Coldplay are reportedly on track to set new records with their 225-date Music of the Spheres world tour, with industry estimates indicating the run could sell more than 13 million tickets and generate roughly £1 billion in ticket revenue.

Concert-data company Pollstar's chief, Andy Gensler, told the Daily Mail that cumulative grosses for the tour had already reached about $1.39 billion and that the London dates should push the total past $1.4 billion. Final figures, he said, would not be confirmed until after the band's remaining shows at Wembley Stadium conclude. The reported ticket revenue would make Coldplay the highest-earning live performers in UK history, eclipsing the roughly £718 million taken by Sir Elton John's Farewell Yellow Brick Road tour, according to the report.

The tour's commercial success has coincided with several high-profile incidents at recent shows that have drawn media attention and public reaction. At a Wembley Stadium performance, frontman Chris Martin brought two fans on stage who identified themselves as being from Israel; footage of the exchange shows the pair were booed by parts of the crowd. Martin told the audience he considered everyone "equal humans on Earth regardless of where you come from," and he acknowledged Palestinian fans in the venue, which drew cheers.

After the Wembley appearance, one of the two fans told Israeli broadcaster Kan that she had briefly considered not revealing her nationality. Pro-Israel commentators criticized Martin for what they described as a failure to more forcefully defend the fans from the boos; Israeli-American technology commentator Yaron Samid, identifying himself as a "proud Zionist," wrote that he and his wife felt hurt by Martin's handling of the moment. The Macabee Task Force, which describes its mission as addressing anti-Semitism and anti-Zionism on U.S. campuses, publicly faulted the band for lacking what it called a "backbone."

Others at the shows and viewers online praised Martin's remarks. Some attendees said he handled the situation with class and that his message of equal humanity was appropriate amid tensions surrounding the Israel-Hamas conflict. Later in the Wembley set, Martin performed a duet with Palestinian-Chilean singer Elyanna on the song "We Pray," which features an Arabic verse. Elyanna has postponed parts of a U.S. tour since the outbreak of fighting in Gaza and has sold merchandise pledging support for Palestinian causes, the Daily Mail reported.

Weeks earlier in July, a separate incident at a Foxborough, Massachusetts, concert drew widespread attention when a stadium "kiss cam" moment appeared to reveal an extramarital relationship between two attendees identified in media reports as Astronomer CEO Andy Byron and the company's head of human resources, Kristin Cabot. The pair were seen in an embrace on stadium screens and later resigned from their positions after the episode attracted online attention and media scrutiny, the report said.

Despite the controversies, promoters and industry watchers continue to point to the tour's extraordinary commercial performance. Reports suggest merchandise sales, sponsorship and other ancillary revenue could increase the tour's haul beyond the reported £1 billion in ticket receipts. Pollstar's figures and the Daily Mail coverage indicate the Music of the Spheres tour has become one of the highest-grossing concert runs in modern live-music history.

Representatives for Coldplay and for Chris Martin did not provide immediate comment in the reports summarizing the Wembley exchange and other incidents. The band continues to perform dates as part of the global tour, which has drawn large stadium audiences and sustained attention in international media for both its box-office success and the moments of controversy that have arisen at certain shows.
