Eminem performs onstage at the 2014 MTV Movie Awards at Nokia Theatre L.A. Live on April 13, 2014 in Los Angeles.

Plus, G-Eazy hits a new peak at No. 6.

Eminem leaps from No. 37 to No. 1 on the Billboard Artist 100 chart (dated Jan. 3) to become the top musical act in the U.S. for the first time.

The Artist 100, which launched in July 2014, measures artist activity across key metrics of music consumption, blending album and track sales, radio airplay, streaming and social media fan interaction to provide a weekly multi-dimensional ranking of artist popularity.

Eminem's reign is powered by his ninth studio album, Revival, which debuts at No. 1 on the Billboard 200 with 267,000 equivalent album units, according to Nielsen Music. The entrance makes Eminem the first artist to debut eight consecutive titles at No. 1 in the all-genre album chart's history.

Eminem's rise to No. 1 also ends a drought among rappers atop the Artist 100. Four solo rappers crowned the chart in 2017, with JAY-Z being the most recent on the Aug. 5-dated ranking. Kendrick Lamar, Drake and Future also hit No. 1 in 2017.

Album sales contribute the majority of Eminem's Artist 100 points (60 percent), followed by digital song sales (20 percent).

On the Billboard Hot 100, Eminem charts three songs from Revival: "River," featuring Ed Sheeran, debuts at No. 11; "Walk on Water," featuring Beyoncé, re-enters at No. 87 (after previously peaking at No. 14); and "Believe" enters at No. 92.

Rounding out the Artist 100's top five, Sheeran dips to No. 2 after six (nonconsecutive) weeks at No. 1; Taylor Swift falls 2-3; Post Malone rises 5-4; and Pentatonix drops 3-5.

Among other Artist 100 moves, G-Eazy hits a new peak, vaulting 34-6, as his The Beautiful & Damned arrives at No. 3 on the Billboard 200 with 122,000 equivalent album units.
