Squarepoint, the quantitative hedge fund, is sometimes compared to Qube Research and Technologies. Both are run by the French. Both spun out of banks. Based on our admittedly partial visibility, though, it seems that people might leave Squarepoint more frequently.

Squarepoint’s past departures include Nathan Benabou, a top quant portfolio manager (PMs) who left in 2021 and joined Point72 in Dubai, and Khalil Bouchareb, one of Squarepoint’s top PMs, who went to Millennium in early 2025.
We understand that Benabou has left Point72 and is enroute elsewhere. Some members of his seven person team are understood to have left too, although some have been redeployed at Point72.
Similarly, we understand that Khalil Bouchareb will be leaving Millennium along with Antoine Le Calvez, a quant researcher who also formerly worked for Squarepoint. Bouchareb’s intention is unclear; it’s understood that he’s still at Millennium at the moment.
Point72 and Millennium declined to comment. Benabou didn’t respond to a request to comment.
Benhamou is thought to have been among the top performers at Cubist, Point72’s systematic investing business. Cubist has been through a few changes. In late 2025, Point72 hired Geoffrey Lauprete, the former CIO of WorldQuant to run Cubist, thereby displacing Denis Dancanet. It’s thought that Dancanet hired Benabou. Issam Bazzi, another senior quant on the team, was reported to leave in March. Lauprete has been hiring his own people to Cubist, including – most recently – John Koehl from Balyasny. Benabou’s departure may have been prompted by these changes.
Meanwhile, Squarepoint itself has been doing some hiring. Recent recruits to its team include macro portfolio manager Mark Orsley in New York (ex-BlueCrest) and Priyanka Chatterjee (ex-Verition). Squarepoint didn’t respond to a request to comment.
