Where we stand

Our current reading: if an AI company's revenue can't keep up with its compute bills, the first to take the loss are the buyer, Anthropic, and its shareholders, not the suppliers selling the compute. The basis is the IPO filing Anthropic made public on October 26. Of the five compute contracts whose terms it states, four, the three cloud providers' and Broadcom's, must be paid however much compute Anthropic actually uses. Anthropic covers a shortfall itself: the three cloud bills fall on its cash and bank line, and while the conditions hold it can also pay Broadcom's rent with money borrowed from Broadcom; the filing does not say whether that borrowing or cash is used first. Anthropic held about $131.7 billion in cash and short-term investments at the end of June. The first filing does not show who pays after that (October 27 deep dive). This revises our October 21 reading, which held that only two companies might book extra losses: Broadcom, which guarantees the rack leases, and Amazon, which owns Anthropic shares (October 21 deep dive).

The suppliers' share of the risk is still on their own books. NVIDIA's quarterly report, filed August 26, totals its guarantees in one table: about $108.5 billion at most, $105 billion of it from the SB Energy guarantees signed in August (NVIDIA 10-Q). Broadcom guarantees one customer's leases on AI racks and could have to pay up to about $29 billion; it has paid nothing so far. Its filing doesn't name the customer. Matching the documents, we infer the customer is Anthropic; that is our inference, not something the documents state (Broadcom 10-Q; October 27 deep dive). The IPO filing adds that Broadcom has agreed to lend Anthropic up to $42 billion, usable only for rack rent, and that Google, a large shareholder, has promised up to $20 billion (October 27 deep dive). The big cloud providers themselves still have room to borrow, but Amazon already has more debt than cash. Part of the debt has also turned into data-center leases running ten years or more, and part sits with the companies that build data centers for them. We revised our July call to this view on October 23 (October 23 deep dive).

Next reading to watch: whether later versions of the IPO filing say who pays once cash no longer covers the shortfall.
