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.

Prices come from our regular polls of each venue, the oldest 2 min ago. Ages are as of when this page was built.

About this market

Live prediction market odds for "Colorado Senate Election: Turnout". 2.7M-2.85M leads at 29.6%. Next is 2.55M-2.7M at 23.3%. $16K has traded across 8 outcomes on Polymarket. The market is expected to resolve by Nov 4, 2026.

This market will resolve according to the total number of valid votes cast in the 2026 midterm election for Senator from Colorado. If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. If the results of the specified election are not definitively known by March 31, 2027, 11:59 PM ET, this market will resolve to the lowest range bracket. All votes certified for candidates or non-candidate options in the specified election are included. Invalidated or blank votes are not included. In ranked-choice or preferential systems, the first-round vote total will be used. The primary resolution source for this market will be the official results of the 2026 midterm election for Senator from Colorado, as published by the state electoral authority responsible for certifying the results of the election; however, an overwhelming consensus of credible reporting may also be used.

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.
