Ken Griffin, CEO of Citadel and a prominent GOP billionaire, reaffirmed his commitment to relocating his firm from New York City to Miami, citing a preference for a state that is more supportive of business interests [1]. During an interview at the Allen & Company conference in Sun Valley, Idaho, Griffin was questioned by Andrew Ross Sorkin about whether he would support Secretary of State Marco Rubio or Vice President JD Vance in a hypothetical 2028 Republican presidential primary. Griffin stated that he had previously backed Rubio and would be inclined to do so again, though he did not specify the nature of any potential support [1].
Axios reporter Alex Isenstadt highlighted that Griffin had previously urged former President Donald Trump not to select Vance as his 2024 running mate, as detailed in Isenstadt's 2025 book, 'Revenge: The Inside Story of Trump's Return to Power' [1]. Griffin's political contributions in recent years include a $5 million donation to a super PAC supporting Nikki Haley during the last GOP presidential primary, as confirmed by his spokesperson and reported by The Associated Press. After the 2024 general election, Griffin stated that he voted for Trump [1].
On the other hand, Rubio has publicly stated that he would not challenge Vance if Vance decides to run for president, expressing his support for Vance's potential candidacy according to a 2025 Vanity Fair report [1]. Griffin, who is the founder and CEO of Citadel, has an estimated net worth of over $51 billion, according to Forbes [1].
Fox Business reached out to Citadel for additional comment, but no further statements were provided in the article [1].
CONCLUSION
Ken Griffin's comments suggest a continued preference for Marco Rubio in future GOP presidential primaries, though he stopped short of detailing specific support. The news is unlikely to have a significant market impact, as it centers on political endorsements rather than direct business or financial developments.
