Nvidia halves its Ohio backstop, and the number was set by shareholders

Nvidia has reportedly cut the financing guarantee it was weighing for OpenAI's 10-gigawatt campus in Pike County, Ohio, from about $250 billion in late July to less than $120 billion ^[1][2][3]. The reason given is not a reassessment of demand for compute but investor concern about the financial risk Nvidia was absorbing, which is the first concrete number anyone has attached to the limit of vendor-financed AI capacity ^[4][5].

The structure matters more than the headline figure. On the source's account, Nvidia was never proposing to write a $250 billion cheque; it would guarantee financing arranged by lenders, which is what allows a borrower to raise large amounts of debt on terms it could not otherwise get ^[6][7]. The reason that backstop has value is that OpenAI does not carry an investment-grade credit rating ^[8]. Nvidia was, in effect, renting out its balance sheet as a substitute for one. Halving the guarantee halves how much of that substitute is available.

The cut removes more than $130 billion of proposed support, or over half the original figure ^[9]. Against an estimated project cost that could exceed $500 billion at full scale, the reduced guarantee now covers under a quarter of the build rather than roughly half ^[10][11]. That gap has to come from somewhere: other guarantors, equity, or a smaller campus.

The separate piece is still large. Nvidia is discussing an arrangement involving as much as $350 billion in AI chips for the facility, kept distinct from the guarantee, and under that structure Nvidia supplies hardware rather than funding construction ^[12][13]. The chip deal is now close to three times the size of the trimmed guarantee ^[14]. That asymmetry is the tell. Nvidia remains willing to be the seller of record at enormous scale; it is less willing to sit behind the lenders when the asset is a construction site in southern Ohio.

The physical project is unchanged for now. SB Energy, SoftBank's energy subsidiary, is developing the campus, with a first phase of about 800 megawatts targeted for 2028 ^[15][16]. That first phase is 8 percent of the announced 10-gigawatt figure, and the remainder depends on years of further construction and power infrastructure ^[17][18]. At full scale the site could host hundreds of thousands of advanced AI processors ^[19]. Terms of the Nvidia arrangement remain under negotiation and nothing final has been announced ^[20].

What to watch: whether the missing $130 billion of credit support reappears from another party or quietly shrinks the scope; whether the $350 billion chip arrangement gets the same investor scrutiny the guarantee just received; and whether the 800-megawatt 2028 milestone slips, since it is the first date on this project that can be checked against concrete rather than press releases ^[9][12][16].
