Analysis
Bank of America, Blackstone, Citi and Morgan Stanley are lining up $63 billion in financing for a special-purpose vehicle that will buy Broadcom's AI accelerators and networking gear and lease the equipment to Anthropic, according to a Dow Jones report carried by Morningstar and confirmed independently by Reuters. Broadcom is providing residual-value support equal to the first-lien portion of the debt, a guarantee that keeps the chips' resale value underwritten even if Anthropic's own compute needs change.
The deal lands hours after Anthropic publicly filed its S-1 for an IPO the Wall Street Journal has reported could value the company between $1.5 trillion and $2 trillion. It is also Anthropic's third mega debt arrangement in under two months.
How much debt has Anthropic lined up since September?
- Sep 3, 2026 -- $15 billion, led by Morgan Stanley, Goldman Sachs, JPMorgan and Citigroup.
- Oct 17, 2026 -- $60 billion, led by Blackstone.
- Oct 26, 2026 -- $63 billion, Monday's new Broadcom-equipment lease vehicle from Bank of America, Blackstone, Citi and Morgan Stanley.
That is roughly $138 billion in debt-backed compute financing in under two months, on top of the $65 billion Series H and $30 billion Series G Anthropic raised in equity earlier this year.
Why lease chips through a special-purpose vehicle instead of borrowing directly?
The structure mirrors a pattern spreading across the AI infrastructure complex. Pulse first tracked it in a September financing arrangement tying Broadcom, Nvidia and AMD debt to AI buildouts, and CoreWeave, Oracle and other compute providers have used similar off-balance-sheet leases to fund GPU purchases without carrying the debt directly. The logic repeats each time: a bank-led consortium buys the hardware, holds the lien, and collects lease payments, while the AI company avoids putting tens of billions of dollars of equipment debt on its own books and credit rating.
Anthropic isn't alone in choosing lease-style financing over cash: OpenAI has structured multiyear compute commitments with Oracle and Microsoft running into the hundreds of billions, and xAI leaned on supplier financing before its absorption into SpaceX earlier this year. Broadcom, for its part, has emerged as a preferred custom-chip supplier for several of these buildouts, competing directly with Nvidia's merchant GPUs and Marvell's networking silicon for the same lease-backed dollars.
Anthropic's own numbers put the new financing in perspective. Total venture funding tracked: roughly $111.5 billion. Valuation set in May's Series H: $965 billion. Annualized revenue run rate Pulse has tracked as of Oct. 15: $16.8 billion -- a separate, point-in-time metric from the half-year GAAP revenue the S-1 discloses, not a restatement of it.
The new $63 billion vehicle alone equals more than half of Anthropic's entire tracked equity funding to date -- a sign that capital financing today's frontier AI labs increasingly resembles project financing for a pipeline or a power plant, not a traditional venture round.
For later-stage investors and LPs, the practical point is that an equity mark no longer describes Anthropic's full capital structure. A $965 billion valuation set in May says nothing about the roughly $138 billion in lease and debt obligations layered on since -- obligations that sit ahead of equity in any downside scenario. Anyone pricing a secondary position or sizing a follow-on check in a frontier lab now has to treat SPV commitments as real liabilities against the business, not side arrangements that live outside it.
What the headline misses: Anthropic doesn't own these chips, it leases them, and its own S-1 disclosed that its largest customers can walk away from compute commitments at any time, Fortune reported from the filing. If usage growth slows even modestly, Anthropic is still contractually on the hook for quarterly lease payments on equipment it never owned outright -- the same mismatch between fixed obligations and variable revenue that strained early cloud-computing resellers a decade earlier.
Broadcom's next earnings call will show how much of its backlog now depends on Anthropic continuing to make those lease payments, and whether Bank of America, Blackstone, Citi and Morgan Stanley end up competing with -- or alongside -- the SPV lenders behind SpaceX's own $40 billion GPU financing, struck the same Monday.
