- • Chouvin's departure from Qube Research and Technologies follows four years at the Paris-based hedge fund, where he had joined in 2021 after spending over a decade at JPMorgan beginning in 2017.
- • Madhvani's pod, which focuses on index rebalancing strategies and employs approximately 30 people, is among Millennium's largest revenue generators, despite reporting a $900 million loss earlier in 2025.
- • Qube's bonus structure and multi-year deferral policy may have driven the departure, with the hedge fund deferring up to 75% of bonuses over three years, whereas Millennium employs a more formulaic compensation approach.

Summary
Philippe Chouvin, the former JPMorgan index swap trader and prominent fixture in quantitative trading circles, has completed his second major career transition by joining Millennium Management. Chouvin previously left JPMorgan in 2021 to join Qube Research and Technologies, the Paris-based hedge fund founded by former SocGen and Credit Suisse professionals. His new role places him within one of Millennium's largest operating pods, run by Pratik Madhvani from Dubai, though Chouvin is expected to maintain his base in Paris.
Chouvin brings substantial experience across major financial institutions, having worked for SocGen and Credit Suisse before his 2017 entry into JPMorgan, where he established himself as a leading index swap trader. His departure from Qube after four years reflects potential friction around compensation structures at the Paris-based hedge fund. According to multiple sources, Qube has faced criticism from former traders and portfolio managers for failing to deliver bonuses proportional to profit-and-loss generation and for implementing aggressive deferral mechanisms that lock employees' compensation for three years, deferring as much as 75% of bonus awards. Millennium's more formulaic compensation framework appears to have offered more attractive terms, with sources suggesting Chouvin's Qube bonuses may have been bought out as part of his recruitment package.
Madhvani's index rebalancing pod represents a significant revenue stream for Millennium despite recent volatility. The operation, which employs approximately 30 people, reported a $900 million loss earlier in 2025—a substantial drawdown that historically might prompt capital withdrawal from multi-strategy fund managers. However, Madhvani, alongside ex-Goldman Sachs VP Glen Scheinberg, remains among Millennium's top revenue generators and retains firm backing. The recruitment of Chouvin and at least one additional colleague from his prior professional circle underscores Madhvani's continued investment in team augmentation and operational expansion within the pod.
Both Millennium and Chouvin declined to comment on the transition, consistent with protocols around personnel announcements in the hedge fund industry.
