The team will remain under the management of Brian Schmetzer in his ninth full MLS season as head coach of the Sounders.

The Sounders will play a minimum of 42 total matches in MLS competitions, domestic cups, and two international tournaments organized by FIFA and CONCACAF.

The team also won the 2022 CONCACAF Champions League and qualified for the 2023 FIFA Club World Cup under his tenure, which led to a multi-year contract extension in 2024.

[1] The Sounders played a total of 47 matches during the 2024 season across several competitions and finished with an overall record of 22 wins, 13 losses, and 12 draws.

[8][9] The Sounders announced a major trade with FC Dallas on January 8, 2025, to acquire American forward Jesús Ferreira in exchange for Brazilian midfielder Léo Chú, an international roster slot, and up to $2.3 million in conditional general allocation money.

On January 13, the Sounders signed midfielder Paul Arriola from FC Dallas in a trade for their 2026 MLS SuperDraft first-round pick and up to $300,000 in general allocation money.

[14] The team traveled to the Marbella Football Center in Spain on January 20 to begin the second stage of their preseason, which would include matches against European clubs.

The final two matches of the three-week camp were played against Swedish sides IFK Norrköping and Hammarby IF on the same day; both ended in draws.

[19][20] The team returned to the Longacres training facility on February 6 and played their final preseason friendly, against Louisville City FC of the USL Championship.

The jersey includes the Southern Lushootseed phrase x̌ax̌aʔ ti qʷuʔ and its English translation ("water is sacred") on the front and a stylized orca tail on the back.

[22] The Sounders are scheduled to open the season in February with the first round of 2025 CONCACAF Champions Cup in a home-and-away series against Guatemalan club Antigua GFC.

[8] The MLS regular season begins at the end of the month and will include a break for part of the FIFA Club World Cup in June.

For transfers out, dates listed are when Seattle Sounders FC officially removed the players from its roster, not when they signed with another club.
