Trader consensus on Polymarket favors Robert F. Kennedy Jr. at 49% implied probability for the 2028 Republican presidential nomination, reflecting his recent endorsement of Donald Trump, alignment with America First priorities on health policy and government reform, and appeal to independent voters amid Trump's 2024 landslide victory. J.D. Vance, at 36.8%, gains as vice president-elect and heir apparent in the MAGA movement, bolstered by his Senate tenure and campaign trail visibility. Marco Rubio's 22.1% share rises following his nomination as secretary of state, signaling Trump's trust and positioning him for a potential primary run. Post-election transition developments, including cabinet announcements and no clear incumbent path due to term limits, drive early speculation on Trump's successors, with upcoming 2026 midterms likely to sharpen contours.
