CoinVoice recently learned that according to financial reports, OpenAI CEO Sam Altman has invested in more than 400 companies and holds shares worth at least $2.8 billion. It is reported that Altman's net worth recently exceeded the $2 billion mark. He does not hold shares in OpenAI and his annual salary at the company is about $65,000, but Altman is one of the most prolific individual investors in Silicon Valley. Altman's investment companies include payment company Stripe, short-term rental platform Airbnb, social news forum Reddit, and Musk's brain-computer interface company Neuralink.

Regulatory documents show that Altman's traceable net assets mainly include three parts: venture capital fund projects, listed companies, and estimated investment returns. Most of them come from investments in a series of venture capital funds, totaling up to $1.2 billion. [Original link]
