[AUM: $15B (public) | Pure Quant | Medallion Legend] [Good] Medallion Fund: $100B+ lifetime trading gains (employee-only). Institutional Equity Fund (RIEF) up 12.6% Q1 2025, crushing peers. Pure math/physics approach. 30+ year track record. [Bad] Medallion closed to outside investors. Limited public fund capacity. High fees. [Verdict] Most legendary hedge fund ever. Best for accessing top quant talent (though limited capacity).
