Two of the planet's biggest AI spenders open their books within hours of each other tonight, both after the closing bell. Yesterday I called this earnings week a referendum on AI capex; today the two heaviest spenders actually get their votes counted. Three items, one throughline: the market has stopped grading these companies on what they earn and started grading them on what they spend.
Microsoft's FY2027 capex is the whole ballgame
Microsoft reports fiscal fourth-quarter 2026 after the close today, and the company confirms the release lands July 29, 2026. Wall Street is looking for roughly $87.67 billion in revenue and EPS of $4.24, per reporting on the estimates, and a beat is close to a formality — Azure was guided to 39–40% constant-currency growth, in line with last quarter's 40%, according to TradingKey. The number that actually moves the stock is FY2027 capital-expenditure guidance: Yahoo Finance notes analysts want to see growth of 20–30%, landing near $220 billion, which would read as discipline against Azure's growth rather than a blank check. For context, last quarter Microsoft's AI business crossed a $37 billion annual run rate, up 123%, with Microsoft 365 Copilot topping 20 million paid seats, per CNBC.
The operator's take: Azure is the rent; capex is the mortgage your landlord is taking out to build more of it. If FY2027 capex comes in well above that ~$220 billion and Azure growth doesn't accelerate to match, the gap gets paid down somewhere — and historically that somewhere is customers, through price and packaging. Watch the capex-to-Azure-growth ratio, not the headline beat; that ratio is the leading indicator for your 2027 renewal.
Meta already deferred part of tonight's bill
Meta reports Q2 2026 after the close today too, with revenue expected near the top of its own $58–61 billion guide, per moomoo. The tension is the one that's dogged the stock all year: earlier this year Meta raised 2026 capex to $125–145 billion, up from $115–135 billion, as Yahoo Finance reported. Here's the wrinkle that makes tonight interesting — Meta actually underspent in Q1, laying out $19.84 billion against a roughly $27.6 billion estimate, which means the deferred spending has to land in the back half; run the guidance forward and it implies $35–42 billion a quarter for the rest of 2026, per indmoney. And a beat may not be enough: last quarter Meta beat on both revenue and EPS and still fell 6–7% purely on the capex line.
The operator's take: this is the clearest tell that the AI bill doesn't disappear — it just moves quarters. When a vendor "underspends," don't read it as restraint; read it as a payment deferred. If Meta is your ad channel, the pressure to monetize that back-loaded capex shows up as higher ad prices and more aggressive automated placements. Budget for your cost-per-result to drift up as their depreciation does.
The bigger math: the hyperscalers are spending toward negative cash flow
Step back from any single report and the aggregate is stark. Combined capex at the big hyperscalers is modeled to reach $801 billion in 2027 — enough to push them all free-cash-flow negative through 2028 — per IG citing Refinitiv, with Meta's own 2027 capex modeled near $205 billion tied to a 14-gigawatt buildout.
The operator's take: your most important vendors are voluntarily going cash-flow negative to fund infrastructure you depend on, and companies that burn cash eventually have to earn it back or raise it. Both routes reach you — as pricing, as tighter free tiers, or as a dependency on debt markets that can seize up. Treat multi-year AI commitments the way you'd treat lending to a business that's FCF-negative by design: keep the term short and the exit clean.
Also on my radar
- Seagate beat and raised guidance, and after sliding 8.5% into the print the stock rebounded more than 10% after hours (TradingKey). The picks-and-shovels trade — storage for all that AI data — is still paying while the platform names get audited.
- Microsoft has shed roughly 24.69% year to date even after 18% revenue growth last quarter (eciks). The market has already repriced the capex risk; tonight decides whether it overshot.
- Meta is reportedly in cloud talks with Anthropic and has launched Muse Spark 1.1 (Yahoo Finance). Even a company spending nine figures on its own AI still shops for outside models — build-vs-buy stays live even at Meta's scale.
The throughline: yesterday the market put AI spending on trial; tonight two of the biggest defendants take the stand, and the verdict won't turn on revenue — it'll turn on the size of the invoices they're signing for 2027. Operators should watch the capex lines, not the beats, because those lines are the leading edge of your own 2027 costs. That's the Signal for today.
