MICROSOFT CUT THE CAPEX NUMBER—NOT THE AI BUILD Microsoft lowered its 2026 capex forecast from roughly $190 billion to $175 billion, but this was not a $15 billion retreat from AI infrastructure. It was largely a change in how the spending appears in the accounts. The accounting matters Microsoft extended the estimated useful life of its data centers and office buildings from 15 years to 25 years. That spreads depreciation across another decade, reducing the annual expense recognized against assets that are already unusually difficult to value economically. More future data-center leases will also be classified as operating leases, pushing those commitments outside reported capex. The servers, buildings and power contracts do not disappear because the accounting category changes. Management made the important point directly: underlying investment plans remain unchanged. Capex reached $41 billion this quarter, and Microsoft plans to spend more than $50 billion in the current quarter, including the reclassified investment. That is acceleration, not austerity. Why Microsoft gets more room The difference is that Microsoft can currently show investors where the money is going. Azure grew 43%, accelerated from 40% last quarter and is expected to grow 45% next quarter because customer demand still exceeds available capacity. Azure also surpassed $100 billion in annual revenue for the first time. Copilot reached 30 million paid users, up from 20 million in a single quarter and ahead of the 26 million analysts expected. Companywide revenue rose 18% to $90 billion, while net income climbed 31% to $35.8 billion. Microsoft also has $678 billion in remaining performance obligations supporting future revenue visibility. Most importantly, it stayed free-cash-flow positive and expects to remain so throughout the current fiscal year. That does not make $175 billion of annual capex cheap, nor does it prove every AI data center will earn an adequate return over its newly assumed 25-year life. It does mean Microsoft’s spending is being supported by accelerating cloud demand, expanding paid AI adoption and internally generated cash. Bottom line: Microsoft has not become more capital-disciplined—it has become better at proving it can carry the capital intensity.
