Counter-Strike: 1WIN vs Butterfly (BO3) - NODWIN Clutch Series Playoffs

Platform comparison

Market context

The match between **1WIN and Butterfly** is the live issue, with the market sitting at **50%** after the scheduled playoff slot has already moved into the day’s action window. In practical terms, that leaves the price close to a coin-flip unless there is a clear sign that one side has missed the start, withdrawn, or surrendered the series.

Recent results give little reason to treat either team as dominant. Butterfly beat 1WIN **2-1** in their last recorded meeting on 30 July in the CCT Europe playoffs, while broader market data from that match had 1WIN as a modest favourite before Butterfly closed it out. NODWIN Clutch Series #10 is a **single-elimination BO3 playoff** bracket, so there is no second chance once the series starts, and both teams have already shown they can win this pairing over a three-map format.[2][3][6][7]

For traders, the main catalysts are simple: whether the teams actually load into the server, whether the organiser publishes a revised bracket or start time, and whether there is any forfeit or technical issue that prevents completion. The market’s rule set also matters: if the match is not played, ends level, or drifts more than seven days beyond the scheduled date without a winner, it resolves **50-50** rather than to either side. The only strong directional move from here would come from a confirmed result or an official match-status update, not from pre-match form alone.[5][6]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
