Microsoft disclosed a $3.2 billion gain from its investment in Anthropic as part of its fiscal fourth-quarter earnings reported on Wednesday, a windfall that boosted diluted earnings per share by 33 cents during a quarter in which the company beat analyst expectations across the board.techcrunch+1
A Lucrative Bet on a Rival AI Lab
The gain stems from Microsoft's $5 billion investment in Anthropic, made in November 2025 as part of a broader arrangement under which Anthropic agreed to purchase $30 billion worth of Azure cloud services. Microsoft does not routinely update the value of the Anthropic stake each quarter, making the disclosure a notable addition to its results.blogs.nvidia+1
The Anthropic gain contributed to Microsoft's reported diluted EPS of $4.81 for the quarter on revenue of $90 billion and net income of $35.8 billion. Revenue grew 18 percent year over year.microsoft
OpenAI: A Contrasting Quarter
Microsoft's OpenAI investment told a different story for the same period. The company wrote down the value of that stake by roughly $600 million, reducing EPS by about 7 cents per share. Microsoft owns approximately 27 percent of OpenAI and receives revenue-share payments, though it does not disclose amounts from that arrangement.techcrunch
On a full-year basis, however, the OpenAI investment generated a $5 billion gain and added $0.67 to EPS. Still, the fact that Anthropic produced nearly as large a gain in a single quarter as OpenAI did over twelve months was notable enough for Microsoft to highlight.techcrunch
Broader AI Investment Context
The quarter's results arrive amid intensifying competition in AI infrastructure. Alphabet reported "other income" gains of $98 billion in its own second quarter, largely from equity stakes in SpaceX and Anthropic. Microsoft's Anthropic partnership, which also involves Nvidia committing up to $10 billion, positions the company to diversify its AI supply chain beyond its long-standing OpenAI relationship.marketwatch+1
For its full fiscal year ending June 30, Microsoft reported revenue of $331.8 billion and net income of $133.7 billion.techcrunch
