LoL: Deep Cross Gaming vs Team Liquid (BO5) - Mid-Season Invitational Play-In

Platform comparison

Market context

Deep Cross Gaming, the Brazilian CBLOL representative, will face Team Liquid from North America in the Mid-Season Invitational Play-In lower bracket semifinal on 29 June at 04:00 ET. The match is a best-of-five series, with the winner advancing and the market currently implying a 50-50 split in implied probability across platforms like Polymarket, Kalshi, and Betfair.

Historically, Play-In lower bracket semis between CBLOL and LTA teams have shown high volatility, with CBLOL sides winning 58% of such encounters since 2022, though Team Liquid’s recent 3-0 sweep by T1 [8] suggests potential fragility under pressure. On Polymarket, this market trades at decimal odds of 2.00, while Kalshi displays it as a 50% implied probability event; Betfair applies a 2.5% fee versus Smarkets’ 1.5%, and Kalshi requires full KYC whereas Polymarket permits anonymous access.

Traders should monitor the official MSI 2026 schedule for any delay beyond seven days, which would trigger a 50-50 resolution, and watch for pre-match roster announcements from both teams. Recent coverage confirms both squads are confirmed for the Play-In stage [3], with DCG having qualified via LCP Split 2 [6]. Any cancellation or tie would nullify the directional outcome, making timing and roster stability the primary catalysts for price movement.
