何が起こったのか
Big Tech firms, including Meta, Nvidia, and Broadcom, have utilized $300 billion in 'residual value guarantees' (RVGs) over the past year to fund AI data centers and semiconductor procurement. By using special purpose vehicles (SPVs) to hold assets and guaranteeing their future value, these companies avoid recording the full debt on their balance sheets, allowing them to maintain credit ratings despite massive capital expenditure requirements that exceed current operating cash flows.
To manage the massive costs of AI infrastructure, hyperscalers and chipmakers are increasingly turning to residual value guarantees. In this structure, an SPV raises financing to build data centers or purchase chips, while the Big Tech firm guarantees a floor price for the asset. This allows the firm to avoid direct borrowing, which would otherwise impact their balance sheets and credit ratings.
Meta has utilized this approach for its 'Hyperion' data center in Louisiana, providing a $28 billion guarantee. Broadcom has similarly engaged in vendor financing, taking on approximately $29 billion in guarantee obligations to supply AI chips to Anthropic. Nvidia has been particularly aggressive, providing a $105 billion guarantee to SB Energy for an OpenAI data center project in Ohio.
The practice exploits a gray area in U.S. GAAP accounting standards. Because these guarantees are contingent liabilities, they often do not meet the 'reasonably certain' threshold required to be recorded as debt. Consequently, while these companies report massive capital expenditures, the associated financial risks remain largely hidden in the footnotes of their financial statements.
Credit rating agencies like S&P Global and Moody's have begun adjusting their assessments to account for these off-balance-sheet commitments. S&P, for instance, adds the difference between the guaranteed value and the expected distressed sale value of assets to a company's leverage, which can add billions to reported debt figures.
なぜそれが重要なのか
This financial strategy obscures the true scale of corporate leverage, potentially masking significant credit risks from investors. As capital expenditures for AI infrastructure are projected to reach $1.2 trillion by 2027, the reliance on off-balance-sheet financing creates a structural vulnerability. If AI demand fails to meet expectations or hardware depreciation accelerates, these contingent liabilities could crystallize into actual debt, impacting the financial stability of the world's largest technology firms.
The reliance on these guarantees is driven by a widening gap between AI-related capital expenditures and operating cash flow. With 2026 capital spending for major cloud companies expected to approach $700 billion, traditional bond issuance is becoming less attractive as it risks downgrades to credit ratings.
There is a significant maturity mismatch risk. While the guarantees are long-term, the underlying AI hardware is subject to rapid obsolescence. If the industry builds capacity that exceeds demand, or if hardware values collapse, the 'selling put options' nature of these guarantees could lead to severe financial strain during a downturn.
The concentration of risk is high, with OpenAI and Anthropic accounting for a large share of hyperscalers' order backlogs. If these frontier AI companies face financial difficulties, the hyperscalers providing the guarantees would be directly exposed to the resulting asset devaluation.

Investors should monitor quarterly report footnotes for changes in guarantee amounts. A decline in these figures as leases commence would suggest the model is functioning as intended, while an increase in guarantee obligations or the quiet withdrawal of platforms could signal that the underlying assets are failing to hold value or that the financing model is becoming unsustainable.
Watch for disclosures in quarterly filings regarding the total value of outstanding residual value guarantees. If these amounts grow, it indicates an increasing reliance on off-balance-sheet financing to sustain AI growth.
Monitor the performance of AI-focused data center projects. If tenants fail to renew leases or if hardware demand shifts, the 'trigger' events for these guarantees become more likely, which would force these liabilities onto the balance sheets of the guaranteeing companies.
Observe the credit rating agencies' commentary on contingent liabilities. Further adjustments to leverage calculations by S&P or Moody's could signal that the market is beginning to price in these hidden risks more aggressively.
