Microsoft records $3.2B gain from Anthropic investment in Q4 FY2026

Microsoft disclosed a $3.2 billion gain from its investment in Anthropic during the fourth quarter of its fiscal 2026, which ended June 30, 2026. This gain contributed 33 cents to diluted earnings per share (EPS) for the quarter. Microsoft’s total diluted EPS for the quarter was reported at $4.81.

The company also reported a $600 million write-down on its investment in OpenAI during the same quarter, reducing diluted EPS by about 7 cents. Microsoft owns approximately 27% of OpenAI and accounts for the value of its investment rather than reporting revenue-share payments directly.

Over the full fiscal year, Microsoft’s OpenAI investment generated a $5 billion gain and added $0.67 to EPS, despite the quarterly decline. Microsoft’s fiscal 2026 revenue reached $331.8 billion, with net income of $133.7 billion for the year.

Microsoft’s Q4 FY2026 revenue was $90 billion, with net income of $35.8 billion. The company noted that it does not routinely update the value of its Anthropic investment quarterly, making the $3.2 billion gain an unusual disclosure.
