Microsoft logs $3.2B from Anthropic investment, but OpenAI was a mixed bag

Microsoft said its Anthropic stake boosted quarterly earnings by $3.2 billion, while its OpenAI investment was marked down by about $600 million.

For the full fiscal year, Microsoft said its OpenAI holding generated a $5 billion gain.

The results highlight the uneven financial impact of Microsoft’s AI bets across rival labs.

They also underscore the scale of Microsoft’s broader AI ecosystem investments and Azure-linked partnerships.
