Only Polymarket lists this market, so there is no second price to compare.
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 3 min ago. Ages are as of when this page was built.

Live prediction market odds for "Will courts block Mamdani's grocery stores by...?". October 31 leads at 6.5%. $3K has traded across 1 outcome on Polymarket. The market is expected to resolve by Nov 1, 2026.
The Multicultural Business Coalition has filed a lawsuit against the City of New York seeking to block the opening of five municipally owned grocery stores planned under Mayor Zohran Mamdani's administration. This market will resolve to "Yes" if, between market creation and the specified date at 11:59 PM ET, a court issues any order — including a temporary restraining order, preliminary or permanent injunction, or other relief — that has the effect of prohibiting, suspending, or pausing the opening or operation of one or more of the planned municipal grocery stores. Otherwise, this market will resolve to "No". A qualifying order issued within the market timeframe will resolve this market "Yes" regardless of whether it is later vacated, reversed, stayed, or superseded, regardless of its stated duration, and regardless of whether any store would otherwise have opened during the market timeframe. A settlement, voluntary dismissal, or withdrawal of the litigation; a dismissal by the court; the City abandoning or modifying the grocery program in the absence of a qualifying court order; or any other disposition in which no qualifying order is issued will resolve this market "No". The primary resolution sources will be official court records and filings; 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.
