Jane Street posts $39.6B trading revenue

Jane Street generated a record $39.6 billion in net trading revenue in 2025, overtaking major Wall Street banks and its biggest high-speed trading rivals. (money.usnews.com) (bloomberg.com) Bloomberg reported the firm made $15.5 billion in the fourth quarter alone. Reuters reported Jane Street’s annual total topped JPMorgan Chase’s $35.8 billion trading revenue for the year. (bloomberg.com) (money.usnews.com) Reuters said Jane Street had about 3,500 employees when it posted those results. That is a fraction of the headcount at universal banks whose trading desks sit inside much larger lending and advisory businesses. (money.usnews.com) Jane Street is not a household-name bank. It is a private quantitative trading firm that makes markets by standing ready to buy and sell exchange-traded funds, equities, bonds, options, commodities and currencies. (janestreet.com) (money.usnews.com) That business tends to swell when markets swing hard. Reuters said 2025 volatility helped market makers and bank trading desks alike as investors rushed to hedge risk and reposition portfolios. (money.usnews.com) Jane Street’s edge was not only fast trading. Reuters said gains on stakes in private startups, including artificial intelligence company Anthropic, also boosted profit, alongside a unit that invests across a company’s life cycle. (money.usnews.com) Reuters reported Citadel Securities posted about $12.2 billion in trading revenue in 2025, while Hudson River Trading posted about $12.3 billion. On that measure, Jane Street’s result was more than triple either rival’s. (money.usnews.com) The numbers are surfacing through private-market reporting because Jane Street does not publish open investor materials the way listed banks do. Its investor-relations page says annual and quarterly reports are available only to noteholders, prospective investors and qualified analysts under confidentiality restrictions. (janestreet.com) Jane Street declined to comment to Reuters. The firm’s latest record shows how far non-bank trading houses have moved into territory once dominated by the biggest Wall Street dealers. (money.usnews.com)
