Key Takeaways
- • AI-related debt issuance reached over $500 billion by late 2026, with total funded debt across the industry and its supporting infrastructure estimated between $400 billion and $600 billion, according to Forbes.
- • Hyperscalers Alphabet, Amazon, Meta, Microsoft and Oracle together carry about $1.35 trillion in balance-sheet debt and $1.65 trillion in off-balance-sheet commitments, per a July 2026 Nikkei Asia analysis of SEC filings.
- • Oracle's five-year CDS spread was about 308 basis points on October 21, more than double its 141 basis points on January 2, a level an S&P Global Market Intelligence executive said resembles BB and B rated borrowers rather than BBB-.
- • CoreWeave's five-year CDS hit a record intraday high of roughly 1,195 basis points on October 15 (ICE Data Services), implying a default probability above 60% over five years at the October peak.
- • Weekly CDS trading tied to Oracle, SpaceX, Alphabet, Amazon, Meta, Broadcom and Nvidia averaged more than $9 billion in September, up from less than $2 billion in July, per Morgan Stanley Research.
Summary
Forbes reports that the AI infrastructure buildout has become one of the most capital-intensive undertakings in recent history, financed through a layered web of investment-grade bonds, private credit, bank-syndicated project finance and off-balance-sheet vehicles. By late 2026, AI-related debt issuance exceeded $500 billion, with total funded debt estimated between $400 billion and $600 billion. The funding is split into three tiers: investment-grade corporate bonds for Big Tech hyperscalers, structured private credit for independent "neocloud" providers, and bank-syndicated project finance for data center developers.
Big Tech borrowers remain comparatively insulated. According to a July 2026 Nikkei Asia analysis of SEC filings, Alphabet, Amazon, Meta, Microsoft and Oracle together report about $1.35 trillion in balance-sheet debt and roughly $1.65 trillion in off-balance-sheet purchase commitments and leases not yet started. Non-bank lenders including Blackstone, Apollo, Magnetar and BlackRock have stepped into financing for startups such as CoreWeave, whose individual debt loads approach $50 billion. Because private credit loans are almost exclusively floating-rate, their servicing costs rise with central bank benchmarks, which Forbes describes as a key vulnerability under the Federal Reserve's "higher-for-longer" stance. JPMorgan and MUFG structured roughly $38 billion in construction financing for data center campuses linked to Oracle, and banks generally originate loans to distribute them to secondary markets.
Forbes highlights asset depreciation as a compounding risk: hardware that may become obsolete within three to five years can leave borrowers with unamortized debt secured by outdated chips. Some private credit-backed loans have shown pricing stress, and refinancing for smaller players may require accepting punitive rates or ceding equity and operational control to lenders. Hyperscalers also guarantee lease payments of smaller infrastructure partners, creating counterparty exposure that may not appear on their initial balance sheets.
Credit market signals have deteriorated. Gartner, in an October 14 analysis cited by Forbes, warned that more than $3.5 trillion of AI infrastructure spending could be exposed to impairment by 2030 if AI revenue falls short. CoreWeave's five-year CDS reached a record roughly 1,195 basis points on October 15 and stood near 1,066 basis points on October 21, per FactSet. Nvidia's five-year spread reached a record 101 basis points and Meta's a record 108 in October, according to Financial Times reporting. SpaceX's contract, which began trading in late June at about 110 basis points, reached a record 226.
Forbes attributes much of the CDS volume to macro hedge funds and bank relative-value desks executing capital-structure arbitrage: going long Big Tech equity or short-dated tech bonds while buying long-dated CDS protection against a broad tech correction. The article notes this activity, not retail or algorithmic flow, is driving the spike in default-insurance volume.
