Over 10,000 Lawsuits Signal Growing Pains for Brazil’s Regulated Betting Operators

Key Takeaways

• More than 10,627 legal actions: Bettors have filed over 10,000 cases against betting houses since the 2023 Bets Law, with 5,488 in 2025 and 4,037 from January to May 2026.
• R$ 37 billion market: The regulated sector generated R$ 37 billion in revenue in 2025 while facing mounting complaints over blocked withdrawals and addiction.
• 59.2% plaintiff success: Bettors won fully or partially in 59.2% of the 3,438 decided cases, according to Predictus data.
• Concentrated impact: The Southeast accounts for 5,076 cases (48.2%), with addiction-related filings accelerating sharply.

“Quando o apostador para de depositar por uma semana, a bet manda um bônus, ela dá um gerente VIP…” observed attorney Marco Aurélio Leite in reporting covered by BNLData.

That single observation captures a deeper tension now confronting operators in Latin America’s largest regulated betting market. Since the Bets Law received final approval in late 2023, more than 10,000 lawsuits have been filed against online betting companies, according to BNLData’s analysis of Predictus data commissioned by BBC News Brasil. The pace is accelerating alongside revenue that reached R$ 37 billion in 2025.

Litigation Volume Tracks Market Expansion

Predictus scanned 630 million court records and identified 10,627 actions filed since 2018 in which at least one betting house was named. Of those, 5,488 arrived in 2025 and another 4,037 landed in the first five months of 2026, pointing to a full-year total likely exceeding the prior figure. As of the latest tally, 44.1% remain in progress, 17.9% were dismissed without reaching the merits, and 38% have produced a decision.

In the 3,438 fully judged cases, bettors secured full or partial victories in 59.2% (589 complete wins and 1,446 partial), while operators prevailed in 40.8% (1,403 rulings). Another 607 cases, or 5.7% of the total, ended in settlement. These outcomes arrive as 85 companies authorized by the Secretariat of Prizes and Bets operate under 187 distinct brands.

Withdrawal Blocks Dominate the Complaints

The leading category of grievance involves difficulty accessing funds. The data break down into 636 actions over blocked platform accounts, 629 over unilateral rule changes, and 429 over direct withdrawal blocks. Hendrik Eichler, CEO of Predictus, noted that post-fact rule alterations almost invariably result in the same practical outcome: funds do not leave the platform.

One case cited in the BNLData report involved an bettor who accumulated R$ 1.15 million in casino play only to see the account closed unilaterally. Platform lawyers attributed the winnings to a systemic glitch; the plaintiff’s counsel countered that no concrete evidence was produced. The action was filed in May 2025 and remains pending in the 9th Civil Court of Guarulhos. Attorneys describe such retention as a cash-flow management tactic that exploits judicial delays.

Sharp Rise in Addiction and Duty-of-Care Claims

Although smaller in absolute numbers, filings tied to addiction and failure of care are growing rapidly. There were 7 addiction cases in 2024, 27 in 2025, and 52 in the first five months of 2026 for a total of 86. Claims alleging breach of duty of care jumped from 15 in 2024 to 243 in January-May 2026.

These actions rest on a August 2025 responsible-gaming ordinance and Consumer Defense Code concepts of “hypervulnerability.” Leite, who represents plaintiffs in more than 500 actions, reports that courts increasingly order repayment when addiction patterns are shown. In one June 2026 São Paulo appellate ruling, a betting house was ordered to return 50% of roughly R$ 122,000 lost by a diagnosed ludopath after the platform failed to intervene despite clear signals. The court declined full restitution, citing the bettor’s request to reactivate a previously suspended account and the principle against turning the judiciary into “insurance against losses.”

The coverage from BNLData and BBC News Brasil usefully quantifies the surge but underemphasizes the operational mechanics operators can deploy to reduce exposure. Missing is deeper analysis of how real-time behavioral analytics, mandatory self-exclusion enforcement, and transparent rule presentation could compress the litigation pipeline. From an industry lens, these cases reveal where current controls lag behind regulatory expectations rather than merely cataloging disputes.

Geographic Concentration and Labor Overlap

The Southeast region concentrates nearly half the actions with 5,076 cases (48.2%), followed by the Northeast at 3,092 (29.3%). São Paulo leads cities with 908 filings, trailed by Rio de Janeiro (628) and Belo Horizonte (242). Eleven percent of total actions (1,185) sit in labor courts, largely involving severance, overtime, and employment-status claims by staff and contractors rather than bettors.

Where the Risk Lies

Brazil’s regulated betting market has reached an inflection point. The combination of explosive revenue growth and rising legal exposure demonstrates that commercial success alone does not insulate operators from consumer-protection claims. Client-partners who treat duty-of-care obligations as core infrastructure—rather than regulatory checkboxes—will reduce both litigation volume and settlement costs while building durable trust.

The data also caution against viewing every plaintiff victory as a market threat. Many cases turn on specific platform conduct that proactive compliance can prevent. Those operators who invest now in clearer terms, faster dispute resolution, and genuine addiction safeguards will convert today’s legal friction into tomorrow’s competitive advantage in a jurisdiction that remains central to Latin American expansion.
