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

Platform comparison

Market context

Nigma Galaxy and OG will face off in a best-of-three Dota 2 match during The International Group Stage on 13 August 2026, with the contest scheduled for 5:00 AM ET. The current Polymarket pricing reflects near-certainty at 100% YES, suggesting traders are pricing in either an expectation of Nigma Galaxy victory or minimal perceived risk of match cancellation. On Polygon, this conditional token contract settles in USDC; a YES resolution pays out if Nigma Galaxy wins, whilst an OG victory triggers the NO token. The settlement window closes at 15:30 UTC on 13 August, allowing roughly ten hours after the scheduled start for match completion and official confirmation.

Historical precedent from prior International tournaments indicates that group stage matches rarely cancel outright, though scheduling delays have occurred due to technical issues or unforeseen circumstances. OG has won The International twice (2018, 2019) and remains a top-tier competitor, whilst Nigma Galaxy—the rebranded Team Liquid roster—has consistently placed among elite teams. The 100% YES probability may reflect either strong market conviction about Nigma's form heading into the tournament or simply low liquidity and sparse trading activity on this specific matchup.

Traders should monitor official Valve and tournament announcements regarding roster confirmations, player availability, and any last-minute scheduling adjustments. Recent esports coverage from sources like Liquipedia and the official Dota Pro Circuit channels will confirm final seeding and match timings as the event approaches. Technical delays during group stage play-ins have historically extended beyond initial time slots; the seven-day postponement clause becomes relevant only if rescheduling extends beyond 168 hours from the original 5:00 AM ET start.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
