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

Platform comparison

Market context

Once Upon A Team’s meeting with ZennIT in Road Of Legends was originally scheduled as a best-of-three regular-season series, but the market now carries a 100% yes price even though the underlying match result on the available score pages is inconsistent across tracking sites. BO3.gg shows the teams’ most recent May 2026 series ended 2–1 to Once Upon A Team, while another match tracker records a 2026 Road Of Legends series won 2–1 by ZennIT on the August date referenced by the market.[1][3]

For historical framing, ZennIT has generally had the stronger head-to-head record across recent seasons. Third-party archives show ZennIT leading the matchup overall, with several sources crediting it with more series wins than Once Upon A Team and a broader map edge, although the exact totals vary by database and date range.[6][10][11] That kind of profile helps explain why a perfect 100% implied probability looks aggressive unless the market has already fully incorporated a confirmed official result.

The main catalysts to watch are official match status updates, roster confirmations and any schedule changes that could push the series beyond the settlement window. Prior match pages indicate both teams have had uneven recent form, including streaky results and at least one recent stand-in for Once Upon A Team, so late team-sheet news matters if this were still unresolved.[4][7][11] If the organiser, team social accounts or a live-results partner confirm the fixture was played to completion, that will matter more than pre-match ratings; if not, the market’s outcome may depend on whether the event was cancelled, delayed or treated as a no-contest under the rules.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
