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 "Next Token Sale on Coinbase by ___?". December 31, 2026 leads at 17%. Next is November 30, 2026 at 9.5%. $20K has traded across 3 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.
This market will resolve to "Yes" if a qualifying Coinbase token sale request window goes live between the creation of this market and the specified date at 11:59 PM ET. Otherwise, this market will resolve to "No". To qualify, a Coinbase token sale request window must be live and actively accepting commitments. Qualifying sales must be hosted directly by Coinbase on coinbase.com/token-sales or any official successor page within the Coinbase app or website. Sales run on a project's own site via Sonar, Echo, or any Coinbase-powered white-label technology do not qualify, regardless of affiliation. Private sales, airdrops, standard exchange listings, and any sale without a dedicated public request window do not qualify. Sale announcements, previews, and waitlists do not constitute a live request window. A request window that opens and is subsequently cancelled, paused, or suspended still resolves to "Yes" — post-opening outcomes including cancellation, refunds, pauses, or failure to distribute tokens do not affect resolution. If a sale is announced but the request window never opens, or a token is listed directly without a request window, this market resolves to "No". The resolution source is coinbase.com/token-sales, official Coinbase blog posts, or @Coinbase/@CoinbaseMarkets on X, corroborated by credible news sources.
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.
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.
