Bond Market Worries Grow Over AI Capex
Fixed-income investors are showing rising concern about large AI-related capital expenditures by major tech companies. Yields and credit spreads widened after Alphabet raised its capex forecast, with Google, Amazon and Meta seeing increased borrowing costs. Oracle’s 5-year CDS is trading near multi-year highs and is being used as a proxy for market fears about AI-related debt. Analysts and banks (including Mizuho and Barclays) warn that hyperscalers may spend more on capex than they generate in free cash flow, while energy and power costs are pushing up data-center expenses. The move could affect financing terms for large projects such as Meta’s planned $12 billion Texas data center.
Widening credit spreads and higher borrowing costs for major hyperscalers affect project financing, corporate leverage and the pace/cost of cloud and AI infrastructure buildouts across the tech industry.

Hyperscalers' AI Spending Surge Raises Investor Concerns
During earnings season, hyperscalers including Amazon, Microsoft, Meta and Alphabet signalled dramatically higher AI-related capital expenditure, with combined commitments reported as high as $700 billion for the year. Investors reacted nervously — more than $1 trillion of Big Tech market value was erased in a recent selloff — amid questions about where financing will come from and how quickly the investments will be monetized. Analysts note a roughly 60% year-over-year jump in committed capex and warn that hyperscaler capex could consume nearly 100% of operating cash flow versus a 10-year average of about 40% (per UBS). Concerns include increased borrowing (Oracle planning large debt raises; Alphabet returning to bond markets) and tight payback timelines for data-center and chip investments.
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.
AI Buildout Makes Tech Investors Watch Bond Market
Major technology companies are draining cash reserves and increasingly using debt to finance aggressive AI data-center buildouts, raising investor attention on bond markets and Federal Reserve policy. Amazon, Alphabet, Microsoft and Meta are projected to deploy a combined $750 billion this year (an increase of more than 80% from 2025), while firms such as Nvidia, Oracle and others are tapping debt markets for tens of billions. Rising Treasury yields (the 10-year around 4.45% at publication) and a Fed under Kevin Warsh signaling potential rate hikes increase borrowing costs and valuation sensitivity across the sector. Analysts warn that tech investors must now assess capital-intensity and debt exposure similar to industrial businesses, with broader implications for financing, valuations and future M&A or acquisition financing strategies.
