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.

Live prediction market odds for "How many Fed rate cuts in 2026?". 0 (0 bps) leads at 95.9%. Next is 1 (25 bps) at 1.4%. $65.5M has traded across 22 outcomes on Polymarket and Kalshi. The market is expected to resolve by Jan 1, 2027.
This market will resolve according to the exact amount of cuts of 25 basis points in 2026 by the Fed (including any cuts made during the December meeting). Emergency rate cuts outside of scheduled FOMC meetings will also count toward the total number of cuts in 2026. This market will remain open until December 31, 2026, 11:59 PM ET, to account for any such emergency actions. For example, if the Fed cuts rates by 50 bps after a meeting, it would be considered 2 cuts (of 25 bps each). This market will resolve early to "No" if the specified number of cuts becomes impossible — i.e., if more cuts have already occurred than the strike in question. Note that cuts between 1–24 bps (inclusive) will also be considered 1 rate cut. The resolution source for this market will be FOMC statements after meetings scheduled in 2026 according to the official calendar: https://www.federalreserve.gov/monetarypolicy/fomccalendars.htm. The level and change of the target federal funds rate is also published at the official website of the Federal Reserve at https://www.federalreserve.gov/monetarypolicy/openmarket.htm.
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%.
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.
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.
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.
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.
