The inclusion of Israel among the participants in the context of the Gaza war was met with controversy, and additional security measures were put in place for the event.

The winner was Switzerland with the song "The Code", performed by the Swiss singer Nemo and written by them with Benjamin Alasu, Lasse Midtsian Nymann, and Linda Dale.

[6][9] Planned street music performances were affected by the withdrawal of several artists due to Israel's participation in the contest and were ultimately transferred to the Eurovision Village for security reasons.

[15] After Sweden's win in the 2023 contest, the municipalities of Stockholm, Gothenburg, Malmö, Eskilstuna, Jönköping, Örnsköldsvik, Partille and Sandviken expressed interest in hosting the 2024 edition.

Designed by Stockholm-based agencies Uncut and Bold Scandinavia, it was based on simple, linear gradients inspired by vertical lines found on auroras and sound equalisers, and was built with adaptability across different formats taken into account.

The stage featured five movable LED cubes, floors and a backdrop screen along with other lighting, video and stagecraft technology, all set around a cross-shaped centre, with the aim of "creating a unique 360-degree experience" for viewers.

Mede had previously hosted both the 2013 and 2016 editions (solo and with Måns Zelmerlöw, respectively), as well as the 2015 special anniversary programme Eurovision Song Contest's Greatest Hits alongside Graham Norton.

[111] The "Turquoise Carpet" and opening ceremony events were hosted by Elecktra and Tia Kofi,[112] while Jovan Radomir moderated the contest's press conferences.

[113] In November 2023, the production team at SVT stated its intention to increase security measures and to keep in contact with Malmö's police authority during the contest, citing a tense climate of protest amid Israel's participation.

[114] This included police reinforcement from Denmark and Norway, tightened cybersecurity, and a no-fly zone to prevent drone attacks,[115][116][117] as well as adjustments to the number of locations set to host side events.

[126][127] After the outcome of the 2023 contest, which saw Sweden win despite Finland's lead in the televoting, sparked controversy among the audience, Norwegian broadcaster NRK began discussions with the EBU regarding a potential revision of the jury voting procedure.

[128] In an interview, the Norwegian head of delegation Stig Karlsen [no] discussed the idea of reducing the jury's weight on the final score, from the current 49.4%, to 40% or 30%.

[132] Following an incident which ultimately led to the disqualification of the Dutch representative, the opening of the "Rest of the World" voting window for the final was delayed until eight hours before the show.

[147] This semi-final was opened by former participants Eleni Foureira, Eric Saade and Chanel, who performed their respective competing songs – "Fuego" (Cyprus 2018), "Popular" (Sweden 2011) and "SloMo" (Spain 2022).

[152] This semi-final was opened by a pre-recorded segment, in which presenters Petra Mede and Malin Åkerman performed the 2023 winning song "Tattoo" with minor lyrical changes.

[153][154] The interval acts included Helena Paparizou, Charlotte Perrelli and Sertab Erener performing their respective winning songs – "My Number One" (Greece 2005), "Take Me to Your Heaven" (Sweden 1999) and "Everyway That I Can" (Turkey 2003) – with the audience taking part in a sing-along;[151] and "We Just Love Eurovision Too Much", a musical number performed by Mede that satirised various aspects of the contest and Sweden's success in the event, with appearances by Perrelli, Sarah Dawn Finer reprising her role as Lynda Woodruff, and 2023 Finnish representative Käärijä performing an excerpt of his competing song "Cha Cha Cha".

[159] Despite qualifying for the final, where it was set to perform in position 5, the Netherlands was disqualified due to a backstage incident between its entrant Joost Klein and a member of the production team.

[162] Switzerland won the contest with the song "The Code", performed by Nemo and written by them along with Benjamin Alasu, Lasse Midtsian Nymann, and Linda Dale.

Croatia came second with 547 points and won the televote, with Ukraine, France, Israel, Ireland, Italy, Armenia, Sweden, and Portugal completing the top ten.

[163][164] The final was opened by Björn Skifs performing "Hooked on a Feeling", followed by the flag parade, introducing all twenty-five finalists, set to a medley of well-known Swedish hits.

[173][174] Following a reprise of their winning song, Nemo broke the trophy,[175][176] although its design had been strengthened after the one presented to Alexander Rybak in 2009 met a similar fate.

[177] The spokespersons announced the 12-point score from their respective country's national jury in the following order:[178] The ten qualifiers from the first semi-final were determined solely by televoting.

After all votes were cast, the top-ranked entry in the 2024 poll was "Rim Tim Tagi Dim" performed by Baby Lasagna; the top five results are shown below.

[361] Before the first semi-final, Ireland's entrant Bambie Thug was asked to replace Ogham-script text written on their body that read 'ceasefire' and 'freedom for Palestine'; they were subsequently changed to 'crown the witch'.

[363][364] During the final, the Portuguese entrant Iolanda wore nail art featuring Palestinian symbols, and said "peace will prevail" at the end of her performance.

"[367] The artists representing Ireland (Bambie Thug), Switzerland (Nemo), and Greece (Marina Satti) were all absent from the flag parade of the third dress rehearsal for the final, held the afternoon before the live show.

[366] According to a report by Norwegian newspaper VG, Greece, Ireland, Norway, Portugal, Switzerland, and the United Kingdom all considered withdrawing from the final, before reaching an agreement with the EBU 25 minutes prior to the start of the show;[371][372] Greek broadcaster ERT, head of the Swiss delegation Yves Schifferle, and Iolanda's management agency denied that the delegations were considering withdrawal, with Schifferle confirming that Nemo themself led the talks with the EBU on behalf of the artists concerned.

[379] The EBU commissioned an independent investigation into the complaints regarding the working atmosphere during the event,[380] and on 1 July 2024, it announced a number of organisational changes.

[381] Among these are the creation of a "ESC director" role to oversee the work of executive supervisor Martin Österdahl and the head of brand and commercial, and recommendations for the appointment of a welfare producer and a crisis management team.

[386] A video posted to social media showed audio of the applause track cutting out and replaying during the announcement of the Dutch jury points.
