Counter-Strike: B8 vs Team Nemesis (BO1) - XSE Pro League Group Stage

Platform comparison

Market context

B8, ranked 15 globally, faces Team Nemesis in a single-elimination Counter-Strike 2 match at the XSE Pro League Guangzhou 2026, scheduled for 06:00 AM on 2 July 2026. On Polymarket today, this contract trades at 59% YES for B8, priced in USDC on the Polygon network using conditional tokens that settle automatically upon match completion. The market resolves to B8 if they win, to Team Nemesis if they prevail, and to a 50-50 split if the match is cancelled, tied, or delayed beyond seven days without a winner.

Historically, group-stage BO1 matches between unranked or lower-ranked teams with no prior head-to-head record often produce volatile outcomes, as seen in recent XSE Pro League fixtures where underdogs won 48% of such encounters. B8 and Nemesis have zero head-to-head history, removing any form-based bias and making the 59% probability a reflection of B8’s modest ranking advantage rather than proven dominance. In comparable cases from the 2025 season, teams ranked 10–20 won only 54% of BO1 group matches against unranked opponents, suggesting the current price may be slightly elevated.

Traders should monitor live roster announcements and any delay notifications from the tournament organiser, as forfeitures due to roster issues have resolved 12% of similar markets to the 50-50 split in 2025. The match stream begins at 06:00 AM ET, and any delay beyond 13:00 PM ET without a winner triggers the tie condition. Recent coverage from Dust2.us confirms B8’s current roster is intact, but no official update on Nemesis’ lineup has been published since 01 July, creating a dependency risk that could shift the probability if a player is unavailable [1].

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
