Critical Writing for
Pitchfork, Nina Corcoran wrote that Mars "delivers the type of chart-topping boogie that's quintessentially him". Pavel Snapkou of
Showbiz by PS noted that while the single draws heavily on familiar elements from Mars's past eras, it remains smooth, catchy, and radio-friendly, lyrically inept, even if it does not radically reinvent his sound.
Commercial "I Just Might" received 13.73 million on-demand streams in the United States during its first four days of availability. "I Just Might" debuted at number one on the US
Billboard Hot 100, becoming his first song to do so. On its first release week, the single debuted with 23.5 million streams, 32.6 million radio airplay, and sold 13,000 copies in the United States. It became Mars's fourth number one on the Streaming Songs chart and twelfth number one on Digital Song Sales and the singer's personal best on Radio Songs (number 12) and the highest start for a lead male artist since the charts' inception in 1998. The song also became its fifth number one on
Hot R&B/Hip-Hop Songs. He also tied Drake, Michael Jackson, and Stevie Wonder as the only solo male with 10 or more number-one songs on the
Billboard Hot 100. Mars is also one of the artists with the most cumulative weeks at number one, with 40. "I Just Might" spent a second week on the top of the
Billboard Hot 100. The single had 17.1 million streams, 40.8 million radio airplay, and sold 9,000 copies in the United States. The song reached the top ten of Radio Songs, entering at number nine, becoming Mars's 21st top 10; and a second week as the most sold track on Digital Song Sales. Mars topped the Hot 100 for at least two weeks with eight of his 10 career number one songs. He becomes the best among males and ties Janet Jackson for second-best, after Mariah Carey's. "I Just Might" rose to number one on the Hot 100 once again in March for a third week, with 18 million streams, 72.5 million radio airplay, and 6,000 copies sold in the United States. In the United States, Mars's catalog (except "I Just Might") received a 75 percent rise when compared to the previous week, as it was streamed 50.87 million times during the first four days of the aforementioned single availability. "I Just Might" became his eleventh song to reach the top ten of the
Billboard Adult R&B Songs chart, peaking at number three. When "I Just Might" topped the
Billboard Pop Airplay, Mars became the first male act to have twelve number one songs on the aforementioned chart. So far, Mars has topped the
Hot R&B/Hip-Hop Songs for fifteen weeks, extending his longest career top on the chart. The ten weeks spent on the top of
Radio Songs tied with "
Leave the Door Open" by his american musical superduo
Silk Sonic with
Anderson .Paak.
