Microsoft earnings show $7.6 billion boost from OpenAI investment

On Wednesday, Microsoft reported quarterly revenue of $81.3 billion, representing a 17% increase compared to the same period last year. This revenue figure beat Wall Street analyst expectations, which had anticipated $80.27 billion. A portion of Microsoft’s financial gains came from its investment in OpenAI, which resulted in a $7.6 billion increase in Microsoft’s net income for the quarter.

The relationship between the two companies follows renegotiated deal terms in September 2025, which occurred when OpenAI restructured into a public benefit corporation—a type of for-profit corporate entity that includes positive impact on society in its charter. Microsoft has invested more than $13 billion in OpenAI. The AI lab is currently looking to raise additional funding at a valuation between $750 billion and $830 billion, Bloomberg reported. Under their agreements, OpenAI reportedly has a 20% revenue share agreement with Microsoft and agreed to buy $250 billion of Azure services. This commitment shows on Microsoft’s books as commercial remaining performance obligations—defined as contracts that have not yet been paid out. These obligations leaped to $625 billion from $392 billion in the previous quarter, and Microsoft stated that 45% of this total is from OpenAI.

Microsoft is also working with Anthropic to boost anticipated future revenue. In November 2025, Microsoft announced a $5 billion investment in Anthropic, and the AI lab signed up for $30 billion of Azure compute capacity. This partnership helped boost Microsoft’s anticipated future revenue in the form of commercial bookings—defined as anticipated future revenue—which grew by 230% during the quarter. To support these cloud services, Microsoft spent $37.5 billion on capital expenditures—defined as funds used by a company to acquire, upgrade, and maintain physical assets—during the quarter.

Overall, Microsoft Cloud revenue reached $50 billion, representing 17% growth. Other business segments saw different results; Windows devices growth was essentially flat at 1%, while Xbox content and services declined by 5%.

• Reported Revenue: $81.3 billion (up 17% year-over-year)
