Dota 2: OG vs HULIGANI (BO3) - The International Group Stage

Platform comparison

Market context

The International 2026 Group Stage will feature a best-of-three Dota 2 encounter between OG and HULIGANI on 14 August at 22:00 ET. In prediction markets, a YES share represents a bet that OG will win this match; a NO share bets on HULIGANI's victory. The current crowd-implied probability of 100% YES indicates traders are pricing OG as near-certain favourites, though the settlement window extends to 15 August at 08:00 UTC to account for scheduling variations.

OG's historical dominance in The International tournaments—including two championship titles in 2018 and 2019—establishes a baseline expectation of competitive strength at this event. HULIGANI, by contrast, operates as a regional qualifier team with substantially fewer high-tier LAN appearances. Comparable Group Stage matchups between established organisations and emerging squads typically favour the former by wide margins, though upsets do occur when preparation gaps narrow or meta shifts favour unconventional strategies. The 100% probability reflects confidence in OG's baseline superiority rather than absolute certainty.

Key variables for traders include official confirmation of the match schedule, any roster changes announced before 14 August, and live performance data from earlier Group Stage rounds. The International 2026 format and participating teams have been announced, but patch notes or last-minute substitutions could alter competitive dynamics. If the match is postponed, rescheduling must occur by 28 August at 23:59 ET; cancellation or a tied result would trigger a 50-50 resolution. Monitor official Valve communications and team announcements for disruptions to the scheduled fixture.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
