A proposal to simulate the experience of standing on the Moon inside a giant spherical structure once captured imaginations before quietly disappearing. That concept never got off the ground, but four years on, the team behind it has returned with something far bigger — a full Smart City Masterplan and a vision that makes the original look modest by comparison.
Toronto-based Moon World Resorts Inc. went public with the new concept in February 2026, calling it simply Moon. Each development carries an estimated price tag of $5 billion, and while no site has been locked in yet, the company has named ten countries as candidates for regional licensees: Australia, Brazil, China, Egypt, India, Poland, Spain, Thailand, the United Arab Emirates, and the United States. Saudi Arabia, notably absent from the list, still feels like an obvious fit for something this audacious.

The structural ambition alone is staggering. The central building would be a true sphere — 271 meters wide and 312 meters tall — making it the largest and tallest of its kind anywhere in the world. For context, Las Vegas’ Sphere, itself a marvel of engineering, measures 157 meters across and rises just 112 meters. Moon isn’t playing in the same league; it’s playing a different sport entirely.
Inside, the resort would be anchored by a 4,000-room all-suite five-star hotel, with a convention center, restaurants, wellness facilities, an e-sports hub, and a boutique hotel all occupying the ground level. The crowning feature, though, would be a simulated lunar surface and base positioned above it all — an “authentic” recreation of what walking on the Moon might feel like, reportedly capable of hosting up to two million visitors a year. The method for achieving that effect remains, for now, a mystery.
On the outside, 20 towers would ring the sphere, connected by a panoramic elevated walkway that renders suggest will be lined with solar panels along the top. Sixteen smaller spherical structures are also planned nearby, creating a campus-like complex that would reshape the skyline of whichever city claims it.
The broader development extends well beyond the sphere itself, incorporating a transit hub, heliport, vertiport, parking infrastructure, and 10,000 luxury branded residences set among generous green space. Moon World Resorts estimates construction would take around 60 months, pointing to a potential opening as early as 2032 — assuming everything moves quickly on a project that, at this stage, remains largely conceptual. Ambition is clearly not in short supply here, but the leap from striking renders to a working lunar resort is a long one.
