The semi-final took place in Basel’s St Jakobshalle, where ten acts qualified for the upcoming grand finale, highlighting Sweden's KAJ as a strong contender with their comedic sauna anthem.

Dion, who captured the Eurovision crown in 1988, expressed her heartfelt connection with Switzerland, stating, "Switzerland will forever hold a special place in my heart." Although unable to attend in person due to health challenges related to her ongoing battle with stiff-person syndrome, her spirit echoed through the event.

During the semi-finals, a diverse array of performances enchanted the audience. KAJ, an acrostic group from Finland, led the charge with their infectious rhythm in "Bara Bada Bastu," which means "let's take a sauna." According to bookmakers, their chances of winning are significant, potentially marking Sweden’s eighth Eurovision triumph, a record in the contest's history.

Among the other impressive acts were Poland's Justyna Steczkowska, who wowed with an aerial performance, and Ukraine’s Ziferblat, delivering a poignant anthem reflecting their experiences amid ongoing conflict. Despite strong competition, KAJ's playful anthem captivated the audience, cementing their status as the favorites to win.

The night, full of emotional performances and nostalgic tributes, showcased the resilience and creativity that the Eurovision Song Contest fosters. As excitement builds for the grand finale, organizers remain hopeful that Dion may still make a surprise appearance to amplify the celebrations.
