Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. 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.

Mostly the same bet: 4 differences

Where they differ

  • Kalshi settles on the party of the officeholder sworn in/inaugurated for the new term; Polymarket settles on the party of the called winner. They differ if the winner dies, withdraws or is not seated before the term starts.
  • Independents: Polymarket assigns a non-affiliated winner by stated caucus (House) or excludes independents from party options (Senate/Governor); Kalshi requires party membership.
  • Kalshi may close early on a media-consensus projection; Polymarket resolves on consensus calls with certification as the fallback.
  • Trading closes at different times: Nov 4, 2026, 4:59 AM UTC on Polymarket and Nov 3, 2027, 3:00 PM UTC on Kalshi.

About this market

Live prediction market odds for "NY-02 House Election Winner". Republican leads at 79.6%. Next is Democratic at 20.4%. $57K has traded across 2 outcomes on Kalshi and Polymarket. The market is expected to resolve by Nov 4, 2026.

This market will resolve according to the party of the candidate who wins the NY-02 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 parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources. This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).

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.
