Ken Griffin - Citadel Advisors
Ken Griffin founded Citadel in 1990 and built one of the world's most successful multi-strategy hedge funds (and, separately, the major market-maker Citadel Securities). Its 13F reflects a vast, diversified book including heavy market-making and options activity.
Ken Griffin - Citadel Advisors manages a $618B U.S. equity portfolio of 6,733 positions, based on the latest SEC Form 13F-HR filing (Q1 2026). Below you'll find its 100 largest holdings, the biggest quarter-over-quarter buys and sells, position weights, and an estimated average buy price.
This is a market-maker, quant, macro-ETF, or broad-mandate filer. Its 13F reflects trading and inventory — often dominated by index ETFs and option notional — rather than conviction stock-picking, so it's excluded from the site's Combined AUM, Consensus Picks, and Biggest Moves. The portfolio value below is the total value reported on the 13F.
