2028 Democratic Nominee Odds: The Market's 5-Cent Blind Spot

If you play DFS or draft fantasy teams, you already know this market's shape, even if you have never traded a political contract. The 2028 Democratic nominee board on Kalshi is the largest open market on the exchange, roughly 175 million contracts traded across 47 candidates, and it behaves exactly like a preseason futures board: a crowded field, no candidate above 17 cents, and a price on every name from a sitting governor to LeBron James. We handed the full board to a seven-model AI panel, price-blind, with a card carrying every national and statewide 2028 primary poll from the last 90 days, each candidate's current office from structured sources, and the contract's exact settlement language. Then every seat read the others' anonymized reasoning and revised. The market and the panel agree the race is wide open. They disagree, by triple, on who the favorite is.

The Quick Answer

The market's top three are Gavin Newsom at 16.5¢, with Jon Ossoff and Alexandria Ocasio-Cortez at 14.5¢ each. The panel's blend, after a revision round, makes Pete Buttigieg the favorite at 15.8%, a name the market sells for 5.45¢. Every single seat priced Buttigieg above his market price, and every seat priced Ossoff, the market's co-second-favorite, at 6.5% or less. Whether the machines or the money are right about that double disagreement is what this page tracks through settlement, and the model-by-model board is below.

The Market

Each contract resolves YES if that person is the first to be nominated by the Democratic Party for the presidency in 2028 and to accept the nomination; the market closes early once that happens at the convention, and the listed expiration is November 7, 2028. The 47 contracts are mutually exclusive, and there is no field contract: a nominee who is not listed means every contract on the board settles NO. That structural gap matters, because the 47 midpoints currently sum to about 102 cents, which leaves roughly nothing for anyone Kalshi has not listed. The panel put 5% on exactly that.

Two timestamps for the record: panel verdicts were generated the evening of August 9, 2026, price-blind; prices were fetched from the exchange at 19:52 UTC the same evening. Kalshi is a CFTC-regulated event-contract exchange; 18+, availability varies by state as of August 2026.

How A Projections Reader Prices A Race Like This

Here is the translation layer for anyone who has ever compared average draft position to a real projection. A national preference poll 27 months from a convention behaves like preseason ADP: it measures how often a name comes to mind, not how the race plays once matchups start. A likely-voter poll in an early state is closer to a slate-level projection: smaller sample, noisier, but measuring the thing that actually decides outcomes first. The card handed to the panel contained both layers, all 27 national polls from the last 90 days and every statewide poll in the window, with each pollster's graded historical accuracy attached, and the two layers disagree hard.

Nationally, Kamala Harris leads nearly every poll in the card, printing anywhere from 19 to 44 percent where she leads. But in the two New Hampshire polls in the card she prints 5 and 4, and in the freshest Michigan poll, fielded July 25-29, she prints 5.1. Pete Buttigieg is the mirror image: he leads or co-leads all four early-state prints in the card (21 and 29 in New Hampshire, 19 and 24.2 in Michigan) while typically sitting third or fourth in the national prints. He is also the only candidate in the card's window with an explicit intent signal, saying on August 3 that he is "more inclined than not" to run. Every seat on the panel read that split the same way, and the market, on this one name, apparently does not.

"That gap is the classic signature of residual name ID from a prior national campaign rather than durable primary-electorate strength." (Claude Opus)

Where The Machines Split From The Money

Pete Buttigieg: Market 5.45¢, AI Blend 15.8%

The widest panel-over-market gap on the board, and the most uniform: all seven seats landed between 14.5% and 17%. The case was identical seat to seat, early-state leadership plus the only stated intent to run.

"He is not merely polling nationally in the top tier, he leads both New Hampshire polls at 21% and 29%, leads the newer Michigan addendum at 24.2%, and has the only explicit recent intent signal in the card, saying on 2026-08-03 he is more inclined than not to run." (ChatGPT)

The honest caveat came from the same seats that made him favorite: he holds no current office, and, as one seat put it, "small-state retail polling is exactly where he over-performed in 2020 without converting." (Claude Opus)

Jon Ossoff: Market 14.5¢, AI Blend 4.7%

The widest market-over-panel gap. The market prices the Georgia senator as co-second-favorite; no seat gave him more than 6.5%. The panel saw the same riser signal the market sees, 13 in Emerson's national poll and 13.9 in the new Michigan poll, but discounted it because his Senate term ends in January 2027, which puts a November 2026 campaign between him and any 2028 launch. The market is paying for the surge now; the panel wants November's evidence first.

Alexandria Ocasio-Cortez: Market 14.5¢, AI Blend 9.0%

She owns the best New Hampshire prints on the board, 22 and 17, and the panel priced that. What capped her at 9 was structure, not polling: a House platform has historically been a thin launch pad for a nomination, and several seats applied the same discount to her early-state strength that they applied to Harris's national numbers.

Kamala Harris: Market 9.45¢, AI Blend 12.4%

The one name the panel priced meaningfully above the market. The seats discounted her national leads hard, but most kept her above 10 on the logic that a candidate who still starts at 30 in unaided national recall retains a real path if she runs.

Rahm Emanuel: Market 4.55¢, AI Blend 0.54%

The board's quietest trap. The market pays the former Chicago mayor and ambassador the same price as Josh Shapiro, a sitting swing-state governor; the panel's blend puts them nine-tenths of a point and six points apart, respectively. No seat found a polling fact in the card to support the price: he prints between zero and 2 percent in the handful of national polls that offer him.

Where The Panel Changed Its Mind

Every seat read the other six's anonymized round-one reasoning, then could hold or revise with a stated reason. The revision round cut the panel's disagreement on Buttigieg by two-thirds (the seat-to-seat spread fell from an 11.8-19.0 range to 14.5-17.0) and produced the run's biggest single move:

"I hold close to the panel consensus, which converged sharply across seven independent forecasters on the same structural read." (Claude Sonnet, moving Harris from 22 to 15 and Buttigieg from 12 to 17 on the national-versus-early-state split)

"I therefore join the Buttigieg-first cluster... but hold him at 15, not 19: he holds no office, and one unrated Michigan pollster (PSI) drives part of his case." (Kimi K3, which also cut Harris from 16.3 to 10.1)

One seat pushed back on the convergence itself and kept a split ticket:

"I hold a co-favorite top rather than following the panel's convergence onto a single Buttigieg lead." (Claude Opus, keeping Newsom and Buttigieg level at 14.5)

Dark Horses The Panel Won't Dismiss

• Gretchen Whitmer (0.95¢, blend 3.3%): the cheapest sitting-governor contract on the board relative to the panel's number. One seat's summary: "zero bad prints and a swing-state governor's platform but no breakout poll yet." (Claude Sonnet)
• Andy Beshear (3.55¢, blend 3.2%): "a sitting two-term red-state governor who appears in nearly every national poll at 2-8.5%, the classic late-consolidation electability profile." (Kimi K3)
• Zohran Mamdani (0.25¢, blend 0.67%): "sitting mayor of New York City since 2026, the largest municipal platform in the country, absent from poll answer lists so his support is unmeasured rather than zero." (Kimi K3)
• James Talarico (1.65¢, blend 0.44%): "the card lists him as the 2026 Democratic Senate nominee in Texas; a November win would instantly make him a national figure before the 2028 cycle starts." (Kimi K3)

What Would Change The Panel's Mind

• The November 2026 midterms. The single trigger most seats named. Ossoff's Georgia result either validates the market's 14.5¢ or ends it; Talarico's Texas race and every sitting governor's margin re-rank the second tier overnight.
• Harris formally in or out. Multiple seats wrote that her announcement, either direction, moves more probability than any other single event: roughly a tenth of the board redistributes.
• A Buttigieg formal launch. The panel already paid his August 3 lean; a declared campaign converts the early-state pattern from suggestive to structural.
• The DNC's 2028 primary calendar. The card deliberately excluded the unset state order. Whichever state goes first decides whose early-state polling matters; a calendar decision re-scores this board immediately.

Settlement Timeline

• November 3, 2026 — midterm elections; the first hard evidence that re-ranks this field.
• 2027 — declared candidacies arrive; polls shift from name recognition toward real preference.
• Summer 2028 — the Democratic National Convention selects a nominee; the market closes early when the nominee accepts.
• November 7, 2028 — listed contract expiration.
• This page re-scores when the story moves; prices above are as of August 9, 2026, 19:52 UTC.

How To Read These Prices

• Eligibility. Kalshi is a CFTC-regulated event-contract exchange, not a sportsbook. 18+, availability varies by state as of August 2026.
• No field contract exists. The panel's 5% on an unlisted nominee is a probability you cannot buy; its tradable meaning is that a board summing to 102 cents is collectively rich.
• A 27-month clock. This market's biggest risk is time, not information. Prices here move on news cycles years before settlement, and a position carries opportunity cost the whole way.
• Not advice. These are model estimates, not predictions of fact and not financial advice.

The Bottom Line

The market and the panel agree this is the most open Democratic field the exchange has ever priced, and they disagree about what openness means. The market spreads its money across the famous names: Newsom, Ossoff, and Ocasio-Cortez carry 45.5 cents between them. The panel, reading the same polls with the name-recognition layer stripped out, concludes the race's most undervalued asset is the one candidate leading where nomination races are actually decided first, and prices him at triple his market cost. In a fantasy draft this is the classic ADP-versus-projection gap, and the panel just published its projection. The nomination will grade it in public.
