Four banks and an asset manager put up $63 billion so that one chip supplier can rent its hardware to one customer. That is the short version of the deal announced on Monday by Bank of America, Blackstone, Citi and Morgan Stanley. The longer version matters more: the supplier guarantees the value of the hardware it sells, it may lend the customer the money for the rent, and the customer’s own filing warns that a default in this kind of contract chain “could set off a cascading series of adverse consequences”. Here is who lends to whom, what secures the money, and who carries the risk if AI usage grows more slowly than planned.

Key takeaways

  • A special-purpose vehicle buys the chips, Anthropic rents them. The $63 billion goes into a newly formed company that buys Broadcom accelerators and networking gear and leases them to Anthropic, with deliveries from 2027 (joint release, October 26, 2026).
  • Broadcom backs the senior debt. It provides “residual value support” equal to the first-lien loans, which two sources put at about $43.5 billion, or 69% (Reuters). Blackstone provides the committed second lien, which ranks below.
  • It is the second deal of this kind. In June, Apollo and Blackstone financed $35 billion of Anthropic compute, and Broadcom backstopped up to about $29 billion of the lease (Broadcom 10-Q).
  • Broadcom can also lend Anthropic the rent. Anthropic may issue up to $42 billion of convertible notes to Broadcom “solely to finance quarterly rent obligations”, at 9% interest paid in kind (Anthropic S-1, p. 166).
  • The rent is fixed, the revenue is not. Anthropic’s Broadcom leases total about $161.2 billion of rent over five years, excluding interest, and cannot be cancelled except on default (p. 171). 80% of its revenue is metered usage (p. 138).
  • The safety net thins when it is needed. If Anthropic misses revenue conditions, the rent loans get more expensive; after an uncured default it “may not be permitted” to use them at all (pp. 74, 166–167).

The deal in one paragraph

According to the release, the “Lead Financial Partners” committed financing to a newly formed special-purpose vehicle (SPV). The SPV buys “Broadcom XPU AI accelerators and networking solutions to be leased to Anthropic”. Bank of America, Citi and Morgan Stanley arrange the first lien; Blackstone is “the sole provider of the committed portion of the second lien”. Broadcom provides “residual value support to the SPV for the amount equivalent to the first lien portion”. The release gives no interest rates, maturities or split between the liens, and Anthropic is not quoted. Broadcom’s CEO Hock Tan said the deal “validates that there is capital available to finance such growth and that Broadcom is uniquely positioned to enable it.” That is his claim, and it is also the sales pitch: Broadcom sells more chips when someone else pays for them up front.

The deal nearly stalled. According to the Wall Street Journal, as reported by Benzinga, some banks considered walking away from “Project North Star” as rates rose, until Tan agreed to higher interest rates in weekend talks and gave more comfort on the loss guarantees. That account rests on a single report.

Who lends to whom

The machine has five moving parts. The money flows in a loop, which is why “circular” is the word critics use. It is not fully circular, though: real outside money from banks and Blackstone enters at the top.

  1. Lenders to the SPV. The three banks lend the senior, first-lien money; Blackstone lends the second lien, which is repaid only after the first.
  2. SPV to Broadcom. The SPV pays Broadcom for the hardware. For Broadcom this is a sale.
  3. SPV to Anthropic. The SPV leases the equipment to Anthropic. In the S-1, Anthropic’s side runs through “two special purpose subsidiaries”, guaranteed by Anthropic, PBC, with the obligations “secured by the leased equipment” (p. 172).
  4. Anthropic back to the SPV. Anthropic pays rent quarterly, starting when equipment is “ready for service”, or earlier if a data center is delayed (p. 171). The rent services the loans.
  5. Broadcom behind the lenders. If the hardware is worth less than the senior debt when it has to be sold, Broadcom covers the gap up to the first-lien amount.

Is this SPV the one the S-1 describes? The filing says the March 2026 Broadcom lease is one “under which Broadcom intends to assign to a designated financial partner” (p. 57), and that Broadcom already assigned part of one lease to a third party in the second quarter (p. 172). The new SPV fits that description. Neither the release nor the filing confirms the link, so treat it as my reading.

Whether this SPV is the “designated financial partner” to which Broadcom “intends to assign” the March 2026 lease (S-1 p. 57) is our reading; neither the release nor the filing says so.

The first loop: $35 billion and a $29 billion backstop

The June deal shows how Broadcom prices its own risk. On June 9, Broadcom launched an “AI XPV Platform” with Apollo and Blackstone’s credit and insurance business, designed for “more than 20 gigawatts” of compute for frontier labs “including Anthropic and OpenAI” through 2028. The first tranche of $35 billion, led by Apollo, funds more than one gigawatt for Anthropic at Fluidstack sites (Broadcom, June 9, 2026).

Broadcom’s quarterly report spells out the backstop. If the customer defaults on its five-year lease, Broadcom pays the difference between 85% of what is still owed and what the racks fetch when sold. Its maximum exposure, once all racks are deployed, is “approximately $29 billion” undiscounted. The fair value of that promise “was not material” and nothing has been paid (10-Q, quarter to August 2, 2026). Broadcom calls such guarantees “contingent liabilities we believe would have a low probability of occurring, supported by the strong profitability trajectory of the leading frontier AI labs”. That is Broadcom’s own judgment of its customer.

The same filing describes the platform’s purpose with unusual frankness: it “bridges the gap between the current cash flows of the leading frontier AI labs and significant upfront investments required for their businesses.”

Layers of risk: senior banks backed by Broadcom, Blackstone's second lien below them, and Broadcom's guarantees behind both.

Broadcom wears three hats

Put the filings side by side and Broadcom shows up three times in the same chain:

  • Seller. It sells the accelerators and networking gear to the SPVs.
  • Guarantor. It backs the lenders: up to about $29 billion in the June deal, and the first-lien amount, reported at about $43.5 billion, in the October deal.
  • Potential lender to the rent. Under the “Infrastructure Partner 2026 NPA”, Anthropic may issue up to $42 billion of notes to Broadcom, or to a financial partner Broadcom assigns them to. Interest is 9% a year, paid in kind, meaning it is added to the principal. Holders can convert into non-voting Class N shares at 90% of the 30-day average share price. On a change of control they can demand 150% of principal and interest in cash (pp. 166–167). Broadcom’s 10-Q confirms the $42 billion and that no notes had been issued by August 2.

If both guarantees peaked at the same time, they would add up to about $72.5 billion, by my arithmetic. Broadcom’s own debt principal was $61.1 billion on August 2. The two numbers are not the same kind of thing: guarantees shrink as rent is paid and only cost money after a default and a weak resale. But they show why Moody’s, which calls Broadcom one of the strongest large technology companies, warned that risk would increase “if multiple transactions were undertaken over a short period”. The Journal also reports Broadcom is seeking more than $50 billion to finance chips for OpenAI, which again is a single report.

The turn: what happens if usage slows

Here is the part the press release does not discuss. The S-1 describes a mismatch in plain words: “our revenue is primarily consumption-based, and much of it is not subject to long-term contractual commitments, while our compute and infrastructure commitments generally extend over multiple years” (p. 32). Some agreements are take-or-pay: they “obligate us to pay for resources regardless of actual utilization” (pp. 31–32). The Broadcom leases are “non-cancelable by either party” except on default (pp. 171–172).

Now walk through a slowdown. Today Anthropic looks comfortable: $16.3 billion of revenue in the first half of 2026, up from $1.2 billion a year earlier (p. 147), $3.9 billion of operating cash flow (p. 168), and $131.7 billion of cash and short-term investments (p. 172). Anthropic also says it is “not dependent” on the Broadcom notes (p. 74). If growth slows sharply, three things happen in sequence:

  1. The rent loan gets dearer. Notes issued while “certain revenue performance conditions are not met” bear 13% instead of 9% and convert at 85% instead of 90% of the share price (p. 166). The conditions are set “significantly below” Anthropic’s growth so far (pp. 166–167).
  2. The rent loan can disappear. The right to issue notes “terminates if these conditions are not met for a sustained period”, and depends on keeping $5 billion of minimum liquidity under the credit facility (pp. 163, 167). After an uncured payment or performance default, much of the lease is accelerated and Anthropic “may not be permitted” to use the notes to pay it (p. 74). The backstop is weakest exactly when it would be needed.
  3. Defaults travel. A default under “certain commercial agreements could trigger cross-default provisions” in the credit facility and some convertible notes, “potentially resulting in the acceleration of substantially all” of its debt (p. 32). The Broadcom notes also have cross-defaults to material debt (p. 167).

Who loses first? Inside the SPV, the senior banks have Broadcom’s support up to their full amount. Blackstone’s second lien sits below them and carries more of the risk that the chips lose value faster than the lease pays them down. Then Broadcom pays the shortfall, minus what the hardware fetches. Anthropic’s filing adds one more risk: financing tied to “exclusive or preferential supply commitments” with particular chip suppliers may leave it on “platforms that are suboptimal” if technology moves on (p. 32). This is my reading of the documents; the actual loan agreements are not public.

The turn

What happens if AI usage grows more slowly than the rent

The rent is fixed for five years; most of the revenue is metered. Here is how the safety net behaves in a slowdown, and who absorbs a loss.

If revenue slows: the sequence

From Anthropic’s S-1. Page numbers in brackets.

  1. Today

    $16.3B revenue in H1 2026, up from $1.2B (p. 147); $3.9B operating cash flow (p. 168); $131.7B cash and short-term investments (p. 172). Anthropic says it is "not dependent" on the Broadcom notes (p. 74).

  2. Fixed side

    Broadcom leases ~$161.2B over 5 years, "non-cancelable" except on default (pp. 171–172). Take-or-pay terms "regardless of actual utilization" (pp. 31–32).

  3. Variable side

    80% of revenue is metered consumption (p. 138); "much of it is not subject to long-term contractual commitments" (p. 32).

  4. Step 1 · dearer

    Notes issued while revenue conditions are missed: 13% instead of 9%, conversion at 85% instead of 90% of the share price (p. 166).

  5. Step 2 · gone

    The right to issue notes "terminates" if conditions fail "for a sustained period"; needs $5B minimum liquidity (pp. 163, 167). After an uncured default the lease accelerates and the notes "may not be permitted" (p. 74).

  6. Step 3 · contagion

    Cross-defaults could mean "acceleration of substantially all" debt and "a cascading series of adverse consequences" (p. 32).

Who loses first inside the SPV

Second-lien size = $63B minus the reported first lien (our arithmetic). The release gives no split.

First lien · banks · backed by Broadcom~$43.5B
Second lien · Blackstone~$19.5B
Behind both: Broadcom pays the shortfall after a resalecontingent

The senior banks are backed by Broadcom up to their full amount. Blackstone sits below and carries more of the risk that the chips lose value faster than the lease pays them down. This is our reading; the loan agreements are not public.

The S-1 also flags that financing tied to “exclusive or preferential supply commitments” may leave Anthropic on “platforms that are suboptimal” if technology moves on (p. 32).

How it compares

The same week brought three other answers to the same question: how do you pay for AI hardware?

DealSizeStructureWho carries the risk
Broadcom / Anthropic (Oct 26)$63BSPV buys Broadcom chips, leases to AnthropicBanks first lien, Blackstone second lien, Broadcom residual value support
SpaceX / Apollo (Oct 26)~$40BApollo-managed entity buys GPUs, leases to SpaceX for about 5 to 5.25 yearsLessor; SpaceX as lessee, no chipmaker guarantee reported
Broadcom XPV tranche (Jun 9)$35BApollo and Blackstone fund racks leased to AnthropicLenders; Broadcom backstop up to ~$29B
CoreWeave DDTL 4.0 (Mar 30)$8.5BLoan secured by one GPU subsidiary’s assets and a customer contractLenders; rated A3 by Moody’s
Meta financing plan (Oct 26)~$95BNew stock: ~$35B now, ~$60B at-the-market from 2027Shareholders, no collateral

Sources: TechCrunch and CNBC on SpaceX’s filing (Elon Musk said “closed”; the filing calls it a binding commitment expected to close by year-end); CoreWeave, March 30, 2026; Meta’s free writing prospectus, which we covered in 60,000 Buyout Offers and a $95 Billion Stock Sale.

The pattern: the hardware moves off the lab’s balance sheet into a separate vehicle, and the chip itself becomes the collateral. What differs is who stands behind it. SpaceX leans on its own credit, CoreWeave on a customer contract, Meta on its shareholders. Anthropic leans on its supplier. Oracle shows what a strained tenant looks like: in September it sent a force majeure notice to the developer of a delayed New Mexico data center, and its bonds due 2055 traded at 77 cents on the dollar, according to PitchBook data (Axios, September 25, 2026).

What this means for companies

For companies: price caps, exit rights and change-of-control terms matter more when your AI supplier is heavily leveraged.
  • Your AI vendor’s financing is now part of your vendor risk. Anthropic’s filing says Broadcom “may prioritize the supply of AI accelerators” to other customers or “alter the terms of our equipment lease” (p. 74). A supplier that is both landlord and creditor has leverage over capacity. Ask your providers where their compute comes from and how concentrated it is.
  • Price stability depends on the rent. Fixed lease payments for five years push a provider to fill capacity, which can mean aggressive discounts now. If revenue lags, the same rent can push prices up or cut free tiers later. Lock in price caps for the term you need; our AI price war piece covers the fine print.
  • Read the change-of-control and termination clauses. The Broadcom notes pay 150% in cash on a change of control. For a customer, the question is what happens to your contract, your data and your service levels if a heavily leveraged supplier is sold or restructured. Insist on data portability, exit rights and a tested second model provider.
  • Do not mistake headlines for capacity. Deliveries for this deal start in 2027. The S-1 warns that multi-party chains can mean “significant cash outflows without obtaining usable compute on a timely basis” (p. 75). Plan for delays.

What this means for users

This section is informational only and not investment advice.

  • The money may be yours. Blackstone’s June role ran through its “credit and insurance business”, and CoreWeave’s loan included “insurance investors” (Broadcom, June 9; CoreWeave). In the release, Citi cites its “distribution expertise” and Bank of America its ability to “mobilize institutional capital at scale”. Pension funds, annuities and insurance policies can end up holding AI chip debt without savers ever choosing it.
  • The product you use is financed on a five-year clock. If you rely on Claude or any other model for work, the provider’s cost of capital shapes prices, limits and how long a model stays available.
  • The S-1 is the best map. Anthropic’s prospectus discloses these terms in more detail than most private deals. Read the pages cited here before trusting a headline, including this one.

Honest limits

The SPV’s loan agreements, interest rates, maturities and the split between the liens are not public. The $43.5 billion first-lien figure comes from two unnamed sources cited by Reuters. The bank jitters and the OpenAI financing come from one Wall Street Journal report, read via Benzinga. Broadcom’s investor page carries an infographic on the deal that I could not access, so its numbers are not used here. The S-1 figures are as of June 30, 2026, and several of them are blank in the filing. Whether the new SPV is the “designated financial partner” named in the S-1 is my inference. Broadcom did not respond to Reuters, and Anthropic was not quoted in the release. For the wider picture, read our critical reading of the S-1, the overview of Anthropic’s IPO filing and AI Pays Off Almost Nowhere Outside Tech.
