President Trump has privately signaled support for Vice President JD Vance as a 2028 successor while publicly stating it remains “way too early” for any endorsement, instead highlighting a potential contest with Secretary of State Marco Rubio. Recent remarks to donors and subsequent clarifications show no formal commitment, with advisers describing the choice as unsettled amid 2026 midterm priorities and administration business. Traders view a public endorsement before 2027 as unlikely absent a major shift, consistent with historical patterns of late-cycle positioning by sitting presidents and the absence of scheduled events that would force an earlier decision.
