Live prediction market odds for "Miles Morales live-action film actor?". No actor chosen by end of 2027 leads at 82.5%. Next is Caleb McLaughlin at 14.4%. $25K has traded across 8 outcomes on Polymarket and Kalshi. The market is expected to resolve by Jan 1, 2028.
This market will resolve based on the first official announcement of who will play Miles Morales in a live-action feature film by December 31, 2027, 11:59 PM ET. Actors announced to play the character in animated films or TV series will not qualify. Only live-action feature film castings will qualify. If more than one actor is announced to portray Miles Morales in the same film, only the actor cast in the principal role of the character will qualify. Actors cast to portray a younger, older, alternate, or variant version of the character, and actors serving as body doubles, stunt doubles, or voice doubles, will not qualify. If no actor is announced as the live-action Miles Morales within the timeframe, this market will resolve to "No actor chosen by end of 2027". The primary resolution source for this market will be official information from Sony Pictures, Marvel, their parent companies, or another authorized representative of the Spider-Man franchise. 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.
