Live prediction market odds for "Which of these Democrats will be the first to announce a run for President?". Pete Buttigieg leads at 33.8%. Next is Rahm Emanuel at 22%. $107K has traded across 14 outcomes on Kalshi and Polymarket. The market is expected to resolve by Jan 1, 2029.
This market will resolve according to the first listed individual who publicly and unambiguously announces their candidacy in the 2028 United States presidential election, whether they are seeking any party nomination in the election or otherwise. An announcement that an individual is exploring a run or has formed an exploratory committee will be insufficient to resolve this market. The listed individuals are: Gavin Newsom, Alexandria Ocasio-Cortez, Jon Ossoff, Kamala Harris, Josh Shapiro, Pete Buttigieg, Jon Stewart, Andy Beshear, Rahm Emanuel, Ro Khanna, and Stephen A. Smith. An announcement by a listed individual will be sufficient to trigger resolution, regardless of whether they file their candidacy with the relevant regulatory authority. A campaign filing without an announcement will not be sufficient to resolve this market. If no listed individual makes such an announcement by December 31, 2027 at 11:59PM ET, this market will resolve to "Other". Once a qualifying announcement is made, subsequent withdrawal or retraction will not affect resolution. The primary resolution source for this market will be official statements by the listed individuals (ex: via speech, social media, etc.), however a consensus of credible reporting may also be used.
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
