Next is Kamala Harris at 27.5%. The venues list this event, but none of their outcomes are matched yet, so prices are shown separately.

Odds by venue

Consensus blends each venue’s last price, weighted by how much has traded there. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.

Prices come from our regular polls of each venue, the oldest 6 min ago. Ages are as of when this page was built.

About this market

Live prediction market odds for "South Carolina Presidential Democratic Primary Winner". Yes leads at 94%. Next is Kamala Harris at 27.5%. $28K has traded across 21 outcomes on Polymarket and Kalshi. The market is expected to resolve by Jan 23, 2028.

South Carolina is expected to hold its Democratic presidential primary for the 2028 presidential election on January 22, 2028. This market will resolve to the candidate who wins the most votes in the South Carolina Democratic primary, caucus, or other official process by which the public directs the selection of delegates for the 2028 Democratic Convention. If the relevant delegate selection process is a caucus or other multi-round process, the relevant vote count will be the final round vote count. The named candidates will be primarily ranked by the number of valid votes received in the specified election. If two or more candidates are tied on valid votes, ties will be broken by alphabetical order of the candidates' last names. This market will resolve to the candidate that occupies the highest finishing position after applying this ranking. If no 2028 South Carolina primary, caucus, or comparable process takes place, or if the results are not definitively known by August 1, 2028, 11:59 PM ET, this market will resolve to “Other.” The resolution source for this market will be the first official announcement of the complete results from the South Carolina Democratic Party; however, an overwhelming consensus of credible reporting may suffice.

Questions

What does the consensus price mean?

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%.

How is the payout worked out?

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.

Why do the venues show different prices?

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.

Is a price gap an arbitrage?

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.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
