Big Tech AI spending strains pristine balance sheets
A CNBC Investing Club analysis highlights how massive AI-related capital spending by major technology companies is testing their historically strong balance sheets. Meta Platforms, Amazon, Alphabet and Microsoft have sharply increased data-center and AI server investment, pushing capital expenditures above operating cash flow for some and prompting large debt issuances, long-term leases and alternative financing structures. Credit-rating agencies including S&P Global and Moody’s are monitoring leverage and cash-flow metrics for potential rating pressure, while firms pursue joint ventures and third‑party capital to fund buildouts. Oracle has already seen a rating downgrade amid aggressive spending. The article examines the potential credit and financing implications for hyperscalers and the broader tech-capital markets over the next two to three years.
Major hyperscalers' AI capex and financing strategies affect cloud capacity, corporate credit risk, and capital markets — material for infrastructure, cloud-dependent adtech, and media buyers.

Key Takeaways & Evidence Grounding
- Meta Platforms, Amazon, Alphabet and Microsoft materially increased capex for AI/data centers, contributing to sharply lower free cash flow in recent quarters.
- Combined capex for Amazon, Alphabet, Meta and Microsoft is estimated at roughly $960 billion for calendar 2027, versus projected combined operating cash flow of about $905 billion (FactSet consensus).
- Alphabet, Amazon and Meta have issued large amounts of long-term debt in 2026; Alphabet sold a $25 billion senior note and a recent $3.6 billion Australian bond issuance, while Amazon and Meta completed multibillion-dollar debt offerings.
- Companies are using alternative financing: Meta formed a venture with BlackRock (Meta 20% / BlackRock 80%) for a $14 billion data center campus and has a joint venture with Blue Owl Capital; Nvidia and Broadcom announced third-party financing platforms involving asset managers.
- S&P Global and Moody’s have warned that hyperscalers’ AI buildouts could threaten credit quality; S&P downgraded Oracle to the lowest tier of investment grade in July 2026.

Moody's: AI spending threatens hyperscalers' credit quality
Moody’s Ratings warned that an ‘‘unprecedented’’ surge in AI infrastructure spending is eroding free cash flow and increasing balance-sheet risk at major hyperscalers. In a research note, Moody’s tracked six companies — Microsoft, Amazon, Alphabet, Meta, Oracle and CoreWeave — and highlighted growing use of debt, stock sales and off-balance-sheet financing (mainly long-term data center leases). Moody’s projects capex of $785 billion in 2026 and roughly $1 trillion the following year, with direct debt across the six companies at about $460 billion and lease commitments of $1.2 trillion (over $820 billion not yet started). Moody’s said strong balance sheets at Microsoft, Alphabet, Amazon and Meta make immediate rating downgrades unlikely, while pressure is concentrated on lower-rated entities such as Oracle and CoreWeave.
Allianz Research Warns of Rising Credit Risk in AI Infrastructure Boom
Allianz Research warns that the massive expansion of AI infrastructure is increasing credit risk for major US tech companies, as long-term off-balance-sheet commitments are not fully reflected in balance sheets. The study analyzed eight US tech firms and found their long-term debt increased by 86% in the year to mid-2026. When including off-balance-sheet commitments such as future data center leases and infrastructure obligations, the total for Alphabet, Meta, Oracle, Microsoft, and Amazon reached nearly $2.6 trillion in August 2026, up from $573 billion a year earlier. These commitments could lower credit ratings by one to two notches. CDS spreads have more than doubled, but markets have not fully priced in the risk. Equity volatility is a key factor, and a stress scenario could widen spreads by about 20 basis points. The report highlights the asymmetric risk: shareholders benefit from AI upside, while creditors bear the downside.
Big Tech's AI Spending Masks Earnings Risks
An opinion analysis of recent Big Tech earnings argues that exceptional revenue growth masks underlying risks driven by massive AI investments and accounting mark-ups. Microsoft, Amazon, Meta, and Google reported unusually high revenue growth, but also record capital expenditures (e.g., Google ~$45B and Amazon ~$54B in one quarter) and negative cash flows tied to AI infrastructure spending. Research cited estimates that OpenAI and Anthropic account for a large share of some platforms' AI revenue (e.g., ~73% of Amazon’s AI revenue and ~70% of Microsoft’s AI sales), raising concerns that Big Tech growth is heavily reliant on a small set of unprofitable AI companies. The piece concludes Big Tech would be re-rated if AI expectations fail, but the firms would not collapse — rather, they would be shown as mature companies reallocating priorities.
