Microsoft is losing exclusive access to OpenAI's technology, clearing the way for the ChatGPT creator to sell its products across rival cloud platforms in a sweeping change to one of the artificial intelligence era's most consequential alliances.
The reworked tie-up, announced jointly by the companies on Monday, retains Microsoft as OpenAI's primary cloud partner with a license to the startup's intellectual property through 2032.
But the software giant will no longer share revenue for the OpenAI products it sells on its cloud. Revenue OpenAI must share with Microsoft through 2030 will now have a cap for the total amount and no longer be tied to the startup's technology milestones — including if it achieves artificial general intelligence, the point at which AI matches or surpasses human ability.
The change is meant to simplify a complex relationship between OpenAI and one of its biggest and earliest backers. Microsoft's early bet on OpenAI allowed the company to roll out AI across its products and powered sales growth at its Azure cloud-computing business, turning the company into one of the biggest players in the high-stakes race for the technology. But tensions have been rising between the companies as OpenAI strikes cloud deals with rival providers to secure more computing power and build out an enterprise business that can compete better with Anthropic ahead of a potential IPO. The Financial Times reported last month Microsoft was weighing legal action against Amazon and OpenAI over a $50 billion cloud deal that may breach its exclusive cloud tie-up.
In an internal memo reported by CNBC, OpenAI said that the Microsoft partnership had been foundational but had limited the startup's enterprise reach, adding that demand since OpenAI launched on Amazon's cloud had been staggering.
"The new deal with Microsoft was essential for OpenAI to be successful in the enterprise market," said Gil Luria, an analyst at D.A. Davidson & Co. "AWS and Google Cloud enterprise customers have been limited in their ability to integrate OpenAI's products because of the exclusive relationship and will now be more likely to consider OpenAI alongside Anthropic," he added.
Microsoft shares initially fell 1.3% on the news but were trading little changed by late morning trading.
Alphabet and Amazon did not immediately respond to Reuters' requests for comment. Alphabet shares were up 1.5%, while Amazon was down 0.5%.
Microsoft and OpenAI had also restructured their tie-up in October, removing major constraints on the startup's ability to raise capital and secure computing resources.
The software giant has in recent months been working to reduce its reliance on OpenAI by developing its own AI models and rolling out those developed by companies such as Anthropic in its products, including 365 Copilot for enterprises.
It has also said that it has been constrained on AI capacity, which has limited growth for its cloud business.
"From Microsoft's perspective, it does not need to build out all the data center needs for OpenAI, freeing up capital for Copilot and other cloud capacity," Barclays analysts said, calling the move a positive for both Microsoft and OpenAI. Ending the exclusivity pact may help Microsoft address antitrust scrutiny in the U.K., the U.S. and Europe over whether its OpenAI tie-up gives it an unfair advantage in the cloud and enterprise AI markets.
