The Continental Hockey League (KHL) and the National Hockey League (NHL) are the two strongest hockey leagues in the world. The KHL was founded in 2008 and includes teams from Russia and other Eurasian countries. The NHL, founded in 1917, is the oldest and most prestigious league, based in North America.

Quantitatively, the NHL significantly surpasses the KHL: the NHL has 32 teams (as of 2024), while the KHL has 24. In terms of player quality and infrastructure, the NHL is also considered the stronger league, as it features the best hockey players in the world. However, the KHL is actively developing and attracting global hockey stars.

In terms of achievements, the NHL has a richer history: 104 seasons and 105 Stanley Cup tournaments, while the KHL has completed 16 seasons and awarded the Gagarin Cup. The NHL's popularity is higher worldwide, but in Russia and post-Soviet countries, the KHL is the national league with a large audience.

The value of the properties differs markedly: the NHL is valued in the billions of dollars, with teams worth from $400 million to $2 billion. In the KHL, club values are significantly lower, typically ranging from $10 to $50 million. NHL budgets are 10–20 times larger than those of KHL clubs.

Despite the differences, the KHL and NHL actively compete for players and fans. The KHL focuses on developing homegrown talent and attracting NHL veterans, while the NHL remains the gold standard of world hockey. The choice between the leagues depends on priorities: for career growth and maximum competition, the NHL; for comfortable play in a familiar environment, the KHL.
