Summary
Yiming Zhang, a top quantitative researcher with 17 years of tenure at Jump Trading Group, has resigned from the systematic trading firm and secured backing from Millennium Management to launch an external trading venture. According to Business Insider reporting, Zhang is expected to become an external manager for Millennium on an exclusive basis once his non-compete obligations expire.
Like many secretive quant trading firms, Jump Trading enforces lengthy non-compete provisions that can extend up to two years for non-executive staff, creating a waiting period before former employees can operate independently or for competing platforms. This structural constraint is standard across the industry and applies to Zhang's transition.
Zhang was a central figure at Jump Core Strategies, one of Jump Trading's largest and most profitable operating units. His departure was accompanied by that of Darko Kirovski, another senior researcher at the same division. Jump cofounder Paul Gurinas issued a statement characterizing both individuals as "instrumental in Jump's growth over the last 17 years," signaling their strategic importance to the firm's operations.
The arrangement between Zhang and Millennium Management exemplifies a broader shift in hedge fund compensation and talent acquisition models. Rather than recruiting external talent into permanent roles, major funds increasingly structure deals where specialized researchers operate as external managers or satellite teams, providing access to differentiated trading strategies and expertise while maintaining operational flexibility. Millennium, which manages $84 billion and operates hundreds of internal teams across multiple hedge fund strategies, appears positioned to benefit from Zhang's quantitative research capabilities and track record.
Neither Millennium nor Jump Trading provided additional commentary beyond existing statements. Zhang did not respond to requests for comment, and Kirovski's post-departure plans remain undisclosed.
