Resolution criteria

This market resolves based on Bernie Sanders' public endorsement for the 2028 Democratic presidential primary. Resolution occurs on April 30, 2028 at 11:59 PM ET, or earlier. The market resolves to whichever answer matches Sanders' first public endorsement of a candidate in the 2028 Democratic primary, as reported by major news outlets. If Sanders makes no endorsement before the deadline, the market resolves to "No endorsement before April 30 2028." An endorsement includes official statements, campaign appearances, or direct participation in campaign materials. If Sanders endorses multiple candidates, the market resolves based on his first endorsement chronologically.

Background

Sanders recently turned 84 years old, and he has indicated he won't mount another presidential campaign in 2028, stating "I am 83 years of age. I'm not sure the American people would be too enthusiastic." Sanders has drawn massive crowds around the country with his "Fighting Oligarchy" tour alongside Rep. Alexandria Ocasio-Cortez, leading to speculation about his endorsement preferences.

Rep. Alexandria Ocasio-Cortez and her team are positioning her to run for president or the U.S. Senate in 2028, and some former aides to Sanders see Ocasio-Cortez as an heir apparent who could expand his appeal beyond the party's left wing. Ro Khanna's alliance with Sanders, whose 2020 presidential campaign he co-chaired, established him with the party's progressive activists, and Khanna is laying the foundation for a 2028 White House run.
