Odds by venue

Consensus blends each venue’s last price, weighted by how much has traded there. 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. Ages are as of when this page was built.

About this market

Live prediction market odds for "How many Senators will vote for the Clarity Act?". Above 55 leads at 7.9%. Next is Above 64 at 7%. $327K has traded across 8 outcomes on Kalshi and Polymarket. The market is expected to resolve by Jan 2, 2027.

This market will resolve to "Yes" if the number of Senators voting "Yea" on the first Senate vote on final passage of crypto market structure legislation occurring before January 1, 2027 is above the number specified in this market's title. Otherwise, this market will resolve to "No". "Above" means strictly greater than the number specified in the title. For example, a market titled "Above 58" will resolve to "Yes" only if 59 or more Senators vote "Yea". For purposes of this market, "crypto market structure legislation" is defined identically to Polymarket's "Crypto Market Structure legislation becomes law in 2026?" market: https://polymarket.com/event/crypto-market-structure-legislation-becomes-law-in-2026-20260727223933088 The qualifying vote must be a vote on final passage of the bill conducted in the full Senate - not a committee vote, and not a vote on a motion to proceed, a motion to invoke cloture, or an amendment. Not every Senator needs to have participated in the vote. The first vote on final passage will be used for resolution regardless of whether the bill passes on that vote; subsequent votes on passage — including any re-vote following a motion to reconsider, or a vote on a conference report or House-amended version — will not be considered. If no qualifying vote occurs before January 1, 2027, this market will resolve to "No". If qualifying legislation passes the Senate before January 1, 2027 without a prior recorded vote on final passage (e.g., passage by voice vote or unanimous consent), this market will resolve to "Yes" regardless of the number specified in this market's title. Once the result of the vote has been announced, any subsequent request by a Senator to add, remove, or change a vote will not be considered for purposes of this market, regardless of any change to the official vote tally. This market will resolve according to official records of the U.S. Senate (http://senate.gov) and Library of Congress (http://congress.gov).

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.
