TL;DR
Bank of America, Citi, Morgan Stanley and Blackstone committed financing for a special-purpose company to buy Broadcom AI hardware and lease it to Anthropic, with deliveries due from 2027. Broadcom is backing the senior debt’s residual value, while Anthropic’s filing describes large fixed rent obligations and a possible Broadcom loan facility for rent. The deal’s rates, maturities and detailed financing split have not been disclosed.
Bank of America, Citi, Morgan Stanley and Blackstone have committed financing for a newly formed company that will buy Broadcom AI accelerators and networking equipment and lease them to Anthropic, according to an October 26 joint release. Broadcom will support the value of the equipment against the senior debt, while Anthropic’s filings describe substantial fixed rent commitments—placing the financing, equipment and customer obligations in an interconnected chain.
The new company, a special-purpose vehicle (SPV), will purchase Broadcom hardware and lease it to Anthropic, with deliveries expected from 2027. The release says Bank of America, Citi and Morgan Stanley arranged the first-lien financing; Blackstone is the sole provider of the committed second-lien portion, which ranks behind the first lien for repayment. The firms did not disclose interest rates, maturities or the exact division between the two debt levels.
Broadcom has agreed to provide “residual value support” to the SPV in an amount equivalent to the first-lien financing. Reuters, citing two sources, put that senior debt at about $43.5 billion, or 69% of the total financing. The guarantee is intended to cover a shortfall if equipment is sold for less than the senior debt owed; the public release does not provide its detailed terms.
Anthropic’s registration filing describes related lease obligations of about $161.2 billion over five years, excluding interest. It says rent is payable quarterly once equipment is ready for service, or earlier if a data-centre delay triggers payment, and that the leases generally cannot be cancelled except on default. The filing also says Anthropic may issue up to $42 billion in convertible notes to Broadcom, solely to finance quarterly rent, at 9% interest paid in kind. The filing does not establish that this possible rent financing is part of the newly announced SPV arrangement.

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 arrangement lets Anthropic obtain computing capacity without paying the full hardware cost upfront, while the SPV raises money from outside lenders to purchase the equipment. Broadcom benefits from a funded sale of its chips, but its residual-value support leaves it exposed if the hardware is worth less than the senior debt when lenders seek repayment. Blackstone’s second lien is structurally behind the senior lenders, meaning the positions do not carry identical repayment priority.
The tension is between fixed lease costs and revenue that can vary with customer demand. Anthropic’s filing says about 80% of its revenue comes from metered usage. That does not establish that Anthropic will struggle to pay, but it makes utilization and customer demand relevant to the ability to meet long-term rent commitments. If usage grows more slowly than projected, the financing chain could face pressure; the precise losses would depend on contract terms, equipment resale value and available cash.
The proposed Broadcom notes could help cover rent in some circumstances, but they are not cost-free relief: the filing specifies 9% interest paid in kind, and says access may become more expensive if revenue conditions are missed. After an uncured default, Anthropic “may not be permitted” to use the facility. These are terms described in Anthropic’s filing, not evidence that a default is expected.

Earlier Financing Sets a Precedent
The October transaction follows a separate $35 billion compute financing announced in June by Broadcom, Apollo and Blackstone’s credit and insurance business. Broadcom said that programme was designed to support more than 20 gigawatts of compute for frontier AI labs, including Anthropic and OpenAI, through 2028. Its first tranche, led by Apollo, was intended to fund more than one gigawatt for Anthropic at Fluidstack sites.
Broadcom’s quarterly filing described a backstop for that earlier lease structure. If a customer defaults, Broadcom may have to cover the difference between 85% of the remaining amount owed and the proceeds from selling the equipment. Broadcom estimated its maximum exposure at about $29 billion once all racks are deployed, undiscounted. It said the guarantee’s fair value was not material and that no payment had been made as of the quarter ended August 2, 2026. Those disclosures concern the earlier arrangement and should not be treated as the final terms of the new $63 billion deal.
The new release presents a similar broad structure—outside financing buys Broadcom hardware for customer use, with Broadcom supporting residual value—but does not identify all detailed contractual links. Anthropic’s filing says a March 2026 Broadcom lease was intended for assignment to a designated financial partner and that part of a lease had already been assigned to a third party. The available documents do not confirm that the newly announced SPV is the same financial partner.
“A default in this kind of contract chain “could set off a cascading series of adverse consequences.””

Terms and Exposure Still Undisclosed
The joint release does not state the new facility’s interest rates, maturities or exact lien amounts. The estimate that senior debt is about $43.5 billion comes from sources cited by Reuters, rather than figures in the release. The public materials also do not set out all conditions, limits or enforcement details for Broadcom’s residual-value support.
It is also unclear whether Anthropic’s possible $42 billion of convertible notes to Broadcom will be used, how much Anthropic might borrow for rent, or whether that facility connects directly to this SPV. The relationship between the SPV and the financial partner referenced in Anthropic’s filing is not confirmed. A Wall Street Journal account, reported by Benzinga, said some banks considered withdrawing before Broadcom agreed to higher rates and additional loss protection; that account rests on a single report and is not independently established by the deal release.
There is no disclosed evidence that Anthropic has missed a payment or that lenders have suffered a loss. The eventual exposure will depend on deployment, lease performance, equipment resale values and the detailed contracts, several of which are not public.
Watch Deliveries and Lease Terms
The next visible milestone is the planned start of equipment deliveries in 2027. Investors and customers will be able to assess the arrangement more clearly as deployments begin and the companies disclose further information about lease assignments, financing costs or guarantees. Anthropic’s filings and Broadcom’s periodic reports may provide updates on lease commitments and contingent exposure.
For now, the announced commitments describe a financing structure, not proof that the full amount has been drawn or that all planned equipment is operating. Further disclosures would be needed to establish the final debt split, the precise scope of Broadcom’s support and whether Anthropic uses the possible rent-note facility.

What does Broadcom’s guarantee cover?
Broadcom has promised residual-value support equal to the first-lien amount. The broad purpose is to protect the SPV if equipment resale proceeds fall short, but the release does not publish the detailed terms.
Will Broadcom also lend Anthropic money for rent?
Anthropic’s filing says it may issue up to $42 billion in convertible notes to Broadcom for quarterly rent, at 9% interest paid in kind. The filing does not say that the full amount will be issued or confirm that the facility is part of this newly announced SPV financing.
Has Anthropic defaulted on the leases?
No default is reported in the supplied materials. Anthropic’s filing discusses possible consequences of default as a contractual risk, not as an event that has happened.
