"Butterfly Effect" (stylized in all caps) is a song by American rapper Travis Scott.

During a performance in Portsmouth, Virginia on May 4, 2017, Scott hinted at the release of new music in a freestyle.

[2][3] Lawrence Burney of Vice magazine said: "'Butterfly Effect' is textbook slurred Scott number, with backing vocals that sounds eerily similar to Migos' 'Slippery.

[5] Similarly, Tom Breihan of Stereogum said: "'Butterfly Effect' is low-key and melodic, with some sharp production from Drake collaborator Murda Beatz.

[11] Scott also performed the song at the MTV Europe Music Awards on November 12, 2017.
