Market context

BetBoom Team and GamerLegion are scheduled to compete in a best-of-one Counter-Strike match during the IEM Cologne Major Stage 2 on 6 June at 1:30PM ET. In prediction markets, a YES share represents a bet that BetBoom Team will win; a NO share bets on GamerLegion. The settlement window closes on 7 June at 00:30 UTC, allowing roughly 23 hours after the scheduled start time for the match to conclude. Should the match fail to produce a winner within seven days—whether through cancellation, tie, or extended delay—the market resolves to 50-50, splitting winnings equally between both sides.

The 100% implied probability for BetBoom Team reflects either incomplete market data or a technical condition rather than genuine certainty. Historical precedent from major Counter-Strike tournaments shows that Stage 2 matches at IEM events rarely fail to complete, though technical issues and scheduling conflicts have occasionally forced rescheduling. GamerLegion's recent form and roster stability matter considerably; the team has competed inconsistently across 2024–2025 qualifiers, whilst BetBoom Team has maintained stronger consistency in regional play.

Traders should monitor official IEM Cologne announcements for any schedule shifts, roster changes, or technical warnings in the 48 hours preceding the match. Visa delays, player illness, or equipment failures have historically disrupted major tournament matches. The current probability skew warrants scrutiny—verify whether this reflects genuine analytical consensus or a liquidity artefact before committing capital.

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.
