Microsoft shops for AI startups as it prepares for life beyond its $13 billion OpenAI partnership

Microsoft Seeks Independence from OpenAI Through Strategic Acquisitions

Microsoft is actively shopping for AI startups as the software giant prepares for a future less dependent on its once-vital partner OpenAI, according to five people familiar with the matter 3

3

. The Microsoft OpenAI partnership, which began with a $1 billion investment in 2019 and has since grown to $13 billion, is entering a new phase as both companies loosen their contractual restrictions 3

3

. This spring, Microsoft weighed acquiring code-generation startup Cursor, but backed away due to internal concerns that such a deal would not pass regulatory scrutiny given Microsoft's ownership of GitHub Copilot 3

3

. The potential acquisitions could help the company stock up on AI talent and deliver on its stated goal of building a cutting-edge AI model by next year 3

Early Doubts About the Partnership Surface in Court Documents

Court documents from the ongoing Musk v. Altman trial have provided a rare look at Microsoft's evolving relationship with OpenAI, revealing that Microsoft executives had reservations about funding the AI lab as far back as 2018 1

1

. When OpenAI CEO Sam Altman requested $300 million worth of Azure cloud computing services in August 2017, Microsoft's AI team saw "no value in engaging," according to a response from Jason Zander, Microsoft's executive vice president at the time 1

1

. A subsequent analysis showed that Microsoft stood to lose about $150 million over several years if it provided the services Altman wanted 1

1

. Microsoft CTO Kevin Scott weighed in on the debate in January 2018, expressing concern about the PR downside of not funding OpenAI and having them "storm off to Amazon in a huff and shit-talk us and Azure on the way out" 2

2

. Microsoft worried that not providing support could push OpenAI into the arms of Amazon, the world's dominant cloud provider at the time 1

Microsoft's Investment in OpenAI and Growing Concerns

Microsoft has spent more than $100 billion on its OpenAI investments and its costs of building infrastructure and hosting, Michael Wetter, who runs the company's corporate development, testified in court 3

3

. Microsoft has given $11.8 billion of its promised $13 billion to OpenAI, according to an April 29 securities filing 3

3

. However, Satya Nadella was worried about OpenAI supplanting his company in the tech hierarchy as far back as April 2022, seven months before the launch of ChatGPT 4

4

. "I don't want to be IBM and OpenAI to be Microsoft," Nadella wrote in an email to executives that April, referring to an earlier technology era when Microsoft became more important than IBM 4

4

. Microsoft's reliance on OpenAI became a strategic vulnerability as the company realized it needed "real agency at every layer of the stack" 4

Active Talks with Inception and Competition from SpaceX

Microsoft is currently in discussions with Inception, a small startup built by a Stanford University team focused on a different method of developing large language models using diffusion techniques 3

3

. Inception was founded in mid-2024, and Microsoft's venture fund M12 invested in Inception's $50 million seed round in late 2025 3

3

. The discussions are ongoing and may not result in a deal 3

3

. Inception recently hired a bank to help negotiate a deal and is looking for a price of over $1 billion 3

3

. Microsoft is facing significant competition for strategic deals from other tech giants, notably Elon Musk's SpaceX, which bought Musk's AI research startup xAI in February and announced a deal with Cursor shortly after Microsoft walked away 3

Microsoft's In-House AI Development and Strategic Shift

Any deals would add to the work under way at Microsoft, including teams led by DeepMind co-founder Mustafa Suleyman 3

3

. The MAI Superintelligence team, set up in November 2025 under Mustafa Suleyman, shipped its first three foundation models in April: MAI-Transcribe-1, MAI-Voice-1, and MAI-Image-2 5

5

. A frontier general-purpose model is the 2027 target for Microsoft's in-house AI development 5

5

. An amended deal in late 2025 allowed Microsoft to build artificial general intelligence, and in late April, OpenAI and Microsoft struck a deal that gives OpenAI the freedom to build some products with Microsoft's rivals, such as Amazon 3

3

. The amendment ended Microsoft's exclusive licence to OpenAI's models and removed the AGI clause that would have triggered changes to Microsoft's intellectual property agreement once OpenAI's board declared the threshold reached 5

5

. Microsoft's position in the AI landscape now depends on diversifying beyond its OpenAI partnership, with Microsoft's AI strategy focusing on acquiring talent and architectural diversity before its in-house programme carries the full weight 5

5

. Both Cursor and Inception target code generation and model architecture, reflecting the working assumption that whoever owns the developer surface owns the next decade in the AI landscape 5
