150,000 attendees at Sónar 2026. This is the data provided by the festival's management. It is a global figure that also includes Sónar Kids (1,500 people), Sónar+D (4,000), Sónar District parties at Parc del Fòrum, and OffSónar at Poble Espanyol. However, the festival does not detail the audience for OffSónar activities, nor for Sónar District, nor for the three musical days at the Fira Gran Via venue. Therefore, it is difficult to compare it with 2025, beyond the fact that last year the global figure was 161,000 attendees: 52,000 at Sónar de Dia in Montjuïc, 66,500 at the two days of Sónar de Nit in L'Hospitalet de Llobregat, and 42,000 at OffSónar.

British band The Prodigy is the main new addition to the lineup for Sónar 2026, the first edition to be held in a single venue: the Gran Via Fairgrounds in Hospitalet de Llobregat, on June 18, 19, and 20. Another significant change is the separation of Sónar+D, the professional trade fair and congress, which is moving to the Lonja de Mar after sharing space with Sónar by Day performances at the Montjuïc Fairgrounds since 2013. The ongoing construction at the Montjuïc fairgrounds has forced the festival to adjust its daytime and nighttime programming: concerts will be spread across six stages, three outdoors and three indoors. This consolidation of the program also affects the opening hours: the venue will open at 5:00 PM (Sónar by Day already started at midday at Montjuïc).
