About this market
Final prediction market prices for "Will OpenSea launch a token by the end of 2021?". $148K has traded across 0 outcomes on Polymarket. The market closed on Dec 31, 2021.
This is a market on if OpenSea will have a live token by December 31, 2021, 11:59:59 PM ET. Having a live token in this context can be defined as a deployed-to-mainnet, actively transferrable and/or tradable token that is in some way native to the application, and substantiated by the respective project via website or social media channels. Empirically speaking, having a live token will be considered fulfilled if official project channels announce the introduction of the token and it is live on mainnet, and swappable and acquirable (i.e. via Uniswap). In the case of a token being announced but not yet transferrable or “live”, that will not satisfy market conditions. If the token is deployed to mainnet (in any form, including some sort of voucher), but is not transferrable, that will also not satisfy market conditions. In the case of ERC20 tokens, if the token is deployed, but there is no existing Uniswap pool for the token, it will be considered not “live” and thus will not satisfy market conditions. For clarity, this market is about fungible tokens, and not NFTs related to a platform. If OpenSea has a live token by December 31, 11:59:59 PM ET, this market will resolve to "Yes". If the resolution date is reached and none of the projects have a token, the market will resolve to "No". In the case of ambiguity, the market will be resolved in good faith by the Markets Integrity Committee (MIC).
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.
