Maryland Gov. Wes Moore’s office said Sunday that a “mini-Sphere” — a little brother to the famous Sphere in Las Vegas — is planned for National Harbor in Oxon Hill.

Sphere Entertainment Co. is working with Maryland, Prince George’s County and Peterson Companies. This venue would be the second in the U.S., after the Las Vegas venue which opened in 2023.

The proposed venue would be the first smaller-scale Sphere with capacity of 6,000 seats, and feature an Exosphere — the exterior LED display of Sphere that showcases both artistic and branded content, according to a release.

The venue would also include the world’s highest-resolution LED screen, as well as all of Sphere Entertainment’s other technologies such as immersive sound and 4D effects.
