TL;DR
Banks and Blackstone committed financing for a special-purpose company to buy Broadcom accelerators and lease them to Anthropic, with deliveries expected from 2027. Broadcom is providing hardware-value support for the senior debt, while Anthropic’s filing describes large, fixed lease obligations and a possible rent-financing facility from Broadcom. Rates, maturities and the precise allocation of risk have not been disclosed.
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. The structure, announced October 26, puts outside lenders behind the hardware purchase while Broadcom provides support for the value of the equipment; Anthropic’s filing describes substantial lease payments and a possible separate loan facility to help pay rent.
Under the deal announcement, the new special-purpose vehicle (SPV) will purchase Broadcom XPU accelerators and networking solutions, then lease the equipment to Anthropic. Bank of America, Citi and Morgan Stanley are arranging the first-lien loans, which rank ahead of other borrowing against the SPV. Blackstone is the sole provider of the committed portion of the second lien, which would be repaid after the senior debt.
Broadcom is providing residual-value support to the SPV for an amount equivalent to the first-lien financing. Reuters put that senior amount at about $43.5 billion, or 69% of the total. The public deal announcement does not provide the interest rates, loan maturities or a full breakdown of the financing, so the exact terms cannot yet be established from the disclosed material.
The equipment is expected to be delivered from 2027, according to the joint release. Anthropic’s filing says its Broadcom leases total about $161.2 billion in rent over five years, excluding interest, and generally cannot be cancelled except in default. It also describes up to $42 billion in convertible notes from Broadcom that Anthropic may issue solely to finance quarterly rent obligations, with interest paid in kind at 9%. The filing describes those potential notes; it does not establish that Anthropic has issued the full amount.

Who Carries the Chip Financing Risk
The arrangement connects chip sales, equipment finance and an AI customer’s future revenue. Lenders provide money to the SPV, the SPV pays Broadcom for hardware, and Anthropic’s lease payments are meant to service the loans. Broadcom’s residual-value support could reduce senior lenders’ losses if the equipment has to be sold for less than the debt outstanding, but it is not the same as a guarantee that Anthropic will make every rent payment.
The scale of the lease commitments matters because Anthropic’s revenue is not fixed in the same way. Its filing says about 80% of revenue is metered usage. That means revenue depends substantially on customer use, while the described equipment rent is a contractual obligation. The filing also says rent financing can become more expensive if revenue conditions are missed and may not be available after an uncured default. These terms expose the financing structure to a mismatch if demand or revenue grows more slowly than planned.
That is a risk scenario, not evidence that Anthropic is in distress or that lenders will incur losses. Broadcom characterized its support in a separate filing as a contingent liability it believes has a low probability of occurring, citing the profitability trajectory of leading AI labs. The financing announcement itself does not disclose projected equipment resale values or lenders’ detailed loss protections beyond Broadcom’s stated support.

A Second Broadcom-Backed Compute Deal
The financing follows a June 2026 arrangement involving Apollo and Blackstone’s credit and insurance business. Broadcom said its AI XPV platform was designed to support more than 20 gigawatts of compute for frontier AI labs, including Anthropic and OpenAI, through 2028. The first $35 billion tranche, led by Apollo, was intended to fund more than one gigawatt of Anthropic compute at Fluidstack data-center sites.
In its quarterly filing for the period ending August 2, 2026, Broadcom described a backstop for that earlier lease. If a customer defaults, Broadcom said it would cover the difference between 85% of the remaining amount owed and the proceeds from selling the racks, subject to a maximum exposure of approximately $29 billion once all racks are deployed. Broadcom said the guarantee’s fair value was not material and that it had paid nothing under it as of the filing.
Anthropic’s filing also refers to a March 2026 Broadcom lease that Broadcom intended to assign to a designated financial partner, and says part of one lease had already been assigned to a third party in the second quarter. The new SPV could fit that description, but neither the announcement nor the filing confirms that connection. It should not be treated as established.
“Broadcom described such guarantees as contingent liabilities it believes have a “low probability of occurring”.”

The Terms and Risk Boundaries
The announcement does not state the interest rates, maturities, repayment schedule or detailed lien amounts. The reported $43.5 billion first-lien figure comes from Reuters, rather than the joint release. The public material also does not show how lenders would divide losses if Broadcom’s support and equipment-sale proceeds were insufficient.
It is also unclear whether the new SPV is the financial partner contemplated in Anthropic’s earlier filing, how much of the potential $42 billion in Broadcom rent notes Anthropic will use, and whether any notes have been issued. The filing describes conditions that could make rent financing more expensive or unavailable; the available information does not establish that those conditions have been triggered.
A Wall Street Journal account, reported by Benzinga, said some banks considered leaving the deal as rates rose and that Broadcom agreed to higher rates and offered additional comfort on loss guarantees during weekend talks. That account rests on a single report and is not detailed in the public announcement. The banks and Anthropic are not quoted in the supplied deal material.
Delivery and Financing Disclosures
The next practical milestone is the planned equipment delivery beginning in 2027, followed by the start of rent payments when the equipment is ready for service, as described in Anthropic’s filing. That filing says rent may begin earlier if a data center is delayed. Actual deployment, use and payment performance will help show how the financing operates, but the announcement does not provide a detailed delivery calendar.
Further filings or statements from the lenders, Broadcom and Anthropic may clarify the financing’s final terms, the link between the SPV and earlier lease assignments, and the amount of any rent notes Anthropic issues. Until then, the confirmed picture is a large lender-funded hardware purchase supported by a Broadcom value backstop and repaid through Anthropic’s lease obligations; the ultimate allocation of risk remains only partly public.
