Market context
Yellow Submarine’s Group A meeting with Execration is listed to start at 05:00 UTC on 31 July, in a best-of-three at Games of the Future. At this settlement window, the market is effectively pricing a completed Yellow Submarine win, but the on-chain resolution still depends on the official result being recorded before the deadline, not on crowd sentiment alone.[1][17][15]
The current **100% YES** reading is best compared with other near-certain esports contracts that trade at the ceiling when the match is live, already finished, or the reporting lag is narrow. In this fixture, external scoreboards are already inconsistent on timing and status, with some listings showing the game as live or finished and others still marking it upcoming or postponed, which is exactly the sort of discrepancy that can matter for USDC-settled markets if the oracle follows the formal match feed rather than a community tracker.[5][6][7][8][13]
What matters now is whether the organiser confirms the series has been played to completion and which side is declared the winner, because any cancellation, walkover ambiguity, or delay beyond seven days would force a 50-50 resolution under the contract terms. Traders should also watch for late schedule changes from the tournament bracket and any live score updates, since the event page and third-party esports listings may lag one another; by contrast, the contract payoff in USDC will only reflect the final verified outcome, not the path the market took to get there.[1][15][17]
Methodology
Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.
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
- 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.
- How volatile are crypto prediction markets?
- Crypto markets react to spot prices — a 5% BTC move typically shifts a "BTC above X by date" market 10-20%. Polymarket crypto market liquidity is usually six-figure USD, sufficient for active trading.
- 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.
