On what date did Nintendo reveal Raiders' release date?

Nintendo revealed Splatoon Raiders’ release date on April 21, 2026. A new trailer confirmed that the Switch 2 spinoff would launch on July 23, 2026, ending the period when its release window was still unannounced.

Raiders had originally been revealed as a Nintendo Switch 2 exclusive in June 2025, but Nintendo did not immediately provide a specific launch day. The April 21 announcement therefore supplied an important new detail: players could finally mark the July release date on their calendars. The game later launched as a single-player-focused adventure with optional online and local-wireless co-op.

A common mix-up is confusing the reveal date with the release date. April 21, 2026, was the day Nintendo announced the date; July 23, 2026, was the day the game launched. June 10, 2025, refers to the earlier reveal period for the project, not the later release-date announcement.
