The vibrant Carnival atmosphere in São Paulo is marred by a significant issue of theft, particularly cell phones, with almost 20% of reported thefts happening in megablock locations during the festivities. Data collected from the security authority reveal that out of a total of 6,067 theft incidents recorded during the Carnival period in 2025, a substantial 1,145 occurred at megablocks, highlighting a critical area where revelers need to exercise caution.

The megablock events, which attract large crowds and feature popular performances, such as those by Ivete Sangalo, are pivotal to the Carnival experience. However, the influx of attendees increases the risk of theft, prompting the need for greater security measures and awareness among partygoers. The city's estimates suggest that the Carnival festivities could draw in about 16 million people, further emphasizing the challenges city authorities face in ensuring public safety amidst the revelry.

As the city prepares for the upcoming 2026 Carnival, officials are likely to take this data into account to improve safety protocols and possibly increase the presence of law enforcement in high-risk areas. This proactive approach aims not only to protect attendees but also to preserve the celebratory spirit of one of Brazil's most iconic events, ensuring that Carnival remains a joyous occasion while mitigating the risks of crime.
