- Summary: NyesteCasino.com’s weekly review finds the iGaming sector balancing tighter regulation on prediction markets, sweepstakes and credit deposits against continued global growth and World Cup betting demand.
NyesteCasino.com, a leading iGaming analysis resource, released its latest industry overview, highlighting a week defined by intensifying regulatory scrutiny alongside continued global market expansion.
From U.S. Senate hearings and a widening circuit split to the localisation of crypto casinos and a surge in World Cup betting activity, iGaming operators have been balancing risk management with aggressive growth strategies.
Over the past week, the global iGaming sector has faced two powerful and often conflicting forces. Regulators across the United States, Europe, Southeast Asia, and South America have tightened rules around prediction markets, sweepstakes casinos, and credit card usage for deposits. At the same time, online gambling platforms, content providers, and policy advisors have accelerated product innovation and executed timely, region-specific sports marketing campaigns.
According to NyesteCasino.com’s team, these developments signal a broader structural transition across the industry—one in which compliance agility is rapidly becoming as critical to success as product quality. Despite increasing regulatory headwinds, the pace of innovation and market demand continues to point toward sustained sector growth.
Prediction Markets: Courtrooms, Congress, and Cross-Border Bans
The week started with a long-awaited US Senate Commerce Subcommittee gathering. The hearing named “No Sure Bets” took place on May 20 under Chair Marsha Blackburn, and Blackburn indicated more sessions were to come. The debate between American Gaming Association CEO Bill Miller and former Congressman Patrick McHenry quickly turned into a clash over the future of prediction markets. While Miller named the sports event contracts as backdoor betting operations bypassing the state licences, tax regulations, and integrity safeguards, McHenry talked on behalf of the Coalition for Prediction Markets and opposed him, stating that the current CFTC supervision is working perfectly.
On 22 May, a panel from the Ninth Circuit rejected the stay requests filed by both Kalshi and Polymarket, refusing to halt state enforcement proceedings in Nevada and Washington, which complicated the legal situation even more. The court ruled that a federal preemption defence under the Commodity Exchange Act cannot, on its own, establish federal jurisdiction. The ongoing disagreement in the appeals court of New Jersey, which had previously upheld a Kalshi injunction, has gained strength with this decision. Moreover, the process leading to a Supreme Court review of state jurisdiction over event contracts has accelerated even more.
Indonesia’s Ministry of Communication and Digital Affairs categorised Polymarket as an online gambling site, disregarding its crypto-based structure, and has requested a national ban on the market platform on May 25. The reason for this request was a viral contract regarding whether President Prabowo Subianto would resign before the end of his term in October 2029. The contract generated a trading volume of approximately $46,000. The number of jurisdictions where Polymarket is inaccessible is growing, exceeding 33 around the world now, including India, Brazil, and Singapore, among other new blockers.
State-Level Regulations: An Anti-Sweepstakes Bill from Tennessee
There have also been state-level restrictions in Tennessee on online gambling law. During the same week, Governor Bill Lee signed two vital bills. Senate Bill 2136 made Tennessee the ninth US state banning sweepstake casinos and dual-currency systems completely, which grants the attorney general the power to enforce it. And according to the SB 1992, the second bill signed by the governor, anyone who deliberately influences the outcome of an event whilst holding a prediction market contract will be charged with a Class E felony. It is expected that these bills will guide other state legislatures who are planning similar regulations at the moment.
Europe and Brazil: Tax Proposals, Ad Restrictions, and Credit Bans
The European Parliament held a plenary debate on May 20 on a proposed EU-level gambling levy. Budget Commissioner Piotr Serafin confirmed the Commission is actively assessing the option alongside digital services and crypto-asset levies as part of the next Multiannual Financial Framework. Proponent MEP Victor Negrescu estimated the levy could raise between €2 and €4 billion annually for education, youth, and addiction prevention programmes. Opponents from EPP and ECR blocs raised concerns over subsidiarity, competitiveness, and national tax sovereignty, with any operational package targeted for January 2028.
Belgium’s Kansspelcommissie and the Netherlands Gambling Authority separately issued formal World Cup advertising warnings to licensed operators ahead of the June 11 to July 19 FIFA tournament. France’s ANJ flagged a year-on-year rise of more than 25% in operator marketing budgets as the tournament approaches. Meanwhile, Brazil formalised rules on May 25 to close off Pix Crédito as a deposit method on regulated betting platforms, a move prompted in part by a Folha de São Paulo audit revealing that major banks including Bradesco and Banco do Brasil, were still processing credit transfers into betting accounts as recently as mid-May.
Editorial Perspective
“What this week makes clear is that the iGaming sector is entering a phase where regulatory IQ is as strategically important as product development,” said the editorial team at NyesteCasino.com. “The prediction markets debate alone spans courtrooms, congressional hearings, and international bans and it is far from resolved. Operators who can track and adapt to this multi-jurisdictional complexity while still executing on World Cup campaigns and localisation strategies will be best positioned for the second half of 2026.”

Editorial Commentary
The thread most likely to define the second half of the year is the prediction markets dispute. The Ninth Circuit declined to pause state enforcement against Kalshi and Polymarket in Nevada and Washington, a ruling that sits alongside earlier actions such as the Massachusetts lawsuit against Kalshi and points the federal-versus-state question toward the Supreme Court. Indonesia’s move to block Polymarket reflects the same cross-border enforcement gap European regulators have flagged, including the Danish authority’s limited reach over event contracts.
On the European side, the proposed EU-level levy and the World Cup advertising warnings in Belgium and the Netherlands add to the tax and compliance load operators already carry after the UK’s gambling duty increases. Brazil’s decision to close Pix Crédito as a deposit route points in the same direction. Operators that build compliance into how they run rather than bolt it on will be better placed as the regulatory map keeps moving through the rest of 2026.
