Summary
Jian Wu, a 34-year-old former Senior Vice President at Two Sigma, one of the financial industry's most prominent quantitative hedge funds, was indicted on September 11, 2025, on charges of securities fraud, wire fraud, and related offenses. The charges were filed simultaneously by the U.S. Attorney's Office for the Southern District of New York (SDNY) and the Securities and Exchange Commission (SEC), marking a significant enforcement action against a high-level executive in the quantitative finance sector.
According to the SDNY and SEC charging documents, Wu allegedly abused his senior position at the hedge fund to manipulate proprietary data models used in investment decision-making. The manipulation resulted in Wu securing an undeserved multimillion-dollar award through unlawful conduct. FBI Assistant Director in Charge Christopher G. Raia stated that Wu "allegedly abused his position to manipulate data models, which resulted in an undeserved multimillion-dollar award for his unlawful actions." The alleged scheme represents a breach of fiduciary duty and investor trust at a firm that manages billions in assets.
Wu began employment at Two Sigma in 2018. Two Sigma, headquartered at 100 Sixth Ave in SoHo, was co-founded in 2001 by David Siegel and John Overdeck and has become a leading player in algorithmic and quantitative investment strategies. Wu, described as an Ivy League-educated computer science and mathematics genius originally from China, lived in the Kent Building, one of Manhattan's most prestigious Upper East Side addresses. Federal authorities are moving to seize his luxury real estate holdings as part of the enforcement action.
Wu is currently a fugitive, with federal authorities seeking his apprehension. The case represents one of the more significant fraud allegations to emerge from the quantitative finance community in recent years and underscores potential vulnerabilities in oversight of senior technologists with access to proprietary trading models and data systems.
