Nvidia: $250B OpenAI Backstop for Ohio Data Center

Nvidia is in talks to provide a roughly $250 billion backstop for OpenAI as part of a 10-gigawatt data center campus in southern Ohio developed by SoftBank's energy subsidiary, with total project costs including chips potentially exceeding $500 billion and marking the largest such announcement to date; the backing would improve debt terms for the developer given OpenAI's lack of investment-grade rating, though no terms are finalized.
