A new construction proposal in Maryland could result in the US’ second-ever Sphere entertainment venue, although the project would represent a mini version of the facility previously unveiled in Las Vegas.
The Sphere in Maryland would stand over 300-feet tall and be located near the MGM National Harbor casino property, featuring a construction timeline of three-to-four years and an anticipated cost of more than $1bn.
The Prince George’s County Executive’s Office released a statement once the proposal was obtained by local news outlets, having said, “The county executive and our residents are excited about the potential that Sphere represents for Prince George’s County, but it’s important to be clear: The project is still in the planning stages, and every element must be thoroughly reviewed and approved.
“When approved, Sphere will provide construction jobs, long‑term staffing positions and increased tax revenue. Prince George’s County will be a destination for tourism, which will generate revenue for our restaurants, businesses and hotels. We look forward to the process moving forward and breaking ground.”
Currently, Las Vegas hosts the only Sphere entertainment venue, while a complete replica is also being constructed in Abu Dhabi. Both facilities maintain an 18,000-20,000-seat capacity, compared to the 6,000 seats included within the Maryland proposal.
Funding for The Sphere entertainment venue in Maryland would stem from a public-private partnership, as Prince George’s County will provide $200m, while the remainder will be borrowed against the taxes the development is expected to generate.
A separate parking garage would be built alongside the MGM Grand National Harbor, as well as a sheltered pedestrian bridge to connect the two sites.
Plans for The Sphere in Las Vegas took a hit recently when the rematch between acclaimed boxers Manny Pacquiao and Floyd Mayweather Jr. was suspended indefinitely in late June 2026.
Maryland Lottery and Gaming reported the state’s total sports betting activity for June 2026 on July 10, as operators managed to generate $38.2m of taxable win, equating to a decrease of 17.6%
