Democratic presidential nominee 2028 predictions: Who leads the field?

Kamala Harris leads national Democratic primary polls, but prediction markets aren't following her lead. Jon Ossoff, Gavin Newsom, and Alexandria Ocasio-Cortez have higher prices in OG's 2028 Democratic presidential nominee market.

The gap raises an interesting question about the race. Are voters sticking with a familiar name while traders expect someone else to emerge? With the first Democratic primary scheduled for January 2028, the race is still wide open.

What are the 2028 Democratic nomination predictions?

Ossoff, Ocasio-Cortez, and Newsom are trading within a few percentage points of each other, while Harris is further back. 

National polling looks quite different. Harris holds a double-digit lead over Newsom, while Pete Buttigieg polls ahead of both Ocasio-Cortez and Ossoff.

For example, a Yes contract priced at 21¢ suggests roughly a 21% market-implied chance of Ossoff securing the nomination. If he wins, the contract settles at $1. If he doesn't, it settles at $0, subject to the market rules.

The prediction market prices reflect trading activity, not a poll of Democratic voters. They can move as the field develops, and trading involves risk.

Jon Ossoff

Jon Ossoff has another election to get through before 2028. The Georgia senator is seeking reelection this November, nearly six years after winning his seat in a January 2021 runoff.

His Senate campaign puts him back in the national spotlight. Georgia has been closely contested in recent federal elections, and the result could influence how Democrats view his political future.

For now, Ossoff leads our Democratic presidential nominee 2028 market at 21%, even though he draws just 8.6% in national primary polling. His immediate priority, however, is holding onto his Senate seat.

Gavin Newsom

California Governor Gavin Newsom has made himself one of the Trump administration's most prominent Democratic critics. He's also campaigning for Democrats outside California ahead of the midterms, putting him in front of voters who could matter in a future presidential primary.

Newsom polls at 14.4% nationally, second only to Harris, while our nomination prediction market puts him at 18%. His national political activity has attracted attention, although he hasn't announced a presidential campaign.

Alexandria Ocasio-Cortez

Alexandria Ocasio-Cortez has built a following far beyond her New York congressional district through her progressive positions and outspoken criticism of Republican policies.

The question for a potential presidential campaign is how that support translates across the Democratic electorate. Her nomination contract is priced at 17% on OG, while her national polling average stands at 11.1%, behind Harris and Newsom.

Kamala Harris

Harris is first in the polls, but not in the market. She has one advantage her potential rivals can't claim: she's already run for president as the Democratic nominee.

Her 2024 campaign gives her nationwide name recognition and an established network of supporters. But another run would also raise questions about what she could do differently after losing to Trump.

National polling still puts Harris ahead at 25.9%, although individual surveys vary. She received 38% in September's Harvard-Harris poll but just 19% in October's Echelon Insights survey.

Harris hasn't ruled out another run. She's campaigning for Democrats ahead of the midterms, including stops in Nevada and New Hampshire, both early states on the 2028 primary calendar.

For now, her 10% price in our Democratic presidential nominee 2028 predictions market is well below her standing in national polls.

Other 2028 Democratic primary candidates to watch

Pete Buttigieg polls at 12.9% nationally, but his support is considerably stronger in New Hampshire. An October survey put him at 28%, making him a potential contender worth watching when the early primaries begin.

Josh Shapiro governs Pennsylvania, a state both parties have fought hard to win in recent presidential elections. Andy Beshear has twice won the governorship in heavily Republican Kentucky. Their records offer different perspectives on how Democrats might appeal to voters outside the party's traditional strongholds.

Mark Kelly, a US senator for Arizona and former astronaut, also features in early nomination polls, averaging 6.5% nationally.

Polls vs. prediction markets 2028

Harris leads national polling by 11.5 percentage points. Yet, as we’ve seen, several other Democrats have higher prices in our Democratic presidential nominee 2028 market.

Polls ask people which candidate they currently prefer, usually from a list of potential contenders. Prediction markets ask a different question: who will win the 2028 Democratic nomination?

That leaves room for very different results. Someone might name Harris in a poll today while a trader expects Newsom or another Democrat to attract more support once campaigning begins.

The gap can also reflect uncertainty over who actually runs. Some candidates may enter the race, while others decide against it.

What early polls can and can't tell us

Early polls can show name recognition and existing voter support. They can also change considerably as voters hear more from candidates.

Recent polling illustrates this. Harris received 38% in the September Harvard-Harris survey but 19% in the October Echelon Insights poll. Different samples and survey methods can produce quite different results.

Prediction-market prices can also be misleading when trading activity is low. A few transactions may have an outsized effect on the displayed probability.

Historical research has found that election prediction markets can outperform polls in some forecasting periods, although much of that work concerns general-election vote shares rather than presidential nominations years in advance. It doesn't establish that today's prices accurately identify the eventual 2028 nominee.

How the 2028 Democratic primary calendar works

South Carolina kicks off the 2028 Democratic primaries on January 22. The Democratic National Committee (DNC) approved six early states in August 2026, adding New Mexico and Virginia to the lineup.

The early contests could give lesser-known candidates a chance to challenge the national frontrunners, particularly if they perform better than expected in South Carolina or New Hampshire.

How the Democratic nomination process works

Candidates compete for delegates through state primaries and caucuses. Democrats use proportional allocation, meaning qualifying candidates can share a state's delegates rather than the winner taking them all. A candidate needs a majority of delegates to secure the nomination.

The party also has automatic delegates, known as 'superdelegates.' Their voting rights depend on convention rules, which can limit their participation in the first ballot.

What could reshape the 2028 Democratic field?

The next major event on the political calendar is the November 3, 2026 midterm election. Its results could influence which Democrats receive greater national attention before the presidential primary campaign begins.

Several developments are worth following:

• The 2026 midterms: Candidates campaigning in competitive races could gain exposure before 2028.
• Campaign announcements: The field could change significantly once prominent Democrats confirm whether they're running.
• Fundraising: Candidates need financial support to build campaign organizations and compete across multiple states.
• Endorsements: Support from influential party figures could help contenders attract attention and organize voters.
• Early-state results: Strong performances in the first primaries could change polling and nomination-market prices.

Harris is already visiting early primary states, while Ossoff is focused on his Senate reelection campaign. Other potential contenders are also supporting Democrats in the midterms.

Once candidates begin formally entering the race, voters and traders can assess actual campaigns rather than hypothetical ones.
