Nvidia weighs $250bn guarantee to anchor OpenAI's Ohio megacampus

Nvidia is reportedly considering a $250 billion lease guarantee to underpin OpenAI's occupation of SoftBank's planned 10-gigawatt Ohio data centre, alongside a separate $350 billion chip financing arrangement. The scale of the deal would make it one of the largest single infrastructure commitments in corporate history, cementing Nvidia's role as the financial backbone of the AI buildout — not just its hardware supplier. Political resistance is already forming, with several US states proposing bans on new data centres.
