> The real money is at the top. The bond prospectus reveals that Jane Street has 40 “equity unit holders on a full-time basis and in good standing”, with an average tenure of 16 years. Among those there will be at least a handful of billionaires, even if no Jane Streeter appears on any rich lists.
Sounds like any other partnership. A few people at the top are providing the equity and getting a profit share, and the thousands under them are getting salaries.
