Kenneth C. Griffin

Griffin is a fascinating figure because he started trading from his Harvard dorm room and turned that into one of the most dominant forces in modern finance. Citadel and Citadel Securities together touch an astonishing share of US market activity, which makes him both deeply respected and, in some corners of the retail-investor world, deeply distrusted, especially after the GameStop saga thrust him into the spotlight. I find his record genuinely impressive on the numbers, even if his outsized influence over market structure raises legitimate questions. His art purchases and political donations alone could fund a small country. Love him or not, he's a heavyweight.
