Nvidia cuts its planned backstop for OpenAI's Ohio data center to under $120 billion

The $250 billion guarantee Nvidia was discussing for OpenAI’s Ohio campus in July has shrunk by more than half.

What the Journal reports

The Wall Street Journal reported on August 14 that Nvidia has cut its planned financial backstop for OpenAI’s Ohio data center to under $120 billion, down from the roughly $250 billion discussed in July. The new structure covers only the project’s first phase. Per the WSJ, a deal could be signed within days.

The campus itself has not changed. It is a 10-gigawatt site in Piketon, Ohio, developed by SB Energy, SoftBank’s energy arm, with Nvidia guaranteeing the financing that lets OpenAI lease it. What changed is the appetite for risk. Investors pushed back on how much exposure Nvidia was absorbing for its biggest customer, and $130 billion of it came off the table.

From “could fall through” to a haircut

When the original talks surfaced in late July, the caveat attached to them was that the deal could still fall through. It did not. It got smaller, and it got staged: phase one is covered now, and the rest sits outside the current structure.

That is a meaningful distinction. A collapsed deal would have signaled that circular financing, in which the chip supplier bankrolls its customers’ demand, had hit a wall. A reduced deal signals that the model survives but is being marked to reality by the people who own Nvidia stock.

What it means for the buildout

Circular financing remains the load-bearing structure of the AI buildout, and Nvidia guaranteeing the leases that let OpenAI occupy a campus full of Nvidia chips is the clearest version of it. The cut shows where investors currently draw the line: $250 billion of contingent exposure for one customer was too much, while under $120 billion for one phase was acceptable.

Whether a smaller guarantee is good news depends on the vantage point. For Nvidia shareholders it is less concentrated risk on a single counterparty. For the buildout, it means the first phase of Piketon is funded and later phases will need backing that has not yet been described. The open question is whether other supplier-financed deals of this kind get the same treatment as investors apply the same scrutiny elsewhere.
