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

Platform comparison

Market context

Once Upon A Team and ZennIT were scheduled for a best-of-three in the Road Of Legends regular season, but the live market shows the series as finished, with ZennIT taking the match 2-1 in the cited match listings. That matters because the market is already priced at 100% YES, so the current state reflects a settled outcome rather than a live sporting edge.

The main historical frame is that this pairing has tended to be competitive but not one-sided in every cycle. Recent head-to-head records across the supplied results show ZennIT with a modest edge overall, while the most recent completed meeting before this one was a 2-1 result for Once Upon A Team in May 2026, and broader archives show both teams have taken series off each other in Road Of Legends play.

For traders, the key catalysts are procedural rather than competitive: whether the event is officially marked complete, whether any scoreline reversal or voiding appears on the platform, and whether there is any dispute over the scheduled start time versus actual completion. Multiple listings now indicate the match has already been played, so the only practical risk is a settlement mismatch between the market venue and the match record rather than a later competitive change.

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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Prediction Today. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Today trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
