Spokane Zephyr W

Aequus Sports was granted a USL Super League franchise on May 16, 2023. On November 4, 2023, the name and crest of the club were announced. Spokane would be the westernmost market in the league's inaugural season, with more West Coast teams planned in later expansions.

Zephyr FC played their inaugural match on August 17, 2024, against Fort Lauderdale United FC to a sold-out crowd on their home field at ONE Spokane Stadium, drawing 1–1. Emina Ekić scored the club's first goal off a penalty kick. In their first season in the USL Super League, Zephyr FC finished 5th and did not qualify for the playoffs due to the head-to-head tiebreaker. In their second season, the Zephyr finished just below playoff qualification with a 10–9–9 record. Attendance at home matches fell from an average of 2,500 in the inaugural season to an announced 1,500 in the second season.

On May 20, 2026, Aequus Sports announced that Zephyr FC would cease operations immediately. The announcement was made by the team's owners to players at a locker room meeting and initially not released to the public. During their tenure in the USL Super League, Zephyr FC had the longest travel distances of any team; their nearest opponents were Dallas Trinity FC at 1,500 miles (2,400 km).
