Odds by venue

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 "Nebraska Senate Election Winner ". Republican leads at 75.1%. Next is Independent at 26.5%. $4.0M has traded across 4 outcomes on Kalshi and Polymarket. The market is expected to resolve by Nov 4, 2026.

This market will resolve according to the winner of the 2026 midterm Nebraska U.S. Senate election, inclusive of any run-offs. A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date. Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party. The candidates may be named in the contract for the convenience of traders. In the event that any named candidate is replaced as the nominee of their respective party prior to election day, the name in the contract will be updated and the market will resolve based on the replacement nominee of the party. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources call the race for the same candidate. If all three sources haven’t called the race in this state for the same candidate, this market will resolve based on the official certification.

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.
