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 176 days ago. Ages are as of when this page was built.

Final prediction market prices for "Will SOFR hit __ in April?". 3.74% last traded at 50%. Next is 3.76% at 50%. $21K has traded across 2 outcomes on Polymarket. The market closed on Apr 30, 2026.
The Secured Overnight Financing Rate (SOFR) is a measure of the cost of borrowing cash overnight, collateralized by US Treasury securities. SOFR is used to price loans, bonds, derivatives, and more. The SOFR rate is published by the Federal Reserve Bank of New York each business day at 8:00 AM ET, for the previous business day. This market will resolve to “Yes” if the Federal Reserve Bank of New York publishes a daily SOFR rate (%) equal to or above the listed value for any business day between April 1 and April 30, 2026. Otherwise, this market will resolve to “No”. This market will resolve as soon as the SOFR rate is equal to or above the listed value during the specified period, or when SOFR data is published for the final business day on or before April 30, 2026. If no data is published for the final business day on or before April 30, 2026 by May 07, 2026, 11:59 PM ET, this market will resolve based on the data published up to that point. Business day refers to any day treated as such by the Federal Reserve Bank of New York. Any revisions to the daily SOFR values published by the Federal Reserve Bank of New York prior to the release of SOFR data for the final business day on or before April 30, 2026 will be considered; however, these revisions will not disqualify a previously published SOFR rate from counting. Any revisions published after the release of SOFR data for the final business day on or before April 30, 2026 will not be considered. The primary resolution source for this market will be the Federal Reserve Bank of New York, specifically the Secured Overnight Financing Rate Data table at https://www.newyorkfed.org/markets/reference-rates/sofr. Note: This market’s resolution source publishes the SOFR rate to two decimal places (e.g. 3.65%). Thus, this is the level of precision that will be used when resolving this market.
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.
