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 Elon Musk tweet "Hyperliquid" by ___?". December 31, 2026 leads at 11.5%. Next is November 30, 2026 at 8.5%. $67K has traded across 3 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.
This market will resolve to "Yes" if https://x.com/elonmusk posts the listed term by 11:59 PM ET on the date specified in the title. Otherwise, this market will resolve to "No". For the purposes of this market, all text posted by the listed account in main feed posts, quote posts, and reply posts count toward a "Yes" resolution, but quoted posts and reposts will not count. Text posted in images, memes, or other non-animated, non-video media that are not strictly text will qualify towards a "Yes" resolution only if the listed term is spelled out clearly and in full. (e.g., words spelled out in a letter posted as a .jpg will qualify, however a word posted as part of an animated .gif will not.) Any plural or possessive forms of the listed term, as well as variance in capitalizations, will count toward the resolution of this market, regardless of context. Other forms of the listed term will NOT count. Extraneous symbols being inserted into a word (ex: H@perl1quid, for "Hyperliquid") will disqualify it from counting toward a "Yes" resolution. Sigils at the beginnings of words, such as hashtags, "@" symbols, or denotations of currency, will not disqualify a term from counting towards a "Yes" resolution. Misspellings or iterations of the listed term, including all grammatical or slang forms, or misspellings with extra, missing, or incorrect letters (ex: Hyperliquidd or Hyperliqid, for "Hyperliquid"), will not count toward a "Yes" resolution, regardless of context or intent. Instances where the listed term is used in a compound word will count regardless of context (e.g. joyful is not a compound word for "joy," however "killjoy" is a compounding of the words "kill" and "joy"). Posts published from https://x.com/elonmusk during a period in which the account is verifiably compromised or hacked, as confirmed by Elon Musk or X, do not qualify. The resolution source for this market will be Elon Musk's verified X account: https://x.com/elonmusk Please note, only the https://x.com/elonmusk verified X account counts for this market. If Elon Musk posts from another account, it has no bearing on the resolution of this market.
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.
