Microsoft Spent Over $100 Billion on OpenAI Partnership

Microsoft Corp. has spent more than $100 billion on its partnership with OpenAI, a sum that underscores the significance of the software maker’s role in the AI company’s growth.

That figure includes Microsoft’s original investments in OpenAI, as well as the costs of building infrastructure and hosting OpenAI’s computing, Microsoft deals executive Michael Wetter testified on Monday. It is cumulative through the current fiscal year which ends in June, he said.
