The Company’s first Sphere opened in Las Vegas on September 29, 2023. The venue can accommodate up to 20,000 guests and can host a wide variety of events year-round, including The Sphere ExperienceTM, which features original immersive productions, as well as concerts and residencies from renowned artists, and marquee sports and corporate events.
