Sphere Entertainment plans to build a new, immersive venue at National Harbor, Maryland. This will be the second Sphere in the United States and the first to use a smaller-scale design.

A new Sphere could rise at National Harbor under a proposal announced Sunday, a project officials say could become a new regional landmark and one of the largest economic development efforts in Prince George’s County history.

The 1st Sphere opened in 2023 in Las Vegas. Leaders are working on creating a 2nd Sphere on a smaller scale in National Harbor.

Sphere Entertainment plans a new venue at National Harbor, with a 6,000-person capacity and advanced tech, set to boost the local economy.

Revenue from the proposed Sphere entertainment venue at National Harbor in Maryland would far exceed that generated from the Washington Commanders and Six Flags, according to the Prince George’s County executive.

Digital renderings of the plan show the massive globe -- with a projection of planet Earth -- parked atop Lot B outside MGM's National Harbor Hotel and Casino.

Amid all the celebration, praise and hope for the mini Sphere proposed for National Harbor, one key Maryland voice was missing: Its very big neighbor.

Sphere Entertainment says it plans to build its first smaller-scale version of the Sphere at National Harbor in Maryland.
