"Qami" performed by Sevak Khanagyan was selected as the winner following the combination of votes from an international jury and a public televote.

[3] Armenia has used various methods to select the Armenian entry in the past, such as a live televised national final to choose the performer, song or both to compete at Eurovision.

However, AMPTV announced along with their participation confirmation that Depi Evratesil would once again be organized but would select both the artist and the song for the 2018 contest.

[7] Among the competing artists was Tamar Kaprelian who represented Armenia in the Eurovision Song Contest 2015 as part of the group Genealogy.

In addition to the performances of the competing entries, the interval act featured Armenian 2017 Eurovision entrant Artsvik with "Fly with Me" and "No Fear".

Sevak Khanagyan filmed the official video for "Qami" following his win at Depi Evratesil 2018, which was directed by Arthur Manukyan and featured fashion designs by Aram Nikolyan.

[6][11] Sevak Khanagyan made several appearances across Europe to specifically promote "Qami" as the Armenian Eurovision entry.

On 7 April, Sevak Khanagyan performed during the Eurovision Pre-Party, which was held at the VEGAS Kuntsevo shopping mall in Moscow, Russia.

[13] On 14 April, Khanagyan performed during the Eurovision in Concert event which was held at the AFAS Live venue in Amsterdam, Netherlands and hosted by Edsilia Rombley and Cornald Maas.

[14] Khanagyan also performed during the ESPreParty event on 21 April which was held at the Sala La Riviera venue in Madrid, Spain and hosted by Soraya Arnelas.

[16] On 29 January 2018, a special allocation draw was held which placed each country into one of the two semi-finals, as well as which half of the show they would perform in.

Each nation's jury consisted of five music industry professionals who are citizens of the country they represent, with their names published before the contest to ensure transparency.

This jury judged each entry based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.

The individual rankings of each jury member as well as the nation's televoting results were released shortly after the grand final.
