This marks the first evaluation of the wealth of the 38-year-old by the index.

Altman emerged as a prominent figure in artificial intelligence due to his position as CEO of OpenAI, a company recently valued at $86 billion.

Bloomberg reported that he has iterated that he does not own equity in OpenAI.

The report added that a greater part of his traceable wealth is in a network of Venture capital (VC) funds and start-up investments.

Altman's wealth is expected to increase with the upcoming initial public offering of Reddit, where he holds a major stake as one of the largest shareholders, the report said.

In a separate development, Tesla CEO Elon Musk has filed a lawsuit against OpenAI and Sam Altman, alleging a breach of contractual agreements dating back to 2015 when Musk offered support in founding the ChatGPT-maker.

According to the lawsuit filed on Thursday in San Francisco, Altman and OpenAI's co-founder Greg Brockman initially approached Musk intending to create an open-source platform.
