- • Meiller previously ran a non-linear rates trading pod at Eisler and is expected to undertake similar responsibilities at Millennium, leveraging existing industry relationships including connections to Adrien Delattre, an equity vol portfolio manager who joined Eisler nine months prior.
- • The move represents a significant compensation upgrade: Millennium London partners earned an average of $5.6 million in profits last year, compared to $1.1 million average pay at Eisler in 2024—a roughly 5x differential.

Summary
Nicolas Meiller, a portfolio manager who exited the defunct Eisler Capital hedge fund in March 2025, has been hired by Millennium Management and elevated to partner status at the firm's London office. The move was confirmed through a Companies House filing identifying Meiller as a new member (partner) of Millennium Capital Partners LLP, and corroborated by his updated Bloomberg profile listing his affiliation with Millennium.
During his tenure at Eisler, Meiller operated a non-linear rates trading pod. At Millennium, he is expected to assume comparable responsibilities given his domain expertise. The hire reflects Millennium's continued recruitment of senior portfolio managers and suggests Meiller brings established expertise in interest rate derivatives and structured products—areas of focus within multi-strategy hedge fund operations.
The compensation structure underlying this transition is material. Partners at Millennium's London office earned an average of $5.6 million in annual profits in the previous fiscal year, substantially exceeding the $1.1 million average compensation at Eisler in 2024. This disparity underscores the financial motivation for mid-to-senior level talent migration from distressed or lower-performing funds to larger, better-capitalized platforms.
Meiller's professional network within Millennium extends beyond his pod—Adrien Delattre, an equity volatility portfolio manager, joined Eisler nine months prior, creating potential collaboration opportunities. However, administrative timing remains opaque: as of the reporting date, Meiller remained registered with the FCA as an Eisler employee and continues to list Eisler on his LinkedIn profile, suggesting either ongoing administrative processing or transitional registration periods that typically precede formal external announcements by hedge funds.
