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, the oldest 4 min ago. Ages are as of when this page was built.

Live prediction market odds for "US Treasury announces Bitcoin purchase by ___?". December 31, 2027 leads at 20%. Next is December 31, 2026 at 3.2%. $4K has traded across 2 outcomes on Polymarket. The market is expected to resolve by Jan 1, 2027.
This market will resolve to "Yes" if the US Department of the Treasury officially announces that it has purchased Bitcoin between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". The announcement must clearly and unambiguously communicate a completed purchase of Bitcoin; statements that the Treasury intends, plans, or is authorized to purchase Bitcoin, including through legislation or an executive order, will not qualify. Bitcoin acquired through seizure, forfeiture, or other non-purchase means, and indirect exposure such as funds or ETFs, will not qualify. An announcement will suffice for a "Yes" resolution, regardless of whether the announcement is later reversed or retracted, or whether the Bitcoin is subsequently sold. A qualifying announcement must come from an official U.S. government source or an authorized U.S. government official acting in an official capacity, and must concern a purchase carried out by or on behalf of the Treasury. Qualifying sources include Treasury press releases, statements, websites, social media accounts, and Federal Register notices, as well as recorded or written statements by Treasury officials, the President, or the White House. For purposes of this market, the Treasury includes its bureaus and sub-bodies, such as the Bureau of the Fiscal Service, and any Treasury-authorized entity acting on its behalf. The primary resolution source will be official information from the United States government; however, a definitive consensus of credible reporting may also be used.
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.
