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

Platform comparison

Market context

The Bandits are scheduled to face ZennIT in a best-of-three Road Of Legends Regular Season match, and the market is effectively pricing the outcome as a done deal with a **100% YES** crowd-implied probability. In practical terms, that reflects either very strong confidence in The Bandits or a stale price that has not yet adjusted to current conditions; on Polymarket, that translates into a binary share price near the maximum, whereas on Kalshi the same view would be expressed as a near-100 contract price and on Betfair or Smarkets as ultra-short decimal odds with fees making the realised return even slimmer.

For traders comparing books, the key point is that these venues do not present the same number in the same way. Polymarket shows implied probability directly, while exchange-style books quote decimal odds and then take commission, so a market that looks like 1.01 or 1.02 can still be meaningfully different after fees. KYC access also matters: Kalshi is more tightly gated than a crypto-native venue, while Betfair and Smarkets generally require standard exchange verification and may restrict access by jurisdiction, which affects who can trade this match and how quickly liquidity can move if a line is challenged.

The main catalysts are straightforward: confirmation that the match is actually played on schedule, any official delay beyond the settlement window, and any bracket or administrative change that affects whether a result is recorded at all. Because this market resolves to 50-50 if the match is cancelled, tied, or pushed more than seven days without a winner, traders should watch tournament announcements and team communications for postponements, walkovers, or forfeits; if the series starts but does not finish, the settlement still depends on which side is awarded the win, so mid-series disruption is not neutral.
