TL;DR
Bank of America, Citi, Morgan Stanley and Blackstone committed financing for a special-purpose company that will buy Broadcom AI accelerators and lease them to Anthropic, with deliveries expected from 2027. Broadcom is providing residual-value support for the senior debt, while Anthropic filings describe large fixed lease payments and a possible Broadcom loan facility for rent. The release does not disclose rates or maturities, and the exact allocation of financing and risk is not fully public.
Bank of America, Citi, Morgan Stanley and Blackstone have committed financing for a new company that will buy Broadcom AI accelerators and networking equipment and lease them to Anthropic, according to an October 26 joint release. The deal sets up a large, multi-party funding structure for Anthropic’s computing capacity, with Broadcom providing residual-value support for the senior debt; the announced release does not disclose interest rates, maturities or the full split between the loans.
The special-purpose vehicle, or SPV, is to use the financing to purchase Broadcom hardware and lease it to Anthropic, with deliveries expected to begin in 2027. Bank of America, Citi and Morgan Stanley are arranging the first-lien financing. Blackstone is the sole provider of the committed second-lien portion, which ranks behind the first lien in repayment priority, the release says.
Broadcom said it will provide support to the SPV for an amount equivalent to the first-lien portion. Reuters, citing two sources, put that senior debt at about $43.5 billion, or roughly 69% of the stated $63 billion financing. The release itself does not identify that figure or give a detailed breakdown of the total. Broadcom Chief Executive Hock Tan said the arrangement “validates that there is capital available to finance such growth and that Broadcom is uniquely positioned to enable it.”
Anthropic’s registration filing describes leases with Broadcom totaling about $161.2 billion in rent over five years, excluding interest, and says the leases generally cannot be cancelled except in default. It also says Anthropic may issue as much as $42 billion in convertible notes to Broadcom, at 9% interest paid in kind, solely to finance quarterly rent obligations. These are filing disclosures; the announcement does not specify how much of that possible facility, if any, will be used for this new SPV.

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.

How the Financing Shifts Risk
The structure lets Anthropic secure substantial computing equipment without paying the full purchase price up front. The SPV borrows from outside lenders, buys the hardware from Broadcom and collects rent from Anthropic. That arrangement can support capacity expansion while distributing financing across lenders and the chip supplier rather than placing the entire initial cost on Anthropic.
But the parties’ exposures are linked. Anthropic’s rent is a revenue obligation, while the SPV’s ability to repay lenders depends on rent payments and, in a default scenario, the value of the equipment. Broadcom’s support is intended to cover a shortfall against the senior debt if hardware resale proceeds are insufficient. The precise trigger, limits and other terms for this new support were not included in the joint release.
Anthropic’s filing says about 80% of its revenue comes from metered usage, while its lease payments are fixed. That contrast matters if demand or revenue grows more slowly than planned: costs under the lease may remain due even if usage-based receipts weaken. The filing also warns that a default in this type of contract chain could have “a cascading series of adverse consequences.” That is a disclosed risk, not evidence that a default is expected.

Earlier Anthropic Compute Financing
The October arrangement follows a separate financing announced in June 2026. Broadcom said it had launched an AI infrastructure platform with Apollo and Blackstone’s credit and insurance business, intended to support more than 20 gigawatts of compute for frontier AI companies through 2028. Its first $35 billion tranche was described as funding more than one gigawatt for Anthropic at Fluidstack sites.
Broadcom’s quarterly filing said its maximum exposure under the guarantee tied to that earlier lease could reach about $29 billion once all racks were deployed, on an undiscounted basis. Broadcom said the fair value of the promise was not material and that it had made no payments under it as of the quarter ended August 2, 2026. Those disclosures concern the earlier arrangement and should not be treated as terms of the new SPV deal.
Anthropic’s filing describes Broadcom leases and assignments to financial partners, but it does not explicitly identify the new SPV as the designated partner discussed in the filing. The connection is plausible based on the described structure, but has not been confirmed in the cited announcement or filing.
““Validates that there is capital available to finance such growth and that Broadcom is uniquely positioned to enable it.””
— Broadcom CEO Hock Tan, in the joint announcement
Terms and Exposure Still Undisclosed
The joint release does not state the interest rates, loan maturities, lien amounts or detailed repayment terms. The approximately $43.5 billion senior-debt figure comes from Reuters’ sources, not the release. The announcement also does not explain the full conditions, duration or calculation of Broadcom’s residual-value support.
It is not clear how much, if any, of Anthropic’s potential $42 billion convertible-note facility will fund rent connected with this transaction. The filing describes the facility as available for quarterly rent obligations, but does not establish that it will be drawn for the new SPV. The parties have not publicly confirmed whether this SPV is the financial partner referenced in Anthropic’s filing.
A Wall Street Journal account, reported by Benzinga, said some banks considered withdrawing from the project as rates rose and that weekend talks included higher rates and stronger loss protections. That account is based on a single report; the parties’ public release does not confirm it. The extent of any final changes to terms is not public.
Watch for Lease and Debt Filings
The next points to watch are the equipment delivery schedule, the SPV’s final financing terms and any further disclosures from Anthropic or Broadcom about the lease guarantees and rent funding. The announced plan puts deliveries from 2027, but the release does not give a detailed deployment calendar.
Future company filings may clarify whether the SPV is the designated financial partner described in Anthropic’s registration statement, how much debt each lender provides, and whether Anthropic uses the possible convertible-note facility. Until those details are published, the $63 billion headline describes a financing commitment, not a fully disclosed account of who ultimately bears each cost under different demand or default scenarios.
