Jane Street Capital is an American multinational quantitative trading firm headquartered in New York. It employs approximately 3,000 people across its global offices, located in New York, Singapore, London, and Hong Kong.[4]
Jane Street originally traded American depositary receipts (ADRs), but has since traded exchange-traded funds (ETFs), commodities, index, fixed income, and derivative products.[5][6] The firm does not maintain a standard management structure, with its workforce and leadership co-operating like an “anarchist commune”.[5]
History
Jane Street was co-founded by Tim Reynolds, Robert Granieri, Marc Gerstein, and Michael Jenkins in 1999. Reynolds, Granieri, and Jenkins were former traders at Susquehanna International Group, while Gerstein was a developer at IBM.[7] Jane Street was sued by Susquehanna for poaching top talent with proprietary information, but no action has been taken since the filing.[7] Granieri is the only founder still at the company, as of 2026.
Leadership culture
The company is informally led by a group of 30 or 40 senior executives and has historically not maintained a CEO.[5] All employees are paid based on the firm's collective profits, not personal trading gains.[8]
In 2025, Jane Street employs approximately 3,000 employees, with its headquarters located in New York City’s Financial District's 250 Vesey Street.[9][10]
In November 2020, Jane Street hosted a market prediction competition with a $100K prize pool that ran until August 2021.[11] The stock trading data in the Jane Street dataset provided for this competition has been used in research studies aimed at improving trading decision-making.[12]
Trading activities
Jane Street traded ADRs before moving into equity options and ETFs, with ETFs becoming the main focus. [15] Throughout the late 2000s, Jane Street started trading fixed income, futures, commodities, and equity options.
Jane Street is not known for creating detailed year-long plans.[6] Instead, Jane Street expands into neighboring markets incrementally. In the second quarter of 2025, Jane Street reported $10.1 billion in net trading revenue and $6.9 billion in net profit, setting a record for the highest trading revenue in a quarter. [16] In 2024, Jane Street averaged $2 trillion in equity trading volumes per month. [17]

Controversies
London Metal Exchange lawsuit
In June 2022, Jane Street and Elliott Investment Management sued the London Metal Exchange for cancelling US$4 billion in nickel trades during a period of high volatility.[21] The case was dismissed by the High Court of Justice in November 2023,[22] and an appeal to the dismissal was rejected in October 2024.[23] The Financial Conduct Authority later fined the London Metal Exchange in March 2025 for mishandling the excessive volatility.[24]
