Collison's fortune is derived from his calculated 14% stake in closely held Stripe, which has raised about $1.6 billion from investors. The mobile payments startup received a $95 billion valuation during a March 2021 fundraising round but dropped about 33% by January 2023, according to a company statement and a Bloomberg News report. The valuation was updated on Jan. 12, 2023 to reflect the latest valuation for Stripe and this led to a decrease in the calculation of about $700 million.

Stripe's founders own 28% of the company, according to an analysis by Bloomberg News and Forge, a marketplace for shares in startups. Co-founders Patrick and John Collison are each credited with half of this stake to reflect their status as co-founders. A discount of 15% is applied to the valuation to account for the typical discounts applied to similar startups on the secondary market, according to two brokers who asked not to be identified as the information is private.

A Stripe spokesperson declined to comment on the Collisons' stakes.
