The numbers came first, and they were impossible to ignore.
Microsoft stock surged as much as 17% on Thursday, briefly hitting $456 in afternoon trading after closing at $390.54 the prior session. The move added approximately $483 billion in market value in a single day — the largest one-day gain for the stock since 2008, when shares rose 19%, according to Jefferies.
The catalyst was Microsoft's fiscal year 2026 fourth-quarter earnings report, released Wednesday evening. Quarterly revenue reached $90 billion, roughly $2.4 billion above the analyst consensus of $87.6 billion and up $13.6 billion — or 17.7% — from a year earlier. Earnings per share came in at $4.74, well above the consensus estimate of $4.24, on total quarterly net income of $35.8 billion.
Azure crosses $100 billion
CEO Satya Nadella used the earnings call to reveal that Azure, Microsoft's cloud computing platform, crossed $100 billion in annual revenue for the first time during fiscal year 2026. William Blair analyst Jason Ader, who rates the stock outperform, estimated Azure's fourth-quarter revenue at $29.9 billion, up from $20.9 billion a year ago — a 43% growth rate that cleared the company's own guidance of 39% to 40%.
For the full fiscal year 2026, Ader estimated Azure revenues at $104 billion, versus $75 billion the prior year. CFO Amy Hood guided 45% Azure growth for the quarter ending in September, above the 41% analysts had anticipated, according to BNP Paribas.
Microsoft's annual report also disclosed that OpenAI accounted for $24.1 billion in fiscal 2026 revenue, with the AI company still owing Microsoft $6 billion in accounts receivable. BNP Paribas senior equity research analyst Stefan Slowinski estimated that $24.1 billion figure represents less than a quarter — roughly 23% — of Azure's total revenue, and argued Microsoft has a path to sustaining above-40% Azure growth as it phases in consumption-based pricing across its Copilot offerings. Slowinski carries a $549 price target on the stock.
Microsoft 365 Copilot seats surged to 30 million, a single-quarter increase of 10 million seats, well above investor expectations of roughly 6 million, according to Stifel analyst Brad Reback. Commercial remaining performance obligations rose to $678 billion from $368 billion a year ago — what William Blair's Ader called 'tremendous demand visibility across enterprise and AI workloads.'
Reback, who holds a neutral rating, raised his price target from $400 to $450. The stock had entered earnings week down nearly 30% from its October 2025 high of $555, weighed down by investor skepticism over returns on AI capital spending now expected to exceed $850 billion across hyperscalers and cloud providers combined.
What the market is saying
The market has already voted. After months of discounting Microsoft's AI ambitions as expensive and unproven, a single quarter of hard numbers — revenue, margins, and forward guidance all moving in the right direction — erased a year of doubt in one session. That is how free enterprise is supposed to work: capital follows results, not narratives.
For investors who stayed patient, the lesson is straightforward. When a business converts massive capital expenditure into accelerating top-line growth and expanding earnings per share, the stock eventually prices it in. The equilibrium Slowinski described — revenue growth outpacing capex growth — is precisely the signal that separates durable compounders from overcapitalized speculation. Microsoft, at least for now, appears to be making that case.
