Third Annual “Sphere XO Student Design Challenge” Launches With Pi Day Theme

More than 100,000 Clark County-Based Students Have the Opportunity to Design Artwork Inspired by the Infinite Possibilities of Pi for Sphere's Exosphere - the World's Largest LED Screen

Winners Will Be Revealed on March 11 Ahead of Pi Day

LAS VEGAS (October 22, 2025) - Sphere Entertainment Co. (NYSE: SPHR) announced today the return of the Sphere XO Student Design Challenge and this year's theme: Pi Day. More than 100,000 Clark County-based students will again be invited to create art for the Exosphere as part of the annual collaboration between Sphere, the Clark County School District (CCSD) and University of Nevada, Las Vegas (UNLV). The winning students' art will debut on the Exosphere on Wednesday, March 11, 2026, just ahead of Pi Day which is celebrated annually on March 14.

At Sphere, nearly every mathematical equation that was used in the venue's creation and construction involves Pi, a mathematical constant (3.14159…) that represents the ratio of a circle's circumference to its diameter. Pi Day offers an opportunity for student artists to think creatively about the intersection of art and science - the same principles that inspired and built Sphere. The Pi Day theme follows previous years' challenges, which were centered around Earth Day and Fourth of July.

"We're proud to partner once again with the Clark County School District and UNLV for this year's Pi Day-themed challenge, celebrating the power of art and science to inspire curiosity and wonder," said Rich Constable, Executive Vice President, Global Head of Government Affairs & Social Impact, Sphere. "Creativity, like Pi itself, has no bounds, and we can't wait to see how these talented students bring that spirit to life on the world's largest LED screen."

"This is an amazing opportunity for CCSD students to showcase their artistic talents and creativity on the world's most unique canvas," said CCSD Superintendent Jhone Ebert. "The District is proud to continue its partnership with Sphere to bring out the passion and artistry from within our students. As a former math teacher, I look forward to seeing the creative ways students will celebrate Pi Day."

"The UNLV College of Fine Arts is extremely pleased and excited to continue our XO Student Design Challenge partnership with Sphere, with the 2026 theme of Pi Day. This endeavor is a particularly powerful educational opportunity for students, in that it is rooted in the integration of arts, technology, and science, and is broadly conceived to include all stages of education - from elementary through university graduate school. This incredibly innovative and visionary project is truly unique in the global context," said Dr. Nancy J. Uscher, Dean, College of Fine Arts, UNLV.

The Sphere XO Student Design Challenge is open to more than 100,000 Clark County-based students from elementary school through college, who will have the opportunity to have their artwork displayed on the Exosphere. Winners will be selected by a combination of public voting and a panel of judges, and their work will be unveiled on March 11, 2026 at a community celebration at Sphere just ahead of Pi Day.

Additionally, winning CCSD high school and UNLV students will receive a $10,000 educational scholarship from Sphere. Winning CCSD elementary and middle school students will earn a $10,000 donation from Sphere for their school's art program to further art education in public schools, along with tickets for their entire school to attend The Wizard of Oz at Sphere.

The Exosphere, which at 580,000 square feet is the world's largest digital canvas, is recognized worldwide for its impactful visuals. The Exosphere consists of approximately 1.2 million LED pucks, spaced eight inches apart. Each puck contains 48 individual LED diodes, with each diode capable of displaying more than 1 billion different colors - creating a vivid landmark on the Las Vegas skyline.
