Summary
Ken Griffin, the billionaire founder and CEO of Citadel Advisors, has indicated a preference for Secretary of State Marco Rubio in the 2028 Republican presidential nomination race over Vice President JD Vance. According to reporting from Axios, Griffin made these remarks during a private conversation with financial journalist Andrew Ross Sorkin at the prestigious Allen & Company conference in Sun Valley, Idaho, stating he would be "predisposed" to support Rubio if the former sought the nomination.
Griffin's alignment with Rubio reflects consistency in his political positioning. The hedge fund manager previously backed Rubio during the 2016 GOP primary, establishing a pattern of support that he indicated would likely continue. His 2024 election cycle activity underscores his independent positioning within Republican donor circles: Griffin contributed $107 million to Republican-aligned PACs but notably withheld support from President Trump's campaign and MAGA Inc. super PAC, instead providing substantial financial backing to former U.N. Ambassador Nikki Haley as Trump's primary challenger.
The dynamics surrounding the 2028 succession remain fluid. Both potential candidates have strategically avoided committing to presidential bids. Rubio previously told Vanity Fair he would defer to Vance should the vice president pursue the nomination, while Vance stated in June that he would deliberate on a potential run with his wife, second lady Usha Vance, following the November midterms. Trump himself has not explicitly endorsed a successor candidate, though he privately suggested that a Vance-Rubio pairing would constitute a formidable ticket against Democratic opposition, with roughly 18 months remaining before the Iowa Republican caucuses.
Griffin's stated preference carries weight in Republican fundraising circles given his substantial capital deployment capabilities and demonstrated willingness to deploy capital independently of Trump's preferred candidates. His backing of Haley in 2024 despite Trump's eventual nomination indicated a degree of ideological or strategic divergence that may inform his 2028 calculations regarding Rubio over Vance.
