Nvidia is also in talks to provide roughly $250 billion in financing guarantees for OpenAI as part of a massive data center project, the Wall Street Journal reported on Sunday.

The backstop from Nvidia would help the ChatGPT maker lease a 10-gigawatt project that SoftBank's energy subsidiary is developing in southern Ohio, the newspaper said, citing people familiar with the matter.

For OpenAI, a deal would be the first step toward controlling its own infrastructure instead of renting it from Microsoft, Amazon and Oracle, while for Nvidia, it would guarantee demand for its chips for years to come.

The project is expected to cost more than $500 billion in total, including the chips inside the data center, according to the Wall Street Journal.
