The self-proclaimed “Pro-life Spiderman” was sentenced to prison for climbing the Las Vegas Sphere and causing $100,000 in damages — after he taunted cops that he would escape conviction.

Professional climber activist Maison Des Champs was ordered Monday to spend 45 days behind bars for climbing the 366-foot attraction on Feb. 7, 2024, according to court records viewed by The Post.

On Monday, a Clark County Judge sentenced Des Champs to a suspended prison sentence of 364 days.

He must also pay $77,270.32 in restitution to the Sphere Entertainment Complex, the James Dolan-run group that oversees the Sphere.

In addition to prison time and his costly fees, Des Champs will serve one year of probation.

Des Champs, 26, had walked across multiple illuminated panels of the orb-shaped entertainment venue as part of an elaborate fundraising stunt so that a homeless woman named Isabel could cancel her “abortion appointment.”

He was initially charged with destroying property greater than $5,000 and conspiracy to destroy private property.

The climber pleaded guilty back in October 2025 to a gross misdemeanor charge of acting with willful or wanton disregard for the safety of people or property.

The Vegas native, then 24, livestreamed himself during his climb, pleading to viewers to donate because “she is homeless and pregnant and needs help.”

The Sphere, covered in 58 million lights, sustained approximately $100,000 from Des Champs viral climb.

Arena officials described the exterior paneling as so fragile that engineers need to work from inside the dome in order to avoid damaging any of the delicate LED screens.

During his arrest, the activist climber told police that he had never been convicted for his stunts and that “his attorneys will get him off this incident as well.”

Des Champs climb raised nearly $48,000 for Isabel through the pro-life non-profit Let Them Live.

The organization said it had reached its goal of $25,000 to give to the woman who had been without reliable housing for months and had scheduled an abortion appointment on Feb. 10, 2024, three days after Des Champs climb.

“Our mission is twofold: to offer Isabel the tangible support she desperately needs and to rally a community around her that believes in the power of hope and action,” Des Champs wrote on the fundraiser. “The climb I’m embarking on today symbolizes more than a physical challenge—it’s a metaphor for the uphill battle Isabel faces every day.”

After the stunt, the expectant mother had canceled her appointment, according to the Society for the Protection of Unborn Children.

Des Champs is expected to be released from jail on June 4.

Days before Des Champs sentencing, acclaimed climber Alex Honnold scaled the Sphere as part of a project titled “From the Edge,” a film set to feature “extreme” athletes.

According to Sphere’s website, the film will be directed by Academy Award winners E. Chai Vasarhelyi and Jimmy Chin. Filming will take place in Jordan, Dubai, Switzerland, the Bahamas, Austin, Las Vegas and Maui using cameras that would be able to display the content on the Sphere.
