Counter-Strike: 1WIN vs Butterfly (BO3) - CCT Europe Series #5 Playoffs

Platform comparison

Market context

1WIN and Butterfly are playing a best-of-three knockout match in the CCT Europe Series #5 playoffs, and the market’s 51% YES price implies 1WIN are only a very slight favourite at the time of writing. Public match listings show 1WIN around 1.733 decimal and Butterfly around 1.938, which is broadly consistent with a near coin-flip once normalised for the bookmaker margin[1]. Liquipedia places the playoff stage on 30 July–2 August and confirms all knockout matches are Bo3, so the relevant settlement risk is not map count but whether the series is actually completed as scheduled[3].

For a platform comparison, Polymarket-style markets quote an implied probability, while Betfair and Smarkets are usually read through decimal odds and exchange commission, so a 51% prediction-market price can still correspond to a tighter trading edge once fees and back/lay spread are included. Kalshi’s event contracts also settle on a binary outcome, but accessibility and KYC are typically more restricted by jurisdiction than on open exchanges, so comparable prices may not be directly fungible across venues. Recent schedule pages still show the fixture as a live or scheduled playoff Bo3 on 30 July, which means traders should watch for lineup changes, postponements, map veto delays, or forfeits rather than expecting format risk to move the market materially[1][2][3].
