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

Market context

OG face GLYPH in a best-of-one Dota 2 match at the BLAST Slam Group Stage, scheduled for 28 May at 07:30 ET. The conditional token contract on Polymarket currently prices OG's victory at 100%, reflecting the substantial skill differential between the two rosters. OG, a two-time International champion with a stable core, operates at a fundamentally different competitive tier than GLYPH, an emerging roster competing in regional circuits. The 100% implied probability on-chain suggests traders view a GLYPH upset as negligible; the USDC settlement mechanism on Polygon will execute once the match concludes and the result is verified.

Historical precedent from Dota 2 group-stage matches shows that extreme probability skews (95%+) typically persist when established tier-one teams face developing squads, particularly in single-elimination formats where preparation time is limited. GLYPH's recent performances in secondary tournaments have not demonstrated the consistency required to threaten OG's playmaking or macro execution. The group-stage format itself—offering no second chances—compounds the pressure on the underdog.

Traders should monitor BLAST's official schedule for any postponements beyond the 7 May settlement window, which would trigger a 50-50 resolution. Roster changes or last-minute stand-in announcements from either team could shift the contract, though OG's organisational stability makes this unlikely. The match's timing at 07:30 ET places it early in the tournament day; any technical delays or server issues would be resolved within the settlement window given BLAST's infrastructure standards.

For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
