Marco Rubio Favored on Kalshi to Win Presidency in 2028

Secretary of State Marco Rubio is seeing a rise in early indicators for the next presidential race, with both polling trends and prediction market activity pointing to increased momentum for the Florida Republican.

Rubio, who previously ran for president in 2016, has recently moved to the top spot on Kalshi’s market projections, with a 19% probability of winning the presidency, reflecting growing confidence among investors.

For months, expectations have centered on Vice President JD Vance as the leading Republican contender to follow President Donald Trump. Vance remains a strong presence in the market, currently holding 17% odds.

Just behind them is Gavin Newsom, with Kalshi participants assigning him a 16% chance of winning the presidency.

Further down the list are Jon Ossoff at 6%, Alexandria Ocasio-Cortez at 5%, and Kamala Harris, also at 5%.

Florida Gov. Ron DeSantis currently sits at 2%, though some observers suggest he could still attract interest as an underdog candidate.

Rubio’s improving position has coincided with his expanded role in the administration, where he has taken on a range of responsibilities and drawn attention for his composed and understated style.

Even with his gains in overall presidential projections, Rubio is still viewed as trailing Vance in the Republican primary contest. However, the difference between them has begun to shrink.

Vance continues to lead the GOP field with 38% odds, but Rubio has climbed to 27%, a significant jump from the single-digit range he occupied as recently as December 2025.

DeSantis also remains a distant contender in the primary outlook, holding at 4%.

President Donald Trump had previously signaled confidence in Rubio’s potential, remarking last year that a ticket featuring Vance and Rubio would be “unstoppable,” though he did not specify which of the two should lead it.
