Friedberg’s prediction is that the Las Vegas Sphere concept will lead to dozens of similar immersive venues worldwide within roughly a decade after 2023.

As of November 30, 2025:

• There is one operational Sphere in Las Vegas, opened in September 2023.(en.wikipedia.org)
• A second full‑scale Sphere in Abu Dhabi has been formally announced via a partnership between Sphere Entertainment and Abu Dhabi’s Department of Culture and Tourism, with Abu Dhabi confirmed as the second location.(investor.sphereentertainmentco.com)
• Earlier plans for a major London Sphere were withdrawn in January 2024 after planning permission issues.(en.wikipedia.org)
• Abu Dhabi’s deal gives it exclusive rights to develop additional Spheres across the Middle East and North Africa, but these are only options, not yet specific, funded projects.(thenationalnews.com)
• Sphere Entertainment is exploring smaller, cheaper “mini‑Spheres” and broader immersive deployments, but as of now no concrete sites or build schedules have been committed publicly.(theverge.com)
• Other immersive dome venues (e.g., Cosm in California and Texas) indicate a broader move toward Sphere‑like experiences, but they do not yet amount to “dozens” of venues clearly derived from the Las Vegas Sphere model.(apnews.com)

Only about two years have elapsed since the prediction, and his normalized horizon is roughly ten years after 2023 (through ~2033). With at least one confirmed additional Sphere and contractual frameworks for more, expansion is underway but still in an early phase and far short of “dozens” so far. However, there is no decisive evidence yet that such growth cannot occur over the remaining ~8 years.

Because the prediction’s timeline has not yet expired and current evidence neither guarantees nor rules out reaching “dozens” of Sphere‑like venues by around 2033, the outcome is too early to call.
