Although LA won, their path to the title involved narrow escapes. In the Eastern Conference Final, they upset Toronto FC in a tense final. For bettors backing Toronto at home, the result was a costly shock given the Impact's strong season.
Houston was favored to advance but struggled against a disciplined Red Bulls side. The eventual loss in extra time underscored the difficulty of betting on physical, defensive-heavy teams in the postseason, leading to unexpected payouts.
San Jose, having won the cup the previous year, was not heavily favored in Chicago. The Earthquakes won 3-1 in a defensive struggle, surprising bettors who expected a tighter contest given the Fire's strong home record.

RSL won on penalties after a 0-0 draw. While not a straight win, the failure of New York to convert chances against a resilient RSL side was costly for bettors who favored the Red Bulls' attacking prowess in a high-pressure game.
Sporting KC won 2-0 at home, but the upset narrative often focuses on DC's inability to capitalize. However, in reverse contexts, heavy favorites like LA Galaxy or Seattle have lost to underdogs, highlighting the financial risk of backing favorites in knockout stages.
