia’s dominant position in the global AI infrastructure market. That event wiped nearly $600bn from the company’s market value.

Nvidia shares rose to an all-time high on Wednesday, with the leader in artificial intelligence (AI) chips extending an advance that has cemented its position as one of the most valuable companies in the world.

Nvidia hit an all-time intraday high and headed for a record close as investors gain confidence that the chipmaker will power through China restrictions.
