LoL: The Bandits vs ZennIT (BO3) - Road Of Legends Regular Season

Platform comparison

Market context

The market is about a best-of-three *League of Legends* match between The Bandits and ZennIT in the Road Of Legends regular season, with settlement tied to the actual result rather than the map score. A 100% crowd-implied probability usually means the contract is pricing in either a completed result already or very strong certainty that the listed outcome will stand, which is more informative than a simple “favourite” read on an exchange like Betfair or Smarkets, where traders would normally see decimal odds and then convert them into an implied probability. On Polymarket and Kalshi, the same event would be framed in probability terms, but the practical difference is that Kalshi’s KYC is tighter and its market access is more geographically limited, while Betfair and Smarkets present the same underlying uncertainty through odds and liquidity rather than a binary yes/no price.

For comparison, markets like this often stay pinned when the scheduled fixture is either completed or expected to resolve cleanly before the deadline; they only tend to reprice sharply if there is evidence of postponement, cancellation or a forfeit. In a BO3, the main distinction is that a match that starts but is not completed can still settle by the official winner if one side concedes, whereas a no-contest or a delay beyond seven days would push settlement to 50-50 under the contract rules. On an exchange platform, that resolution risk is usually reflected in the spread and commission, whereas on a prediction market the headline probability already embeds the crowd’s view of whether the match will actually be officially adjudicated.
