Nvidia to Backstop $250B for OpenAI’s Ohio AI Megacampus
2 min readThe AI arms race just took its most expensive turn yet. Nvidia is in talks to guarantee roughly $250 billion in financing so OpenAI can build a colossal data center campus in southern Ohio, a project that could ultimately cost more than half a trillion dollars. The Wall Street Journal first reported the discussions, and the sums involved dwarf almost any infrastructure deal the technology industry has seen.
What is being built
The campus is being developed by SoftBank’s energy unit and would eventually draw about 10 gigawatts of power, enough to rival the demand of a mid-sized city. The first phase, delivering roughly 800 megawatts of capacity, is expected to be finished by 2028. Full build-out could exceed $500 billion, making it one of the largest privately financed construction efforts in history.
OpenAI would lease the site rather than own it outright, a structure that lets the company add enormous compute capacity without carrying all of the debt on its own balance sheet.
Why Nvidia is involved
Nvidia would not simply write a check. Instead it would guarantee financing tied to the data center lease and construction debt, effectively lowering the risk for lenders and helping OpenAI borrow on better terms. Reports suggest a separate arrangement to finance the purchase of Nvidia chips could add another $350 billion on top of the $250 billion backstop.
For Nvidia, the logic is circular but powerful: backing the buildout locks in years of demand for its most expensive AI accelerators. Critics, including investor Michael Burry, have pointed to that circularity, noting the chipmaker is helping fund the very customers who buy its hardware.
Why it matters
July 2026 has made one thing clear: the AI story is no longer only about what models can do. It is increasingly about what they cost, who pays, and how the money flows between a handful of dominant players. A single financing package approaching the size of a national budget shows how capital, not just research, now defines the frontier.
The deal is not yet final, and terms could still shift. But if it closes, it would cement an Nvidia and OpenAI axis at the center of the industry and raise fresh questions about concentration and risk as spending accelerates.
