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 1 min ago. Ages are as of when this page was built.

About this market

Live prediction market odds for "Any member-elect blocked from being sworn in on Jan 3, 2027?". Yes leads at 8.5%. $4K has traded across 1 outcome on Polymarket. The market is expected to resolve by Jan 4, 2027.

The 120th United States Congress is scheduled to convene on January 3, 2027. On each chamber's opening day, the members-elect of the House of Representatives and the newly elected members of the Senate are expected to take the oath of office. This market will resolve to "Yes" if, on the day a chamber swears in its members-elect, any member-elect of that chamber is not sworn in because the oath is withheld from them. Otherwise, this market will resolve to "No". The oath is withheld from a member-elect if they are not sworn in on that day for any reason other than their own absence or choice, including, but not limited to: - an objection to, or challenge of, their election or credentials, including being asked to stand aside while the other members-elect take the oath; - a vote or decision by the chamber not to seat them; - the referral of their credentials or right to the seat to a committee; or - a decision by the presiding officer or the Clerk of the House not to administer the oath to them. The following will not qualify for a "Yes" resolution: - A member-elect who is absent, ill, or otherwise does not appear to take the oath on that day. - A member-elect who resigns, declines to take their seat, or otherwise ceases to be a member-elect before the oath is administered. - A seat for which no winner has been certified by the appropriate state authority by the time the chamber convenes (e.g. a close race that is still being counted or recounted). A "member-elect" is any individual certified by the appropriate state authority, as of the day the relevant chamber convenes, as the winner of an election to the U.S. House of Representatives or the U.S. Senate for a term beginning on January 3, 2027, including the winner of any special election certified by that time. Delegates and the Resident Commissioner are not included. A member-elect is sworn in when the oath of office is administered to them on the floor of their chamber on that day, whether together with other members-elect or individually. The relevant day for each chamber is: - Senate: the day the Senate first convenes in the 120th Congress and swears in newly elected Senators. - House: the day the House administers the oath of office to its members-elect, which happens after a Speaker is elected. If the House has not elected a Speaker on January 3, 2027, the relevant day is the day the oath is administered after the Speaker is elected. If the 120th Congress convenes on a date other than January 3, 2027, the relevant day for each chamber is the day it first swears in its members-elect. Each chamber is assessed separately; if a chamber has not sworn in its members-elect by January 31, 2027, 11:59 PM ET, no qualifying event will be considered to have occurred in that chamber. The primary resolution source for this market will be official information from the United States House of Representatives and the United States Senate, including the Congressional Record, the Clerk of the House, and the Secretary of the Senate; however, a consensus of credible reporting will 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.
