The 2025 edition of TIC Domicílios survey shows a rise in online betting behaviour among Brazilians, with 19% of all internet users reporting that they engaged in some form of online gambling in the three months prior to the survey.
The study, published by the Regional Center for Studies on the Development of the Information Society, also found that 85% of the national population accessed the internet during the year, the equivalent of 157 million people.
Among those who said they had placed a bet, men accounted for 25% and women for 14%, which was also calculated by another survey that has shown that among active bettors in the country, the prevalence is male.
The data also breaks down the types of gambling accessed: 8% of Brazilians participated in online casinos, 7% paid to enter digital raffles or draws, 7% placed sports bets through websites or apps and 7% bought federal lottery tickets online.
The gender gap was most pronounced in sports betting, where 12% of male users had wagered compared with just 2% of female users.
The findings prompted a warning from the Brazilian Internet Steering Committee (CGI.br).
"What we see is a very alarming number: we have around 30 million people over the age of 10 who have already placed some type of online bet," stated Renata Mielli, Coordinator of CGI.br.
She added that the data reinforces the need for regulatory mechanisms and stronger digital education on the risks associated with online gambling.
The survey also provides insight into broader digital behaviour in the country. Internet access is now present in 85% of households, compared to 51% a decade ago.
Still, an estimated 28 million Brazilians remain offline, most of them older citizens and people with lower levels of formal education.
