The bond market is showing signs of strain as investors grow increasingly wary of the enormous capital requirements behind the artificial intelligence infrastructure boom.
Credit spreads have widened for major tech companies including Google, Amazon and Meta as fixed-income investors demand higher compensation for lending to firms pouring billions into AI data centers. The pushback intensified this week after Alphabet raised its capital expenditure forecast, stoking fears that other large cloud providers could announce similar increases.
According to CNBC, analysts at Mizuho warned clients Friday that capex increases are testing investor tolerance. Companies once viewed as financial fortresses are now facing sharply rising AI-related costs, with the major cloud providers collectively on track to spend more on capital projects than they generate in free cash flow by next year.
Rising Energy Costs Fuel Budget Growth
Part of the upward pressure on spending comes from energy expenses. Power represents a significant cost for companies constructing large data centers across the United States at an accelerating pace. GE Vernova CEO Scott Strazik told CNBC he expects the current inflationary environment to persist, driven partly by heightened geopolitical tensions. Oil prices broke above $100 per barrel this week, adding to cost pressures.
Movement in Treasury yields has also contributed to fixed-income investor anxiety. The combination of rising benchmark rates and expanding corporate credit spreads is creating what one credit fund portfolio manager described as “intense discussions between bond and equity investors who have exposure to the biggest names in tech.”
Oracle Becomes Proxy for AI Debt Concerns
Oracle’s credit default swaps have emerged as a focal point for these worries. The company’s five-year CDS is once again trading at multi-year highs, with Barclays credit analyst Andrew Keches writing Wednesday that Oracle’s CDS has become a liquid hedge for AI capital spending, OpenAI execution risks and broader data center investment concerns.
Investors are questioning how aggressively Oracle plans to tap debt markets as data center construction and leasing become more capital intensive. Earlier this month, S&P Global downgraded Oracle’s credit rating to BBB-, placing it just one notch above junk status.
Despite the debt market concerns, Oracle executives have expressed confidence in the company’s competitive position, pointing to growing relationships with OpenAI and major technology firms including Meta and Nvidia on cloud infrastructure projects.
Higher Borrowing Costs Ahead
The shift in bond market sentiment is already affecting financing terms for new projects. Meta is working to finance a $12 billion Texas data center, with pricing expected to be finalized early next week, according to a source familiar with the discussions.
The Financial Times reported that the deal will carry a higher borrowing rate than previous projects, signaling that investors not only want greater compensation but are also questioning the return on investment from massive AI infrastructure spending. Portfolio managers told CNBC that the movement in tech bond yields could have implications for financing future deals across the sector.
