The 2028 presidential election may still be more than two years away, but prediction markets are already positioning themselves for what could become one of the most competitive races we’ve seen.
Several high profile Democrats remain near the top of the market to win the party’s nomination, but few have seen the kind of momentum Jon Ossoff has generated over the past few months.
Gavin Newsom Still Leads the Field
California Governor Gavin Newsom remains the market leader with a 20 percent chance of winning the Democratic presidential nomination on prediction markets.
Although Newsom still sits atop the board, his position has weakened over time. At one point last year, traders gave him better than a 37 percent chance of becoming the nominee. As more potential candidates have emerged and political narratives have evolved, his market share has steadily declined.
Newsom remains one of the most recognizable names in the field, but traders appear less convinced that he is the clear front runner.
Alexandria Ocasio-Cortez Holding Strong
Representative Alexandria Ocasio-Cortez currently holds a 14 percent chance of securing the Democratic nomination, putting her in a tie for second place on prediction markets.
She continues to be one of the party's most recognizable progressive voices and has built a strong national profile over the past several years. Supporters point to her ability to energize younger voters, while traders continue to monitor whether that popularity can translate into a viable presidential campaign.
With the race still in its early stages, her position near the top of the market reflects continued interest from prediction market participants.
Jon Ossoff's Rapid Rise
No Democratic candidate has experienced a larger surge in recent months than Jon Ossoff.
The Georgia senator now sits at a 14 percent chance of winning the Democratic nomination after trading at just 1.5 percent in April. That dramatic increase makes him one of the biggest movers on the Kalshi board.
While there is still a long road before primary voting begins, traders have clearly become more optimistic about Ossoff's chances. Whether that momentum continues will likely depend on his public profile, fundraising, and the broader political environment heading into 2028.
For now, he has firmly established himself as one of the leading contenders.
Kamala Harris Falls Behind
Former Vice President Kamala Harris currently holds a 7.8 percent chance of earning the Democratic nomination.
After serving as the Democratic nominee in the 2024 election, Harris remains part of the conversation for 2028. However, prediction market traders currently give her significantly lower odds than several other potential candidates, placing her outside the top tier of the field.
As more candidates emerge and campaigns begin to take shape, her position on the board could continue to fluctuate.
The Trade Handle Prediction Markets Take
The biggest storyline in the Democratic nomination market is Ossoff's rapid climb.
While Newsom continues to lead the field, his odds have steadily declined as new contenders gain traction. Meanwhile, Ossoff has posted one of the largest increases on the board, jumping from just 1.5 percent in April to 14 percent today.
There is still plenty of time before the Democratic primary officially begins, and debates, fundraising numbers, endorsements, and the 2026 midterm elections will likely reshape the market several times over. Even so, prediction market traders are already signaling that Ossoff has become one of the names to watch.
With more than $143 million already traded in Kalshi's Democratic nominee market, the race is only beginning, and traders will continue searching for value as the political landscape evolves.
