Microsoft openly positions itself as rival to OpenAI and Anthropic on earnings call

Microsoft openly positioned itself as a rival to OpenAI and Anthropic during its latest earnings call, a shift reported by The Daily Star and picked up across business media this week.

According to the report, Microsoft executives' language on the call took on a clearly competitive tone, placing the company opposite leading frontier AI labs. For a tech giant long embedded in the AI ecosystem, such an open positioning is unusual.

Microsoft's relationship with OpenAI has been one of the most closely watched in the industry: as a major investor, it has deeply tied OpenAI's models into its cloud and product lineup. This public stance shows the relationship is becoming more complicated — partner and competitor at once.

Anthropic has also relied on Microsoft as a cloud and compute partner, and it is now being publicly framed as a competitor as well. The declaration is not aimed at any single lab but spans the main players in frontier models.

The shift matters because it signals Microsoft is moving from being a model distribution platform to a model builder competing head-on with the labs it backs. If Microsoft's in-house models keep gaining ground, the boundaries of its cooperation with OpenAI and Anthropic will need to be redrawn.

For the wider AI industry, the change could reshape how frontier labs cooperate with cloud giants, making the "invest-and-compete" dynamic the new normal. It also gives other giants playing both investor and competitor a reference point.

What to watch next: whether Microsoft discloses more of its in-house model work in future calls or launches, and how OpenAI and Anthropic respond to a giant that is now both partner and rival.
