Anthropic to lease Broadcom AI chips through $63 billion financing from Bank of America, Blackstone, Citi and Morgan Stanley
Anthropic will lease Broadcom AI accelerators and networking equipment through a newly formed special purpose vehicle backed by a $63 billion financing package, according to an announcement issued on October 26, 2026 by Bank of America, Blackstone, Citi and Morgan Stanley and published on Broadcom's investor relations site. The four institutions, which the release calls the "Lead Financial Partners", describe the transaction as a way to deploy AI compute capacity built on Broadcom technology for Anthropic, and they place it inside the strategic compute capacity agreement that Broadcom had already disclosed earlier in the year. Deliveries of the hardware are expected to begin in calendar 2027.
The structure is the most detailed public description so far of how Anthropic's largest compute commitment will be paid for. Instead of Anthropic buying the chips outright, the vehicle will purchase Broadcom XPU AI accelerators and networking solutions and lease them to Anthropic. Bank of America, Citi and Morgan Stanley are arranging the first lien financing, Blackstone is the sole provider of the committed portion of the second lien financing, and Broadcom will provide residual value support to the vehicle in an amount equal to the first lien. In practice, that last element means Broadcom stands behind the value of the hardware for the portion of the debt that sits at the top of the repayment order.
The announcement arrived on the same day Anthropic filed its registration statement for a Nasdaq listing, a filing Data Studios covered in Anthropic files S-1 for Nasdaq IPO under ticker ANT. It also turns into an official, quantified transaction what earlier in October was only a reported plan, described in Anthropic reportedly seeks $60 billion in AI chip financing. The final figure is $63 billion, and the participants, roles and delivery window are now on the record.

HOW THE $63 BILLION STRUCTURE WORKS.
The special purpose vehicle sits between the lenders, the chip supplier and the end user. It raises debt in two layers, uses the money to buy Broadcom hardware, and collects lease payments from Anthropic, which is named in the release as the lessee and the user of the compute capacity. The release does not say who owns the equity of the vehicle, what share of the $63 billion each lien represents, or how long the leases run.
........
Role | Party | What the release says |
Hardware buyer and lessor | New special purpose vehicle | Buys Broadcom XPUs and networking, leases them to Anthropic |
Lessee and end user | Anthropic | Uses the compute capacity |
First lien financing | Bank of America, Citi, Morgan Stanley | Arrangers of the first lien |
Second lien financing | Blackstone | Sole provider of the committed portion |
Residual value support | Broadcom | Equal to the first lien amount |
Hardware supplier | Broadcom | XPU AI accelerators and networking solutions, deliveries from calendar 2027 |
........
The residual value support is the clause that most changes the risk profile for the senior lenders. AI accelerators lose value quickly as new generations arrive, and a lender financing chips over several years has to estimate what the equipment will be worth if the lessee stops paying or the leases end. By committing to support the hardware's residual value up to the size of the first lien, Broadcom absorbs part of that uncertainty itself. The release does not describe the mechanics, such as whether the support takes the form of a buyback price, a guarantee payment or another instrument, and it gives no figure for the first lien, so the size of Broadcom's exposure cannot be calculated from public information.
Blackstone's position is different. As the sole provider of the committed portion of the second lien, it sits below the banks in the repayment order and therefore takes more risk in exchange for a higher expected return. The wording "committed portion" implies that part of the second lien may be filled later or by other investors, but the release does not say how large that remaining portion is.
Advisers are named in full: Kirkland & Ellis represented Blackstone, Latham & Watkins represented Bank of America, Citi and Morgan Stanley, Sullivan & Cromwell represented Broadcom, and Evercore acted as Broadcom's financial adviser. No adviser to Anthropic is listed, and the release contains no statement from Anthropic.

WHAT THE PARTICIPANTS SAID.
The release carries quotes from all five companies on the supplier and lender side. Hock Tan, President and CEO of Broadcom, presented the deal as evidence that capital is available to finance AI growth and said Broadcom is "uniquely positioned to enable it". Jon Gray, President and COO of Blackstone, tied the transaction to growing demand for AI compute and the opportunity to finance capacity at scale.
The banks used similar language about scale. Dan Simkowitz, Co-President of Morgan Stanley, called the deal an important milestone for the next phase of AI compute buildout. Vis Raghavan, Head of Banking and Executive Vice Chair at Citi, said financing AI requires capital solutions at unprecedented scale, and Jim DeMare, Co-President of Bank of America, said the transaction combines Broadcom's technology with significant bank capital to accelerate the buildout of compute.
None of the quotes adds financial terms, and the release closes with the standard forward-looking statement language: the deployment of compute capacity through the vehicle and its timing depend on current expectations and are subject to risks including market conditions, customer demand, supply chain, competition and indebtedness. Broadcom states that it does not intend to update these statements except as required by law.

HOW THIS FITS ANTHROPIC'S BROADCOM AND TPU COMMITMENTS.
The October transaction is the financing layer of an agreement that has been building since April. On April 6, 2026, Anthropic announced an expanded deal with Google and Broadcom for multiple gigawatts of next-generation TPU capacity starting in 2027, which it described as its largest compute commitment to date and said would be sited mostly in the United States. Broadcom's Form 8-K filed the same day was more specific: beginning in 2027, Anthropic will access approximately 3.5 gigawatts of next-generation TPU-based AI compute through Broadcom, as part of the multiple gigawatts Anthropic has committed to.
That 8-K also contained two sentences that anticipated this week's announcement. It stated that Anthropic's consumption of the expanded capacity "is dependent on Anthropic's continued commercial success", and that the parties were "in discussions with certain operational and financial partners" for the deployment. The $63 billion vehicle is the financial side of those discussions, although the October release does not repeat the 3.5 gigawatt figure or state how much of that capacity the $63 billion covers.
A second, separate Broadcom structure already existed. On June 9, 2026, Broadcom, Apollo and Blackstone announced the AI XPV Platform, a framework for deploying compute built on Broadcom XPUs and networking, launched with an initial $35 billion tranche led by Apollo with Blackstone as a partner and anchor investor. Broadcom said that platform was designed to enable more than 20 gigawatts of capacity through 2028, named Anthropic and OpenAI as target customers, and said its initial tranche supported Anthropic's previously announced expansion of more than 1 gigawatt of infrastructure at Fluidstack-based sites from mid-2026.
........
Date | Announcement | Key disclosed figures |
April 6, 2026 | Anthropic, Google and Broadcom expand compute deal | About 3.5 GW of TPU-based compute via Broadcom from 2027 |
June 9, 2026 | Broadcom, Apollo and Blackstone launch AI XPV Platform | $35B initial tranche, more than 20 GW targeted through 2028 |
October 26, 2026 | Four lead financial partners announce SPV for Anthropic | $63B financing, deliveries from calendar 2027 |
........
One wording difference is worth noting. Anthropic's April announcement and Broadcom's 8-K describe the 2027 capacity as TPU-based, while the October release speaks of "Broadcom XPU AI accelerators". Broadcom uses XPU as its general term for the custom accelerators it designs with customers, and the 8-K also describes Broadcom developing and supplying custom TPUs for Google. The October release does not state whether the leased accelerators are the same TPU generation referenced in April, so the two descriptions should not be treated as confirmed to be identical hardware.

WHY ANTHROPIC IS LEASING RATHER THAN BUYING.
Anthropic's registration statement shows why the financing method matters. In the prospectus summary, the company says it runs a multi-chip architecture across AWS Trainium, Google TPUs, NVIDIA GPUs and AMD GPUs, and manages compute as a single pool from several strategic partners. The same filing reports compute and infrastructure expenses of $8,945 million in the first six months of 2026, compared with $2,334 million in the first six months of 2025 and $7,326 million for the whole of 2025. Spending in one half-year has therefore already exceeded the previous full year.
The S-1 also states that Anthropic has entered into purchase commitments and lease agreements, including leases not yet commenced, with an aggregate committed spend substantially all related to compute and infrastructure, expected to run partly before the end of 2030 and substantially all of the remainder between 2031 and 2045. In the version of the document reviewed for this article, the dollar totals for those commitments were left blank, which is common in an initial registration statement before pricing details are filled in.
Leasing through a vehicle financed by third parties spreads the cost of hardware over time instead of concentrating it in an upfront purchase, and it moves the financing of the chips onto lenders that specialize in pricing that risk. The interpretation that this structure is intended to preserve Anthropic's own cash and balance sheet capacity ahead of its listing is Data Studios' reading of the arrangement, not a statement made by Anthropic or the lenders; none of the parties has explained the choice publicly.
··········
WHAT IT MEANS FOR CLAUDE CAPACITY AND CUSTOMERS.
For people who use Claude in the apps or through the API, nothing changes immediately. The hardware financed by this vehicle is not expected to start arriving until calendar 2027, and the release gives no schedule for when it will be installed, brought online or used for specific models or services. There is no announcement of new plans, limits or prices linked to the transaction.
The longer-term relevance is capacity. Anthropic has repeatedly tied compute agreements to demand from customers, and in its April announcement it said the new TPU capacity would power its frontier Claude models and help meet that demand. A financed path for a large block of 2027 hardware makes that capacity more likely to materialize on schedule, but how it will be split between training and serving Claude, and whether it will translate into higher usage limits or lower prices, has not been disclosed. Enterprises planning large Claude deployments for 2027 and beyond should treat the deal as a signal about Anthropic's supply planning, not as a commitment about service levels.
For Broadcom, the transaction strengthens the link between its custom accelerator business and Anthropic's growth, but it also adds a contingent exposure through the residual value support. That exposure, together with the 8-K's statement that Anthropic's consumption depends on its commercial success, is the part of the deal that investors in both companies will want quantified in future filings.
··········
WHAT IS ESTABLISHED AND WHAT REMAINS UNDISCLOSED.
The established facts come from the October 26 release and Broadcom's earlier filings. A $63 billion financing has been arranged for a special purpose vehicle that will buy Broadcom XPU accelerators and networking and lease them to Anthropic, with Bank of America, Citi and Morgan Stanley arranging the first lien, Blackstone providing the committed portion of the second lien, Broadcom giving residual value support equal to the first lien, and deliveries expected from calendar 2027. The deal is part of the strategic compute capacity agreement first disclosed in April, which Broadcom's 8-K quantified at approximately 3.5 gigawatts of TPU-based compute for Anthropic from 2027.
Several key terms are not public. The release gives no split between first and second lien, no lease duration or pricing, no capacity in gigawatts for this specific vehicle, no description of the residual value mechanism, and no comment from Anthropic. Anthropic's S-1 confirms large long-dated compute commitments but, in the version reviewed, leaves the totals blank. Those missing figures, which are likely to appear in later amendments to the registration statement or in Broadcom's periodic reports, will determine how much of the $63 billion represents firm obligations for Anthropic and how much risk Broadcom retains.
