About this market

What resolves this contract

This market will resolve according to the party of the candidate who wins the PA-13 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 3, 2026. ​A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these p

Reading the odds on this market

At 96.4¢ for YES, traders are pricing about a 96.4% chance this happens, roughly 26.8 to 1 in favour.

$10 on YES buys about 10 contracts that pay $10.37 if it happens; $10 on NO at 3.6¢ buys about 277.8 that pay $277.78 if it does not.

The favoured side, YES, returns 3.7% if it wins, with the money locked up for 40 days until November 5, 2026; that works out to about 39.7% a year.

Over the last 31 daily readings the YES price barely moved, trading between 96.4¢ and 97.9¢.

$9,916 has traded on it on Polymarket, with $8,462 still riding on the outcome, making it number 75 by volume of the 215 markets we track.

Payouts are before platform fees; one contract pays $1 if its side wins.

How to read the price

Prediction market prices are expressed in cents on the dollar. A YES contract trading at 96¢ means the market is pricing in a 96.4% implied probability of the event resolving YES. If resolution comes back YES, the contract pays $1. If NO, it pays $0.

Volume vs. open interest

Total traded volume ($9,916) reflects every buy and sell across the life of this contract. Open interest ($8,462) is the dollar value of positions currently held by traders. Deep liquidity and wide open interest are the two signals that the quoted price is reliable.
