The 2028 Democratic presidential nominee market is the largest political future listed on either exchange, carrying roughly $1.4B in cumulative volume across 58 priced contenders on Kalshi and Polymarket. No contender on the board has cleared 20c and the top three sit within a handful of cents of one another, so this is a field with a lead pack rather than a frontrunner. The live board above ranks the current cross-platform price on every name; the market resolves when the Democratic Party confirms its nominee at the 2028 national convention, expected in the summer of 2028.
The 2028 Democratic presidential nominee market is a long-dated futures contract with 58 priced contenders and roughly $1.4B in cumulative volume behind it, and its defining feature is that nobody owns it. No contender on the board has cleared 20c, and the three names at the top sit within a handful of cents of one another. That is a lead pack, not a frontrunner, and it is the honest read on a nomination that will not be settled for another two years. The live board above ranks every contender by current cross-platform price. This page covers who the field actually is, what structurally moves it, and exactly how it resolves.
Alexandria Ocasio-Cortez has moved to the front of the 2028 Democratic nominee board on both Kalshi and Polymarket, taking the position Gavin Newsom held through the first half of 2026. The structural case behind her price is the one no other contender can replicate: the largest small-dollar donor base in the party, the widest independent media reach of anyone in the field, and uncontested ownership of the progressive lane while the moderate lane splits six ways. Her contract is the cleanest expression on the board of where the party's activist energy sits heading into the midterms.
The counterweight is that she has never run a statewide or national race. The board is pricing reach and enthusiasm rather than a demonstrated ability to assemble a national primary electorate, and any nomination path runs through a contested primary calendar rather than a coronation. That gap between reach and proven coalition is the largest single source of disagreement on her contract, and it is why the two platforms have not settled on the same number for her.
Gavin Newsom carried the largest share of this board for most of 2026 and has since slipped back into the pack. The mechanical reason is that his platform is expiring. He is term-limited as governor of California and leaves office in January 2027, which removes the daily national megaphone that built the position in the first place. What he keeps is name recognition and the broadest donor network in the field, which is why he has not fallen out of the top tier.
Jon Ossoff is the contender with the most direct catalyst on the calendar. His Georgia Senate reelection on November 3, 2026 is a genuinely live race in a state that has trended back toward Republicans, and a win there is the cleanest 2028 credential anyone in the field can earn this cycle. It cuts the other way just as hard. A loss in November takes most of the case with it, which makes his contract the most binary position among the leaders.
Behind those three the field flattens fast. Kamala Harris carries residual national organization as the 2024 nominee and trades richer on Kalshi than on Polymarket, one of the wider platform disagreements on the board. Josh Shapiro and Pete Buttigieg lead the credible-but-unlaunched tier, followed by Mark Kelly, Rahm Emanuel, Andy Beshear, Wes Moore, Ro Khanna, J.B. Pritzker, and James Talarico in the low single digits. Below that sits a long tail of celebrity and novelty contracts, including Michelle Obama, Jon Stewart, Mark Cuban, and Stephen A. Smith, that absorb tens of millions in volume while pricing at or near zero. Volume on those names measures attention, not probability. The 2028 presidential election board is where the general-election matchups price instead.
The 2028 Democratic nominee market resolves to the candidate the Democratic Party formally nominates for president at its 2028 Democratic National Convention, expected in the summer of 2028. The nominee is determined by the pledged-delegate count secured through the primary and caucus calendar and confirmed by the convention roll-call vote. The winning contender's contract pays $1 per share while every other contender resolves to $0. The listed settlement date carries to the November 2028 general election as a buffer, but the outcome is fixed the moment the party confirms its nominee.
The 2028 Democratic nominee race is one leg of a much larger board. The 2028 Republican nominee market prices the other side of the ticket, and which party wins the 2028 presidency prices the general-election outcome directly. The Democratic candidacy market is the leading indicator for this page, since a contender has to actually enter before nomination odds mean anything, and it is the fastest place to see the celebrity names sorted from the real ones. The full slate of races sits in the politics market hub.
