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

Platform comparison

Market context

The Bandits and ZennIT are scheduled to play a best-of-three in the Road Of Legends regular season, and the contract only pays out on a completed result, a cancellation, or a significant delay. With the crowd at 100% YES, Polymarket-style pricing is effectively reading this as a near-certainty that The Bandits will be credited as the winner rather than a genuine two-sided game price; on Kalshi, the same event would typically be shown as a straight yes/no probability, while Betfair and Smarkets would express the same view through decimal odds and exchange prices instead of a binary contract.

For comparison, very short-dated esports markets often look “locked” once lineups, server checks, and broadcast schedules are confirmed, because the remaining uncertainty is less about who is stronger and more about whether the match starts on time and finishes cleanly. That matters here because a 100% reading can still conceal settlement risk if the fixture is postponed, abandoned, or resolved by forfeit, which would push the market towards a 50-50 outcome under the contract rules. In exchange-book terms, Betfair and Smarkets also differ from Polymarket and Kalshi because their pricing includes market-driven overround/commission mechanics rather than a directly stated contract probability, and access is constrained by local KYC and regulatory reach.

The main catalysts are operational rather than competitive: any official announcement from the organiser about server availability, start-time changes, or a reschedule would be the key trigger for repricing. Traders would also watch for lineup confirmations and whether the series actually begins, because once play starts the settlement path changes materially if one side concedes or cannot complete the BO3. On a platform-comparison basis, this is the kind of market where the headline probability on Polymarket or Kalshi can look identical, but the practical value depends on fee drag, whether the venue accepts your jurisdiction, and how each venue handles late information on postponements and non-completions.
