Market context

Yakult Brothers face Game Master in the upper bracket quarterfinals of The International China Closed Qualifier on 15 June at 06:00 ET, with the winner advancing deeper into the regional playoff structure. Polymarket currently prices this contract at 100% YES for Yakult Brothers, reflecting either exceptionally strong conviction amongst traders or insufficient liquidity to establish a meaningful spread. The settlement window closes at 15:00 ET the same day, allowing a nine-hour window for the match to conclude before conditional token resolution occurs on Polygon.

Chinese Dota 2 qualifiers have historically produced volatile results when favourites face unfamiliar opposition, particularly in upper bracket knockout formats where single-elimination pressure amplifies upsets. Game Master's recent tournament placements and head-to-head record against Yakult Brothers should inform whether the 100% probability reflects genuine dominance or simply thin order books. Previous International qualifiers from the region have seen teams ranked outside top-three seeding eliminate higher-ranked squads, though Yakult Brothers' consistency in recent months may justify the market's confidence.

Traders should monitor official ESL or PGL announcements regarding match scheduling, as delays beyond seven days trigger a 50-50 resolution. Team roster confirmations and any last-minute stand-in announcements would shift the underlying matchup dynamics. Broadcast schedules from the official Dota 2 channels should be verified against the 06:00 ET start time, as scheduling discrepancies between regions occasionally occur. The absence of meaningful counter-positions on Polymarket suggests limited arbitrage opportunities unless fresh information emerges before kickoff.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
