Brazil's decision to prohibit fixed-odds betting and online casino operations has been followed by a rapid increase in newly identified illegal gambling websites.
According to monitoring data reported by Bet Legal, 428 new illegal betting sites appeared between September 25 and September 27, 2026, immediately following the announcement of Provisional Measure No. 1,394/2026.
The figures highlight one of the central challenges facing Brazilian authorities as the country moves from a regulated online betting market toward prohibition: preventing players from migrating to offshore and unlicensed operators. BNLData
Illegal betting sites multiply after Brazil's ban
The increase was particularly sharp following the government's announcement.
Bet Legal reportedly identified 674 new illegal betting domains between September 21 and September 27. Of these, 246 appeared between September 21 and 24, while another 428 appeared during the three days from September 25 to 27.
That represents approximately 143 newly detected illegal sites per day during the latter period.
For comparison, industry data cited by BNLData indicated that the Brazilian Association of Games and Lotteries (ANJL) had previously recorded an average of approximately 13.7 new illegal domains per day between June and August.
This does not necessarily mean that all 428 websites attracted significant numbers of Brazilian players. The figure refers to newly identified illegal betting sites and should therefore be interpreted as an indicator of the expansion of unlicensed supply rather than direct evidence of player migration.
Brazil orders thousands of betting domains blocked
The scale of Brazil's enforcement operation is considerably larger than the 428 newly identified domains.
On September 29, Brazil's Ministry of Justice and Public Security and Ministry of Finance announced that they had requested the blocking of 5,209 domains associated with illegal betting activity.
Of those, 1,386 were identified by the National Secretariat for Digital Rights, while another 3,823 were submitted by the Ministry of Finance's Secretariat of Prizes and Betting.

Authorities are also targeting the distribution and promotion infrastructure surrounding illegal gambling. The government said it had requested the removal of hundreds of social-media pages and profiles associated with betting promotion, while 186 betting applications were also notified for removal from app stores.

What changed in Brazil?
Brazil had only recently completed the transition to a federally regulated betting market.
The regulated system officially launched in January 2025 after the country established licensing, taxation, technical standards and responsible-gambling requirements for operators.
That framework was fundamentally changed on September 25, 2026, when Provisional Measure No. 1,394/2026 prohibited the exploitation, offering, intermediation and advertising of fixed-odds betting lotteries in Brazil. Serviços e Informações do Brasil
The measure therefore affects both sports betting and the online gaming operations that had been permitted under the regulated framework.
The prohibition has also created a major enforcement challenge. Licensed operators can be ordered to cease operations, but offshore gambling websites can potentially reappear under new domains after existing addresses are blocked.
Black-market concerns grow
The emergence of hundreds of new domains has intensified the debate over whether prohibition will reduce gambling activity or redirect part of the market toward unlicensed operators.
Industry representatives argue that regulated platforms had been required to implement consumer-protection measures that illegal operators can ignore. These include identity verification, restrictions on minors, responsible-gambling controls and other compliance requirements.
That argument should be treated separately from the question of whether prohibition reduces gambling harm overall. Supporters of tighter restrictions point to the social and public-health costs associated with widespread online gambling, while opponents of prohibition emphasize the difficulty of preventing access to offshore operators.
The first days following the measure provide evidence that illegal supply can expand quickly. They do not, by themselves, establish how many Brazilian bettors will ultimately migrate to those platforms.
Enforcement becomes the next major test
Brazilian authorities are responding with a coordinated campaign involving the Ministry of Justice, Ministry of Finance and Anatel.
The government's strategy extends beyond simply blocking websites. Authorities are also targeting advertising, social-media promotion, mobile applications and financial channels used by unauthorized operators.
The Ministry of Justice said enforcement would be permanent and continuous, rather than a one-time blocking operation. Serviços e Informações do Brasil
That distinction is important because domain blocking alone presents a technical limitation: operators can register replacement domains and redirect users to new addresses.
As a result, the effectiveness of Brazil's betting ban will depend heavily on whether authorities can disrupt the wider infrastructure supporting illegal operators, particularly payments, advertising and customer acquisition.
What happens next?
Provisional Measure No. 1,394/2026 took effect immediately, but as a provisional measure it requires congressional action to remain in force over the longer term.
Meanwhile, Brazil is moving rapidly to dismantle the infrastructure of the previously regulated betting market and restrict access to unauthorized alternatives.
The early numbers demonstrate the scale of that challenge.
428 newly detected illegal betting sites in three days is significant, but the broader government enforcement figures are even larger: 5,209 domains had already been submitted for blocking by September 29. BNLData
For Brazil, the next phase of the gambling-policy shift will therefore be determined not only by legislation, but by how effectively regulators, telecom providers, payment companies, app stores and online platforms can restrict access to the expanding illegal market.
