Overview
- The team publicly unveiled the Cleveland Sirens at Rocket Arena on Tuesday, Aug. 4, 2026, revealing a logo, color palette and the motto “Hear the Call.”
- Rock Entertainment Group, owned by Dan Gilbert, paid a reported $250 million expansion fee and will house the Sirens at Rocket Arena with separate day‑to‑day operations from the Cavaliers.
- Ownership said the name followed about 13 months of market research, surveys and thousands of community conversations designed to tie the brand to Lake Erie and Northeast Ohio.
- The organization filed a trademark for Cleveland Sirens on May 15, 2026 through CLE Travel Sports, LLC, and sources say pre‑announcement talks limited immediate conflict with another league’s Sirens name.
- The reveal follows strong local demand and commercial momentum — the team reported roughly 8,500–9,000 season‑ticket deposits and announced founding partners — as the Sirens begin roster building and community activations for 2028.
