OpenAI Chief Executive Sam Altman has recently met with major investors in the Middle East to raise capital for a new funding round totaling at least $50 billion, sources familiar with the matter said.

Altman’s meetings included discussions with some of Abu Dhabi’s largest sovereign funds. The company is reportedly seeking to raise $50 billion or more at a valuation of roughly $750 billion to $830 billion. Sources cautioned that the talks are in the early stages and the final amount could change.
