Shares in Hybe, the parent company of South Korean boyband BTS, fell 15% on Monday as their much-anticipated comeback drew a smaller crowd than expected.

Analysts project total tour earnings of as much as $1.8 billion, rivaling Taylor Swift's Eras Tour and Coldplay's Music of the Spheres World Tour.

The concert was attended by an estimated 104,000 fans, much lower than the expected 260,000.
