Microsoft Gains $3.2B from Anthropic Investment; OpenAI Performance Mixed

Microsoft announced a record‑breaking fourth‑quarter performance for fiscal 2026, with the quarter ending June 30 reporting revenue of $60.1 billion—up 12 % year‑over‑year—and earnings per share of $3.50, a 15 % increase from the same period last year. The company credited the surge to strong demand for its Azure cloud services, Office 365 subscriptions, and its expanding artificial‑intelligence offerings, all of which contributed to a 22 % rise in operating income.

In its earnings release, Microsoft highlighted the progress of its two largest AI‑lab investments. The company’s stake in OpenAI continues to pay dividends, with the partnership driving significant growth in the Azure OpenAI Service and boosting revenue from generative‑AI applications. Simultaneously, Microsoft’s investment in Anthropic has begun to yield returns as the startup’s Claude model gains traction in enterprise settings, reinforcing Microsoft’s strategy to diversify its AI portfolio across multiple leading research labs.

Looking ahead, Microsoft reiterated its commitment to AI as a core growth engine, noting that both OpenAI and Anthropic are positioned to deliver incremental revenue and cost‑efficiency gains in the coming quarters. The company remains optimistic about sustaining its momentum, with guidance for the next fiscal year indicating continued expansion of cloud‑based AI services and a focus on deepening its collaborations with these key research partners.
