Anthropic's US$63bn compute SPV: the chipmaker backs the residual value.
A new special purpose vehicle will buy Broadcom AI racks and lease them to Anthropic, funded by a first lien arranged by three banks and a second lien from Blackstone. What makes it new is Broadcom's promise to cover a fall in the value of the racks, up to about US$43bn. It is the largest single compute financing in the InfraCompute register.

01The chipmaker stands behind the collateral
Broadcom does not guarantee the rent. It covers a shortfall on the hardware: if Anthropic defaults and the racks are sold, Broadcom pays the difference between 72.5% of what is owed on the lease and the sale proceeds [1]. That puts the risk of the chips' resale value, the hardest number in any GPU financing, on the party that designed them.
02The backstop moves with the lease
The support grows as racks are delivered and deployed and shrinks as Anthropic pays rent, up to about US$43bn [1]. The test is 72.5% of the lease balance, not of original cost, so it follows the amortisation. Lenders will want to see how that balance is calculated at each date and what counts as the sale value.
03Broadcom has ways to limit the call
On a lease default Broadcom can take over the lease, resell the racks to the seller at a fixed price in some cases, or arrange a sale [1]. Broadcom describes the backstop as a contingent liability with a low probability of being called. For lenders, the order in which those options run, and who controls the sale, matter as much as the cap.
04The lease is the credit
Anthropic's leases run five years, are accounted for as finance leases and cannot be cancelled except on default. Rent is quarterly and usually starts when equipment is ready for service, though it can start earlier if a data centre is late [3]. Anthropic, PBC guarantees its lease subsidiaries, the equipment secures the leases and the events of default include cross-defaults [3].
05A funding line sits behind the rent
Anthropic may fund quarterly rent by issuing up to US$42bn of convertible notes to Broadcom or a designated financial partner. Interest is 9% paid in kind, 13% if revenue conditions are not met, and the notes are secured on a junior basis by the lease collateral [3]. That is liquidity support for the lessee, ranked behind the lease.
06Delivery risk sits before the rent starts
Deliveries are expected from 2027 [2]. Anthropic has placed cash in a restricted account for Broadcom's benefit and may have to add more [3]. The conditions for each delivery, what happens if racks are late and when rent starts are where the construction-phase risk sits.
October produced three different answers to the same question: who carries the value of the chips. Lambda borrowed against GPUs it owns, backed by customer contracts. SpaceX chose a finance lease from an Apollo-managed lessor that pays down with the chips' working life. The Anthropic financing adds a third party, the chipmaker, to cover the residual value.
Broadcom's release names the financial partners but not the size of each lien. The SPV's financing documents and the lease schedules for this financing have not been made public. This teardown summarises public sources for commentary and is not investment or legal advice.
