Anthropic's seven co-founders join top billionaires with $13 billion fortunes

Anthropic’s IPO filing shows its seven co-founders each hold about 1.4% of the company, valuing them at more than $13 billion apiece based on a $965 billion valuation. That places them among the top 300 on the Bloomberg Billionaires Index and ahead of some finance billionaires. If Anthropic reaches a $2 trillion IPO valuation, each founder’s stake would exceed $27 billion before dilution. All seven pledged to donate 80% of their personal equity to philanthropy.
