LoL: Once Upon A Team vs ZennIT (BO3) - Road Of Legends Regular Season

Platform comparison

Market context

Polymarket currently prices this BO3 as a near-certain **Once Upon A Team** win, with the contract sitting at **100% YES** on-chain in USDC on Polygon through the market’s conditional-token structure. In practical terms, that means traders are already treating the settlement as overwhelmingly likely to resolve to OUAT rather than ZennIT, even though the market still follows the event outcome rather than the pre-match spread or map count.

That kind of pricing is best read against the teams’ recent head-to-head history, which is mixed rather than one-sided. Public match records show the sides have played multiple times across 2024–2026, with ZennIT holding the longer-term edge overall, but Once Upon A Team winning their most recent meeting on 14 May 2026 by 2–1 in Road of Legends play[1][6][9][16]. Polymarket’s own team page has also shown OUAT ahead in the related match markets, suggesting the current contract is not trading on a vacuum but on expectations shaped by recent results and matchup memory[15].

For a trader, the key catalysts are straightforward: whether the fixture is actually staged on the scheduled date, whether there is a late reschedule, and whether the series starts and completes normally under the market’s settlement rules. If the game is cancelled, drawn, or delayed beyond seven days without a winner, the contract resolves 50-50; if it starts but does not finish, the final official result still matters for settlement. Any live broadcast confirmation, bracket update, or league admin announcement around the Road of Legends schedule can therefore matter more than the pre-event price itself.
