Market context

Yakult Brothers face Game Master in an upper bracket quarterfinal of the International China Closed Qualifier Playoffs, a Dota 2 tournament serving as the primary pathway for Chinese teams to secure spots at The International. The match is scheduled for 15 June at 06:00 ET, with settlement contingent on a decisive result within seven days. Polymarket currently prices this contract at 100% YES, implying near-certain confidence that the match will be played and produce a winner rather than cancellation, tie, or extended delay.

Chinese Dota 2 qualifiers have historically maintained reliable scheduling and completion rates, though regional tournaments occasionally experience technical delays or roster complications that push matches beyond their original windows. The 2024 International qualifier cycle saw most upper bracket fixtures resolve on schedule, with cancellations remaining rare. The 100% probability reflects both the structural stability of the closed qualifier format and the high stakes involved—teams competing for International qualification have strong incentive to play rather than forfeit or request postponements.

Traders should monitor official PGL and Perfect World announcements regarding match confirmation, server stability in the lead-up to 15 June, and any last-minute roster changes affecting either squad. The settlement window closing at 15:00 ET on the scheduled date creates a tight margin; any technical issues or administrative delays occurring after 06:00 ET could trigger the seven-day extension clause. Recent Chinese qualifier tournaments have maintained punctual scheduling, though unforeseen circumstances such as visa issues or equipment failures remain conditional risks that could shift the 50-50 resolution threshold into play.

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.
