What is written down on the site
The Piketon site in Ohio is being built by SB Energy, a SoftBank subsidiary, and OpenAI signed a lease in June that can run for 20 years. Citing The Wall Street Journal, Al Jazeera reports that Nvidia is in talks to guarantee roughly $250bn of financing for the 10-gigawatt centre; the project's total cost is reported above $500bn, of which $350bn is chips. On the power side the only schedule is 800 megawatts by 2028. A separate $33bn US–Japan arrangement covers the natural gas plant that would feed the site. Neither OpenAI nor Nvidia commented.[1]
Put these on one denominator. 800 megawatts is eight per cent of 10 gigawatts, and it is the only quantity carrying a year. The 10 gigawatts describes capacity to be leased, not capacity energised. For the 9.2 gigawatts in between, the report gives no year, no line and no generation source. A megawatt figure for two years out, set in the same sentence as a decade-long target for the same site, reads to the reader as one project scale; but one rests on a contract and the other on intent.[1]
A financing guarantee is not a payment
The $250bn in the report is described as a financing guarantee, not a purchase or an investment. A guarantee changes whose balance sheet carries the risk of the loan: the obligation arises for the guarantor only if the borrower cannot pay, and nothing leaves the guarantor's account while it can. That is a different item from the $350bn of chips in the same sentence. One is a contingent liability, the other the price of hardware to be sold, and the report does not say in what order or on what triggers either comes into force.[1]
A supplier guaranteeing its customer's financing does two things at once: it holds up demand and it concentrates counterparty risk in one place. Aleksandar Tomic of Boston College, questioning whether demand is as large as it appears and noting that the money runs out at some point, is speaking to the second part. Care is needed here, though: the reported $250bn may be a ceiling, and the guarantee may be narrow and heavily conditioned. Because neither company commented, there is no document today showing what the conditions are.[1]
How the move from paper to hardware becomes visible
On 25 July, comparing two Korean announcements, I wrote that what set them apart was not scale but whether the financing condition was written down. The same distinction holds for Piketon: what is written is the lease and the 800 megawatts for 2028; what is not written is the amount, term and triggers of the $250bn guarantee. Of two sentences about the same site, one can be checked today and one cannot.[1], [2]
Unless one of two things happens by the end of 2026, the project stays on the announced-capacity rung: either the amount and conditions of the guarantee are confirmed by one of the companies in its own statement, or a grid-connection or commissioning step beyond the 800 megawatts is documented. Those are the signals to watch, not a change in the number of gigawatts to be leased.[1]
