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.

About this market

Live prediction market odds for "Will any US Federal or Statewide Midterm Election be within 0.01%?". Yes leads at 21.5%. $1K has traded across 1 outcome on Polymarket. The market is expected to resolve by Nov 3, 2026.

The 2026 midterm elections are scheduled to be held on November 3, 2026. This market will resolve to "Yes" if any federal or statewide election held on November 3 has a margin of victory of 0.01% or less. Otherwise, this market will resolve to "No". For the purpose of this market, the “margin of victory” is defined as the absolute difference between the percentages of valid votes received by the first- and second-place candidates. Percentages of the valid votes received by each candidate or option will be determined by dividing the total number of valid votes each of the top two candidates receives by the sum of all valid votes cast in the election. In the midterms, a federal election is an election to either the United States Senate or House of Representatives (including non-voting seats), and a statewide election is any election, excluding ballot measures, which is on the ballot for all voting individuals within one of the fifty United States. For elections decided through ranked-choice voting or another multi-round tabulation of ballots cast in a single election, the relevant margin will be the margin between the final two candidates in the tabulation round in which the winner is determined, calculated using the valid votes remaining active in that round. If a separate runoff or subsequent round is held on another date, only the results of the November 3 election will be considered, regardless of whether that election determines the eventual winner. The resolution source for this market will be the certified results of the United States state and territorial election authorities, however, a consensus of credible reporting may also be used. If the results of any election cannot be determined by March 31, 2027, it will not be included for purposes of this market.

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.
