Chip manufacturer to invest in return for stock after previous ‘circular’ $100bn deal dissolved earlier this month

Nvidia, the world’s most valuable company, is reportedly planning to invest $30bn (£22bn) in OpenAI’s next funding round, after a $100bn deal between the two dissolved earlier this month.

The maker of ChatGPT is expected to be valued at $730bn in the funding round, almost twice the valuation of Anthropic, one of its main rivals, which raised $30bn earlier this month.

Nvidia’s announcement of a $100bn investment in OpenAI last September drove the chipmaker’s stock to more than $5tn and led to fervent discussion about circular deals between the largest players in artificial intelligence.

The investment, which the chipmaker framed as a “letter of intent”, would have involved Nvidia giving OpenAI money to buy and deploy its chips for its AI infrastructure.
