Summary
Two Sigma's leadership dispute widened on April 1, 2026, when co-CEO Scott Hoffman resigned from the quantitative hedge fund, according to Pensions & Investments. Hoffman's departure was reported as the latest development in a feud between the firm's co-founders, John Overdeck and David Siegel, that has disrupted management since 2024.
According to publisher context, Hoffman cited "ongoing governance challenges" following Overdeck's return to Two Sigma's management committee. Two Sigma has reportedly disclosed new details about the disputes between the co-founders alongside the resignation.
Overdeck and Siegel stepped down as co-CEOs in August 2024 amid feuding that one report described as causing "management dysfunction." Since September 30, 2024, the firm has been led by co-CEOs Carter Lyons and Scott Hoffman, while Overdeck and Siegel remained co-chairmen. Hoffman's exit after less than two years in the role leaves Lyons as the remaining co-CEO in the reporting available.
An earlier co-chief appointed to quell the dispute had also quietly resigned, citing the same governance issues, according to publisher coverage. Two Sigma Investments, which publisher context places at roughly $70 billion in AUM, is one of the larger quantitative managers, and the continuing instability is likely to draw attention from allocators monitoring key-person and governance risk.
