Next is kt Rolster at 96.6%. 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. Ages are as of when this page was built.

Live prediction market odds for "Which Teams Will Make a Roster Change Before December?". NONGSHIM RED FORCE leads at 98%. Next is kt Rolster at 96.6%. $31K has traded across 40 outcomes on Polymarket. The market is expected to resolve by Dec 1, 2026.
This market will resolve to "Yes" if any player joins or leaves the listed team's active League of Legends roster (defined as the active lineup listed on the listed team's Liquipedia page) by November 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". The relevant roster is whichever active lineup is listed on the resolution source at market creation. Name changes or aliases referring to the same player do not qualify as roster changes. For the purpose of this market, "roster change" refers to any official signing, transfer, benching to inactive/reserve, release, retirement, or departure of a player from the active lineup. This includes adding new players (transfers, free agent signings, or loans), removing players (to inactive, free agency, or other teams), or any change resulting in a different active roster. A qualifying roster change must occur on or before the deadline, and be reflected in the resolution source. Once the change appears in the resolution source, it must remain live for at least 48 continuous hours to be valid. This 48-hour period may finish after the deadline, so long as the change itself occurred on or before the deadline. If the change is reverted or removed before 48 hours have elapsed, the window resets and will not count toward resolution. Coach changes and temporary stand-ins for a single match will not count. The primary resolution source for this market will be Liquipedia; 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.
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.
