Microsoft's AI Revenue Tops $30 Billion as Software Giant Pursues OpenAI Independence

Strong Q3 earnings and Azure growth overshadowed by strategic shift away from OpenAI, with $100B+ investment and new AI deals reshaping Microsoft's future.

The numbers coming out of Redmond tell a story of operational muscle. Microsoft’s Azure cloud platform grew 39 percent on a constant-currency basis in the fiscal third quarter, its AI assistant Copilot crossed the 20 million user threshold, and total revenue jumped 18 percent year over year to push earnings per share to $4.27. Yet the stock is down roughly 14 percent since January, closing Wednesday at €346.10 and sitting well below its 200-day moving average. The disconnect between a thriving business and a struggling share price is explained not by a loss of product momentum, but by a fundamental restructuring of Microsoft’s most important partnership.

For years, the alliance with OpenAI looked like the perfect bet. Behind the scenes, that bet has ballooned. A Microsoft manager testified this week in the ongoing Elon Musk–Sam Altman trial that the company has funneled more than $100 billion into the relationship — $13 billion in direct equity investments plus enormous sums for custom Azure cloud infrastructure. The revenue generated from the partnership reached roughly $9.5 billion by spring 2025, and Microsoft now estimates total AI-related income across recent years at over $30 billion. Those returns, however, come with a strategic price tag that the market is only now fully weighing.

Microsoft is racing to reduce its dependence on OpenAI. In April 2026 the exclusivity clause in their deal expired, allowing OpenAI to offer its products on rival clouds such as Amazon Web Services and Google Cloud. Simultaneously, Microsoft secured the right to develop its own artificial general intelligence and made a $5 billion investment in OpenAI competitor Anthropic. The company is also in talks to acquire Inception, a Stanford-birthed startup specializing in diffusion technology for large language models, at a price exceeding $1 billion — though SpaceX has also expressed interest in the year-old firm. Earlier, Microsoft walked away from a planned purchase of Cursor after antitrust concerns surfaced around its GitHub Copilot service. The goal is clear: have proprietary AI models ready by 2027.

The operational engine, meanwhile, continues to hum. A massive $627 billion commercial backlog provides long-term revenue visibility, and analysts remain broadly bullish. Phillip Securities upgraded the stock to "Buy" on May 13 with a $485 target, while Wedbush and Citigroup reaffirmed their positive stances. Citi’s $620 price target is among the highest on Wall Street, and the consensus analyst estimate sits near $569. The current price-to-earnings ratio of 24 stands well below the stock’s historical average, a valuation gap that some see as a buying opportunity.

Institutional investors have already moved. Aspiring Ventures increased its stake by almost 160 percent in the first quarter, and both Revisor Wealth Management and Krilogy Financial added to their positions. Insider trading tells a more mixed story: Vice President Hogan sold shares at an average of $409 in March, while Director Stanton bought at roughly $397 in February. Shareholders can also look forward to the quarterly dividend of $0.91, payable in mid-June to those on record as of May 21.

The courtroom drama in Oakland adds another layer of uncertainty. Closing arguments are set for Thursday, with jury deliberations beginning Monday. The outcome of Musk v. Altman will shape how Microsoft justifies its future AI spending and profit margins to investors. For now, the company is balancing record cloud revenue and a growing AI user base against a costly and deliberate pivot away from OpenAI — a pivot that may take years to fully pay off, and that the stock has already begun to price in.
