Bad Bunny explained how the creative process of the song was different than his previous works: "I usually have a main idea for a song. For this one, though, Jhay composed the base, the initial rhythm and the main idea together with Mora. I then added to the evolution of the production, rhythm and lyrics with Tainy. It was a combined effort, which is unusual for me, but when one works as a team, great things come out".

"Dakiti" is a "slow-burning", "futuristic" reggaeton song with "wavy" electronic sounds backing the production. It contains an edgy synth riff, "lush" ambience, as well as heavier, thumping beats, and, as noted by ¡Hola!'s Rebecah Jacobs, is "a departure from the more aggressive reggaetón celebrations we're used to hearing from Bad Bunny on his 2020 releases, YHLQMDLG and Las que no iban a salir. Lyrically, the song sees the artists aiming to win over their love interests by flaunting their luxurious lifestyles. The title of the song has been speculated to refer to either the name of a beach or possibly an old bar in Puerto Rico.

The song's release was accompanied by an "aquatic" music video directed by Stillz, who worked on some of Bad Bunny's previous visuals, including "Yo Perreo Sola". The video sees Bad Bunny and Cortez performing the song in an isolated floating box in the middle of the ocean. They also party underwater, on a boat and pilot their own submarines. Bad Bunny sports braided curls and a skirt, with Cortez wearing jewelry by Ian Delucca. The video concludes with a big truck driving by with a message that reads: :El Último Tour Del Mundo" ("The Last Tour of the World").

The song debuted at number nine on the US Billboard Hot 100. It became Bad Bunny's third Hot 100 top 10, following "I Like It", his collaboration with Cardi B and J Balvin, and "Mia", featuring Drake, both in 2018. "Dakiti" also joined "Mia" as the only all-Spanish-language songs to have ever debuted in the Hot 100's top 10. The song marked Cortez's first top 10 on the chart. It reached number five in its fifth charting week.

It also debuted at number one on the Hot Latin Songs chart, marking the first time a song debuted in the Hot 100 top 10 and atop Hot Latin Songs simultaneously. It became the third song in 2020 to debut at number one on the latter chart; the previous two debuts also belong to Bad Bunny ("Si Veo a Tu Mamá" and "Un Día (One Day)"). The song earned the biggest streaming week for a Latin song, garnering 22.2 million streams, besting Bad Bunny's own "Si Veo a Tu Mamá", which accumulated 19 million streams in March 2020.

"Dakiti" topped the Billboard Global 200 chart for two weeks. It became the first song to earn 100 million streams two weeks in a row on the chart. It also became the first Spanish-language song to top both the Global 200 and the Global Excl. U.S. 200, doing so simultaneously.

Bad Bunny said of the song's success, "This one is very special because it's a song that came out of nothing. We didn't expect to have success of this magnitude. Working with Jhay, both Latinos from Puerto Rico representing at a global level, fills me with pride as we are competing amongst great songs and artists".
