LCS representatives Team Liquid and Cloud9 exited the Swiss stage via upsets, leaving LYON as North America's final contender at 2-2 entering the October 31 best-of-three decider. Traders assign 99.6% implied probability to a North American team reaching the quarterfinals because LYON's recent form, roster depth, and favorable regional seeding create a strong edge in the elimination matchup against another 2-2 side. The Swiss format rewards consistent series wins, and historical LCS performance in similar spots supports the consensus. Upset losses remain possible due to patch volatility, individual player variance, or stylistic mismatches in best-of-three play, though such outcomes would require significant deviation from current results.
