A Nevada judge has handed down a 45-day jail sentence to a man who calls himself the “pro-life Spiderman,” following his daring climb of the Las Vegas Sphere. This stunt, which authorities report resulted in tens of thousands of dollars in damages, also led to a suspended sentence and probation for the individual, according to court documents.
Mason Des Champs, aged 26, received his sentence on Monday. He was given a 364-day jail term, with all but 45 days suspended, along with a year of probation after he admitted guilt to a gross misdemeanor. The charge was for acting with willful or wanton disregard for the safety of individuals or property, as detailed in the court records.
Currently detained, Des Champs is anticipated to be released around June 4, 2026, based on information from jail records.
In addition to his sentence, he has been ordered to compensate Sphere Entertainment Company with a restitution payment of $77,270.32.

The Sphere sustained about $100,000 in damage during the February 2024 stunt, according to local outlet FOX5 Vegas.
Des Champs climbed the exterior of the 366-foot Las Vegas landmark on Feb. 7, 2024, livestreaming the stunt as part of a fundraising effort tied to his anti-abortion activism, according to reports.
The climber said the effort was intended to support a pregnant woman he identified as “Isabel,” according to a fundraiser he launched through the nonprofit Let Them Live.
“Our mission is twofold: to offer Isabel the tangible support she desperately needs and to rally a community around her,” Des Champs wrote on the fundraising page.

The fundraiser ultimately raised more than $47,000, according to the page, which described the woman as homeless and facing an abortion scheduled days after the climb.
Des Champs has carried out similar high-profile climbs in recent years, often tying the stunts to fundraising efforts for expectant mothers. In 2023, he scaled the 40-story Chase Tower in Phoenix to raise money for a pregnant woman in need, telling Fox News at the time he wanted to show “how to have faith over fear.”

He also climbed a 42-story skyscraper in Chicago later that year, livestreaming the stunt as part of a campaign to raise money for another expectant mother, according to prior Fox News reporting.
Des Champs pleaded guilty in October 2025 in connection with the Las Vegas incident, court records show.
The case was closed following his sentencing on April 20.
