Market context

The International China Closed Qualifier Playoffs determine which Chinese Dota 2 teams advance to The International, the annual world championship. Yakult Brothers face Game Master in an upper bracket quarterfinal best-of-three match scheduled for 15 June at 06:00 ET. The current crowd-implied probability of 100% YES suggests near-certainty that the match will occur and produce a winner, though the settlement window closes at 15:00 ET the same day—a tight six-hour window that leaves minimal margin for fixture delays or technical complications.

Chinese regional Dota 2 qualifiers have historically proceeded on schedule, with cancellations or extended delays rare outside major infrastructure failures or player visa complications. Both teams compete regularly in the Chinese domestic circuit, reducing the likelihood of roster unavailability. However, esports fixtures occasionally slip by two to four hours due to broadcast scheduling conflicts or preceding matches running long. The 100% probability reflects confidence in match completion rather than a specific outcome prediction; traders should note that any delay pushing resolution beyond 22 June would trigger the 50-50 tie resolution clause.

Key catalysts include official fixture confirmations from PGL or the Chinese Dota 2 Pro Circuit organisers, typically published 48 hours before play. Recent Chinese qualifier events (May–June 2026) have maintained published schedules without major postponements. Monitor team announcements for player illness or equipment issues in the 72 hours before match time. USDC settlement will execute upon confirmed match result, with on-chain confirmation typically occurring within two hours of official broadcast conclusion.

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 — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.

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

Where can I trade this market with the lowest fees?

On BTC Prediction, which mirrors the Polymarket order book at 0% 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 it cost to trade on BTC Prediction?

Zero. BTC Prediction routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

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.
