Brazil Loses $12.5B to Gambling; Unlicensed Market Dominates in 2025 Study

Brazil's Unlicensed Gambling Market Dwarfs Legal Sector

A comprehensive study released in early August 2026 has quantified the scale of Brazil's gambling losses and underground economy. Brazilian families lost $12.5 billion to gambling activities during 2025, with between 41% and 51% of that market consisting of transactions on unlicensed and illegal gambling websites.

Context

The findings align closely with projections published by LCA, a research firm specialising in gaming market dynamics. Brazil has been moving toward formalised iGaming regulation for several years, but implementation has proceeded slowly, and illegal gambling sites have captured the majority of consumer demand, particularly among lower-income Brazilians. The $12.5 billion figure represents consumer losses — money wagered minus winnings — meaning the total addressable market is substantially larger.

What This Means

For B2B suppliers targeting Brazil's iGaming market, this study confirms the regulatory imperative driving Brazil's push toward operator licensing. The massive unlicensed market represents both a threat and an opportunity: suppliers helping licensed operators compete against illegal sites, or providing compliance solutions to help regulators combat underground gambling, will find strong demand.

What to Watch

Whether Brazil's regulator accelerates enforcement against unlicensed sites in response to the study, and whether the licensed market's share of total wagering improves in subsequent quarterly data.
