Beneath electrifying Tesla coil disco balls, Marshmello ascended the glowing 360-degree rotating DJ booth shaped like his signature cylindrical mask. His headpiece immediately illuminated in rainbow, mimicking the multi-colored laser beams and special effects scattered throughout the 29,000-square-foot nightclub. 

This scene last April kicked off Marshmello’s residency at the new Kaos Dayclub and Nightclub at the Palms Casino Resort in Las Vegas, part of a megadeal worth $60 million. 

Even with that massive haul, Marshmello isn’t the highest-paid electronic act in the world—that honor goes to the Chainsmokers, who garnered $46 million in pretax income over the past year. The duo of Drew Taggart and Alex Pall top our annual Electronic Cash Kings list with their biggest earnings year yet, dethroning Calvin Harris after six consecutive years at No. 1.

Over the past year, the Chainsmokers performed at the XS Nightclub and Encore Beach Club as part of a three-year residency with Wynn Nightlife announced in 2017 (and recently extended until 2021). In between Vegas gigs, the duo played a multitude of festivals and private shows, pulling in mid six-figure sums per night. Their yearly total also factors in endorsements and recorded music sales.
