Counter-Strike: Infinite vs 100 Thieves (BO3) - Esports World Cup Open Qualifier Play-Ins

Platform comparison

Market context

The market is pricing **100 Thieves** at about **70% implied probability**, leaving **Infinite** as a roughly **30% underdog**. The consensus view is clearly that 100 Thieves should win this best-of-three, but a 30% YES price on Infinite is not negligible in a qualifier setting where BO3 variance, veto swings and schedule chaos can still matter.

The historical frame points towards the favourite being respected, not locked in. 100 Thieves sit higher in the visible rankings on match listings and have the stronger market support, while Infinite’s recent results have been mixed, with wins over Giant Pandas and Aogiri offset by losses to Betclic, SPARTA and HOTU.[3][12] Comparable pricing in esports qualifiers often reflects roster strength more than tournament fragility: when a higher-profile side is around 1.20–1.40 in outright terms, the underdog still needs only one favourable map to keep the series live, so value can sit on the dog if the veto is awkward or if the favourite has shown recent inconsistency.[13][17]

For traders, the main catalysts are whether the match actually starts on time and whether the bracket remains intact. The event is listed for 09:00 with the broader Esports World Cup Open Qualifier running across 9 August, and live schedules still show the pairing as upcoming rather than completed.[2][6][8] That matters because any late withdrawal, postponement beyond the settlement window, or match abandonment can push the market towards the 50-50 fallback rather than a clean winner call, so the key watchpoints are official start confirmation, roster lock, and any bracket rescheduling around adjacent qualifier fixtures.[2][9][11]
