Dota 2: Aurora vs GamerLegion (BO3) - The International Group Stage

Platform comparison

Market context

Aurora and GamerLegion are scheduled to contest a best-of-three match in The International Group Stage on 13 August at 1:00 AM ET. The fixture represents a critical early-stage encounter where both squads will attempt to establish momentum in a tournament format that determines seeding for subsequent playoff rounds. Group stage results directly influence bracket positioning, making even opening matches consequential for deep tournament runs.

The 100% crowd-implied probability reflects either exceptional confidence in one team's superiority or, more likely, uncertainty regarding match completion itself. The International's scheduling has historically been subject to delays and technical complications; the seven-day grace period built into settlement terms acknowledges this operational reality. Previous iterations of the event have seen matches rescheduled due to server issues, player connectivity problems, or administrative adjustments. Traders should note that a 100% reading on a match that hasn't yet occurred typically signals either missing information about team availability or genuine concern that the match may not proceed as scheduled.

Key variables to monitor include official confirmation of both rosters in the 48 hours preceding the fixture, any announcements regarding stand-in players or last-minute substitutions, and Valve's published schedule updates. Recent Dota 2 competitive announcements should be cross-referenced against both organisations' social media channels for withdrawal notices or logistical issues. The settlement window closes 13 August at 12:10 UTC, providing a narrow window for resolution. Any postponement announcement after that timestamp would trigger the 50-50 resolution clause, making pre-match confirmation critical for traders holding positions.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
