staff report from the Federal Trade Commission has identified several areas of concern in the relationship between Microsoft and OpenAI, including the possibility that the partnership's structure creates anti-competitive dynamics in the market for AI foundation models and AI-integrated software products.
The Exclusive Cloud Deal
At the heart of the concerns is Microsoft's exclusive cloud deal with OpenAI, which routes all of OpenAI's compute through Azure. Critics argue this arrangement effectively forecloses competition at the infrastructure layer, as OpenAI's dominance in language model technology is directly coupled to Microsoft's dominance in enterprise cloud.
The Interlocking Directorate Argument
The FTC report also examines whether Microsoft's equity stake in OpenAI, combined with its board observer status, gives it influence over a competitor's strategic decisions — a pattern the agency identified in its landmark case against Illumina's acquisition of GRAIL. An interlocking directorate argument could theoretically apply even where the relationship is investment rather than acquisition.
“The report's existence ensures that the Microsoft–OpenAI structure will face sustained regulatory scrutiny for years, regardless of who chairs the FTC.”

Regulatory observers expect the matter to proceed slowly, given the complexity of the economic analysis required and the political uncertainty around the new administration's enforcement priorities. However, the report's existence ensures that the Microsoft–OpenAI structure will face sustained scrutiny for years.
