Who Will Win the Republican Primary?
Republican primary prediction markets track the odds for each potential nominee, providing a continuously updated picture of the race that adjusts to polling, endorsements, fundraising, debate performances, and campaign developments.
Primary markets are particularly valuable because traditional polling often struggles to capture the dynamics of multi-candidate fields, caucus states, and delegate allocation rules. Prediction markets account for all of these factors, including the strategic withdrawals and endorsements that often determine the outcome.
The markets below show current odds for each candidate. Track how the odds shift as the primary campaign develops and key states approach.
