Nvidia is in talks to invest as much as $3bn in SB Energy, the SoftBank Group subsidiary developing the planned OpenAI data centre campus in Ohio, according to a report carried on the wire on 15 August.

Read the structure before the headline

The $3bn is doubly conditional. Half would land when the Ohio project deal is signed — and it has not been. The other half would come as part of SB Energy's planned initial public offering — which has not happened. SB Energy is aiming to list as soon as next month and could raise at least $5bn. Neither Nvidia nor SB Energy commented; the requests went out outside business hours.

A backstop is not capex

In the same negotiation Nvidia is discussing around $100bn of credit support for the campus. That is a guarantee Nvidia would stand behind, not money Nvidia would spend — so "Nvidia invests $120bn in Ohio" is simply wrong. And the direction of travel matters: the Wall Street Journal reported the guarantee is now expected to cover under $120bn initially, down from $250bn previously discussed. The number is shrinking, not growing.

What is actually new today

Only the $3bn equity line — roughly 1% of the other figures in the same paragraph. The guarantee cut was reported the previous day and belongs to that day's story, not this one.

Why a chip vendor is buying into a power developer

The campus is a 10 GW build on US Department of Energy land in Pike County, Ohio, with a separate GPU financing arrangement of as much as $350bn under negotiation. Taking equity in SB Energy puts Nvidia on the cap table of whoever controls the electrons rather than only in the supply chain for the racks — and it does so days before that developer asks public markets for $5bn on the strength of the same campus.
