On the issue dated July 9, 2011, "Moves like Jagger" debuted at number eight on the United States "Billboard" Hot 100, and topped the "Billboard" Hot 100, in the week ending September 10, 2011, as the greatest airplay gainer for the third consecutive week.
It spent 10 weeks in the top 3.
For Maroon 5, with prior top hits, this is the first time at the number-one position on the Hot 100 chart since their single "Makes Me Wonder" in 2007.
For Aguilera, this is her fifth number-one position, her first since "Lady Marmalade" in 2001.
Incidentally, Levine is the first artist to achieve both the number one position on the Hot 100 as a member of a band and reach the top 10 as a solo artist in the same week.
"Moves like Jagger" made Aguilera the fourth female artist, behind Madonna and Janet Jackson (1980s, 1990s, and 2000s) and Britney Spears (1990s, 2000s, and 2010s), to top the Hot 100 in three decades, as well as the eighth artist overall.

On October 5, 2011, the song reached number one in the mid-week chart update but failed to reach the number one spot the following Sunday due to the mid-week release of Rihanna's new single "We Found Love" which debuted at number one keeping "Moves like Jagger" away from the number one position.
Uniquely, in the first six of these weeks it was held off the top of the chart by six different number one singles consecutively, each of which debuted directly ahead of it; this after having already been held at number three behind two different pairs of new entries in its first two weeks on the chart.
