Miami, Florida — Billionaire hedge fund manager Ken Griffin has contributed $10 million to U.S. Representative Byron Donalds’ campaign for Florida governor, a sum described as instantly transforming the financial contours of the race. Griffin, the CEO of Citadel and one of the country’s most influential Republican donors, has aligned his considerable resources with Donalds, a prominent conservative and key ally of former President Donald Trump. The eight-figure check gives Donalds a powerful early advantage in the competition to lead Florida after Governor Ron DeSantis leaves office, strengthening his position as a leading contender in the developing field. The $10 million infusion provides Donalds with the ability to dominate television and digital advertising, expand campaign infrastructure and signal viability to other potential donors and supporters. In the context of state-level politics, such a large single contribution represents the capacity for sustained outreach and an aggressive media presence across Florida’s major markets. Griffin’s backing, rooted in his status as a major Wall Street figure, underscores the national attention on Florida’s upcoming gubernatorial transition and highlights the growing role of big-money donors in shaping the early trajectory of high-stakes statewide contests.
