Nvidia plans $250bn guarantee for OpenAI data centre

Nvidia is in talks to provide a $250bn funding guarantee for OpenAI to lease a 10-gigawatt AI data centre in Ohio, being built by SoftBank's SB Energy. The total project could exceed $500bn, including $350bn in chips. Critics warn of circular financing, where Nvidia funds OpenAI to buy Nvidia chips, echoing the dot-com bubble. The deal reflects soaring AI infrastructure costs but raises concerns about genuine demand.
