Jane Street, the quantitative trading powerhouse that most people outside finance have never heard of, now employs roughly 3,500 people. And it wants 500 more before the year is out.
To put that in perspective, the firm generated around $39.6 billion to $40 billion in trading revenue in 2025. Do the math on 3,500 employees and you get an average compensation figure of approximately $2.7 million per person. That’s not a typo.
From small prop shop to global giant
Jane Street started in the late 1990s as a small proprietary trading group. Now it operates across more than 200 trading venues globally, providing liquidity in equities, ETFs, fixed income, and increasingly, digital assets.
The growth trajectory here is striking. Previous estimates pegged the firm’s headcount somewhere between 3,000 and 3,300 employees in 2025. Reaching 3,500 and planning to add another 500-plus signals that leadership sees room to run, not consolidate.
The hiring push spans trading, technology, research, and infrastructure roles. Positions are open across global offices, with notable expansion in Hong Kong and London.
The crypto angle
For crypto-native readers, Jane Street’s expansion matters because the firm is increasingly a player in digital asset markets. Its JCX platform facilitates around-the-clock trading in actively traded cryptocurrency tokens.
That said, the firm has scaled back certain US crypto activities since 2023 amid regulatory pressures.
Jane Street is currently facing legal challenges related to allegations of insider trading connected to the 2022 Terra/Luna collapse. Lawsuits filed in 2026 claim misconduct by certain traders at the firm during the implosion that wiped out tens of billions of dollars in value across the crypto ecosystem.
Jane Street has denied these allegations.
What this means for crypto investors
The presence of firms like Jane Street in crypto markets brings tighter spreads, deeper order books, and more efficient price discovery. It also brings sophisticated strategies that can make it harder for smaller traders to find edge.
When Jane Street, Citadel, and their peers compete for the same pool of quantitative researchers and engineers, compensation spirals upward. That talent drain affects every adjacent sector, including crypto-native firms that need the same skill sets but can’t necessarily match $2.7 million average compensation packages.
For the crypto market specifically, the legal proceedings around Terra/Luna bear monitoring. If courts establish that major market makers had material non-public information during the 2022 crash, it could reshape how regulators approach market-making in digital assets going forward.
