LoL: DN SOOPers vs BNK FEARX (BO1) - KeSPA Cup Group Stage

Platform comparison

Market context

DN SOOPers face BNK FEARX in a single-game elimination match for the KeSPA Cup Group Stage, scheduled to begin at 2:45AM ET on 20 July. The crowd-implied probability sits at 100% YES for DN SOOPers winning, a figure that demands scrutiny given the inherent volatility of League of Legends BO1 formats where a single lapse can overturn expectations.

Historically, 100% implied probabilities in esports prediction markets rarely reflect absolute certainty but instead signal severe liquidity imbalances or a lack of competing data points. Comparable cases from the LCK 2026 season show that even heavily favoured teams in BO1 matches have suffered unexpected losses due to patch-specific meta shifts or roster instability, making such extremes a potential arbitrage signal for programmatic traders rather than a guaranteed outcome. Automated strategies often flag these anomalies to execute conditional orders that hedge against the 50-50 resolution clause triggered by cancellations or forfeitures.

Traders must monitor the official KeSPA Cup schedule for any last-minute delays beyond the seven-day settlement window, as well as real-time stream health on Twitch and YouTube where the match is broadcast live. Recent coverage on Strafe Esports confirms the match is listed as live, but any announcement regarding team disqualifications or server failures could instantly invalidate the current pricing. Programmatic approaches should integrate webhook listeners for these dependencies to adjust exposure before the settlement window closes at 13:10 UTC on 20 July.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Kalshi Fees, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

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 Kalshi Fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.
