- Broadcom says Anthropic will access approximately 3.5 gigawatts of additional Google TPU-based capacity beginning in 2027, but warns that consumption depends on Anthropic’s continued commercial success. [1] - A separate initial transaction covers more than one gigawatt beginning in mid-2026. Apollo leads a $35 billion capital package, while Broadcom backstops the customer’s five-year lease obligations up to $29 billion. [4][5] - Alphabet separately disclosed $43.8 billion of maximum exposure under data-center credit backstops, compared with an $815 million fair-value liability. It also reported $7.6 billion of energy guarantees and an agreement for an estimated $24.1 billion of additional backstops. [7] - The debt belongs to outside vehicles, but public filings do not establish whether Anthropic must recognize corresponding lease liabilities or consolidate any vehicle. Calling the entire arrangement off balance sheet for Anthropic is therefore premature.
Anthropic’s Google TPU expansion rests on two distinct financing layers that are easy to conflate. One funds the AI racks: Apollo and other investors took on $35 billion of purchase and lease agreements, while Broadcom agreed to backstop as much as $29 billion of the customer’s five-year lease obligations. The other supports data centers and power infrastructure, where Alphabet has provided separate guarantees that help developers obtain financing.[4][5][7]
Those layers are commercially connected, and independent reporting identifies Anthropic as an important end user of the resulting capacity. They are not one legal vehicle, however. Broadcom’s backstop covers AI-rack lease obligations. Google’s disclosed backstops cover payment obligations tied to data centers and energy infrastructure, with rights to assume or sublease facilities after specified defaults.[5][7][8]
The practical effect is to put asset ownership and much of the borrowing outside Google and Anthropic while using stronger corporate balance sheets to make the projects financeable. The risk has been divided and repriced, not eliminated. Both chip and facility payments ultimately rely on Anthropic using and paying for enormous amounts of compute.
Two capacity announcements, not one transaction #
In April, Broadcom disclosed that Anthropic would access approximately 3.5 gigawatts of next-generation TPU-based AI capacity through Broadcom beginning in 2027. The capacity is part of an expanded collaboration among Anthropic, Google and Broadcom. Broadcom also cautioned that Anthropic’s consumption would depend on its continued commercial success.[1]
Anthropic described the agreement as its most significant compute commitment to date, but neither Anthropic nor Google disclosed a dollar value. Reporting by The Information later put Anthropic’s commitment to Google Cloud and Google chips at roughly $200 billion over five years. That figure should remain attributed: it has not been confirmed in the companies’ public announcements or filings.[2][3]
The $35 billion financing announced in June is related but has a different timetable and stated capacity. Apollo said the initial transaction would facilitate more than one gigawatt of Anthropic infrastructure for training and inference beginning in mid-2026. Broadcom’s April filing describes an additional 3.5 gigawatts beginning in 2027. Public disclosures do not establish that the $35 billion package finances all of the later 3.5-gigawatt commitment.[1][4]
Who owns the chips and who owes the money #
Apollo describes the $35 billion package as the initial transaction in Broadcom’s AI XPV Platform, backed by Apollo-managed funds, Blackstone and global banks. The platform is intended to enable more than 20 gigawatts of compute capacity for frontier AI developers through 2028.[4]
Broadcom’s subsequent quarterly filing provides the clearest description of the legal chain. On June 8, Broadcom arranged for Apollo to take on agreements to purchase AI racks based on Broadcom-designed custom accelerators, along with related agreements that lease the resulting compute capacity to a customer. Apollo’s announcement identifies Anthropic as the beneficiary of the initial financing, although Broadcom’s filing refers only to a customer.[4][5]
The investor vehicle therefore becomes the purchaser and lessor of the AI racks rather than Google or Anthropic buying them directly. The Financial Times identified the special-purpose vehicle as Compute SPV, formed through Apollo’s Atlas SP Partners, and reported that it would issue debt supported by Anthropic’s five-year lease payments.[6]
Broadcom is not simply guaranteeing the vehicle’s debt. Its filing says it is backstopping the customer’s lease obligations to Apollo. The exposure rises as racks are deployed, falls as the customer makes lease payments and is capped at $29 billion. If the customer defaults, Broadcom can assume the lease or arrange a sale of the racks, reducing the amount it owes.[5]
That distinction matters. A debt guarantee would directly promise payment of specified securities. Broadcom instead supports the cash flow that services the financing and retains remedies involving the underlying equipment. Economically, the backstop protects investors from a large portion of the customer risk, but the precise loss waterfall and treatment of different investor classes have not been publicly filed.
Google’s guarantees sit at the data-center layer #
Alphabet’s role is more visible around the buildings and power systems that house AI hardware. Its June-quarter filing disclosed $43.8 billion of notional exposure under credit derivatives that backstop payment obligations related to data centers, up from $16.9 billion at the end of 2025. Alphabet recorded an $815 million liability representing the instruments’ fair value.[7]
The figures measure different things. The $43.8 billion is the maximum exposure under specified default scenarios. The $815 million is Alphabet’s estimate of the obligations’ value based on factors including default risk and potential recoveries. The larger amount is disclosed in the filing, but it does not appear as conventional debt on Alphabet’s balance sheet.[7]
Alphabet also disclosed $7.6 billion of maximum payments under financial guarantees supporting the procurement of long-lead equipment for future energy agreements. In addition, it had agreed to provide an estimated $24.1 billion of further data-center and energy backstops, subject to final terms with project developers.[7]
If a supported party defaults, Alphabet can assume the underlying data-center lease for its own use, sublease it to another party or, under specified conditions, make a termination payment. Any obligation may also be partly offset by equity or cash received from counterparties.[7] The Information reported that many of the projects involve Fluidstack leasing and operating facilities, installing Google TPUs and renting capacity to Anthropic. It said Alphabet had backed about 2.4 gigawatts across roughly 10 projects, none of which was complete when the report was published. These project counts and the identification of Anthropic as the ultimate user come from people familiar with the arrangements, not Alphabet’s filing.[8]
What remains on each party’s balance sheet #
The vehicle’s borrowing does not become conventional debt of Google or Anthropic merely because they use or support the assets. That does not establish that Anthropic carries no corresponding liability.
Lease accounting depends on contractual control, the right to direct use of the equipment and other terms that have not been published. Anthropic is privately held and has not released financial statements showing whether it recognizes a right-of-use asset and lease liability or whether it must consolidate any special-purpose vehicle. The article’s earlier claim that the hardware was definitively off Anthropic’s balance sheet went beyond the available evidence.
Google’s position is clearer. Alphabet accounts for its data-center backstops as credit derivatives and records them at fair value, while separately disclosing maximum notional exposure. The guarantees are therefore not hidden, but a balance sheet viewed without its footnotes would understate the scale of the contingent obligations.[7]
Broadcom also records a defined contingent exposure. Its $29 billion maximum backstop is linked to rack deployment and Anthropic’s payments, with the underlying equipment providing a potential recovery route. That recovery value will depend on the condition, compatibility and marketability of the racks at the time of any default.[5]
The same financing logic is spreading across AI #
The Anthropic arrangements combine techniques already appearing elsewhere in AI infrastructure: an outside owner acquires the assets, a long-term customer contract supplies the cash flow, and guarantees or collateral improve the lender’s recovery prospects.
Meta and Blue Owl created a joint venture to own and develop the Hyperion data-center campus in Louisiana, which Meta will lease. Meta provided a declining residual-value guarantee with an initial threshold of about $28 billion. Its annual filing placed maximum exposure associated with the venture at $45.95 billion at the end of 2025, including its investment, lease commitments, expected funding and guarantee exposure.[9][10]
Apollo used an equipment-lease variation for xAI. A Valor Equity Partners fund acquired $5.4 billion of infrastructure, including Nvidia GB200 systems, and leased it to an xAI subsidiary under a triple-net structure. Apollo supplied a $3.5 billion capital package, while Nvidia invested as an anchor limited partner in the Valor fund.[11]
CoreWeave’s delayed-draw financing offers another comparison. Its filings say borrowing availability under one facility was limited to a percentage of the depreciated purchase price of GPU servers and related infrastructure, with that percentage determined by the applicable customer’s credit rating. The loans were collateralized by infrastructure assets and contractual cash flows.[12]
Google’s Anthropic buildout extends that logic across custom chips, data centers and power systems. It also exposes the model’s central dependency. Broadcom’s filing states that Anthropic’s expanded consumption depends on its continued commercial success; the initial rack backstop rises as equipment is deployed and declines only as the customer pays.[1][5]
Before investors can quantify the downside, the parties would need to disclose Anthropic’s lease-accounting treatment, termination provisions, the investor vehicle’s capital structure and the overlap between Google’s project backstops and the capacity covered by the Broadcom-Apollo arrangement. Until then, the defensible conclusion is not that Google moved $200 billion of risk off its balance sheet. It is that Google, Broadcom and Wall Street engineered several layers of financing around a customer whose growth must support all of them.
