Microsoft reports fiscal Q4 2026 after the close on Wednesday, July 29 — the same afternoon the Federal Reserve decides — and it arrives as the marquee test of the AI-capex thesis that has been tearing at the Nasdaq.
A top-line beat is close to assumed. The number that will actually move the tape, and the index around it, is capital expenditure.
What the Street Expects
Consensus lands near $4.24 in EPS, up about 16% year-on-year, on revenue of roughly $87.6B , up about 15% — squarely inside Microsoft’s own guide of $86.7–87.8 billion.
Estimates have barely drifted into the print, and the analyst community is overwhelmingly long: a Strong Buy consensus, an average target near $556, and Bernstein’s Mark Moerdler out at $646. The bar for a headline beat is low; the bar for the stock is entirely about the forward story.
Azure — Necessary, Not Sufficient
Azure is the growth engine the market watches first. Microsoft guided 39–40% constant-currency growth for the quarter after printing 40% in Q3, with demand still running ahead of supply and Copilot paid seats past 20 million.
Anything in the high-30s holds the line; a slip below 39% would be read as the first crack in the AI-cloud narrative. But Azure is necessary, not sufficient — in each of the last two quarters Microsoft beat and the stock still fell.
Capex — The Number that Moves the Tape
That’s because the debate has migrated to spending. Microsoft is guiding calendar-2026 capex near $190B, with Q4 outlays above $40 billion — roughly $5 billion of that from higher memory and component pricing. The cost is already visible in cash flow: Q3 free cash flow fell 22% year-on-year to $15.8 billion against about $31 billion of quarterly capex.
The single most important line Wednesday is the FY2027 capex trajectory, because it decides whether the AI build-out is still accelerating and whether that spend ever converts to durable free cash flow rather than margin compression.
Implications for the Nasdaq
This is where the print stops being a single-stock event. Microsoft is one of the three largest Nasdaq-100 weights, so a 7% move mechanically swings the index — but the larger channel is the read-through to semiconductors.
The chipmakers that just cratered (SMH −3.7% Monday, AMD and Teradyne −7%, Micron −6%) are the direct beneficiaries of hyperscaler capex, which sets up the seesaw: a bigger-for-longer capex guide could actually relieve the semis even as it pressures Microsoft’s own margins, while a disciplined capex cut could lift MSFT but gut the AI-levered complex. Timing sharpens it — Microsoft, Meta and Qualcomm all report Wednesday after the close, hours after the Fed, into an NQ already oversold near an RSI of 27. And Alphabet’s disappointing capex-driven quarter last week is the fresh precedent the market is pattern-matching against.
Microsoft is the bigger test, and it sets the tone for Amazon and Apple on Thursday.
