Microsoft Discloses $10 Billion Quarterly Revenue from OpenAI, Nearly 11% of Total
Microsoft's earnings reveal $10 billion in quarterly revenue from OpenAI arrangements, highlighting deep financial ties despite growing competition.
U.S. technology giant Microsoft disclosed in its regulatory filing for the first quarter of fiscal year 2027, ended September 30, 2026, that it generated $10 billion in revenue from commercial arrangements with OpenAI, including revenue-sharing payments. This figure represents nearly 11% of Microsoft’s total quarterly revenue of $92.3 billion, underscoring the enormous financial ties that remain between the two companies even as they increasingly compete for the same customers.
According to the filing cited by TechCrunch, Microsoft’s revenue from OpenAI hit $24.1 billion for the full 2026 fiscal year. At the latest quarterly pace, Microsoft would pull in approximately $40 billion annually from OpenAI-related arrangements. Additionally, Microsoft reported $7.2 billion in outstanding receivables from OpenAI at the end of September, up from $6 billion at the end of June. This money represents amounts OpenAI owes for previous transactions, not additional revenue.
It remains unclear how much of the $10 billion came from revenue-sharing payments versus Azure cloud computing services. In November 2025, reports citing leaked documents indicated Microsoft had received $865.8 million in net revenue-sharing payments from OpenAI during the first nine months of that year. OpenAI reportedly shares 20% of its revenue with Microsoft as part of a previous deal where Microsoft invested more than $13 billion, though neither company has publicly confirmed this percentage. Under an April 2026 agreement, OpenAI is obligated to continue sharing revenue with Microsoft through 2030, subject to a cap, even as it gains freedom to work with competing cloud providers.
Microsoft’s ownership stake in OpenAI also declined slightly from about 25% in June to 24% in September, continuing a gradual drop from roughly 27% following the October 2025 recapitalization. The company did not specify what caused the dilution. This disclosure provides investors with critical data points for assessing Microsoft’s revenue stability and its exposure to a single major partner.
