Regulators tighten their grip as prediction markets, tax hikes, and enforcement measures collide across key jurisdictions.

This week underscores a clear shift toward tighter oversight and enforcement. The US is moving to centralise control over prediction markets as integrity concerns grow, while the UK’s affordability checks and sharp tax hike mark a more aggressive regulatory stance. Elsewhere, regulators are strengthening compliance measures while warning that rising costs could push activity toward unlicensed markets.

Let’s dive into this week’s Regulation Roundup

Tax Issues

• CFTC sues Arizona, Connecticut and Illinois to assert exclusive jurisdiction over prediction markets
  
  The Commodity Futures Trading Commission filed lawsuits against all three states on April 2, challenging their efforts to restrict or ban CFTC-registered prediction market platforms. CFTC Chairman Michael Selig argued that Congress granted the federal government sole authority to regulate event contracts under the Commodity Exchange Act, and that state-level enforcement would create an unworkable patchwork of regulation. The CFTC is also pursuing a formal rulemaking process for prediction market oversight, with a 45-day public comment window underway.

• NFL sends letters to Kalshi and Polymarket demanding removal of manipulable sports markets
  
  The NFL sent letters on April 1 to Kalshi and Polymarket asking both platforms to stop offering contracts on events deemed susceptible to manipulation or insider information, including markets tied to announcer commentary, celebrity attendance at games, draft picks, player signings, officiating decisions, and injuries. CFTC Chair Michael Selig indicated the agency would defer to leagues on which markets are prone to manipulation. The NFL currently has no formal partnership with either platform, in contrast to the NHL and MLB, both of which have struck commercial agreements with prediction market operators.

• UK Gambling Commission launches national affordability check rollout
  
  The UKGC confirmed on April 2 that its affordability check framework is now rolling out across all licensed online casino operators, forming the centrepiece of a major overhaul of British gambling regulation. Following a 12-month pilot with major operators and UK credit reference agencies, full compliance is required by Q3 2026. Operators face potential licence revocation for failing to implement the framework within the compliance window.

Legislative Hikes

• UK Remote Gaming Duty doubles to 40% as industry braces for spiral effect
  
  The UK's Remote Gaming Duty increase from 21% to 40% took effect on April 1, the steepest single-step tax increase in British gambling history. Industry analysts warn of a potential spiral effect in which operator cost-cutting reduces revenue, prompting further cuts and accelerating player migration to unlicensed offshore platforms. The UK government allocated an additional 26 million pounds to the UKGC for enforcement against illegal operators, though multiple industry sources have questioned whether that total is sufficient.

• Entain closes 39 Ladbrokes shops in Ireland after sale talks collapse
  
  Entain confirmed on April 1 it will close 39 Ladbrokes betting shops in the Republic of Ireland, representing over a third of its Irish estate and putting approximately 226 jobs at risk, after negotiations to sell the entire Irish retail network to Bar One Racing ended without a deal. Six further shops in Northern Ireland are also under review. The closures, expected to be finalised by end of May, reflect the broader migration of gambling activity online and cost pressures following the UK Remote Gaming Duty increase, with Entain and Evoke among operators restructuring their retail footprints in response.

Enforcement and Compliance

• Netherlands KSA issues new problem gambling intervention guidelines and warns sportsbooks over illegal markets
  
  The Dutch Gambling Authority published a detailed guidance manual on April 6 clarifying how licensed operators must handle interventions with problem gamblers, including specific timelines and communication requirements for referring at-risk players to the national Cruks self-exclusion register. In a separate action the same day, the KSA warned licensed sportsbook operators that some were offering wagers on subjective outcomes such as MVP awards, which fall outside Dutch law. The operators removed the non-compliant markets immediately following contact from the regulator.

Emerging Markets

• South Africa's proposed 20% online gambling tax draws fresh industry backlash over black market risk
  
  Industry analysts published detailed responses this week to South Africa's 2026 Budget proposal to impose a 20% national GGR tax on online betting and interactive gambling, warning the combined effective rate of 26-29% on top of existing provincial taxes could push players and operators toward unlicensed offshore platforms. The concern echoes Kenya's experience with a similar levy, which saw operators exit and tax revenues fall. The bill is expected to be submitted to Parliament in 2026, with a final decision anticipated in early 2027.
