Ossoff Rockets, Rubio Closes, Newsom Fades: The 2028 Market Refuses to Pick a Winner
With over $1.4 billion wagered on the Democratic nomination alone, prediction markets can't agree on a 2028 frontrunner — and the numbers keep moving.

Two years before the first primary ballot is cast, the 2028 presidential race has produced more market movement than clarity. On both sides of the aisle, the past several months have reshuffled the board repeatedly — and the latest odds suggest neither party is anywhere close to settling on a standard-bearer.
The Democratic Market: A Three-Way Pileup at the Top
With over $1.4 billion in trading volume, the market for the 2028 Democratic presidential nomination is one of the most heavily traded political contracts in the world right now. The odds paint a portrait of a party genuinely unsettled about its next chapter.
California Governor Gavin Newsom sits atop the field at 18% in the cross-platform consensus — but that top-line number masks a dramatic slide. CNN chief data analyst Harry Enten noted on air this week that Newsom's market odds have "absolutely tumbled," falling sharply from where he stood at the beginning of the year when he commanded a far more commanding lead over the field.
The biggest mover has been Georgia Senator Jon Ossoff, now priced at 15%. Enten called Ossoff's rise "up like a Hotlanta rocket" on CNN Wednesday, citing his surge in prediction markets and a string of metrics pointing to growing national interest: Google searches for Ossoff are up roughly 300% year-over-year according to Enten's analysis, and he entered the month as the top Senate fundraiser this cycle, having raised $77 million through June 30, per Enten's reporting.
There is one notable wrinkle: Ossoff insists he is not a candidate. "I am not running for president in 2028. I have no interest in running for president in 2028," he told CNN flatly, adding that he is "laser focused" on his reelection bid in Georgia. He faces Republican Rep. Mike Collins in a race the Cook Political Report rates Lean Democrat. A recent AARP poll conducted by Fabrizio Ward and Impact Research (July 13–16, n=1,060 likely voters) showed Ossoff leading Collins 52%–43%.
Markets are, evidently, pricing in the possibility that Ossoff's mind could change — or simply that his reelection in a competitive swing state would make him impossible to ignore.
Representative Alexandria Ocasio-Cortez of New York is a tight third at 14%, having climbed from single-digit territory earlier this year. She has declined to rule out a run. Asked about a potential presidential campaign by journalist David Axelrod in May, she said: "My ambition is to change this country. Presidents come and go." When pressed more recently, she told Politico in June that she "can't say that I've ruled it out."
Former Vice President Kamala Harris holds 9%, reflecting her continued public activity after floating the possibility of another run in April. Pennsylvania Governor Josh Shapiro, former Transportation Secretary Pete Buttigieg, and Chicago Mayor Rahm Emanuel each sit around 5%. Kentucky Governor Andy Beshear and Arizona Senator Mark Kelly also register meaningful fractions of the field.
A recent Emerson College poll (July 19–20, n=574 Democrats, ±4 pts) offered a contrasting picture to the markets: it placed Buttigieg first among Democrats at 19%, followed by Newsom at 17%, with Ossoff and AOC tied at 13%. Notably, Ossoff was not included in a McLaughlin poll of general election voters (July 15–21, n=1,000), which showed Harris leading that survey at 28%, per Newsweek. The divergence between polling and prediction markets illustrates why neither should be read in isolation — polls measure declared preferences, markets price future outcomes.
No Democrat has formally declared a 2028 campaign.
The Republican Market: The Vance-Rubio Standoff
On the Republican side, Vice President J.D. Vance leads the nomination market at 41% — a commanding number, though the gap between him and Secretary of State Marco Rubio has narrowed considerably.
Rubio sits at 30% for the GOP nomination, a dramatic shift from his standing early in the Trump administration's second term. His ascent reflects a high-profile role managing multiple international portfolios — including U.S. operations in Venezuela and the ongoing Iran conflict — and sustained praise from President Trump, who has called him "the greatest secretary of state in history."
Both men publicly downplay any rivalry. Rubio has said that "if JD Vance runs for president, he's going to be our nominee, and I'll be one of the first people to support him." Vance has called Rubio "my closest friend in the administration." Trump, for his part, has called a Vance-Rubio ticket "unstoppable" while declining to specify who should lead it.
A University of New Hampshire Granite State Poll released July 24 showed Vance at 36% among likely GOP primary voters in the state, with Rubio at 26% — a significant compression from a prior February UNH survey in which Vance led 53% to 7%, per Fox News Digital's reporting on the poll. Rand Paul, Ron DeSantis, and Nikki Haley each registered at 6-8% in the UNH survey.
In our markets, the remaining GOP field barely registers: Ron DeSantis at 3%, Donald Trump Jr. and Trump himself at 3% each. The race, as of now, is a two-man show.
The General Election Picture
Zoom out to the full 2028 presidential election — all candidates, all parties, all outcomes — and the uncertainty compounds.
Vance leads at 19% in the general market, with Rubio close at 17%. On the Democratic side, Newsom checks in at 12%, Ossoff at 10%, and AOC at 9%. Harris holds 5%. No candidate has cleared 20%.
That kind of fragmentation — fifteen-plus candidates trading meaningful probability in the general election market, with the nominal frontrunner below 20% — is historically unusual this far out and signals genuine uncertainty, not just noise. The markets are pricing in the very real possibility that the 2028 race will hinge on events — a midterm result, a policy outcome, a candidacy announcement — that haven't happened yet.
For now, the $1.4 billion in the Democratic nomination market alone buys you a question mark with some well-known names attached.
