Gretchen Whitmer, Michigan's governor, has been mentioned as a potential 2028 Democratic presidential candidate alongside other state-level executives and federal leaders. The Democratic Party will nominate its 2028 presidential candidate at the Democratic National Convention scheduled for August 2028. At current odds of 1%, the market implies traders assign relatively low probability to Whitmer's nomination compared to other prospective candidates. The resolution criteria center on whether Whitmer receives the party's formal nomination at the convention—a binary event determined by delegate votes. Her nomination prospects depend on multiple factors including primary election results, delegate allocation, party support, and overall political climate through 2028. The market pricing reflects expectations formed from early polling, media coverage, fundraising activity, and historical precedent for candidate viability. Trading volume on this question ($42,568 over 24 hours) and available liquidity ($589,800) provide depth for participants seeking price discovery. The question resolves definitively after the August 2028 Democratic National Convention concludes its nomination process, with resolution based on official convention records and media confirmation of the nominated candidate.
