Here’s a pattern on PolyPunter. We comment on the 2028 Presidential election markets being so early in the process, not even any candidates declared for the race yet, and then something happens rather materially that we simply have to cover. Yes, even this early.
Gavin Newsom’s chances of winning the 2028 presidential election have plunged to a low on major prediction markets not seen really since the market first opened up last year, with traders driving his implied probability down sharply in recent days. This movement reflects growing skepticism, fueled by declining poll numbers among Democratic voters and shifting sentiment toward his national profile amid other recent political elections within his Party.
As contracts repriced late last week, Newsom fell behind both leading Republican figures in overall presidential winner markets. The decline highlights the challenges he faces in sustaining early momentum as he heads deeper into the cycle, now facing reduced odds of winning the Democratic Nomination for President, which, of course, is an absolute prerequisite to eventually winning the Presidency.
Market Data Reveals Steep Drop
Trading intensified around mid-to-late June as probabilities adjusted downward. On Polymarket, Newsom’s odds for capturing the White House in 2028 reached an all-time low of 12%, according to platform updates shared on June 29. Related Democratic nomination contracts show him near 20%, down from roughly 35% earlier in the year.
Current Odds Snapshot for 2028 Presidential Race
| Candidate | Approximate Probability | Platform Notes |
|---|---|---|
| Marco Rubio | 19% | Leading on Kalshi |
| J.D. Vance | 17% | Strong position across sites |
| Gavin Newsom | 12-14% | All-time low on Polymarket |
| Alexandria Ocasio-Cortez | 7-11% | Gaining in some segments |
| Jon Ossoff | 8-9% | Rising in nomination markets |
These figures, drawn from active trading on Polymarket and Kalshi, illustrate a fluid environment in which no single contender dominates. High volumes continue flowing through connected contracts as traders reassess long-term prospects.
Polls Track Closely with Market Adjustments
Survey data aligns closely with the downward pressure in trading. Support for Newsom among prospective Democratic primary voters dropped from 25% in January to 15% in recent readings. Nate Silver noted in his analysis that prediction markets have mirrored this trend, with nomination probabilities falling in tandem.
The convergence between polls and contracts adds credibility to the observed shifts. While the broader field remains open, these numbers signal that traders are assigning less weight to Newsom’s path forward than they did months ago.
Key Factors Contributing to Newsom’s Recent Slide
Several dynamics appear to weigh on trader sentiment. Newsom’s ties to the Democratic establishment draw scrutiny amid low favorability for recent party leadership. Public comments embracing aspects of the prior administration have not boosted his standing with primary audiences. It’s possible that the tide is shifting within his Party toward verified Democratic Socialist candidates, which, even if Newsom starts to signal allegiance with, may be tough for him to pull off given his 30-year in-office track record, which may say differently
A federal investigation into Newsom and his wife, announced around June 17, added another layer. He addressed the matter in a brief video, framing it as politically motivated. Mixed messaging on policy areas, including cultural issues, has further complicated his positioning. We know that Democratic Primary voters are driven as much, if not more, by “who can win the General Election” as by “who do I want to win the Primary”. In this case, any news items that appear to undermine his November 2028 electability will, in turn, reduce his numbers in the Primary itself.
Meanwhile, other contenders have contrasting profiles and are gaining ground within his own Party. Namely, AOC and Jon Ossoff, with the former already very high in national name recognition and Ossoff seen potentially in young Obama mold.
