With a market cap of $4 trillion the 5% move in NVDA shares led a $200 billion increase in market cap — double the $100 billion investment.
Nvidia, a chipmaker, signed a deal to invest as much as $100bn in OpenAI, an artificial-intelligence firm, to build data centres with a capacity of 10 gigawatts. Nvidia will reportedly receive equity in OpenAI in return. The firms said the deal would power advanced AI. More than 700m people use OpenAI each week.
