The 2028 Republican presidential candidate field trades across roughly $355K in cumulative volume on Kalshi, pricing not who wins the nomination but who actually enters the race. A roster of more than 30 named Republicans splits the board, with the highest run probabilities sitting on J.D. Vance, Ted Cruz, Marco Rubio, and Ron DeSantis. The live board above ranks the current per-candidate odds of running; the market settles once the 2028 primary field is set in early 2028.
The 2028 Republican presidential candidate field is a market about entry, not victory. Each contract asks a single question for one named Republican, will this person actually run for president in 2028, and prices it independently, which is why the probabilities sum well past 100 percent: many of these candidates can run at once. That makes it a fundamentally different board from the nomination market, where the names compete for one prize and the prices sum toward a single winner. The live board above ranks every name by its current run probability; this page covers who the field is, what structurally moves each entry, and exactly how it resolves.
J.D. Vance sits at the top of the field as the candidate the market views as most likely to run, a standing that reflects his position as the sitting vice president and the structural expectation that the office is a launchpad. His price moves less on any single event than on the broad read of whether he positions himself as the heir to the current administration's coalition or steps back. Ted Cruz follows closely, a name with prior national-campaign experience and a Senate platform that keeps a 2028 run plausible in the market's eyes.
Marco Rubio and Ron DeSantis anchor the next layer of high-probability entries. Rubio's standing reflects an established national profile and a long-running presence in presidential conversation, while DeSantis carries the residual market weight of a prior campaign, a candidate who has run before is priced as more likely to run again. Both draw real volume on the board, and both sit in the band where the question is less "are they known" than "do they commit to a second or further run."
Below the top four, the field flattens into a long and crowded tail. Senators and governors such as Josh Hawley, Glenn Youngkin, Rand Paul, and Brian Kemp populate a middle tier where a single signal such as a campaign-style swing through an early primary state, a fundraising vehicle, or a pointed interview can move a price meaningfully because the baseline probability is low enough to be sensitive. Further down, the board prices a wide range of figures from across the party's media and movement wings, each with a thin but non-zero entry probability. The live board above is the only honest read on who is climbing and who is dormant across that tail.
The 2028 Republican presidential candidate field market resolves on a per-candidate basis once it is settled whether each named Republican has entered the 2028 presidential race. A candidate's contract pays out if that person formally launches a presidential campaign ahead of the 2028 primary season; it resolves to zero if the field is set without them in it. The market carries a listed settlement date in early 2028, around the start of the primary calendar, but each individual contract is fixed the moment that candidate's entry, or definitive non-entry, becomes clear under the platform's criteria.
The candidate field runs alongside the 2028 Republican nominee market, which prices who wins the nomination rather than who enters, the natural companion read to this entry board. The 2028 Democratic candidate field tracks the same entry question on the other side of the aisle, and the 2028 presidential party market prices which party wins the White House outright. For the full slate of election boards across both platforms, the politics markets hub tracks every race side by side.

Resolves on a per-candidate basis according to whether each named Republican enters the 2028 presidential race. An individual contract resolves YES and pays $1 per share if that person formally launches a 2028 presidential campaign ahead of the primary season under Kalshi's stated criteria; it resolves to $0 if the field is set without their entry. Because each candidate is priced independently, multiple contracts can resolve YES, this is an entry market, not a single-winner nomination market. The market carries a listed settlement date around the start of the 2028 primary calendar, but each contract is fixed when that candidate's entry or definitive non-entry becomes clear. Ambiguous or withdrawn candidacies resolve per Kalshi's platform-specific rules.
The live board above ranks each named Republican by their current probability of running for president in 2028, priced on Kalshi. The highest entry probabilities sit on J.D. Vance, Ted Cruz, Marco Rubio, and Ron DeSantis across a field of more than 30 names.
Each candidate's contract resolves once it is clear whether that person has entered the 2028 race, with a listed settlement date around the start of the primary calendar in early 2028. Because each name is priced independently, contracts can resolve at different times as candidates launch or rule out a run.
This market trades on Kalshi, which lists a separate run contract for each named Republican. The board above ranks every candidate's entry probability so you can compare the full field in one place.
The candidate field prices who enters the race — each contract is an independent yes-or-no on one person running, so the prices sum past 100 percent. The 2028 Republican nominee market prices who wins the nomination, a single-winner board where one name takes the prize.
Watch for formal campaign launches above all, since a declared candidacy resolves a contract toward payout. Then track early-state travel and fundraising activity from middle-tier names, whether the sitting vice president commits to a run, and any explicit decisions to sit out 2028.
