**The Democratic vice-presidential nomination for 2028 remains highly fragmented in prediction markets, with no single contender exceeding low double-digit implied probability amid a wide-open presidential field.** Alexandria Ocasio-Cortez holds the top position at 10.5% due to her national profile as a leading progressive voice, strong small-donor base, and consistent media presence, even as she weighs a potential presidential or Senate bid. Governors such as Wes Moore, Gretchen Whitmer, Andy Beshear, and Josh Shapiro follow closely, reflecting trader emphasis on executive experience, swing-state or battleground records, and perceived ability to broaden geographic or demographic appeal. Other senators and figures trail as the eventual presidential nominee’s selection criteria—primary performance, endorsements, and 2026 midterm outcomes—will ultimately shape the ticket. No major candidate has declared, leaving room for shifts based on emerging coalitions or unexpected developments before the 2028 convention.
