Jane Street Group paid its employees about $9.4 billion last year, more than double the amount distributed the year before, as the secretive trading firm continued to convert market volatility into extraordinary profits. Bloomberg said the average payout worked out at roughly $2.7 million a head, underlining how far the firm has moved beyond its origins as a niche specialist.

That surge in compensation followed a record 2025 trading haul of $39.6 billion, according to Bloomberg, a figure that eclipsed major Wall Street banks and marked one of the strongest annual performances ever recorded by a market-making firm. In the final quarter alone, Jane Street generated $15.5 billion, while employing about 3,500 people, giving it a productivity profile that few rivals can match.

The company’s ascent has been built over more than two decades. Bloomberg reported that Jane Street began in 2000 trading American depositary receipts before expanding into exchange-traded funds and other electronically traded assets. As more markets became automated, the firm broadened into equities, bonds and a wider range of instruments, using quantitative trading systems and specialist hires drawn from mathematics, engineering and related fields.

Its balance sheet has also swollen. Bloomberg said Jane Street’s internal capital base has risen to about $45 billion, nearly twenty times its level a decade ago, giving it the flexibility to take larger positions without depending heavily on outside funding. The firm has also tapped debt markets, and that stronger financial footing has allowed it to invest beyond core trading, including stakes in private technology groups such as Anthropic and backing for CoreWeave, while exploring involvement with Fluidstack.

Even with its financial heft, Jane Street remains a highly unconventional powerhouse. The firm is run by partners rather than a traditional chief executive structure, and it has kept a low public profile despite growing scrutiny. Reuters has reported that it is defending itself against allegations in India over market manipulation and has also been drawn into litigation connected to the collapse of Terraform Labs. Yet the latest figures suggest the business continues to widen its lead, with expansion plans including a larger London office.
