Microsoft boosts AI spending as profit jumps 31.6%
Microsoft reports $35.8bn profit, a 31.6% rise, even as it pours $41bn into AI-capex in the quarter; Azure grows 43% while analysts question the cost-versus-return timeline.
Microsoft reported a sharp rise in profit alongside an aggressive expansion of its AI infrastructure, saying net income for the quarter ended June was $35.8 billion, up 31.6%, and revenue reached $90 billion, up 17.8%.https://www.nytimes.com/2026/07/29/technology/microsoft-quarterly-earnings-report.html The company also disclosed $41 billion in capital expenditures for the quarter, a 69.4% jump from a year earlier, attributing much of that spending to data centers and AI hardware.https://kfgo.com/2026/07/29/microsoft-tops-quarterly-cloud-growth-estimates-easing-spending-concerns/
Microsoft framed the results as proof that heavy investment in cloud and AI is beginning to pay off. CEO Satya Nadella said, “It was a very strong close to what was a record fiscal year for us,” adding that annual revenue topped $331 billion.https://uk.investing.com/news/transcripts/earnings-call-transcript-microsoft-q4-2026-beats-forecasts-stock-jumps-8-93CH-4797053?ampMode=1 But outside analysts and outlets caution that the scale and tempo of spending invite scrutiny over how quickly returns will cover the cost.
Q4 capex hits $41 billion — record fiscal year of $145.3 billion
Microsoft said quarterly capital expenditure reached $41 billion, and reported fiscal 2026 capital spending of $145.3 billion.https://www.nytimes.com/2026/07/29/technology/microsoft-quarterly-earnings-report.html Reuters noted the company forecast about $190 billion in calendar-year 2026 capital expenditures, reflecting continued buildout of data centers and AI-specific hardware.https://finance.yahoo.com/markets/stocks/articles/microsoft-plans-190-billion-capital-214300784.html
Those figures dwarf prior quarters: capex in Q4 was roughly 2.4 times the $17.08 billion Microsoft spent in the year-ago quarter, and up materially from $31.9 billion the company reported in fiscal Q3.https://www.theregister.com/software/2026/07/30/microsoft-earnings-q4-26-cloud-brings-revenue-rain/5280798 The company says the spending addresses past capacity constraints; Reuters reported that easing constraints and rising customer adoption are driving stronger Azure orders.https://kfgo.com/2026/07/29/microsoft-tops-quarterly-cloud-growth-estimates-easing-spending-concerns/
Azure growth (43%) and the $37 billion AI run rate claim
Microsoft highlighted strong cloud momentum: Azure revenue grew 43% in the fiscal fourth quarter, a pace Reuters said exceeded market expectations and signalled a move from buildout to monetisation.https://kfgo.com/2026/07/29/microsoft-tops-quarterly-cloud-growth-estimates-easing-spending-concerns/ Independently, some reporting put Microsoft’s AI business at about a $37 billion annual run rate, up 123% year over year, underscoring how quickly AI services are contributing to revenue.https://finance.yahoo.com/markets/stocks/articles/microsoft-plans-190-billion-capital-214300784.html
Yet not everyone accepts the headline profit growth at face value. The Next Web and other outlets pointed to a one‑time $3.2 billion gain tied to Microsoft’s Anthropic stake that boosted results, and noted that on some company measures excluding investment swings profit rose closer to the low‑20s percentage range rather than 31.6%.https://thenextweb.com/news/microsoft-q4-fy2026-azure-100-billion-ai-spending
Analysts also flag a methodological fog: outlets cite divergent full‑year capex totals — $145.3 billion versus about $115.95 billion in other reports — which likely reflect differences in fiscal vs calendar accounting or inclusion of finance leases. That variance matters when investors judge sustainability of free cash flow under sustained high spending.https://www.nytimes.com/2026/07/29/technology/microsoft-quarterly-earnings-report.html
Microsoft’s bet is explicit: accept temporarily compressed free cash flow to secure capacity and specialised AI silicon now, then monetise through Azure and enterprise software as customers adopt AI at scale. Investors will test that thesis over the next two quarters, watching whether Azure growth sustains and whether Microsoft’s free cash flow stabilises as capex continues at an elevated run rate.
