Donald Trump told donors privately that he wants JD Vance to win the 2028 presidential race, according to The Washington Post. The Vice President, a former Ohio senator, is already positioning himself as the Republican frontrunner, but Trump hasn't made any public statement yet.

The private nod matters less without a formal endorsement. Prediction markets currently price Vance leaving office before year-end at just 5.5%, a modest shift from earlier readings. Party insiders read it as a signal, but the market impact stays muted until Trump goes public.

What changes the calculus: a formal Trump endorsement, or moves from other Republican heavyweights backing Vance openly. With 147 days left until the December 31 deadline for Vance's VP role, traders will watch for any crack in his standing with Trump or shifts within the party hierarchy. Those signals could swing the odds significantly.
