On Thursday the 10-year Treasury yield touched 5.34%, its highest since 2002, after its biggest quarterly rise this century. Reuters names two causes: energy costs feeding inflation, and an AI and data center build-out that is raising expectations for growth and for where rates will settle. The boom is pushing up the price of the money it runs on.

Lenders have noticed. Société Générale, MUFG and Sumitomo Mitsui are among the banks pulling back from data center loans and choosing safer deals as yields climb. Lower-rated borrowers now pay to stay in the market. CleanSpark, which is building a data center for Meta, had to give investors big concessions to close its financing this month.

The same morning, Reuters pulled a line out of Anthropic's IPO prospectus: Broadcom will lend Anthropic up to $42 billion, enough for about a third of a $125.2 billion, five-year lease on TPU capacity, the chips Broadcom has co-designed with Google for several generations. The notes can convert into Anthropic shares. Next year Anthropic is expected to become Broadcom's largest compute customer. Broadcom projects about $115 billion of AI semiconductor revenue in fiscal 2027 and $230 billion in 2028. Nvidia runs the same play. On Wednesday GMI Cloud, a five-year-old GPU cloud, disclosed $668 million in equity and debt from Nvidia and others.

Nvidia is putting in place a massive amount of its balance sheet, and Broadcom is having to follow suit.

Banks and bond buyers are pricing AI risk in public, deal by deal. When a chipmaker lends instead, that risk doesn't leave the system. It moves to the one balance sheet that books the same dollars as revenue.

The difference is in the incentives, not the paperwork. A bank lending against a data center wants to be repaid. A chipmaker lending to its largest customer wants to be repaid and wants the order. The order shows up first, in this year's guidance, while repayment rides on a five-year lease. Anthropic's filing names the tension itself: Broadcom's double role as supplier and financier creates "potential conflicts of interest" that could affect its access to compute. The facility also comes with the usual trapdoor. Certain payment or performance defaults could make a substantial portion of the lease obligations immediately due and limit Anthropic's ability to use the $42 billion to cover them. That is ordinary credit language. It is also the tell. Vendor money feels like conviction in good times and behaves like credit in bad ones.

The strongest objection is that none of this is new, and most of it works. Boeing helps finance its jets. Carmakers run captive lenders. A supplier often understands the asset better than a bank does. Anthropic is not a 1999 upstart carrier either; it is heading into an IPO that could value it at $2 trillion. All true. But captive finance works because the lender can take back something the next buyer wants, and airlines trade used 737s for decades. Broadcom is financing accelerator capacity that will be a generation or two old before the lease runs out. The closer precedent is telecom. In the late 1990s Lucent and Nortel lent billions to the new carriers buying their gear, and when the carriers failed, the loans and the revenue went down together. Vendor financing wasn't fraud then. It made revenue look like demand until the cycle asked for the difference.

A bank's no is a price. A supplier's yes is a sales plan. This week the AI build-out got both, and only the first came from someone who doesn't need the order.
