About the Company

Jane Street

Trades stocks, bonds and funds as a market maker

Jane Street trades stocks, bonds, options, and exchange-traded funds with its own money as a market maker, a firm that constantly quotes prices to buy and sell so other investors can trade whenever they want. In 2025, it made more money from trading than JPMorgan Chase or Goldman Sachs, the biggest trading banks on Wall Street. Its traders, researchers, and engineers build computer-driven strategies that trade on exchanges and other venues around the world, and it also trades directly with large institutional clients. It earns the small gap between buying and selling prices across huge volumes, plus gains on positions it holds for minutes to days. Jane Street was founded in 2000 and is based in New York.
