Major technology companies are issuing record levels of debt to finance the expansion of AI data centers and infrastructure. According to R&D World, AI-related debt issuance reached nearly $500 billion by early August 2026. Big Tech raised a record $108 billion in debt in 2025, more than three times the previous nine-year average. Specific companies, including Alphabet, Amazon, and Microsoft, have significantly increased their capital expenditure and debt loads to purchase GPUs and build data centers, while Oracle has accumulated substantial debt and leases partly driven by its contract with OpenAI.
R&D World reports that hyperscalers are borrowing at record levels to build data centers, with AI-related debt issuance reaching nearly $500 billion in 2026 by early August, according to Goldman Sachs. This buildout is aimed at both commercial customers and the companies' own AI products.
Big Tech raised a record $108 billion in debt in 2025, more than three times the average over the previous nine years, according to Nomura. Goldman Sachs estimated that about 40% of this year’s AI-related debt supply has been issued directly by hyperscalers, including Amazon, Microsoft, and Alphabet.
Alphabet’s debt has risen to about $100 billion, with the company raising its 2026 capital expenditure outlook to $195 billion to $205 billion. Amazon expects about $220 billion in 2026 cash capex, an increase of $20 billion from previous plans, attributed to rising memory prices and the need to buy Nvidia and AMD GPUs. Microsoft is shifting data center leases from finance to operating leases, which lowers its reported 2026 capex to about $175 billion without changing investment plans.
Oracle has accumulated about $137 billion in debt and leases, with S&P estimating that half of its $638 billion backlog comes from OpenAI. OpenAI itself reportedly had no debt as of March 31, 2026, but its partners, such as SoftBank, are borrowing heavily; SoftBank secured a $40 billion bridge loan in March to fund OpenAI investments.
なぜそれが重要なのか
The shift toward debt financing for AI infrastructure signals a massive, long-term capital commitment by the industry, moving beyond equity funding to leverage balance sheets for physical buildout. This trend highlights the critical role of access in AI development, as academic researchers and smaller entities face severe constraints while hyperscalers secure capacity. The financial structure of this buildout, involving bridge loans and massive capex increases, indicates that the AI race is now a test of financial endurance and infrastructure scale, with significant implications for market stability and the distribution of computational resources.
The reliance on debt for AI infrastructure indicates a strategic shift in how the industry funds its growth, moving from equity to leverage. This has practical implications for the availability of , as the buildout is primarily serving hyperscaler needs and their commercial clients.
The article highlights a disparity in access, noting that while hyperscalers expand, academic researchers face severe constraints. A 2024 survey found 85% of academic AI researchers had zero cloud compute budget, and the Digital Research Alliance of Canada awarded only about 31% of requested GPU time in 2025.
The financial scale of the buildout, with companies like Alphabet and Amazon increasing capex by tens of billions of dollars, suggests that the AI race is becoming a test of financial and logistical endurance. This may consolidate power among a few large players who can afford the debt burden.

次に見るべきもの
Monitor the sustainability of hyperscaler debt levels and any potential credit rating changes. Watch for updates on the completion of data center projects and whether the increased capacity alleviates the shortage for non-hyperscaler entities. Track the financial health of AI startups like OpenAI, which rely on debt-financed partners for infrastructure.
Investors and analysts should watch for any signs of financial strain or credit rating downgrades among hyperscalers as debt levels rise. The sustainability of this debt-fueled growth is a key risk factor for the AI sector.
The completion of new data centers and the subsequent availability of capacity will be critical. Will this expansion lead to a decrease in GPU prices or improved access for smaller companies and researchers, or will it remain concentrated among the largest players?
The financial health of AI startups, particularly those with large infrastructure contracts like OpenAI, will be closely monitored. The reliance on debt-financed partners for infrastructure could create vulnerabilities if those partners face financial difficulties.
