In what ways must these structures be "like the one in Las Vegas"? Covered in screens?

There are many older sphere-ish-shaped structures:

• Amazon Spheres in Seattle

• ASM Headquarters in Ohio

• Casa Mañana in Texas

• Cinerama Dome in Hollywood

• Cinesphere in Toronto

• Climatron in St. Louis.

• Eden Project in Cornwall

• La Géode in Paris

• Gold Dome in Oklahoma City

• Jeddah Super Dome in Jeddah

• Matrimandir in L'âme de la ville

• Montreal Biosphere in Montreal

• Pusat Sains Negara in Kuala Lumpur

• Science World in Vancouver

• Spaceship Earth (Epcot) in Florida

Does Stockholm's Globen count?

This question is formulated horribly

Just like Ferris wheels, I think some cities will consider the Sphere a must have to attract visitors.

2026 is too soon. It takes 4 years to build something like this

Does this resolve YES if 5 spheres are under construction in cities other than Las Vegas?
Does this resolve YES if 4 spheres are open in cities other than Las Vegas? (And therefore 5 are open in the world?)
