Broadcom, Lambda and Meta show who is really financing the AI boom: the suppliers

Broadcom chief executive Hock Tan told a panel in Singapore on Monday, Oct. 12, that capital will be the biggest constraint on his company as AI development continues, ahead of the wafer and memory shortages it is working through, Reuters reported. He added that Anthropic and OpenAI have shown they can generate significant revenue from their newest models.

Tan has a front-row seat on that constraint because Broadcom is already supplying some of the capital. Anthropic’s IPO filing shows Broadcom agreed to lend the lab up to $42 billion, CNBC reported on Oct. 1, through notes that can convert into Anthropic shares. The money could cover about a third of Anthropic’s $125.2 billion commitment to lease TPU computing capacity, the custom AI chips Google and Broadcom design together, for five years. Anthropic is expected to become Broadcom’s largest compute customer in 2027.

So the chip vendor is lending a customer expected to become its largest the money to rent its chips. Anthropic’s own prospectus flags the “potential conflicts of interest” in that arrangement.

The same pattern shows up one rung down. Lambda, which rents Nvidia GPU capacity to AI companies, is raising up to $4 billion at a $14.5 billion valuation before the new money, TechCrunch reported on Oct. 6, citing the Wall Street Journal. An investor letter the Journal reviewed shows Lambda’s backlog, the contracted revenue it has not yet delivered, jumping from $15 billion in June to $50 billion in September. Much of that increase appears to come from a single $35 billion commitment Anthropic signed in late August. Lambda pays for the data centers behind that backlog mostly with debt, and it raised another $1 billion of it the week before.

A client memo from the law firm Quinn Emanuel, which Semafor’s Liz Hoffman reported was circulating on Wall Street last week, lays out how Meta paid for its Hyperion data center in Louisiana. A company called Beignet Investor, owned 80% by Blue Owl Capital and 20% by Meta, raised about $27 billion in loans to build it and leases it to Meta, and those loans do not appear as a liability on Meta’s books. Meta separately promised Beignet’s investors up to $28 billion if the building is worth less than a set threshold later, a residual value guarantee that the memo says sits only in the footnotes of Meta’s annual report, with no liability recorded.

Quinn Emanuel is a litigation firm, and Semafor’s Hoffman noted it is talking its book. If these deals go bad, the firm stands to win the court work. The memo’s facts come from public filings and offering documents.

That memo’s own history lesson cuts closer to Broadcom than to Meta. It compares the circular money in AI, such as Nvidia investing in customers who then buy Nvidia chips, to the late-1990s vendor financing at Nortel and Lucent, which lent money to telecom customers so they could buy Nortel and Lucent gear. When those customers defaulted, the loans were worthless and the sales they had produced turned out to be illusory.

Read those three deals together and the risk has moved to an unusual place. In a normal buildout, banks and bond buyers decide who gets funded, and a supplier’s worst case is an unpaid invoice. Here the supplier is the lender, the landlord’s debt is parked in a separate company with the tenant’s guarantee in a footnote, and a cloud startup’s valuation rests on one customer’s purchase order. The people with the clearest view of whether Anthropic can pay are the people who already need it to.

When the largest custom-chip supplier says capital is the bottleneck, he is describing his own balance sheet as part of the supply chain. Every extra dollar Broadcom lends brings in chip revenue and also adds to what it is owed by the customer generating that revenue.

Lambda’s numbers show how concentrated that bet already is. Anthropic’s $35 billion commitment is 70% of Lambda’s entire $50 billion backlog and about 2.4 times the company’s $14.5 billion pre-money valuation. Add it to the $125.2 billion TPU lease and two disclosed contracts alone put $160.2 billion of Anthropic’s compute bills with two suppliers, one of which is also lending it the money.
