Broadcom’s extensive AI debt backstops have elevated its credit risk metrics to record levels.
Broadcom’s (NASDAQ: AVGO) AI debt backstops have pushed the company’s credit default swaps to a record 122 basis points, shifting the terms of the debate from equity investors to bond investors. This spike followed Broadcom’s August 20 announcement to arrange up to $100 billion through off-balance-sheet vehicles designed to purchase AI chips and lease them to customers. Bank of America estimates the platform could carry approximately $370 billion in senior debt by mid-2029.
The mechanics behind these transactions matter more than the headline figures. A special-purpose vehicle borrows capital to buy chips, which it then leases to an AI company—Anthropic serves as the anchor client in Broadcom’s initial deal. Broadcom does not borrow the funds directly; instead, it backstops a portion of the senior debt, promising to cover shortfalls if a borrower defaults or if the leased equipment sells below its projected residual value. This guarantee performs critical work: it upgrades what would otherwise be speculative-grade paper to investment-grade, materially reducing borrowing costs and making 20 gigawatts of compute financeable. For context, 20 gigawatts roughly equals the combined output of 20 nuclear power plants.
Crucially, these obligations remain off Broadcom’s balance sheet. Nevertheless, S&P Global Ratings classifies the support as a “contingent debt-like obligation,” prompting credit analysts to look beyond the company’s reported leverage metrics. Before accounting for these arrangements, Broadcom carries roughly $64.9 billion in debt against approximately $19.6 billion in cash.
BofA’s Curcuruto performed the calculations that unsettled the market. Scaling the platform to its stated 20-gigawatt ambition projects a senior debt stack of about $370 billion by mid-2029, with roughly $150 billion scheduled for issuance in 2027 alone. However, that $370 billion represents debt owed by the special-purpose vehicles, not Broadcom itself, against which the company has only guaranteed a portion. Bank of America considers the exposure manageable, noting that Broadcom retains concrete remedies: if a lessee defaults, the company can assume the lease or liquidate the hardware to recover much of the shortfall.
Consequently, the bear case does not hinge on an isolated default but on systemic correlation. These guarantees incur minimal cost during periods of robust demand but become simultaneously payable across borrowers, vehicles, and the broader industry only during a sharp, widespread downturn. As CreditSights noted, these structures prove most consequential in “a severe, abrupt downturn.”
Broadcom is not an outlier but rather the clearest example of a financing model rapidly spreading across AI infrastructure. Nvidia (NASDAQ: NVDA) has indicated it will provide residual-value support for up to a quarter of its opportunities, with parallel financing structures reportedly exceeding $500 billion. Meta pioneered similar approaches for data centers through its Beignet ($28 billion) and Sopaipilla ($13 billion) vehicles, while Broadcom’s own Big Sky transaction, which backstops Anthropic, totals approximately $29 billion. Bond traders are currently tracking close to $70 billion in these shadow credit backstops. Moody’s has cautioned that the primary concentration risk stems from multiple deals maturing within a compressed timeframe rather than from any single transaction. DoubleLine portfolio manager Mariya Entina framed the concern more bluntly, arguing that such financial engineering “obscur[es] the financial reality.”
Viewed alongside Alibaba’s discounted $10.2 billion equity raise and Nebius’s $5 billion convertible offering, a clear sequence emerges: the AI buildout has progressed through internal cash, then public equity, then convertible securities, and has now reached the credit markets. Unlike earlier stages, credit markets price downside risk first. Nvidia’s recent market print underscored this shift; demand commentary now carries direct credit consequences alongside traditional earnings impacts. As long as strong guidance sustains utilization, every guarantee remains dormant.
The true test of market appetite lies in whether the roughly $30 billion junior tranche clears. While senior paper wrapped in a Broadcom guarantee will easily find buyers, unwrapped junior risk offers a clearer read on underlying sentiment. Meanwhile, ratings agencies continue to monitor the situation closely. Both S&P and Moody’s have flagged these structures without taking formal action, but a definitive outlook change would move AVGO credit spreads faster than any potential equity downgrade.
