Mini‑Sphere venue planned near D.C.'s National Harbor

Sphere Entertainment proposes a 6,000-seat 'mini‑Sphere' immersive venue at National Harbor in Maryland aiming for a 2030 opening, supported by roughly $200 million in proposed public incentives that include measures requiring voter approval.

Sphere Entertainment unveiled plans for a 6,000-seat "mini‑Sphere" venue at National Harbor, Maryland, with a proposed opening in 2030. The company says the smaller dome would offer the same immersive features as its Las Vegas Sphere at about one‑third the size. Officials and company executives described the project as the first in a planned global network of mini‑Spheres. Maryland leaders and local developers have negotiated a package of public incentives and a letter of intent, but some measures still require formal approval. Key details: - The proposal calls for a 6,000-seat immersive dome at National Harbor near an existing casino and entertainment complex, with the company targeting a 2030 opening. - Sphere and officials say construction would cost more than $1 billion and cited roughly $200 million in public subsidies and tax incentives to help offset expenses. - Several incentives would require voter approval, including $10 million in state financing, potential forgoing of up to $130 million in future local tax revenue, and construction of a $40 million public parking garage, according to officials. - Company and state statements estimate about 2,500 construction jobs and 4,750 long‑term jobs tied to the project, and the company projects roughly $1 billion in annual economic activity from the venue. - The dome would feature an LED "Exosphere" for advertising and art and is described by officials as suited for immersive concerts with in‑residence artists, sporting events, and corporate functions. Summary: If approved, the mini‑Sphere would add a large immersive entertainment venue and new jobs to the National Harbor area while relying on a package of public incentives that require additional approvals. A letter of intent exists with local developers and officials have highlighted potential economic benefits; final votes and funding decisions are undetermined at this time.
