The Backstreet Boys are having a blast during their residency at the Sphere in Las Vegas - and apparently raking in the cash as well. According to a Thursday, August 28, report from TMZ, the boy band is grossing $4 million per night for each show held at the Sin City venue. The outlet notes that costs are somewhat lower for a residency than a traditional tour, as the group doesn't have to factor in so many travel costs when they're staying in one location. Additionally, the outlet reported that BSB paid a one-time fee of about $7 to $8 million for the graphics used in the show, but they quickly recouped the investment with profits from platinum and VIP packages sold to fans. The Backstreet Boys - made up of Kevin Richardson, AJ McLean, Howie Dorough, Brian Littrell and Nick Carter - kicked off their Sphere residency on July 11 and performed select dates throughout the month before returning in August. They are set to play several more dates at the Sphere from December 26 through January 3, 2026, followed by seven more shows in February 2026.

The beginning of the group's Sphere residency coincided with the release of Millennium 2.0, celebrating the 25th anniversary of their second U.S. studio album, Millennium. The new edition featured 13 bonus tracks, including live recordings and demos from that era. After the residency kicked off last month, Carter, 45, admitted that he was overwhelmed by the significance of the moment. BTS! 1D! 'NSync!

"We've been together so long and had so many ups and downs, so the fact we can still perform on any stage is amazing." McLean, 47, admitted in a separate interview that Millennium isn't his favorite BSB album, but he was still thrilled about putting on the show. "What I'm excited about with this whole experience is that we're making another memory together," he told the Los Angeles Times in July. "We've told everyone coming to wear white, and it sounds like everyone's gonna do it. It's gonna be incredible to look out at a sea of white and sparkles and all the things from 1999."
