Jackpot received generally mixed reviews from music critics who drew comparisons to fellow St. Louis rapper Nelly. Roni Sarig of Rolling Stone praised the album for its mixture of different U.S. regions from hip-hop concluding with "Taken all together, Jackpot is short on depth, but it's a ride with some hitworthy moments and plenty of bounce." Steve 'Flash' Juon of RapReviews was mixed about the album, being ambivalent towards the Trak Starz's production and Chingy's skills as a rapper, saying "As a summer album, Chingy's "Jackpot" is a take it or leave it affair. It's relatively inoffensive, and certainly has some songs you'd want to play at a party, club or while driving around." Dorian Lynskey of The Guardian also saw the album's tropes and Chingy's use of Nelly's style.
Jason Birchmeier of AllMusic was also mixed towards the album, finding the song's hooks not being on par with the beats and Chingy himself lacking in substance in his rhymes. Joe Caramanica of Entertainment Weekly felt that Chingy paled in comparison to Nelly, despite having the same vocal tic as him saying "Chingy has only one gimmick, and while it charms on "Sample Dat Ass" and "One Call Away," most of Jackpot is as ephemeral as the winds blowing through the Arch."Robert Christgau rated the album as a "choice cut", singling out "Chingy Jackpot" as a standout track. Dom Passantino of Stylus Magazine gave a negative review, criticizing the production for having weak beats and found every other track "a failed second single." He also called out other critics' reviews for their so-called criticism of the album.
The album entered the Billboard 200 at number 2 with first week sales of 157,000 copies in the US. It has currently[when?] sold 2.8 million copies in the US and is certified double platinum by the RIAA.
