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

Platform comparison

Market context

Polymarket is pricing **Once Upon A Team vs ZennIT** at **100% YES** on the contract, which is effectively a maxed-out view that Once Upon A Team will be the eventual winner and the market will settle accordingly on Polygon in USDC via conditional tokens. In practical terms, that leaves very little room for new information to move the price unless there is a late schedule change, a walkover, or a result source issue under the market rules.[17]

The current read is best understood against prior meetings, where ZennIT has generally had the edge. Historical match pages and head-to-head trackers show ZennIT leading the overall series 3-2 in one archive, while other summaries across a broader sample put ZennIT ahead 5-1 or 5-3 depending on which fixtures are counted, which is a reminder that these pages do not always capture the same scope of games.[4][8][11][16] That makes a 100% implied probability look aggressive relative to the longer-run record, especially in a BO3 format where one dropped game can quickly expose volatility.[1][4]

For traders, the main catalysts are not abstract team strength but match administration: whether the fixture is confirmed, starts on time, and is fully completed before the 7-day delay rule kicks in. The contract resolves from official information on gol.gg, with credible reporting only acting as a back-up if final results are not posted within two hours after conclusion, so any delay in publishing the series score can matter at the margin.[17] A late roster change, a postponement, or an incomplete series decided by forfeit would all be more relevant to settlement than pre-match opinion, and the Polymarket event page already shows the same fixture appearing across the platform’s team and match listings.[14][17]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
