Market context

Team Refuser face Game Master in a lower bracket quarterfinal best-of-three at the International China Closed Qualifier Playoffs on 17 June. The match determines progression toward qualification for The International, Dota 2's premier annual championship. Polymarket currently prices this contract at 100% YES, implying certainty that the match will occur and produce a decisive outcome by the settlement deadline of 10:00 UTC on 17 June. This pricing reflects the scheduled fixture time of 00:00 ET (05:00 UTC), leaving a five-hour buffer before settlement closes.

Historical precedent from regional Dota 2 qualifiers shows lower bracket matches rarely cancel outright, though technical delays and server issues have occasionally extended play beyond initial windows. The China Closed Qualifier format typically maintains strict scheduling discipline to accommodate multiple concurrent matches. Team Refuser and Game Master are both established Chinese organisations with consistent participation records, reducing forfeit risk. However, the 100% probability leaves no margin for unforeseen disruptions—venue issues, player unavailability, or administrative delays would trigger the 50-50 tie resolution clause.

Traders should monitor official qualifier announcements from PGL or the organising body for any schedule adjustments in the 48 hours before match time. Recent Chinese regional qualifiers have proceeded on schedule despite external pressures. The key catalyst remains confirmation that both teams field complete rosters and that broadcast infrastructure is operational. Any announcement of postponement beyond 7 days from 17 June would automatically resolve this contract to 50-50, fundamentally altering the current pricing.

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.
