Microsoft eyes Inception takeover

Microsoft is exploring AI startup acquisitions as it loosens the shape of its relationship with OpenAI and looks for additional model technology for Azure. Reuters reported on May 13 that Microsoft has held discussions with Inception, a startup built by a Stanford University team, as the company searches for deals that could add talent and model capabilities. The talks are ongoing and may not result in a transaction, Reuters said, citing people familiar with the matter. Bill Ackman’s Pershing Square, meanwhile, said on May 15 that it has been buying Microsoft stock since February, adding a public investor endorsement as the company defends heavy AI spending. ### Which startup is Microsoft discussing, and what does it do? Inception was founded in mid-2024 and focuses on a different way of building large language models, according to Reuters. Microsoft’s venture fund M12 invested in Inception’s $50 million seed round in late 2025, Reuters reported. Reuters said Inception’s models use diffusion, a technique more commonly associated with AI image and video generation. Instead of producing one token at a time, diffusion systems generate and refine multiple tokens simultaneously, which Reuters said can significantly increase speed. A person familiar with the startup told Reuters that Inception recently hired a bank to help negotiate a deal and is seeking a price of more than $1 billion. Inception declined to comment to Reuters. ### Why is Microsoft looking beyond OpenAI now? Microsoft said on April 27 that it had amended its agreement with OpenAI. Under the new terms, Microsoft remains OpenAI’s primary cloud partner, OpenAI products will ship first on Azure unless Microsoft cannot or chooses not to support the needed capabilities, and Microsoft’s license to OpenAI intellectual property through 2032 is now non-exclusive. The same Microsoft statement said OpenAI can now serve all of its products across any cloud provider and that Microsoft will no longer pay a revenue share to OpenAI. Reuters reported that Microsoft is shopping for startups as it prepares for a future more independent of OpenAI. Three people familiar with the matter told Reuters the acquisitions could help Microsoft add AI talent and support its stated goal of building a cutting-edge AI model by next year.

Microsoft stepped back because of internal concerns that such a deal might not pass regulatory scrutiny, given Microsoft’s ownership of GitHub Copilot, Reuters said, citing people familiar with the matter. (finance.yahoo.com) Reuters also reported that Microsoft faces competition for deals from other technology companies, including SpaceX. SpaceX bought Elon Musk’s AI startup xAI in February and later announced a deal with Cursor after Microsoft walked away, Reuters said. Three people familiar with the matter told Reuters that SpaceX also courted Inception. Reuters said AI researchers can command compensation in the tens of millions of dollars and startup valuations are rising as investors compete for positions in promising AI companies.

Bill Ackman said on May 15 that Pershing Square has built Microsoft into a core holding after starting to accumulate shares in February. (finance.yahoo.com) Fortune reported that Ackman began buying after Microsoft stock fell about 10% following fiscal second-quarter earnings, when cloud growth came in slightly below expectations and capital spending rose. Bloomberg reported that Pershing Square’s Microsoft stake is worth about $2.1 billion. Ackman wrote that he bought at about 21 times forward earnings and argued that investors are underestimating Azure, Microsoft 365, and the economics of the company’s AI investments, according to Fortune. Fortune also reported that Ackman described Microsoft’s 2026 capital expenditure budget as a growth investment rather than a margin threat. (finance.yahoo.com) He said the revised OpenAI arrangement supports a multi-model architecture for enterprise customers, according to the report. ### What are the next concrete markers to watch? April 27 is the date of Microsoft’s amended OpenAI agreement, which set the new contractual terms now framing any additional AI deals. (bloomberg.com) Reuters reported on May 13 that Microsoft’s talks with Inception were still unresolved and could end without an acquisition. Pershing Square disclosed Ackman’s Microsoft position on May 15, and its next formal public detail is expected through the firm’s quarterly 13F filing. (finance.yahoo.com) Any Microsoft-Inception transaction, if one emerges, would likely surface through company statements, securities filings, or a named financing or acquisition announcement by Microsoft, Inception, or M12.
