SoftBank is in talks to invest as much as $25bn into OpenAI, in a deal which would make it the ChatGPT maker’s biggest financial backer, as the pair partner on a massive new artificial intelligence infrastructure project.
The two companies announced last week they would lead a joint venture that would spend $100bn on Stargate — a sprawling data centre project touted by US President Donald Trump — with the figure rising to as much as $500bn over the next four years.
SoftBank is in talks to invest $15-25bn directly into OpenAI on top of its commitment of more than $15bn to Stargate, according to multiple people with direct knowledge of the negotiations.
