It’s still three years away, but gamblers have already coalesced around a clear favorite to win the 2028 Republican presidential nomination, according to one betting market.

But Polymarket data shows gamblers believe the runaway leader for the GOP nod will lose in November to a Democrat.

Vice President JD Vance has a massive 48-point lead over Secretary of State Marco Rubio — who is in second place on Polymarket — with 56% to Rubio’s 8%.

No other potential GOP contender is above 5%; President Donald Trump, although constitutionally barred from serving a third term, is at 5% along with Florida Gov. Ron DeSantis.

Donald Trump Jr., the president’s eldest son, is next at 4%, with Virginia Gov. Glenn Youngkin at 3%.

The Democratic side, where there is no clear party leader, is more competitive.

California Gov. Gavin Newsom leads the pack at 21%, followed by Rep. Alexandria Ocasio-Cortez of New York at 16% and Biden Transportation Secretary Pete Buttigieg at 12%.

No other potential Democratic candidate hit double digits.

After Buttigieg are a quartet of Democratic governors: Kentucky’s Andy Beshear at 8%; Pennsylvania’s Josh Shapiro at 6% and Michigan’s Gretchen Whitmer and Maryland’s Wes Moore at 5%.

Also at 5% is 2024 Democratic nominee and ex-Vice President Kamala Harris.

While Vance has a large lead among Republicans, bettors do not believe the GOP will take the White House in November 2028.

Asked which party will win the 2028 election, the Democratic Party leads the Republican Party, 55% to 46%.
