- Will Trump endorse JD Vance for president before 2027?5¢5%
President Donald Trump’s recent public refusal to discuss or commit to endorsing Vice President JD Vance for the 2028 Republican nomination has reinforced trader expectations that no early endorsement will occur before 2027. In an October 20 Oval Office exchange, Trump described Vance as talented and capable but stated the two had never discussed the topic, calling it premature and directing focus to the November midterms. Vance has voiced confidence that Trump would eventually back him if he runs, while acknowledging the possibility of a contested primary and the value of allowing candidates to compete independently. Trump has previously labeled Vance his “most likely” heir apparent yet has also highlighted other figures such as Secretary of State Marco Rubio, maintaining flexibility ahead of the 2028 cycle. These signals align with the 94.9% implied probability on “No.”
