Basically any established HFT, though they're market making instead of market taking. TGS. Baupost. Soros had an excellent run for like 30 years. Simons' family office, Euclidean, does well. A lot of under the radar family offices which don't have stringent reporting requirements. Various groups in Citadel, Point72 and Millenium. Appaloosa. A bunch of prop trading groups in the Chicago area. And outside of quant, the top long/short equity funds regularly do well. Like Coatue.
