BEIJING, Oct. 27 (Bloomberg) — The IPO prospectus Anthropic disclosed on Monday shows that each of the company's seven co-founders holds about 1.4% of its shares, making each of them worth more than $13 billion.
The seven co-founders include Anthropic CEO Dario Amodei and his sister, President Daniela Amodei. All of them will rank among the top 300 on the Bloomberg Billionaires Index, with fortunes exceeding those of well-known financial billionaires such as Bill Ackman and Stan Druckenmiller.
These wealth estimates are based on Anthropic's $965 billion valuation in its last funding round, a sharp rise from Bloomberg's previous estimate of $8 billion per person. According to the Bloomberg Billionaires Index, if Anthropic succeeds in achieving at IPO the $2 trillion valuation target previously proposed by investors, each of them would see their net worth rise to more than $27 billion, excluding dilution from newly issued shares.
These founders' wealth highlights the absolute dominance of the tech sector, especially AI, in driving U.S. stock market gains and wealth creation this year. In the first nine months of 2026, the fortunes of tech billionaires among the world's 500 richest people rose by a combined $845 billion, while the average net worth of non-tech billionaires shrank.
