OpenAI’s wide-ranging partnership with Amazon, announced on Friday as part of a bigger series of funding agreements valuing the company at $730 billion before the investment, means the ChatGPT creator will soon have two of the three biggest cloud firms pitching its services. But can both Amazon and Microsoft get a big boost without encroaching on each other’s territory? Then there’s the impact on Nvidia, which is putting in $30 billion as part of an expanded chip deal. OpenAI is discussing raising additional funding in this round from financial investors such as United Arab Emirates investment fund MGX and others. That portion of the round is expected to total at least $10 billion and is expected to close by the end of March, a person with knowledge of the discussions said.
