Summary: Microsoft’s fiscal 2026 second quarter beat estimates with $81.3 billion revenue, up 17%, and $38.3 billion operating income, up 21%, but the stock fell 10% on January 29. Azure grew 39%, commercial remaining performance obligations reached $625 billion, and capital spending nearly doubled year over year. Investors focused on AI capex payback and Microsoft’s concentrated exposure to OpenAI.
Microsoft published its fiscal 2026 second-quarter results — covering October through December 2025 — after the close on January 28, 2026: revenue of $81.3 billion, up 17%, and operating income of $38.3 billion, up 21%, clearing expectations on both the top and bottom lines. The verdict from the market arrived the following session: a 10% plunge to a $433.50 close on January 29, leaving the stock as the heaviest drag on the Dow Jones Industrial Average that day, with media tallies putting the erased market value at roughly $360 billion.
A beat that strong meeting a selloff that brutal is really a story about where attention went: investors stopped reading the quarter itself and started pressing on two questions with no easy answers — how long AI capital spending takes to earn its money back, and what to make of the ever-tightening accounting ties between Microsoft and OpenAI.
On Paper, an Unambiguously Strong Quarter
Microsoft Cloud brought in $51.5 billion, 26% higher than a year earlier; Azure and other cloud services expanded 39%, or 38% with currency effects stripped out. The finer lines: Microsoft 365 Commercial cloud rose 17%, consumer cloud 29%, LinkedIn 11% and Dynamics 365 19%, while Xbox content and services declined 5% and Windows OEM was flat. Across the three segments, Productivity and Business Processes brought in $34.1 billion (+16%) and Intelligent Cloud $32.9 billion (+29%), with More Personal Computing the lone decliner at $14.25 billion (-3%). The line that really stood out was commercial remaining performance obligation: $625 billion, a 110% year-over-year jump. Cloud commitments that are signed but not yet delivered more than doubled within a year, and AI demand drives most of it — the clearest single indicator that enterprise AI budgets are already locked in, regardless of who ends up booking the revenue.
The Net Income Surge Has an OpenAI Footnote
GAAP net income reached $38.5 billion, 60% above last year, for diluted EPS of $5.16; non-GAAP diluted EPS came to $4.14, up 24%. Inside that headline figure, $7.6 billion — $1.02 per share — was this quarter’s markup on Microsoft’s OpenAI stake; a year earlier, the same line produced a $939 million loss. In other words, a sizable share of the GAAP jump is valuation noise on a holding rather than anything earned by operations. The non-GAAP figure — net income of $30.9 billion, up 23% — hews closer to how the business actually ran. Here lies the market’s first worry: quarter after quarter, OpenAI’s valuation now feeds straight into Microsoft’s income statement, in either direction.
Capital Spending Almost Doubled in a Year
The cash flow statement shows additions to property and equipment of $29.9 billion this quarter against $15.8 billion a year earlier — close to a doubling — and the first half of the fiscal year has already consumed $49.3 billion. Operations generated $35.8 billion of net cash, so capital spending swallowed more than 80% of it, while another $12.7 billion went out in dividends and buybacks. Reuters reported that the question Wall Street keeps raising is when all this spending converts into revenue growth, and Microsoft’s concentrated exposure to OpenAI makes the answer harder. The same week split Big Tech in two: Meta climbed on AI-driven advertising revenue while Microsoft absorbed the punishment.
What Investors Are Actually Weighing
Investopedia’s market wrap put the contradiction plainly: revenue and earnings each topped analyst estimates, and the stock still sank 10%. The explanation sits not in the quarter but in the discount model: once the capex curve outruns the AI revenue curve, even solid absolute numbers stop protecting a valuation. The worry is not Microsoft’s alone — this selloff breathed fresh life into AI-spending anxiety across the software industry, which had already lost more than 10% since the start of the year.
Three Takeaways for AI Product Teams
One: keep the $625 billion RPO at the top of your watch list — enterprise AI demand is bound by contract, which gives Azure’s growth a floor for the next several quarters. Two: what platform companies spend on AI is turning into everyone else’s input cost — products built on Azure or OpenAI will watch pricing and margins move with these earnings cycles, a chain effect we pointed to in our 2026 opening outlook. Three: the route OpenAI’s gains take through the income statement is a warning for anyone making architecture decisions — a supplier you count on is itself woven into another company’s accounting fate, so concentration risk now lives at the supply-chain level.
