Market context
The semifinal is a best-of-three between 1WIN and Butterfly, and the market at 50% is effectively pricing a coin-flip before vetoes and map selection are known. That is not a strange starting point for a playoff pairing that already has recent direct evidence: Butterfly beat 1WIN 2-1 in their most recent meeting on 30 July in CCT Europe Series #5, while 1WIN had looked the stronger side in some pre-match pricing before losing the series. [4][8][9]
For a comparable frame, both teams have shown enough short-term form to justify a tight line rather than a clear favourite. 1WIN have recently been described as sitting around a 75% win rate over the last month, with strong Dust2 numbers but a notably weak Nuke profile, while Butterfly have posted roughly a 71% win rate over the recent month and half-year and tend to lean on more comfortable map choices. [2] In playoff BO3s, those map-specific edges matter more than raw ranking or a single recent result, because one bad veto can force a team onto its weakest ground. [2][7]
The main trader catalysts are whether the scheduled start holds, whether either side announces a roster change, and whether the published bracket order still places this as Semifinal 2 at the expected time. Liquipedia lists the NODWIN Clutch Series #10 playoffs as a single-elimination BO3 bracket on 6 August, while the market description itself warns that cancellation, tie, or a delay beyond seven days would push settlement to 50-50. [3][7] With no recent beat-reporting on late roster news in the supplied results, the most practical watchpoints are official team socials, tournament lobby updates, and any last-minute substitution or forfeit notice before the 18:45 UTC settlement window.

FAQ
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
