Summary
Jane Street has pulled ahead of Citadel Securities in per-employee compensation during the third quarter of 2025, marking a notable shift in the ongoing competitive dynamics between two of Wall Street's largest proprietary trading operations. According to Bloomberg reporting cited in eFinancialCareers, Jane Street increased its total compensation spending by 63% in Q3 to $1.94 billion. With a headcount exceeding 3,000 employees, this translates to roughly $609,000 per person over the three-month period.
By contrast, Citadel Securities reduced its Q3 compensation spending by 2.5% to $855 million across approximately 1,700 employees, averaging $502,000 per head for the quarter. This represents a 21% differential favoring Jane Street on a quarterly basis. However, context matters: Citadel Securities generated $2.64 billion in net trading revenue during Q3 (up 9% quarter-over-quarter), suggesting stronger profitability despite lower per-head compensation spending. Extrapolating full-year figures, Citadel Securities remains on track to average $2.1 million per employee for 2025, though compensation distribution within the firm is likely unequal.
The compensation competition reflects broader structural differences between the firms. Citadel Securities operates as a specialized market-making entity with a separately managed hedge fund (Citadel), while Jane Street functions as an integrated operation combining market-making with proprietary hedge fund activities. The sustainability of Jane Street's Q3 compensation surge remains uncertain; without full-year data, observers cannot determine whether the third-quarter surge represents a sustained shift or a seasonal anomaly.
Separately, Hudson River Trading has committed $1 billion to artificial intelligence development, underscoring sector-wide acceleration in technology investment. This capital allocation reflects competitive pressures to enhance algorithmic sophistication and operational efficiency across high-frequency trading platforms.
