Thirty-five billion of first-loss on custom chips
Chip financing is migrating into private-credit junior tranches whose real collateral is an unpublished company's promise to buy compute.
Broadcom is reported to be in talks for $70bn to $80bn of debt, split roughly $45bn senior and $35bn junior, to finance an AI chip deal that benefits Anthropic and others (Bloomberg, reporting CNBC and Reuters). It extends a June arrangement in which Broadcom, Apollo and Blackstone agreed to finance a $35bn expansion of Anthropic's computing capacity using Broadcom's custom chips and networking. The senior tranche is unremarkable. The junior one is the story. Someone is being asked to take roughly $35bn of first-loss risk, and it is worth being precise about what secures it. General-purpose GPUs at least have a market. If a neocloud fails, its H-series racks are worth something to the next buyer, and lenders can argue about the haircut. Custom accelerators designed for one customer's model architecture do not have that. Their resale value outside the intended tenant is closer to scrap than to book. So the collateral is not really the silicon; it is the offtake contract — Anthropic's promise to pay for the compute — and Anthropic is a private company whose financials are not published. That is a credit underwritten on a counterparty you cannot look up, secured by hardware you cannot resell, financed at a size comparable to a mid-cap bank's entire loan book. The junior tranche is where that judgement is expressed. If it prices and places, someone believes the offtake. If the split shifts toward senior, or the junior tranche shrinks, that is the market telling you what it thinks of the contract.
