Two Sigma raised pay in London last year but some people left
Two Sigma is looking to grow its London team in 2026; the hedge fund moved into a new office with double the floor space and room for up to 200 people. Accounts for 2025 filed via the UK's Companies House over the past week suggest it has to fill a few extra seats if it wants to pack that office out.

Headcount across both of Two Sigma's entities fell last year. 'Two Sigma International Limited,' its hedge fund entity, fell from 93 people to 85 through losses in both its modelling and engineering teams. 'Two Sigma Securities UK Limited,' the fund's market making arm, fell from 14 employees to 13 after one trader departed.
Spending on 'salaries and wages' was up in both entities. The hedge fund paid £502.8k ($681.5k) per head, while the market making arm paid £535.9k ($726.3k).
When Two Sigma first moved to its new office in Devonshire Square, it occupied one floor (roughly the same sized office as it previously occupied) and began refurbishing the floor above for them to occupy later. Estates Gazette said yesterday that it has officially leased that second floor and could be ready to unleash its hiring plans. At present, though, it only has one opening in operations and two in reliability engineering.
Squabbles atop Two Sigma's leadership team may also be a reason the fund has yet to push the button on hiring. Last month, Bloomberg reported that the fund sent a letter to investors notifying them that founders John Overdeck and David Siegel are going into another round of arbitration. The pair have had a public feud over the past few years that led to them resigning as co-CEOs in 2024.
