Wall Street Gave Anthropic $63B for Chips It Won't Own

 

Wall Street has just agreed to buy $63 billion worth of somebody else's computer chips, lease them to a company that is losing money on paper at a spectacular rate, and let the chipmaker itself promise the lenders they will be fine. If that sentence sounds like it cannot possibly describe a real, signed financing, welcome to the AI buildout in October 2026 — where the numbers have got so large that the only thing stranger than the deal is how routine it now feels.

On Monday, October 26, Bank of America, Blackstone, Citigroup and Morgan Stanley announced $63 billion in financing to buy Broadcom's AI accelerators and networking equipment for Anthropic, the company behind Claude. The money does not go to Anthropic. It goes to a newly formed special-purpose vehicle — a company created for this deal and nothing else — which will buy the hardware and lease it to Anthropic, with deliveries expected to begin in 2027 under a previously announced compute-capacity agreement with Broadcom. Anthropic gets the chips without buying them. Broadcom gets paid. The banks get a lease stream. Everybody, on paper, wins.

That is the press-release version. The interesting version starts with the parts the announcement does not say.

The $63 billion, sliced four ways

Bank of America, Citigroup and Morgan Stanley are arranging the first-lien financing — the senior debt that gets paid back first if anything goes wrong. Blackstone is providing the committed portion of the second-lien financing, the junior debt that only gets paid after the senior lenders are whole. The announcement itself did not disclose the split. Two sources familiar with the matter told Reuters the first-lien piece is about $43.5 billion, or roughly 69 percent of the total. Treat that as reported, not announced: the release keeps the breakdown to itself, and Broadcom did not respond to Reuters' request for comment.

The tenor matters as much as the size. Morningstar Equity Research, which covered the deal the next day, describes it as $63 billion in total financing over five years. Five years is roughly the useful life of a generation of AI accelerators — which is to say, the lenders will still be collecting when today's cutting-edge XPU is two generations out of date. That is not a criticism; it is the entire bet. The bet is that Anthropic will still want this hardware, or hardware like it, for a very long time, and that if it does not, somebody else will.

Citi's Vis Raghavan, the bank's head of banking and executive vice chair, put the scale of the moment plainly in the announcement: "Financing AI demands capital solutions at unprecedented scale." He is not wrong. He is also, notably, not the one taking the strangest risk in this deal. That honour belongs to Broadcom.

Broadcom is on three sides of its own sale

Read the announcement twice — and we did — and one clause keeps snagging the eye. Broadcom is providing what the companies call "residual value support" to the senior lenders. In plain English, Broadcom is effectively guaranteeing the first-lien debt against a fall in the value of the equipment it just sold. If the chips are worth less than the senior debt when the music stops, Broadcom absorbs the shortfall, up to the amount of that debt. The seller is insuring the buyer's lenders against its own product losing value.

That is not unprecedented — chipmakers have provided guarantees like this before — but the scale is new, and so is the layering. Broadcom is the seller of the hardware, the guarantor of the senior debt, and, through a separate arrangement disclosed in Anthropic's IPO filing the very same day, a potential lender to Anthropic itself: the filing says Anthropic may issue up to $42 billion in convertible notes to Broadcom to finance its rent obligations. One company, three seats at the same table. Our own October coverage of that earlier $42 billion facility — Broadcom's $42 billion loan to lease Anthropic its own chips — now reads less like a curiosity and more like a template.

None of this is secret. All of it is in documents the companies published themselves. What is striking is how little anybody involved seems to think it needs explaining. Morningstar's analysts, for their part, say they have "low concern" about the backstop: in their view, Broadcom is only on the hook in a worst case where Anthropic defaults and AI demand collapses so far that the chips cannot be repurposed. That is a coherent argument. It is also an argument that depends entirely on the words "worst case" doing a great deal of heavy lifting.

The $161 billion question nobody will answer

Here is where the story gets properly awkward. On the same day the $63 billion deal was announced, Anthropic filed its IPO prospectus. That filing describes Broadcom equipment leases totalling about $161.2 billion in rent over five years, excluding interest — including a March 2026 lease alone worth about $125.2 billion in rent, which Broadcom, according to the filing, intends to assign to a designated financial partner. Anthropic cannot cancel those leases except in a default.

So the obvious question writes itself: is the new $63 billion vehicle the "designated financial partner" for that March lease? Does the $63 billion cover all of the $161.2 billion, or only part of it? The announcement does not say. The filing does not say. Analysts who have picked through both documents this week are explicit that neither one confirms the link. Until somebody does, there are two numbers floating around — $63 billion of fresh financing, $161.2 billion of lease rent — and no confirmed bridge between them. Any article that adds them together, or treats one as a subset of the other, is guessing. We are not going to.

What the filing does confirm is the scale of Anthropic's appetite, and its cost. Summaries of the prospectus put first-half 2026 revenue at about $16.3 billion, up from $1.16 billion a year earlier, alongside a first-half net loss of about $80.7 billion — most of it, about $72.4 billion, a non-cash revaluation of convertible notes driven by Anthropic's own rising valuation, not cash walking out the door. That distinction matters, and it is the reason the banks can lend $63 billion to a company with an $80 billion headline loss in the same breath: the cash business and the accounting loss are telling different stories. Whether the cash story stays that good is the whole gamble.

Why the banks said yes — and why the market cheered

The timing was not an accident. Anthropic's IPO filing landed the same day, and the market spent the next 48 hours treating the pair of announcements as proof that demand for AI infrastructure is not a story but a queue. Broadcom shares added about 1.3 percent after hours on Monday, according to market reports. On Tuesday, the Philadelphia Semiconductor Index rose 2.8 percent, its largest single-day gain in a month, as chip stocks rallied for a third straight session. Chuck Carlson, chief executive of Horizon Investment Services, told Reuters the Anthropic news "seems to be giving a little bit of a relief rally to the AI stocks, particularly the semis" — a polite way of saying that stocks which had been, in his words, clobbered in recent weeks were due a bounce, and this was as good an excuse as any.

Morningstar, meanwhile, is considerably more bullish than "due a bounce." Its analysts expect this deal alone to drive nearly $60 billion in Broadcom revenue in 2027, expect Anthropic to become Broadcom's largest customer that year, and maintain a $650 fair-value estimate on the stock with a five-star rating. They also note, with unusual bluntness for a research note, that Broadcom shares have been "down lightly in 2026 despite ballooning growth" — their explanation being long-term market worries about whether AI spending lasts. Read that sentence alongside the $63 billion and you get the deal's real pitch: the spending is not slowing, the only question is who finances it, and the answer, increasingly, is everybody at once.

There is precedent, and it is recent. A June vehicle led by Apollo, worth $35 billion, already buys Broadcom-designed racks and leases them to Anthropic. The $63 billion deal is not the invention of a new machine; it is the machine getting bigger, with bigger banks, on the same day the customer filed to go public. If you have been following this blog's coverage of AI's debt machine, none of the plumbing will surprise you. Only the diameter of the pipes has changed.

What could still go wrong

Start with the obvious. A residual-value guarantee is only as good as the resale market for used AI accelerators in 2029 and 2030, and nobody has ever run a resale market at this scale, for this kind of hardware, through a downturn. If Anthropic thrives, the guarantee never gets called and everyone looks clever. If AI demand merely cools — not collapses, just cools — the senior lenders will discover what their collateral is actually worth, and Broadcom will discover what its promise actually costs. Morningstar's "worst case" is not a tail event invented by sceptics; it is the scenario the guarantee exists for.

Then there is concentration. One supplier, one customer, four lenders, $63 billion. Anthropic's filing also names at least $114.5 billion in commitments with Google, $110 billion with Amazon and $44.9 billion with Microsoft, according to filing summaries — a reminder that this deal is one room in a much larger house of obligations. If any one of those rooms catches fire, the others do not stay dry. Broadcom chief executive Hock Tan said in Singapore earlier this month that capital, not chips, is now the biggest constraint on AI growth — a line we covered at the time — and this deal is his thesis wearing a banker's suit: the chips exist, the money is the bottleneck, and the bottleneck is being solved by lending against the chips themselves.

Finally, there is the disclosure gap that should bother readers more than it seems to bother the market. A $63 billion financing whose tranche split comes from unnamed sources, whose relationship to a $161.2 billion lease stack is unconfirmed, and whose guarantor is also the seller, is a lot of opacity for a deal announced on IPO day. None of that makes it improper. All of it makes it worth watching with both eyes open — and worth revisiting the moment any of the three unknowns gets an official answer.

Our take: this is either genius or a loop, and the difference is resale value

Strip away the acronyms and the deal is beautifully simple: a chipmaker sells chips to a vehicle funded by banks, the vehicle rents them to an AI lab, and the chipmaker promises the banks the chips will hold their value. If the lab keeps growing, the loop spins faster and everyone gets rich. If it does not, the loop runs in reverse, and the same three parties discover they were each other's counterparty all along.

Whether this is genius or a house of cards will be decided by one number that does not exist yet: what a used Broadcom XPU is worth in 2029. Until then, the honest verdict is narrower than either the bulls or the bears want. The $63 billion is real, the banks are real, the guarantee is real, and the gap between the financing and the lease stack is real too. The market has chosen to celebrate the first three and ignore the fourth. We checked the announcement, the filing summaries and our own archive before writing this — and the fourth is the one we will be watching.
