Vance Extends Lead in GOP Odds as Rubio Holds Second: What the Markets Are Signaling for 2028

The GOP nomination markets continue to consolidate around JD Vance, who now sits near 39%, widening his advantage over Marco Rubio at roughly 29%. Former President Trump’s odds remain low—hovering around 5%—as bettors increasingly treat the race as a two‑man contest.

The shift reflects two forces: Vance’s growing national profile and Rubio’s steady but less dynamic support. Meanwhile, long‑shot candidates like Ron DeSantis, Nikki Haley, and Glenn Youngkin remain in the low single digits, suggesting the field is unlikely to expand meaningfully.

If these odds hold, the GOP primary could become one of the earliest “locked‑in” nomination battles in recent cycles. But with debates, fundraising reports, and early‑state polling still ahead, markets may continue to adjust.
