LoL: T1 vs Karmine Corp (BO5) - Mid-Season Invitational Play-In

Platform comparison

Market context

The real-world event is the upper bracket final of the Mid-Season Invitational Play-In, where T1 face Karmine Corp in a Best of 5 series for the League of Legends title. In prediction markets, a YES share pays out if T1 win the match, while a NO share pays out if Karmine Corp win or the match is cancelled. The market currently implies a 62% chance of a T1 victory, reflecting strong confidence in the Korean side despite Karmine Corp’s recent 3-0 sweep of Deep Cross Gaming to reach this stage[6].

Historically, T1’s dominance in MSI play-ins mirrors their record in previous years, having attended their fifth consecutive MSI alongside G2, with both teams qualifying for twice as many MSIs as any other squad[2]. Past encounters show T1 winning decisively, including a 1-0 victory in December 2024, and Strafe users currently predict an 81.3% chance of T1 winning this specific match[1][4]. This pattern suggests the 62% market probability may be conservative compared to historical performance and community sentiment.

Traders should monitor official MSI announcements for any schedule changes, as the match is set for 29 June at 03:00 UTC, and watch for in-game patch updates like the current 26.13 patch which could shift team strategies[3]. Karmine Corp’s Fearless Draft success against DCG indicates tactical flexibility, but T1’s 3-0 sweep of Team Liquid earlier in the Play-In reinforces their status as tournament favourites[8]. Any delay beyond seven days or cancellation would resolve the market to a 50-50 split, making timing a critical dependency.
