Two Sigma London average pay rises to about £503,000

Accounts filed with UK authorities show Two Sigma International’s London business reported average salaries and wages of about £503,000 for 2025, up roughly 34% from £377,000 in 2024.

Headcount at that legal entity fell to 85 from 93 over the same period. The filings note the decline applies to that specific company and does not necessarily mean employees left Two Sigma overall; some roles may have been moved to other London entities.

A separate London company, Two Sigma Securities UK, which handles proprietary trading and market-making activities, reported average pay of about £608,000 and employed 14 people in 2024. Its most recent accounts have not yet been filed.

Two Sigma has continued to recruit in London. The firm moved into a new office near Liverpool Street in March, taking one floor initially while refurbishing another for future use. Current job listings in London include positions at Two Sigma Securities UK, with listings describing the business as entering a period of growth.
