Ken Griffin
Corporate-libertarian GOP mega-donor. Not Israel-focused — foreign policy is not his explanatory variable; tax, antitrust and education reform are.
Who they are.
Founder and CEO of Citadel, the multi-strategy hedge fund and Citadel Securities, the market-making giant. The largest single Republican mega-donor of the 2024 cycle by some accounts. Unlike Adelson or Singer, Griffin's giving is primarily framed around corporate-tax, antitrust, financial-deregulation and education-reform interests — not foreign policy.

Questions about Ken Griffin.
Is Ken Griffin pro-Israel?
Griffin has paused Harvard donations citing the campus response to Oct 7, 2023, but his political giving is not primarily framed around foreign policy. Public reporting from OpenSecrets, the NYTimes and WSJ describes his donor priorities as corporate tax, financial deregulation, antitrust, and education reform. He is included in this registry as breadth coverage — not all mega-donors share the same foreign-policy variable.
How much did Griffin give in 2024?
Griffin's 2024-cycle giving was reported in the $100M+ range by OpenSecrets and the WSJ, making him among the largest single donors of the cycle. Most flowed to Senate Leadership Fund, Congressional Leadership Fund, and Trump-aligned vehicles after Ron DeSantis withdrew.
What is Citadel?
Citadel is a $60B+ multi-strategy hedge fund founded by Griffin in 1990. Citadel Securities, his separately operated market-making firm, executes a major share of US equity-options retail order flow. Griffin's personal wealth derives primarily from Citadel and Citadel Securities.
