Indonesia blocks 3.7 million illegal gambling sites, Vietnam shuts three iGaming networks, and Chile targets 1win and Roobet

There is a lot packed into this batch: enforcement in Indonesia and Vietnam, a tax move in Malta, and fresh pressure on offshore operators in Chile. For high-risk PSPs, the useful bit is not the headlines themselves but the direction of travel: more site blocking, more tax collection, and more scrutiny of offshore-facing gambling flows.

1. Indonesia has blocked 3.7 million illegal gambling sites since 2024. For payment teams, that is another sign that the market is treating unlicensed gambling as an infrastructure problem, not just a content problem: access gets cut, but the underlying payment routes remain the real choke point.
2. Police in Vietnam shut down three iGaming networks that accepted bets on the 2026 World Cup, with turnover of almost $76 million. That is a sizeable flow for a network that was operating outside the local rulebook, and it is the kind of case that usually brings payment trails, intermediaries, and account structures into focus.
3. In the United States, five tribes are asking federal authorities to impose limits on prediction markets. The practical issue here is that prediction markets sit close enough to betting behavior to matter for PSPs, even when the legal wrapper is different.
4. Researchers found signs of manipulation in five-minute Bitcoin contracts on Polymarket. That matters because short-duration, crypto-settled products are exactly where monitoring, market-integrity controls, and transaction review tend to get tested first.
5. Malta will tighten its tax policy from 1 October. The timing matters for operators and PSPs with Maltese entities or exposure to Maltese-facing structures, because tax changes tend to show up quickly in treasury and entity-planning decisions.
6. Africa is losing billions of dollars each year to offshore iGaming, and the unregulated sector generated $17.8 billion in 2025. That is the clearest commercial signal in the batch: offshore gambling is not a niche leakage problem, it is a material revenue pool that regulators and local payment rails will keep trying to reclaim.
7. Chile is reviewing 1win and Roobet as it moves to enforce 19% VAT collection from offshore operators. For PSPs, that is a reminder that tax enforcement can become payment enforcement fast, especially when a jurisdiction decides to make offshore supply pay like local supply.
