Call of Duty: OpTic Gaming vs 100 Thieves (BO7) - Esports World Cup Playoffs

Platform comparison

Market context

OpTic Gaming meet 100 Thieves in the Esports World Cup Call of Duty playoffs in a best-of-seven semifinal, and the present 0% YES price looks most consistent with the market being effectively stale or already resolved by the time traders are looking at it, rather than a live read on match quality.[2][8][15] The underlying teams have already met at this event: 100 Thieves beat OpTic Gaming 3-2 in the group stage, which is the clearest recent head-to-head reference point for a BO7 rematch.[11][12]

For platform comparison, Polymarket shows this as a binary outcome, so the crowd view is expressed directly as implied probability, whereas Betfair and Smarkets would normally present the same proposition in decimal odds or lay/back prices before fees, which makes the headline numbers look different even when the underlying view is similar. In a market like this, that distinction matters because a 0% reading on one venue can simply mean no active liquidity or no current quotes, while exchange-style books can still display a tradable price until the match starts or settles; this is also where user access and KYC rules diverge, with Polymarket operating as a crypto-native venue and Betfair or Smarkets typically requiring standard identity checks in their supported jurisdictions. The latest preview coverage before the playoff phase had OpTic and 100 Thieves among the leading championship contenders, with OpTic rated slightly stronger in outright terms than 100 Thieves, but not enough to make either side an obvious lock.[5]

The main catalysts are straightforward: whether the semifinal actually started on schedule, whether the match format remained BO7, and whether any tournament delay pushed it outside the settlement window, which would force the 50-50 fallback rather than a team win.[2][8][15] Tournament listings still showed the fixture for 9 August at 14:40 UTC, but traders should watch the official EWC match page or live broadcast schedule for any reshuffle, because settlement here depends on the completed result, not on who was favoured pre-match.[2][15]
