Ken Griffin Says He Would Support Marco Rubio in 2028 GOP Primary

Thursday, July 9, 2026 · 3 sources

Republican megadonor Ken Griffin stated he would support Secretary of State Marco Rubio over Vice President JD Vance in a 2028 GOP presidential primary. Griffin is one of the most prolific donors in the Republican Party, having given more than $100 million in 2024.

Ken Griffin, a major Republican donor, said at a private conference that he would support Secretary of State Marco Rubio over Vice President JD Vance in a 2028 GOP presidential primary. Griffin made the comments at the exclusive Allen & Company conference in Sun Valley, Idaho, in response to a question from New York Times financial columnist Andrew Ross Sorkin. Griffin noted that he has historically backed Rubio, including during his 2016 presidential run, and would be predisposed to backing him again.

Griffin's comments reflect an emerging split in the GOP between establishment-minded figures who want Rubio to run and anti-establishment types who prefer Vance. Rubio has said he would defer to Vance if the vice president runs in 2028, as Vance is widely expected to do. Griffin, a billionaire investor, has criticized President Trump in the past and supported former U.N. Ambassador Nikki Haley over Trump in the 2024 GOP primary.

Griffin's support would be a significant asset to Rubio if he were to run for president. Griffin gave more than $100 million in 2024 and is considered one of the most prolific donors in the Republican Party. A Griffin spokesperson declined to comment on the matter.
