CLEVELAND — Cosm, along with Bedrock and Rock Entertainment Group, have broken ground on a new entertainment venue located at the intersection of East 4th Street, Prospect Avenue and Huron Road in downtown Cleveland.
Dubbed Cosm Cleveland, the venue will sit directly across from Rocket Arena (formerly Rocket Mortgage Fieldhouse), home of the NBA’s Cleveland Cavaliers and AHL’s Cleveland Monsters. The two professional sports franchises are owned by Dan Gilbert, founder of Rocket Mortgage, Bedrock and Rock Entertainment Group.
Spanning approximately 64,000 square feet and rising three stories, Cosm Cleveland will comprise two programmatic elements: The Dome and The Hall. Through Cosm’s proprietary technology called Shared Reality, the venue will merge a stadium-like atmosphere with state-of-the-art visuals in a communal setting.
Rossetti Architects designed Cosm Cleveland, and Bedrock is leading the development. The venue, which will anchor Bedrock’s Rock Block mixed-use development, is slated to open in 2027.
“This is a major milestone for our downtown Gateway District, and the arrival of Cosm is a testament to our community’s spirit and resilience,” says Cleveland Mayor Justin Bibb. “This incredible venue will enhance our city’s reputation as a hub for sports and entertainment, drawing visitors from near and far to experience a whole new level of immersive entertainment.”
Cleveland represents Cosm’s fifth venue. Last year, the company announced a fourth location in Detroit, which broke ground at Bedrock’s development at Cadillac Square in April 2025. Cosm has also opened two venues in Los Angeles (Hollywood Park) and Dallas (Grandscape), and recently began the development of its venue in Atlanta (Centennial Yards).
Expanding on the foundational design of its first four venues, Cosm Cleveland will include a 12,000-plus LED dome with a hi-resolution wall-to-wall LED display.
With its planned programming, Cosm Cleveland will showcase live sporting events, select movies like “The Matrix” and immersive/experiential content.
Additionally, Cosm Cleveland will feature a presentation of Cirque du Soleil’s production of “O,” along with other entertainment offerings like live music and performances.
“This venue will be more than just a destination,” says Jeb Terry, president and CEO of Cosm. “It will be a new way for Clevelanders to come together and experience the moments that matter most.”
