The group also notches the highest-charting debut album by an all-male K-pop group on the Billboard 200.

South Korean K-pop quintet Tomorrow X Together debuts at No. 1 on Billboard’s Emerging Artists chart (dated March 16), becoming the top emerging act in the U.S. for the first time.

The Emerging Artists chart ranks the most popular developing artists of the week, using the same formula as the all-encompassing Billboard Artist 100, which measures artist activity across multiple Billboard charts, including the Hot 100, Billboard 200 and the Social 50. (The Artist 100 lists the most popular acts, overall, each week.) However, the Emerging Artists chart excludes acts that have notched a top 25 entry on either the Hot 100 or Billboard 200, as well as artists that have achieved two or more top 10s on Billboard's "Hot" song genre charts and/or consumption-based "Top" album genre rankings.

Tomorrow X Together’s debut is powered by its debut EP The Dream Chapter: Star, which launches at No. 140 on the Billboard 200 with 7,000 equivalent album units earned in the U.S. in the week ending March 7, according to Nielsen Music. Of its opening week sum, 4,000 were in traditional album sales, enabling the set to concurrently bow on the following album sales-based charts: World Albums (No. 1), Heatseekers Albums (No. 2) and Top Album Sales (No. 26).

Further, on the Billboard 200, The Dream Chapter: Star becomes the highest charting debut album by an all-male K-pop group on the Billboard 200.

The EP becomes the first non-BTS album to lead the World Albums chart since EXO’s EXO 5: Don’t Mess Up My Tempo in November. BTS led the chart for 15 consecutive weeks since then.

The EP’s tracks also make a dent on the World Digital Song Sales chart. “Crown” leads the way at No. 1, followed by “Blue Orangeade” at No. 10, “Cat & Dog” at No. 14 and “Our Summer” at No. 17.

TXT (as their name is often abbreviated) becomes the fourth K-pop group to lead the Emerging Artists chart, and the first since NCT 127 in December. Prior to NCT 127, NCT and BLACPINK each led the ranking for one week each. TXT also becomes just the fifth act to debut at No. 1 on the Emerging Artists chart, joining PVRIS in 2017, and Anderson East, Sheku Kanneh-Mason and BLACKPINK in 2018.

The group, consisting of Yeonjun, Soobin, Beomgyu, Taehyun and Huening Kai, is signed to Big Hit Entertainment, the same label as BTS.
