It was released on July 6, 2022 by Sony Music Latin and Hollywood Records as the seventh single from Tini's fourth studio album, Cupido (2023).

The song was written by the three singers alongside Elena Rose, while Andrés Torres and Mauricio Rengifo handled musical composition and production.

"La Loto" is a primary bass-heavy reggaetón party track, with some urbano and modern hip hop influence.

[3] In an interview, Tini said about the collaboration: “The truth is that both of them have been great references throughout my musical growth, as women in the industry and as artists, I have to say that I have always dreamt of doing something with one of them.

Instead of trying to make headlines about who is fighting about what, it's about our record-breaking numbers.”[5] On June 27, Tini announced via her social media, that a song was coming with the Brazilian and American singers.

[6] "La Loto" was written by Tini, Becky G, Anitta, and Elena Rose; Andrés Torres and Mauricio "El Dandee" Rengifo composed and produced the song.

Anitta takes the second verse: "I fly directly from Miami to Rio [...] I brought Tini, we're gonna make a tremendous mess" before stating "Diamonds shining from head to toe/ The one that's with me won the lotto".

The line "The baby with me won the lotto" expresses female empowerment, with the girls alluding to being the biggest and best prize their partners could have.

[12] Rather than the typically-modern nightclub scenes of many music videos, “La Loto” takes place in a 1920s-style “speakeasy” setting, with rather dark, subdued lighting, along with jewels, diamonds and gold elements.

Next, Tini is entering a crowded bar, in a jewel-studded black catsuit and stilettos, wearing gold sunglasses and a large, pink faux-fur coat.

Then, Becky G is seen sitting on a sofa, in an all-black ensemble, surrounded by opulent pearls and vintage jewelry, with the male dancers wearing masquerade ball masks.
