Microsoft closed the first quarter of fiscal year 2027 — corresponding to the period ending September 30, 2026 — with figures that highlight two increasingly intertwined realities of the technology sector: Azure continues to grow at impressive rates, driven by insatiable demand for AI infrastructure, while the financial relationship between Microsoft and OpenAI reaches proportions that rival major industrial mergers.
Total revenue reached $92.3 billion, a 19% increase year over year, beating market estimates. The standout was the 48% growth in Azure revenue, which generated $33.2 billion in just that single quarter. Total Microsoft Cloud revenue reached $63.9 billion, growing 30% year over year. On a constant currency basis, growth was 31%.
But the number that drew the most attention from regulatory filings was another: $10 billion in revenue generated exclusively from commercial arrangements with OpenAI, including revenue-sharing payments. This figure represents approximately 11% of Microsoft's entire quarterly revenue, highlighting just how financially bound the company remains to the AI lab even as the two become increasingly fierce competitors in the model market.
For the full fiscal year 2026, revenue from OpenAI reached $24.1 billion. At the current quarterly pace, Microsoft would pull in $40 billion annually from OpenAI-related arrangements. By the end of September, Microsoft also reported $7.2 billion in outstanding receivables from OpenAI, up from $6 billion recorded in June — that money represents amounts the OpenAI owes for previous transactions, not additional revenue.
The financial-operational relationship between the two companies runs deep. In November 2025, TechCrunch reported, citing leaked documents, that Microsoft had received $865.8 million in net revenue-sharing payments from OpenAI during the first nine months of that year. OpenAI shares 20% of its revenue with Microsoft as part of a prior deal in which the software giant invested more than $13 billion in the AI startup. Neither company has publicly confirmed this percentage.
Under an April 2026 agreement, OpenAI committed to continue sharing revenue with Microsoft through 2030, subject to a cap, even as OpenAI is allowed to work with competing cloud providers. This loosening of the exclusive partnership began in October 2025, when Microsoft relinquished its exclusive hold on OpenAI, giving the startup more freedom to partner with other cloud providers. In exchange, OpenAI committed to purchasing an additional $250 billion in Azure services.
Microsoft's ownership stake in OpenAI has also declined gradually, from about 25% in June to 24% in September. That dilution continues a broader trend initiated after the October 2025 recapitalization, when the stake was roughly 27%. Microsoft did not specify what caused this additional dilution.
Alongside the OpenAI narrative, Azure showed extraordinary performance. Azure revenue surpassed $100 billion for the first time during the full fiscal year 2026, closing with 43% growth in that period. In the first quarter of fiscal 2027, the acceleration was even more pronounced: 48% growth. That pace puts Azure in an increasingly strong competitive position against AWS and Google Cloud, which also reported robust growth in their respective quarterly results.
Microsoft 365 Copilot, meanwhile, reached over 30 million paid subscribers — a significant milestone for a relatively new product in the enterprise market. Amy Hood, Microsoft's executive vice president and CFO, noted that this number reflects customer confidence in the company's ability to drive AI transformation. Microsoft 365 commercial cloud revenue grew 17% year over year, demonstrating the product is capturing a substantial share of enterprise AI demand.
Microsoft's financial reporting overhaul also warrants attention. To better reflect how the business operates and how resources are allocated, the company updated its reporting system to mirror operational reality. This change reflects a growing pattern among technology companies seeking greater transparency for investors as AI revenues come to represent an increasing share of total earnings.
Microsoft's stock rose 4% in after-hours trading following the results, reflecting investors' positive reception to Azure's performance. The stock had already performed notably throughout the year, contributing to the company's valuation beyond historical milestones.
Meanwhile, other divisions of Microsoft face challenges. Windows OEM and device revenue fell 22% year over year, affected by the end of Windows 10 support during the prior year, OEM inventory drawdowns, and a declining PC market — the global PC sector fell 20% in Q3 according to shipment data. This decline contrasts sharply with cloud expansion, highlighting the structural transformation Microsoft is executing: from a company that historically relied on software licensing to one dependent on cloud services and AI subscriptions.
Market analysts note that the combination of strong cloud growth with record OpenAI revenue creates a unique financial profile in the market. Microsoft not only sells AI infrastructure to third parties — through Azure — but also captures value directly from the AI value chain through its relationship with OpenAI. This dual positioning gives the company a singular standing in the global technology ecosystem.
The question that remains: as OpenAI continues its trajectory toward an IPO and eventually becomes publicly independent, how much of that $40 billion annually will Microsoft be able to maintain? Or will the end of the exclusive partnership mark the beginning of open competition that will redefine industry power dynamics? The next quarter should bring clearer answers about the evolution of a relationship that has become one of the most fascinating elements of contemporary technology.
