- The article discusses the potential impact of massive AI-related capital expenditures by tech giants on their future earnings. While AI investments are expected to boost long-term revenue, the author raises concerns about margin compression and declining ROIC as these assets depreciate. The question is whether this is a temporary phase or a sign of future earnings lagging revenue, posing a near-term risk to valuations.
Big tech is currently pouring record amounts of capital into AI infrastructure,data centers, GPUs, and networking. Estimates suggest hyperscalers could collectively spend over $600B+ on AI capex in 2026 alone,one of the largest investment cycles the tech sector has ever seen. That raises a question,What happens when all this capex starts flowing through the income statement as depreciation? Historically, heavy infrastructure cycles tend to
1)Boost revenue potential long term 2)But compress margins and ROIC in the medium term
Some analysts are already warning that returns on invested capital for companies like Microsoft and Alphabet could decline as these assets begin to depreciate over the next several years. At the same time, the spending race doesn’t seem to be slowing ,Meta alone recently expanded a single AI data center project to $10B, highlighting how aggressive this buildout has become. So I’m curious how others are thinking about this from an investing standpoint:
Is this just the early stage of a multi-year infrastructure cycle similar to the early cloud era? Or are we setting up for a period where earnings growth lags revenue because of depreciation and operating costs?
Are you treating AI capex as a long-term bullish signal for megacaps, or a near-term risk to margins and valuation multiples?
