SoftBank Group’s 10-GW AI data-center campus in southern Ohio is progressing under a phased plan that targets an initial 800-MW segment by 2028. The site, developed by SB Energy on the former Portsmouth Gaseous Diffusion Plant, has a total cost exceeding $500 billion. In July 2026, negotiations intensified regarding financing. Nvidia confirmed it is negotiating a financing guarantee of roughly $250 billion to back the lease and construction debt for the campus. Because OpenAI lacks an investment-grade credit rating, the guarantee is intended to reassure lenders. A separate hardware package for GPUs, potentially totaling up to $350 billion, remains under discussion. By August 2026, Nvidia expanded its strategy by entering into memorandums of understanding with six major financial institutions—Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs, and KKR—to mobilize over $500 billion in third-party capital. Nvidia stated it could backstop up to $125 billion of this target, representing approximately 25% of the goal. ~~This platform aims to treat AI computing as a long-term revenue-generating infrastructure asset.~~ Nvidia has since revised its financial commitment to address investor concerns, reducing its financial guarantee from the initial $250 billion to less than $120 billion to cover only the first phase. To protect against potential defaults or insolvency by OpenAI, Nvidia committed to providing residual value guarantees for the initial buildout, capped at $105 billion. Additionally, Nvidia has provided over $105 billion to secure physical requirements for OpenAI’s planned PORTS-Pike Technology Campus in Ohio, including land acquisition, power procurement, and building shells. Nvidia also finalized a $1.5 billion equity investment in SB Energy to facilitate these developments. Recent developments indicate Nvidia is in talks to invest up to $3 billion in SB Energy, potentially split between the signing of the Ohio project deal and SB Energy’s anticipated initial public offering.
