Resolution Criteria

This market resolves based on a poll voted on by other users. Voters should evaluate which team has the strongest historical record across championships, playoff success, and sustained excellence. Key metrics include:

• Championships: Seahawks won Super Bowl XLVIII in 2014; SuperSonics won the NBA championship in 1979; Sounders won the 2022 CONCACAF Champions League and 2025 Leagues Cup; Metropolitans won the Stanley Cup in 1917

• Playoff appearances and division titles: Seahawks have won 12 division titles and three conference championships; SuperSonics won Western Conference titles in 1978, 1979 and 1996 with six divisional titles; Mariners won three American League West Division titles with an unforgettable 1995 playoff run and 2001 squad winning 116 games

• Kraken: Made the 2023 Second Round in playoffs

Background

The Seahawks, SuperSonics, Sounders, and Mariners were all established in the 1960s-1970s, while the Kraken joined the NHL in the 2010s. The SuperSonics relocated to Oklahoma City in 2008, ending the franchise's Seattle tenure. The 2001 Mariners tied the MLB record with 116 wins in a single season, though they've never won a World Series.

Considerations

The SuperSonics' 1979 championship remains Seattle's only major professional basketball title, but the team no longer exists. The Seahawks' single Super Bowl victory is their only championship, though they've had sustained playoff success. The Sounders have won multiple MLS titles and international competitions in recent years, representing the city's most successful current franchise. The Mariners have never won a World Series despite historic regular seasons.
