Sphere Entertainment plans 6,000-seat immersive ‘mini-Sphere’ at National Harbor, targeting a 2030 opening

A new venue concept proposed for the Potomac waterfront

Sphere Entertainment has unveiled plans for a 6,000-seat immersive venue in National Harbor, Maryland, marking the company’s first smaller-format version of its Las Vegas Sphere and its second U.S. location. The project is proposed on roughly eight acres within the National Harbor development, near the existing MGM casino complex, and is being advanced under a signed letter of intent with the site’s developer.

The company has set a target opening year of 2030. Project cost has been described as more than $1 billion, with the National Harbor venue envisioned at roughly one-third the size of the Las Vegas Sphere but at about half the construction cost cited for the Nevada project.

What “mini-Sphere” is designed to deliver

The proposed venue would replicate the core elements of the Sphere model: an interior wraparound LED display intended for large-scale visual environments, advanced spatial audio, and in-seat haptic effects that can be synchronized with content. Plans also include a programmable LED exterior designed to function as a large-format digital display for rotating visual content, including commercial advertising and art installations.

Programming outlined for the National Harbor site includes concerts—potentially using multi-night residencies—along with sporting events such as combat sports, corporate events, and other immersive productions that leverage standardized technical capabilities across venues.

Public incentives and approvals remain central to the timeline

Maryland and Prince George’s County officials have promoted an incentives package tied to the project, described as roughly $200 million in combined public subsidies, tax incentives, and related support. Elements cited include a $40 million public parking garage, as well as additional state and local financing tools that would require approvals and, in some cases, public votes.

Officials have also highlighted projected employment figures associated with the project, including approximately 2,500 construction jobs and about 4,750 longer-term jobs once the venue is operational.

Economic claims, community questions, and regional visibility

Supporters have framed the venue as a regional economic development play, with projections that it could generate about $1 billion annually in economic activity through ticketed events, tourism spillover, and ancillary spending at the waterfront district. At the same time, the project introduces practical questions that typically accompany large-scale entertainment construction, including infrastructure capacity, traffic and parking impacts, and the regulatory conditions tied to public financing.

One likely area of scrutiny is the venue’s LED exterior. Similar large-format displays have raised community concerns elsewhere about nighttime illumination and visual intrusion. Planning discussions for National Harbor are expected to address operating rules for exterior lighting and display schedules.

The proposal positions National Harbor as a test case for a smaller, replicable version of the Sphere concept, with the D.C. region potentially becoming the first market to host a “mini-Sphere” if approvals and financing proceed on schedule.
