Microsoft reported $90.0 billion in revenue and $35.8 billion in net income for the fourth quarter of fiscal 2026, which ended June 30, 2026. That quarter includes a $3.2 billion gain from the company's investment in Anthropic, Azure and other cloud services grew 43%, and commercial remaining performance obligation rose 84% to $678 billion. ASAP works from Microsoft's official earnings release as the primary source to set out where these numbers come from and what they leave unsaid.

A $90 billion quarter inside a $331.8 billion year

Microsoft's fiscal 2026 fourth-quarter revenue was $90.0 billion, up 18% year over year and up 17% in constant currency. Operating income was $40.6 billion, up 18%, and net income was $35.8 billion on a GAAP basis, up 31%, or $35.3 billion non-GAAP, up 22%. Diluted earnings per share came to $4.81 GAAP, up 32%, and $4.74 non-GAAP, up 23%.

For the full fiscal year, revenue was $331.8 billion, up 18% and up 16% in constant currency, with operating income of $155.2 billion, up 21%, GAAP net income of $133.7 billion, up 31%, and GAAP diluted EPS of $17.95, up 32%. Chief executive Satya Nadella stated in the release that Azure revenue surpassed $100 billion for the first time this year.

Growth rates diverge sharply by segment. Intelligent Cloud grew fastest at $39.3 billion, up 32%, while Productivity and Business Processes reached $37.8 billion, up 14%. More Personal Computing declined 4% to $12.9 billion. Microsoft Cloud revenue totaled $59.3 billion, up 27%, the figure chief financial officer Amy Hood highlighted as the release's headline metric.

The $3.2 billion is a mark-to-market gain, not cash earned

The $3.2 billion from Anthropic is a revaluation of an investment position and differs in kind from cash generated by operations. The release places the item in the passage explaining variance against guidance. Several discrete items affected the quarter relative to the forward-looking guidance issued on April 29, 2026, producing a benefit of $0.27 on diluted earnings per share, including the $3.2 billion Anthropic gain and lower-than-expected expenses on the Voluntary Retirement Program, partially offset by severance expense and impairment charges in Xbox.

That sentence structure matters because it separates the growth story from the accounting entries. The nine-point spread between 31% GAAP net income growth and 22% non-GAAP growth originates in items of this type. The portion attributable to cloud demand sits in Azure's 43% growth and Microsoft Cloud's $59.3 billion; the $3.2 billion signals that a private AI company's valuation went up. Placing both on one line and calling it "AI lifted earnings" merges two different events.

The scale of the underlying investment belongs in the same frame. On November 18, 2025, Microsoft, NVIDIA and Anthropic announced strategic partnerships in which Microsoft committed to invest up to $5 billion in Anthropic and NVIDIA up to $10 billion. In the same announcement, Anthropic committed to purchase $30 billion of Azure compute capacity. One side of that arrangement raises the carrying value of an investment while the other books a cloud purchase commitment, and this quarter's $3.2 billion is the first of those two items appearing on the income statement.

The OpenAI line flipped from loss to gain in a single year

The accounting line tied to Microsoft's OpenAI investment reversed direction from a fiscal 2025 loss to a fiscal 2026 gain. The release states that in fiscal 2026, net gains from investments in OpenAI increased net income and diluted EPS by $480 million and $0.07 in the fourth quarter and by $4,963 million and $0.67 for the full fiscal year. In fiscal 2025, the same line was a net loss, reducing net income and diluted EPS by $1,575 million and $0.21 in the fourth quarter and by $3,620 million and $0.49 for the full year.

Taken together, the two years produce a swing of $8,583 million on that single line, calculated by ASAP from the release's own figures. The same stake accounted for the same way moved that far in twelve months, which means Microsoft's quarterly EPS now carries the volatility of private AI valuations. That volatility does not behave like a cloud contract or a software subscription.

This is where investors and buyers should look at different rows. An investor converting GAAP EPS of $4.81 into a growth rate needs to strip this item out first. For an enterprise buying Microsoft's products, the meaningful signals are not the investment line but Azure crossing $100 billion and the $678 billion obligation balance. The more actionable fact for procurement is that Microsoft holds stakes in both Anthropic and OpenAI while selling both companies' models on its own platform.

How $115.9 billion of capex relates to $678 billion of obligations

Capital expenditure including finance leases was $35.8 billion for the quarter and $115.9 billion for the fiscal year. Over the same period, commercial remaining performance obligation increased 84% to $678 billion. Shareholder returns totaled $10.2 billion in dividends and repurchases for the quarter and $48.7 billion for the year, composed of $22.3 billion in repurchases and $26.4 billion in dividends.

Set side by side, those three numbers expose the structure of the bet. Microsoft is spending $115.9 billion a year ahead of revenue on data centers and silicon while pointing to a $678 billion contracted backlog as justification. The 84% growth rate is the load-bearing element of that argument and the only quantitative indicator that demand is running ahead of buildout.

Remaining performance obligation is not revenue. It is the sum of contracted amounts not yet recognized, and recognition spreads across multiple years. Which contracts sit inside that balance, and in what proportion, cannot be determined from the press release. How multi-year compute commitments from large AI companies feed into this line, and what it means when those counterparties overlap with Microsoft's own investees, requires the filings rather than the release. Reading 84% growth in obligations as locked-in future revenue runs ahead of what the line item actually defines.

What the segment that shrank 4% signals

More Personal Computing declined 4% to $12.9 billion, the only one of the three segments to contract. In the same quarter's commentary, Xbox appears as the business carrying severance expense and impairment charges. One segment moving backward in a quarter when total revenue grew 18% signals that the sources of growth are narrowing.

The contrast also shows where the company is shifting resources. Intelligent Cloud's 32% growth and More Personal Computing's 4% decline landed in the same quarter, and the $115.9 billion of capital expenditure flows toward the former. Consumer hardware and gaming are declining in relative weight, and the impairment charges and retirement program are the costs of that adjustment.

What buyers should extract from this table

For anyone running cloud and AI procurement, this release carries three practical signals. The first is supplier scale, visible in Azure's 43% growth and its first $100 billion year. A counterparty growing 43% makes capacity allocation priority a more important variable than discount headroom. In a market where demand runs ahead of supply, volume guarantees deserve attention before pricing.

The second is the case for multi-model sourcing. Microsoft recognized a $3.2 billion gain on its Anthropic investment while recognizing $4,963 million of full-year net gains on its OpenAI investment. Running competing frontier models on one cloud does not conflict with the provider's own business structure, which argues for contracts that preserve the option to switch models rather than ones that lock a workload to a single vendor.

The third is the payback pressure behind $115.9 billion of capital expenditure. Spending at that scale presses on both pricing and capacity policy. Anyone evaluating a multi-year agreement should examine unit-price adjustment clauses and capacity guarantees as separate items, and should use contract structure to avoid ending up a low-priority customer in a market where contracted obligations grew 84% to $678 billion.

Three items to check next quarter

The open questions from this release resolve in the next filing. The first is the direction of the investment marks. The $3.2 billion from Anthropic and the $4,963 million full-year figure from OpenAI are valuation gains, and the record of a $3,620 million loss on the same line in fiscal 2025 shows how far the direction can move.

The second is the trajectory of capital expenditure. How the company guides beyond $115.9 billion a year determines whether this cycle has peaked. The third is the conversion speed of the obligation balance. The durability of Azure's growth rate depends less on the fact that $678 billion grew 84% than on how quickly that amount turns into recognized revenue.
