Azure just crossed a threshold no cloud unit at Microsoft had reached before. On Thursday, the company’s cloud computing arm topped $100 billion in quarterly revenue for the first time, and the stock is having its best day in years because of it.
Shares of Microsoft traded near $427 in early Thursday action, up roughly 9% from Wednesday’s $390.54 close, after the company’s fiscal fourth-quarter results beat Wall Street’s numbers on both revenue and profit. By midday, other coverage had the stock’s gain running as high as 16%, with shares on pace for their best single-session performance since 2008.
That is a wide range for one trading day, and it says something about how fast this tape is moving. Microsoft entered Thursday down about 19% year-to-date. Today’s rally doesn’t erase that hole — it dents it.
What actually drove the number
Bank of America framed the quarter bluntly. Revenue grew 17% year-over-year in constant currency, and earnings per share reached $4.74 — ahead of the Street’s $4.25 estimate, according to commentary carried by CNBC. The firm called it validation of Microsoft’s AI strategy, not just a beat.
The mechanism is straightforward. Azure’s growth rate is the market’s proxy for whether the hundreds of billions of dollars hyperscalers are pouring into AI infrastructure are actually converting into paying cloud customers. When that number accelerates instead of plateauing, it changes the math on every dollar Microsoft has committed to GPUs and data centers — the spending looks funded by revenue rather than by faith.
That’s also why the reaction here reads as a relief rally as much as a growth story. Alphabet took the opposite path last week, raising its 2026 capital expenditure outlook to as much as $205 billion and watching its stock fall more than 6% on the news. Microsoft spent the money and showed the growth. Alphabet raised the number and got punished. Investors are drawing a line between the two.
The broader tape is climbing out of a hole
Thursday’s gains sit on top of Wednesday’s damage. The Dow fell 1,153 points, or 2.19%, on Wednesday — its worst day since April 2025 — after the Federal Reserve held interest rates steady with three voting members dissenting in favor of a hike, according to CNBC’s live markets coverage. The S&P 500 lost 1.52% that session and the Nasdaq fell 1.74%, pulling the index more than 10% off its record high.
Thursday is a partial reversal, not a full one. Early trading had the S&P 500 up roughly 0.6% to 0.9% and the Nasdaq up between 1.6% and nearly 3%, depending on the point in the session, per TheStreet’s live blog and a separate midday update from Stock Market Watch. The Dow’s move has been smaller, adding somewhere between roughly 200 and 500 points across different points in the session. The Russell 2000, notably, was not along for the ride — TheStreet had the small-cap index down 1.61% even as the mega-cap-heavy Nasdaq surged, a split that says this rally is concentrated in a handful of names rather than broad-based.
Semiconductors caught a bid alongside Microsoft. The Nasdaq 100 climbed roughly 3% a day after entering a technical correction, and chip names that had been sold hard this week rebounded as the AI-infrastructure trade found its footing again.
The bond market hasn’t gotten the memo
None of this has cooled the Treasury market. The 10-year yield was holding around 4.68% on Thursday after climbing nearly 10 basis points in the prior session, according to Trading Economics. The 30-year yield pushed to its highest level since 2007. Fed Chair Kevin Warsh told reporters Wednesday the decision to hold rates steady shouldn’t be read as policy inertia, and markets are now pricing roughly even odds on a hike rather than a cut at the next meeting — a sharp reversal from the near 80% odds of steady policy priced in before Wednesday’s decision.
That’s the tension sitting underneath today’s rally: equities are celebrating a single company’s execution while the rate market is still digesting a Fed that sounded more hawkish than expected. Higher long-end yields typically weigh hardest on exactly the kind of long-duration growth names leading Thursday’s bounce, which is why this move looks more like a relief bounce in oversold names than a shift in the macro picture.
What’s next
Amazon and Apple both report earnings after Thursday’s close, and both face a higher bar than Microsoft cleared. Amazon’s AWS cloud unit will get compared directly against Azure’s new $100 billion mark. Apple’s report will be read for margin pressure from rising memory chip prices. Either result could extend Thursday’s rally into Friday — or reset it, the way Alphabet’s capex guidance reset sentiment last week.
