The Bad Bunny concert residency in Puerto Rico consisted of 30 shows, attracting roughly half a million people overall. Individual concerts were held at the José Miguel Agrelot Coliseum, with a capacity of about 18,500 spectators per show. The concerts collectively generated an estimated $733 million for Puerto Rico and were partly livestreamed to a global audience. The final concert marked the end of this residency, which was a cultural event for the island and also had a significant economic impact.
So, if the question is about the total number of people attending the full residency, it was about 500,000 people. If it is about a single concert, the venue capacity is approximately 18,500.
