Broadcom AI Debt Backstops Push Credit Risk to a Record

Broadcom’s (NASDAQ: AVGO) AI debt backstops have pushed the company’s credit default swaps to a record 122 basis points, and bond investors — not equity investors — are now setting the terms of the debate. The spike followed Broadcom’s August 20 move to arrange as much as $100 billion through off-balance-sheet vehicles that buy AI chips and lease them to customers. Bank of America, meanwhile, estimates the platform could carry $370 billion in senior debt by mid-2029.

Key Points

• Credit signal: Broadcom CDS hit a record 122 basis points after the August 20 announcement, and BofA flags bond spreads 20 to 45 basis points wider than industry peers.
• Deal size: $60–70 billion of senior secured debt plus a roughly $30 billion junior tranche — up to about $100 billion in total, raised through a special-purpose vehicle rather than on Broadcom’s balance sheet.
• The structure: The SPV buys custom AI chips and leases them to customers including Anthropic. Broadcom guarantees a portion of the senior tranche, which secures investment-grade ratings and lower borrowing costs.
• The long number: BofA’s Tom Curcuruto estimates the vehicle could reach $370 billion in senior debt by mid-2029, with roughly $150 billion of new issuance in 2027 alone.
• Precedent: June’s $35 billion AI XPV deal, led by Apollo (NYSE: APO) and Blackstone (NYSE: BX), funded more than 1 gigawatt of compute. The new platform targets 20-plus gigawatts through 2028.
• Stock reaction: AVGO fell more than 5% Friday and closed the week down 6.2% at $368.45.

What Broadcom Is Actually Guaranteeing

The mechanics matter more than the headline number, so start there.

A special-purpose vehicle borrows money and buys chips. It then leases those chips to an AI company — Anthropic, in the anchor transaction. Broadcom does not borrow the money itself. Instead, it backstops a slice of the senior debt, promising to cover shortfalls if the borrower defaults or if the equipment sells below its expected residual value.

That guarantee does real work. It converts what would otherwise be speculative-grade paper into investment-grade paper, which cuts the borrowing cost materially and makes 20 gigawatts of compute financeable in the first place. For scale, 20 gigawatts roughly equals the output of 20 nuclear plants.

Crucially, the obligation sits off Broadcom’s balance sheet. S&P nonetheless treats the support as a “contingent debt-like obligation” — which is precisely why credit analysts have stopped reading the reported leverage at face value. Broadcom carries roughly $64.9 billion of debt against about $19.6 billion of cash before counting any of this.

The $370 Billion Question

BofA’s Curcuruto did the arithmetic that unsettled the market. Scale the platform to its stated 20-gigawatt ambition, and the senior debt stack reaches about $370 billion by mid-2029, with roughly $150 billion issued in 2027 alone.

However, that $370 billion is not money Broadcom owes. It is debt the vehicle owes, against which Broadcom has guaranteed a portion. BofA itself calls the exposure manageable, and the company retains real remedies: if a lessee defaults, Broadcom can assume the lease or sell the hardware, recovering much of the shortfall.

The bear case, therefore, does not rest on any single default. It rests on correlation. These guarantees cost nothing while demand runs hot. They come due simultaneously — across borrowers, across vehicles, across the industry — only in a sharp, broad downturn. As CreditSights put it, the structures matter most in “a severe, abrupt downturn.”

The Industry-Wide Pattern

Broadcom is not an outlier. It is the clearest example of a structure now spreading across AI infrastructure finance.

Nvidia (NASDAQ: NVDA) has signaled residual-value support for up to a quarter of its opportunities, and its parallel financing structure reportedly exceeds $500 billion. Meta, meanwhile, pioneered the approach for data centers through its Beignet ($28 billion) and Sopaipilla ($13 billion) vehicles. Broadcom’s own Big Sky transaction, which backstops Anthropic, runs to roughly $29 billion.

Bond traders now track something close to $70 billion of these shadow credit backstops. Moody’s has warned that the concentration risk comes from many such deals landing in a short window rather than from any one of them. DoubleLine portfolio manager Mariya Entina framed the objection more bluntly, arguing that financial engineering “obscur[es] the financial reality.”

Read alongside Alibaba’s discounted $10.2 billion equity raise and Nebius’s $5 billion convertible, a sequence emerges. The AI buildout has worked through cash, then equity, then converts. Now it has reached the credit markets — and credit markets price downside first.

What to Watch Next

Nvidia’s print Wednesday. Demand commentary now carries credit consequences, not just earnings consequences. Strong guidance keeps every guarantee dormant.

Whether the junior tranche clears. The roughly $30 billion junior piece is the real test of appetite. Senior paper wrapped in a Broadcom guarantee will find buyers; unwrapped junior risk is a cleaner read on sentiment.

Ratings agency language. S&P and Moody’s have flagged the structures without acting on them. A formal outlook change would move AVGO spreads faster than any equity downgrade.
