The Worlds 2025 Swiss Stage of LoL has already demonstrated a remarkable level of unpredictability. Day 2 saw CTBC Flying Oyster achieve a significant upset against T1, while Anyone’s Legend managed to overcome Gen.G. G2 Esports also delivered a decisive victory over Movistar KOI. These outcomes have underscored the volatility inherent in the best-of-one format and serve as a reminder that even the most favored teams are susceptible to early setbacks. With the five-round Swiss format, the significance of each match is heightened, as every result now directly influences a team’s path forward.
Worlds 2025 Swiss Stage : Major Upsets Targeting the Big Dogs

Focusing on major upsets, CTBC Flying Oyster’s win over T1 was particularly notable. Chiu “Doggo” Tzu-chuan’s performance on Draven (6/0/12) was instrumental in securing the 25-11 victory within 32 minutes. Teammates Yu “JunJia” Chun-chia and Tsai “HongQ” Ming-Hong also delivered impressive plays on Qiyana and Ryze, respectively. Concurrently, Anyone’s Legend defeated Gen.G 16-10, capturing critical objectives and disrupting Gen.G’s tournament trajectory. G2 Esports similarly displayed strong coordination, defeating Movistar KOI 20-7 in 28 minutes, signaling a resurgence for the European team.
Worlds 2025 Swiss Stage : Regional Clashes and Western Woes

The regional dynamics have added further complexity. While G2’s commanding win contrasted with the struggles of Western teams like Movistar KOI and Fnatic, the LPL’s strength was evident as Bilibili Gaming overcame Fnatic 16-6. As a result, both European teams are now at risk of early elimination. FlyQuest provided a rare highlight for North America with a 26-5 victory over Vivo Keyd Stars, thanks to standout performances from Song “Quad” Su-hyeong and Kacper “Inspired” Słoma. The path ahead remains uncertain, with several favorites now facing significant challenges.

The Swiss Stage format itself has important implications. Advancement to the Knockout Stage requires three wins, while three losses result in elimination. Early upsets—such as those involving CFO and Anyone’s Legend—have placed several prominent teams in jeopardy of an early exit, making every subsequent match critical. In this context, consistency is at a premium, and a single defeat can dramatically alter a team’s prospects.
What’s Next: Matchups to Watch
Looking ahead to Round 3, key matchups include CTBC Flying Oyster versus Anyone’s Legend and Gen.G versus T1. These contests may determine which teams advance and which are relegated to the elimination bracket. With some teams already at 0-2, the competitive field is narrowing rapidly. Western teams must improve their performance to avoid early elimination, while LPL and other regions appear well-positioned to capitalize on the current instability.
Conclusion
In summary, the Swiss Stage of Worlds 2025 has emerged as one of the most unpredictable in recent memory. The early elimination of tournament favorites and the shifting balance of regional power have infused the event with renewed dynamism. As teams compete not just for advancement but for survival, the importance of each draft, ban, and team fight is magnified. The journey to the Knockout Stage promises to remain compelling and highly competitive.
