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. Ages are as of when this page was built.

Live prediction market odds for "Will Iran damage undersea internet cables by...?". December 31 leads at 20.5%. Next is October 31 at 4.8%. $51K has traded across 2 outcomes on Polymarket. The market is expected to resolve by Nov 1, 2026.
This market will resolve to "Yes" if Iran or an Iranian proxy group physically damages undersea internet cables between market creation and the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”. For the purposes of this market, Iranian proxy groups are: any organization directly controlled by Iran, Hezbollah, Hamas, Palestinian Islamic Jihad, Houthis ("Ansar Allah"), Kata'ib Hezbollah, Asa'ib Ahl al-Haq, Badr Organization, and Harakat al-Nujaba. Only physical damage to undersea internet cable infrastructure will be considered. Cyber attacks will not qualify, even if they have kinetic effects. A qualifying incident must be deliberately caused by, or result from an attack or other deliberate action by, Iran or an Iranian proxy. Damage caused as a result of an Iranian or Iranian proxy attack on a vessel will qualify. Attempted attacks that do not result in damage will not qualify for a "Yes" resolution. The occurrence, cause, and attribution of qualifying cable damage will be primarily determined based on a consensus of information available from the resolution sources. Where multiple sources conflict regarding the occurrence, cause, or attribution of relevant cable damage, this market will remain open until the earlier of: i) the confirmation of the occurrence, cause, and attribution of the damage based on a consensus of information available from the resolution sources or ii) 3 full calendar days (ET) from the date of the first credibly reported evidence of the damage. If this period would extend past the end date, this market will remain open to allow for 3 full calendar days to pass. If, at the end of the third calendar day, conflicting reports remain as to the occurrence, cause, or attribution of the damage, the incident will be adjudicated based on the totality of information available from the resolution sources at that time. No single statement, denial, or presentation of evidence will govern where it is contradicted by the totality of information. The resolution source for this market will be credible reporting.
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.
