Confidence rating:

Collison's fortune is derived from his calculated 14 percent stake in closely held Stripe, which has raised more than $1 billion from investors, according to Bloomberg News. The mobile payments startup received a $35 billion valuation during a September 2019 fundraising round.

Stripe's founders own about 28 percent of the company, according to an analysis by 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 percent is applied to the valuation to account for the typical discounts applied to similar startups attract on the secondary market, according to two brokers who asked not to be identified as the information is private.

No response was received to an e-mail sent to Stripe's press office requesting comment.
