Summary
Two Sigma has substantially elevated compensation levels at its London operations, with average salaries and wages at Two Sigma International reaching approximately £503,000 in 2025, representing a 34% year-over-year increase from £377,000 in 2024. The increase was achieved despite a reduction in overall headcount at the entity, which fell to 85 employees from 93 in the prior year. The figures, disclosed in accounts filed by Two Sigma International, underscore the premium that quantitative investment firms continue to place on specialized talent in London's competitive financial services market.
Two Sigma International provides investment management and administrative services to several of the firm's hedge funds and affiliated investment companies. The decline in headcount does not necessarily indicate a net reduction in the firm's London footprint, as some departing employees may have transferred to other Two Sigma entities within the capital. The firm operates a separate business, Two Sigma Securities UK, which focuses on proprietary trading and market-making activities and paid average compensation of approximately £608,000 across 14 employees in 2024, indicating that trading-focused roles command substantially higher compensation than administrative and management positions.
Despite organizational adjustments, Two Sigma has signaled continued commitment to its London operations. The firm relocated to a new office near Liverpool Street in March 2026, initially occupying one floor while refurbishing additional space for potential future expansion. The company is currently advertising multiple open positions in London, including roles at Two Sigma Securities, which has characterized itself as entering a period of growth. This expansion activity suggests that compensation increases may be paired with selective hiring in specialized skill areas, consistent with broader industry trends among quantitative hedge funds competing for elite technical talent in major financial centers.
