On the afternoon of April 14, the Las Vegas Strip got a new kind of spectacle: cellphone video of a lone figure standing on top of the Sphere, the 366-foot-tall, $2.3 billion entertainment dome just east of the Venetian. A helicopter hovered overhead while crowds filmed from resort windows and sidewalks, and social feeds quickly lit up with one big question: was that world-famous climber Alex Honnold on the roof of Vegas' giant glowing orb?
Given Sphere's slate of large-scale immersive projects and the obvious coordination involved, many observers are treating the episode as part of a planned production rather than a spur-of-the-moment stunt.
What the video shows
Cellphone footage reviewed and distributed by Storyful shows a person standing on the Sphere's outer shell while a helicopter circles above. The clip, credited to a user identified as "Jedi Rich," spread quickly across social platforms as bystanders posted what they had captured.
The images match eyewitness accounts from the Strip and immediately triggered a wave of online guesses that the climber was one of the world's best-known free soloists. The framing of the shot, the high vantage point, and the coordinated air support all added to the sense that this was not some random dare, but a choreographed moment.
Connected to Sphere's 'From the Edge'
Sphere Studios has already announced a project that seems tailor-made for what viewers saw over the weekend. The company is producing a film titled From The Edge, directed by E. Chai Vasarhelyi and Jimmy Chin, featuring five extreme athletes, including rock climber Alex Honnold.
Sphere Studios says filming is underway in several locations, among them Las Vegas, and that the production will use the company's ultra high-resolution "Big Sky" camera system to capture imagery suited for the venue's 16K display. The production announcement outlines the athletes involved and the overall shooting plan, and the timing of that work lines up with the apparent climb on the Sphere.
Why people suspect Honnold
According to SFGATE, the climber in the video "appears to be Alex Honnold," and the scope of the Sphere project makes that a reasonable guess rather than pure wishful thinking. Honnold, who now lives in the Las Vegas area, has been in the spotlight recently for high-profile urban climbs.
In January he free soloed Taipei 101, one of the tallest skyscrapers in the world, a feat covered in detail by the Los Angeles Times. That headline-grabbing ascent, combined with his listed role in From The Edge, helps explain why so many viewers immediately tagged him as the mystery figure atop the Sphere.
Past climbs and local concerns
This is not the first time someone has made it to the Sphere's skin. In February 2024, a man who climbed the dome as part of a protest was detained, an incident documented by the Associated Press. That case led to criminal charges and a quick response from police, a clear reminder of how fast authorities move when someone starts scaling a structure like this.
Whether the latest episode turns out to be a fully authorized shoot or an unapproved stunt, the safety issues are the same. Unsecured climbers and hovering aircraft above a busy tourist corridor raise obvious concerns for both public safety officials and the operators of a very expensive, very visible building.
Sphere and the filmmakers have not released a detailed breakdown of their Las Vegas shoot, but the company's production materials list From The Edge as a 2026 project, filmed with Big Sky cameras and featuring Honnold and other extreme-sports stars. If the viral clip is indeed part of that production, the scene would fit neatly as a planned, camera-driven sequence rather than the work of a lone prankster.
This story will be updated if Sphere or the filmmakers release more information about the climb or confirm who was on top of the dome.
