Microsoft is heading deeper into the AI infrastructure spending cycle, but BNP Paribas argues the company’s free cash flow (FCF) profile is still the most resilient among hyperscalers, even as the sector collectively accelerates capital expenditures.
The call comes at a moment when investors are increasingly treating “AI capex” as the central risk variable for Big Tech: the bigger the buildout, the more near-term pressure on reported FCF — and the more scrutiny on whether cloud growth is keeping pace.
The key point: Microsoft can “absorb” capex better than peers
Microsoft’s advantage, in BNP Paribas’ framing, is not that capex is small — it isn’t — but that the company’s cash generation and monetization engines are diversified enough to keep cash conversion comparatively steady.
In Microsoft’s fiscal Q2 (quarter ended Dec. 31, 2025), the company reported net cash from operations of $35.76B, while additions to property and equipment were $29.88B. That implies quarterly FCF of roughly $5.88B (operating cash flow minus capex), a stark illustration of how fast AI-driven infrastructure investment can compress near-term FCF even in a cash-rich platform business.
BNP’s conclusion: even with that compression, Microsoft’s FCF is still the “cleanest” in the peer set because it has multiple high-margin, recurring revenue streams (Productivity, Security, Windows commercial, and a broad cloud attach motion) helping fund the buildout.
The “Big 5” capex arms race is the backdrop
The note also lands as forecasts for hyperscaler spend move higher. The Seeking Alpha item citing BNP Paribas points to nearly $700B of capex for the “Big 5” hyperscalers, up sharply year-over-year and above prior expectations.
Separate disclosures underscore how quickly the spending plans are scaling:
- Alphabet has discussed a major step-up in 2026 capex tied to AI and cloud infrastructure.
- Amazon has also outlined very large 2026 capex intentions focused on AI infrastructure buildout.
What “resilient FCF” means for investors
1) Valuation support in a capex-heavy regime
When the market is worried about “capex swallowing cash flow,” the companies with the most dependable cash generation tend to hold valuation better. BNP’s thesis effectively argues Microsoft should remain in that “premium” bucket.
2) Less binary outcomes
Some peers are more dependent on a narrower set of cash engines. Microsoft’s breadth (enterprise software + cloud + developer + security + advertising + gaming) can smooth the path through the build cycle.
3) The near-term FCF print may stay noisy
Even if Microsoft is “most resilient,” the math is the math: as long as capex stays elevated, quarterly FCF can remain volatile. The investment debate shifts from “is FCF down?” to “is the installed capacity monetizing fast enough?”
Conclusion
BNP Paribas’ message is essentially a relative one: AI capex is pressuring everyone’s free cash flow, but Microsoft is viewed as best positioned to withstand it thanks to scale, recurring revenue, and monetization breadth. The market may still react to capex spikes quarter-to-quarter — yet on BNP’s view, Microsoft’s cash-generation base makes it the hyperscaler with the most durable FCF profile through the cycle.
FAQ
Why is Microsoft’s free cash flow getting squeezed if the business is strong?
Because capex is surging. In the latest reported quarter (ended Dec. 31, 2025), operating cash flow was about $35.8B while capex (property and equipment additions) was about $29.9B, leaving roughly $5.9B in implied FCF.
Does “most resilient” mean Microsoft’s FCF will rise soon?
Not necessarily. It means BNP expects Microsoft to hold up better than peers during the spend cycle — not that FCF won’t be pressured while buildout remains intense.
What’s the biggest swing factor from here?
The pace of monetization: whether Azure growth, AI services, and enterprise software attach can ramp quickly enough to offset depreciation and ongoing infrastructure investment.
Is the whole hyperscaler group raising capex?
Yes. The BNP/Seeking Alpha summary flags a major increase for the large cohort, with separate company-level signals from Alphabet and Amazon pointing to sharply higher 2026 spend tied to AI infrastructure.
