OpenAI is in advanced talks to anchor a $500 billion data-center campus on roughly 3,700 acres of Energy Department land in Ohio, drawing 10 gigawatts of power, with Nvidia and SoftBank's SB Energy as partners, The Information reported [1][2]. Days after filing confidentially to go public, the company's physical expansion now runs through a federal land lease and supplier credit.

The number that matters is not the $500 billion. It is the 10 gigawatts. The paper's June 15 reporting on how Nvidia's 10-gigawatt promise keeps OpenAI inside a power ledger treated that figure as a pledge. Ohio gives it an address, acreage and named partners. Ten gigawatts is roughly twice the entire current data-center load of Northern Virginia, the equivalent of about ten large nuclear reactors, or enough to power seven to eight million homes [1].

That is the part both sides skip. You cannot pull 10 gigawatts off any existing American grid segment; the campus is as much a generation project as a computing one, and the capital for power alone—a mix of gas, nuclear and renewables—likely exceeds $15 to $20 billion [1]. Where that generation comes from decides whether the cost stays inside the fence or spreads, the same question driving the household-cost fight the paper covered in states repricing data centers. Nothing in the reporting yet says who builds the power, on what timeline, or at what price [2].

This is the concrete form of a pledge built in public. Last September, Nvidia said it intends to invest up to $100 billion in OpenAI as systems deploy, with the first gigawatt due in the second half of 2026 [3]. That is also the part X fixes on: money Nvidia puts into OpenAI returns to Nvidia as chip orders, recording as demand what is partly financing. On federal land, the loop now runs through a government landlord and a supplier willing to bankroll its biggest customer [2].

The skepticism is fair, but the capital is visibly arriving. The same week brought a $35 billion private chip-debt package for Anthropic from Apollo and Blackstone and a fresh Google data-center expansion [2]. The mainstream covers the address and the acreage; X compresses it into the circular-financing chart. Neither has answered the only question a 10-gigawatt campus cannot defer: who pays for the power, and whether the grid the rest of us share helps cover it.
