TL;DR
Bank of America, Citi, Morgan Stanley and Blackstone have committed financing for a special-purpose company to 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’s filing describes substantial fixed lease payments and a possible Broadcom loan facility for rent.
Bank of America, Citi, Morgan Stanley and Blackstone have committed $63 billion to a newly formed company that will buy Broadcom AI accelerators and networking equipment and lease them to Anthropic, according to a joint announcement on October 26. Broadcom will support the value of the hardware backing the senior loans, linking the chip supplier to the financing risk as well as the sale.
The financing is structured through a special-purpose vehicle (SPV). The vehicle will borrow from the participating lenders, purchase Broadcom equipment and lease it to Anthropic. Bank of America, Citi and Morgan Stanley are arranging the first-lien debt; Blackstone is the sole provider of the committed portion of the second lien, which ranks behind the senior borrowing. The announcement did not disclose interest rates, maturities or the allocation of the $63 billion between the two layers.
Broadcom has agreed to provide residual-value support to the SPV equal to the amount of the first-lien financing. Reuters, citing two sources, put that senior amount at about $43.5 billion, or 69% of the total commitment. The support is intended to cover a shortfall if equipment has to be sold for less than the senior debt owed. It is not the same as a disclosed guarantee of every payment Anthropic owes, and the public announcement does not provide the detailed terms.
Anthropic’s S-1 filing describes related lease arrangements with about $161.2 billion in rent over five years, excluding interest, and says the leases generally cannot be cancelled except in default. That figure covers the Broadcom leases described in the filing; the announcement does not establish that every dollar belongs to this newly announced SPV. The filing also says Anthropic may issue up to $42 billion in convertible notes to Broadcom solely to fund quarterly rent, at 9% interest paid in kind. The precise connection between that facility and Monday’s financing was not confirmed in the announcement.

Who Bears the Hardware Risk
The structure allows Anthropic to secure large quantities of specialized computing equipment without paying the full purchase price upfront. The lenders provide capital to the SPV, and the SPV pays Broadcom for the hardware; Anthropic then makes lease payments as the equipment becomes available for service. That arrangement can support infrastructure expansion while shifting the initial purchase funding away from Anthropic’s direct cash outlay.
It also creates exposures across several parties. Anthropic owes rent under long-term leases, the SPV relies on those payments to service its debt, and Broadcom’s residual-value support could be called on if equipment resale proceeds fall short of senior obligations. Blackstone’s second-lien position is subordinate to the first lien, so it carries a different repayment position. The public materials do not spell out all remedies, caps or conditions, making it difficult to calculate each party’s ultimate loss in a default scenario.
The arrangement matters because the economics depend on future AI demand and usage, while significant costs are fixed in advance. Anthropic’s filing says 80% of its revenue is metered usage, meaning revenue depends substantially on how much customers use its services. That does not establish that Anthropic will miss payments, but it highlights the gap between variable revenue and long-term lease obligations. The filing warns that a default in this kind of contract chain could trigger “a cascading series of adverse consequences.”

Earlier Anthropic Compute Financing
The October transaction follows a separate $35 billion financing announced in June for Anthropic compute at Fluidstack sites. Broadcom said that arrangement was part of 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 labs, including Anthropic and OpenAI, through 2028. Broadcom’s quarterly filing described a backstop for that earlier lease structure, with maximum exposure of approximately $29 billion once all racks were deployed.
That earlier backstop is a separate disclosed arrangement and should not be treated as the terms of the new $63 billion package. Broadcom reported that the fair value of the earlier promise was “not material” and said it had made no payments under it as of the quarter ended August 2, 2026. The company described such guarantees as contingent liabilities it believed had a low probability of occurring, citing the profitability trajectory of leading frontier AI labs.
Anthropic’s S-1 says a March 2026 Broadcom lease was one under which Broadcom intended to assign the lease to a designated financial partner, and that part of a lease had already been assigned to a third party in the second quarter. The new SPV may fit that description, but neither the announcement nor the filing confirms the link. A report by the Wall Street Journal, as relayed by Benzinga, said some banks considered leaving the project as rates rose and that Broadcom CEO Hock Tan agreed to higher rates and gave lenders more comfort on loss guarantees during weekend talks. That account rests on a single report and has not been detailed in the joint announcement.
““[The deal] validates that there is capital available to finance such growth and that Broadcom is uniquely positioned to enable it.””

Terms and Default Exposure Still Open
The joint announcement does not provide the interest rates, loan maturities, lien amounts or full guarantee terms. Reuters’ estimate of roughly $43.5 billion for first-lien debt is based on two sources, not a figure disclosed in the release. The announcement also does not say what happens to the equipment, lease or debt under specific default scenarios.
It remains unclear whether the new SPV is the financial partner referenced in Anthropic’s S-1, and whether the possible $42 billion Broadcom note facility applies to rent under this specific transaction. The filing says access to rent financing may become more expensive if revenue conditions are missed and may not be permitted after an uncured default. The details of those conditions and their application here are not established by the deal announcement.
The scale of the commitments does not by itself show that a loss will occur or that Anthropic cannot meet its obligations. Actual outcomes will depend on equipment deployment, lease payments, resale values, financing terms and demand for Anthropic’s services. The source materials do not provide a consolidated risk calculation across all parties.
Deliveries and Financing Terms Ahead
According to the joint announcement, equipment deliveries are expected to begin in 2027. Further disclosures may clarify the SPV’s final borrowing, the division between first- and second-lien financing, and the terms of Broadcom’s residual-value support. Anthropic’s future filings may also provide updates on lease assignments, rent financing and the conditions attached to its obligations.
Readers will be able to judge how the financing performs as equipment enters service and rent payments begin. Relevant indicators include whether deployment proceeds on schedule, how Anthropic’s usage-based revenue develops, and whether Broadcom reports any payments or changes in its contingent exposure. None of those outcomes is established by the announcement alone.
Key Questions
Who is providing the $63 billion financing?
Bank of America, Citi and Morgan Stanley are arranging the first-lien financing, while Blackstone is the sole provider of the committed portion of the second lien, according to the joint announcement.
What does Broadcom contribute to the deal?
Broadcom is selling accelerators and networking equipment to the SPV and providing residual-value support equal to the first-lien amount. The announced materials do not disclose all terms or establish that Broadcom guarantees every Anthropic lease payment.
How does Anthropic fit into the structure?
The SPV is expected to lease the equipment to Anthropic, which will pay rent. Anthropic’s S-1 describes substantial Broadcom-related lease obligations and a possible note facility for rent, but the public deal announcement does not confirm how those arrangements map onto this SPV.
Does the $63 billion commitment mean a loss is expected?
No. A financing commitment is not evidence that a default or loss will occur. The risk depends on payments, equipment resale values and other contract terms that have not been fully disclosed. Large AI infrastructure investments carry uncertainty, and the reported figures are not a guarantee of future performance.
