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

Platform comparison

Market context

Once Upon A Team meet ZennIT in a Road of Legends regular-season best-of-three, with the market already pricing a full **100% YES** outcome for Once Upon A Team. That level is consistent with the contract’s binary resolution logic: if the series is played to a normal finish, the winner settles the market; if it is not played, is tied, or slips beyond the seven-day window without a winner, it reverts to 50-50 rather than paying out cleanly.

The historical frame is mixed rather than one-sided. Once Upon A Team beat ZennIT 2–1 in May 2026, but broader head-to-head data still favours ZennIT, who have won more of the recent meetings overall and were rated higher in several third-party listings. Strafe’s current team pages also show ZennIT better placed in its rankings, while Polymarket’s own team page has the market much nearer balance at 56% to 44%, which makes the live 100% crowd view stand out as aggressive relative to the underlying match history.[1][6][10][11]

The main catalysts are operational rather than macro: confirmation that the series starts on schedule, whether the scheduled BO3 is preserved after any lobby or broadcast changes, and whether there are any roster or format announcements before pick-bans. For prediction-market traders, the practical on-chain angle is that settlement is in USDC and the key risk is not just who wins but whether the match is completed in a way that the market rules recognise; if the event is disrupted, the payoff path can change sharply. BTC and ETH moves matter only indirectly here, through broader risk appetite and USDC liquidity, so the contract is still driven primarily by esports scheduling and results rather than crypto beta.

Methodology

This page reads LoL: Once Upon A Team vs ZennIT (BO3) - Road Of Legends Regular Season on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

How does UMA secure the resolution?

The UMA Optimistic Oracle uses a bond system: a proposer posts a bond, a two-hour challenge window opens. On dispute the losing side forfeits the bond — financial incentive for honest resolution.

Which crypto markets exist on Polymarket?

Currently active markets include BTC/ETH/SOL price targets, halving dates, ETF approvals, hard-fork outcomes and Layer-2 TVL thresholds. The list updates weekly; biggest volume sits on BTC and ETH price forecasts.
