The question surrounding the next Democratic presidential contest is not yet who will win the nomination, but who will decide to seek it. Reporting identifies a broad set of possible contenders, including governors, a former vice president, senators and Pete Buttigieg. But a list of potential candidates is not the same as a field of declared candidates: the cited report says none of the prospective candidates it discusses had formally entered the race.
Kalshi’s market records traders’ current beliefs about individual people running; it is not an objective forecast or a complete account of the field. At as of 10:00 a.m. ET on Sept. 28, the market places Alexandria Ocasio-Cortez at 62%, Pete Buttigieg at 91%, and Andy Beshear at 84%. Gavin Newsom and Rahm Emanuel are each at 83% and 83%, respectively. J.B. Pritzker, Cory Booker and Josh Shapiro are at 80%, 80% and 80%. These are candidate-by-candidate contracts, not portions of a single field that must add up to one: more than one person could run, and the market’s roster does not establish who will.
The activity figures vary across those contracts. Kalshi recorded 1,913 contracts traded over the last day for Ocasio-Cortez over the last day, compared with 6 contracts traded over the last day for Buttigieg and 0 contracts traded over the last day for Newsom. The market also lists 64,826 contracts open for Ocasio-Cortez and 32,248 contracts open for Newsom; open interest describes contracts still open, not trading during the last day. The listed weekly changes for Ocasio-Cortez and Booker were up 0 points over the week and up 2 points over the week. These measures describe market activity and trader beliefs. They do not confirm a candidacy, explain a person’s intentions, or establish that political developments caused a market movement.
The reporting offers different indications about possible bids. Ocasio-Cortez said her immediate focus was helping Democrats win in 2026, while playing down speculation about a future presidential bid. Buttigieg has not ruled out a White House bid, according to the cited report, while Harris has said she has not decided whether to run again. Those accounts do not amount to announcements. A high price in a contract about running should not be read as proof that the person has committed to a campaign. The report’s prospective-candidate list is a snapshot, not a settled account of who will ultimately consider or enter the race.
Reporting identifies AI development, regulation and datacenter construction as emerging issues among potential Democratic contenders. A cited poll found opposition to datacenter construction at 61%. The finding provides context for one issue potential contenders are addressing; it does not establish what any particular person would do. The market, meanwhile, tracks beliefs about who will run, not positions on these issues or who will win the nomination. Its prices are not objective chances, and the available claims do not settle which potential contenders will make a formal bid. The central question—who will choose to run—remains unresolved in the reporting and in the market’s candidate-by-candidate prices.
