Cory Booker, a U.S. Senator from New Jersey since 2013, has been discussed as a potential presidential candidate in multiple cycles. The 2028 Democratic presidential nomination race remains wide open at this stage, with the formal nominee selection occurring at the Democratic National Convention in summer 2028. Delegates are determined through state primaries and caucuses held in the months leading up to the convention, and the final nominee is chosen by convention vote. The market resolution depends on whether Booker secures the nomination at the convention. At 1% YES odds, the market currently prices an extremely low probability that Booker will be selected, suggesting traders view other candidates, campaign momentum, polling dynamics, and establishment backing as more likely to produce the eventual nominee. In presidential nomination races, candidate viability historically shifts substantially as the election cycle progresses—early odds often shift significantly as campaigns develop, donor support emerges, and primary results clarify which contenders remain viable. This market provides a way to track the evolving probability of Booker's nomination prospects as the 2028 race unfolds.
