Counter-Strike: Grêmio Esports vs ALKA (BO3) - CCT South America Series 4 Group Stage

Platform comparison

Market context

Grêmio Esports lost their Counter-Strike Round 3 match against ALKA at the CCT South America Series 4 Group Stage, with ALKA securing a 2–1 victory in the BO3. The match, scheduled for 19 July 2026, concluded with ALKA winning two maps to Grêmio’s one, confirming ALKA as the match winner.

On Polymarket, this contract is priced at 100% YES for Grêmio winning, a stark contradiction to the on-chain outcome and traditional bookmaker odds, which showed ALKA as the clear favourite with implied probabilities near 74% versus Grêmio’s 26% [1][3]. Comparable cases in esports prediction markets show that when live results contradict crowd pricing, liquidity often corrects within hours once the settlement window verifies the official result. Conditional tokens on Polygon, settled in USDC, will resolve to ALKA unless the platform flags a cancellation or delay beyond seven days, which did not occur here.

Traders should monitor the official CCT South America Series 4 results page and match archives for any post-match disputes or administrative overrides that could alter settlement. No recent news suggests a cancellation or replay, and the match completed within the scheduled window [4]. With the settlement deadline set for 19 July 2026 at 19:00 UTC already passed, the market should resolve to ALKA unless an exceptional administrative error is confirmed by the event organiser.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.
