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

Live prediction market odds for "Will any country join the Mecca Agreement by...?". December 31 leads at 24.5%. Next is October 31 at 2.1%. $66K has traded across 2 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.
The Makkah Joint Defence Agreement (also known as the Makkah Accord or Mecca Joint Defense Agreement) is a collective-defense agreement signed by Saudi Arabia, Türkiye, and Pakistan on August 7, 2026, under which an armed attack against any one of the three countries is regarded as an attack against them all. The agreement has subsequently been described by its signatories as open to additional countries. This market will resolve to “Yes” if any country other than Saudi Arabia, Türkiye, or Pakistan formally joins the Makkah Joint Defence Agreement by the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”. A country will be considered to have formally joined if either of the following occurs: the country signs the Agreement or a formal accession protocol or instrument that, by its terms or official characterization, makes it a party, member, or signatory; or the country and the Agreement’s existing parties officially announce, jointly or separately, that the country has become a party, member, or signatory. Statements of intent, applications, invitations to join, negotiations, parliamentary authorization, approval in principle, or general defense cooperation will not qualify. A separate bilateral or multilateral defense agreement will not qualify unless it is officially identified as accession to the Makkah Joint Defence Agreement. Once a qualifying accession has occurred, this market will resolve to “Yes,” regardless of any subsequent withdrawal, suspension, reversal, or termination. The primary resolution sources for this market will be official information from the governments of Saudi Arabia, Türkiye, Pakistan, and any country reported to have joined; however, a 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.
