Dota 2: OG vs GLYPH (BO1) - BLAST Slam Group Stage

Platform comparison

Active sub-markets

Market context

OG face GLYPH in a best-of-one group stage match at the BLAST Slam on 28 May, with the fixture scheduled for 07:30 ET. The match represents a significant test of OG's current roster composition following their roster adjustments earlier in 2025, whilst GLYPH continue to establish themselves within the competitive Dota 2 circuit. Both teams will be competing for positioning within the group stage bracket, where early results typically carry weight for seeding implications.

The 100% crowd probability reflects OG's historical standing as a two-time International champion with sustained competitive infrastructure, though this metric warrants scrutiny given the volatility inherent in single-elimination Dota 2 fixtures. Recent BLAST Slam tournaments have demonstrated that established organisations can struggle against emerging rosters when preparation gaps exist or meta adaptation lags. The absence of recent head-to-head data between these specific lineups means traders should weight OG's broader tournament performance and coaching staff continuity against GLYPH's recent LAN placements and scrim results, which remain opaque to public analysis.

Key variables affecting settlement include confirmation of both teams' final rosters by the scheduled fixture time, as roster changes or player illness have disrupted BLAST events previously. The seven-day grace period for delays provides buffer against minor scheduling disruptions, though extended postponements remain possible given international travel dependencies. Traders should monitor official BLAST communications and team social media for any announcements regarding preparation status or unexpected absences in the 48 hours preceding the match.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
