What the $105bn guarantee actually covers
The chip vendor is now carrying the property risk of its customer's landlord. That is exactly the kind of exposure that sits outside a bank and only gets a price when someone demands payment on it.
The structure behind Nvidia's OpenAI backstop has been described in enough detail to see the plumbing. The site is PORTS-Pike in Ohio. SB Energy builds it, owns it and operates it. OpenAI takes the tenancy, eight IT-gigawatts of it. Nvidia gets exclusive rights to supply computing power at the campus and, in exchange, promises that the initial 4.25 IT-gigawatts of infrastructure will hold a certain value, with its total obligation capped at $105bn. The promise covers land, power and buildings. It does not cover the chips (TrendForce, via 新頭殼). That carve-out is the interesting part. A residual value guarantee is a promise that an asset will be worth a specific amount at a stated future date, and whoever writes it absorbs the gap if it is not. Nvidia has written one on concrete, transformers and dirt, the parts of a data center with a long life and, in principle, a buyer other than OpenAI. It has not written one on the depreciating silicon it sells, which is the part of the stack whose second-hand value nobody can currently observe. Google has done a version of the same thing for Anthropic, guaranteeing data center rent to a total of $44bn and taking roughly 20% equity in the associated power and building projects. Broadcom, which co-designs Google's custom AI chips, has separately pledged to buy back chips that do not sell. Our fact-check of the circulating $125bn figure found the number is $105bn: talks reportedly began nearer $250bn and were revised down to under $120bn before the announced deal. What must stay true for the structure to work is that the Ohio campus has a tenant at the end of the lease. Not necessarily this one.
