Jane Street generated $39.6 billion in trading revenue in 2025, marking a record year for the firm, according to people with knowledge of the results who asked not to be named while discussing confidential figures. The company recorded $15.5 billion in revenue in the fourth quarter of the year.
For the full year, Jane Street’s revenue exceeded that of a major U.S. bank by roughly 11% while operating with a headcount of about 3,500 employees. On that basis, the firm produced in excess of $11 million of revenue on average per employee.
Profits at the firm were supported by two primary factors, the people said. First, rising valuations of the firm’s holdings in privately held companies contributed to an increase in reported profit. Second, Jane Street’s core business of matching buyers and sellers across asset classes benefited from elevated market volatility during the period.
On an adjusted basis, earnings before interest, taxes, depreciation and amortization for 2025 amounted to about $31.2 billion, according to the same people. Those adjusted results reflect the combined effect of trading revenue and valuation moves in the firm’s private-company stakes.
Context and implications
The figures underscore the scale of revenue a trading-focused firm can generate under conditions that combine active markets and favorable valuation changes in private holdings. Jane Street’s reported performance highlights two distinct revenue drivers: transactional activity that captures bid-ask spreads and liquidity flows, and mark-to-market gains tied to private equity holdings.
While the company’s headcount remains relatively small compared with larger universal banks, its per-employee revenue metric is notably high, reflecting the capital- and technology-intensive nature of its operations and the outsized revenue streams in 2025.
Clear summary
- Jane Street posted $39.6 billion in trading revenue for 2025, with $15.5 billion in the fourth quarter.
- Adjusted EBITDA for the year was about $31.2 billion.
- Revenue per employee exceeded $11 million, derived from total headcount near 3,500.
Key points
- Record annual trading revenue of $39.6 billion and a strong fourth quarter of $15.5 billion point to an exceptional year for the firm.
- Growth in profits was supported by valuation gains on stakes in privately held companies and by trading activity that benefited from market volatility.
- The firm generated more than $11 million in revenue per employee while surpassing a large U.S. bank's full-year revenue by about 11%.
Risks and uncertainties
- Valuation sensitivity - reported profit gains included surging valuations of private-company stakes, which may be volatile and subject to reversal.
- Market-dependence - the core matching business benefited from market volatility; a sustained decline in volatility could weigh on transactional revenues.
- Concentration of output - high revenue per employee reflects concentrated operational scale, which could imply operational or staffing-related sensitivities.
