Brazil’s Illegal Betting Share Is Still Large, but the Slide in H1 2026 Matters

Brazil’s illegal betting market is smaller than it was in the first half of 2025, but the current survey still shows a market large enough to matter. That is the useful reading of the latest iGB report: progress is real, but the regulated market is still sharing the field with players who are not using authorised rails.

The study, titled Sizing and Combating the Illegal Betting Market in Brazil, put the illegal share of online bets at 38% to 44% in H1 2026, down from 41% to 51% in the earlier survey. It also found that 48% of bets were placed on domains ending in something other than .bet.br, 37% used credit cards and 23% used cryptocurrencies. Those payment routes are not accepted in the regulated market.

The direction is better than the number

The headline percentage matters, but the direction matters more. A falling illegal share usually means two things are happening at once: more players are finding the authorised market, and the regulated market is becoming easier to identify. Brazil’s Ministry of Finance says that, since 1 January 2025, only authorised companies can operate nationally and all federally authorised betting sites use the .bet.br extension.

That is the point readers should hold onto. A lower illegal share does not make every offshore offer harmless. It means the regulated market is gaining ground, while the unauthorised market still has enough volume to keep tempting players with payment shortcuts, looser checks and less visible accountability.

TopGamb readers can connect this with our guides to checking a site’s legal status before deposit, offshore betting shortcuts, regulated iGaming markets and gambling ad certification. The same rule keeps appearing: if the domain, operator and payment method do not line up, slow down.

Why the domain and the cashier still matter

The survey’s payment findings are just as important as the share estimate. Credit cards and crypto can be convenient, but they also make it easier for a player to move outside the regulatory lane without noticing the shift. The official Brazilian framework is built around authorised operators and a visible .bet.br domain, not a scattered set of copycat brands pretending that the logo alone proves legitimacy.

That is why this story has a player-safety angle, not just a market-sizing angle. If an account asks for a payment method that the regulated market does not use, or if the URL does not sit inside the authorised .bet.br space, the player should treat the offer as a problem until proven otherwise.

The practical takeaway is simple. A shrinking illegal share is good news for channelisation, but it does not remove the need for verification. The first check is still the same one: who operates the site, what domain is being used, and what kind of money is being asked for before the first wager is placed.

Reader Questions

Does a lower illegal share mean Brazil’s market is fixed?

No. It means the regulated market is improving, but the study still found a large illegal segment and a lot of non-.bet.br activity.

What is the fastest player check?

Confirm that the site is on a .bet.br domain, that the operator is authorised, and that the cashier does not push you toward payment methods outside the regulated framework.
