The Global Expansion of Legal Sports Betting

Sports betting is in the middle of one of its most dramatic regulatory transformations in history. Driven by shifting public attitudes, mounting tax revenue opportunities, and the decline of unregulated offshore markets, governments across North America, Europe, Africa, and beyond are actively reshaping their legislative frameworks. Here's a look at the key trends defining the industry in 2025.

The United States: A Maturing Market

The 2018 Supreme Court decision to strike down PASPA — the law that effectively banned sports betting outside Nevada — opened the floodgates for state-by-state legalisation. As of 2025, the majority of US states now have some form of legal sports betting, either live or in the legislative pipeline.

Key developments in the US market include:

  • Online dominance: Mobile and online wagering accounts for the vast majority of handle in states where it's permitted, far outpacing retail sportsbook locations.
  • Remaining holdouts: Several states — including California and Texas — have significant populations but have yet to legalise, making them the most-watched potential markets in the industry.
  • Consolidation: The competitive wave of new market entrants has given way to a smaller number of dominant national operators capturing most of the market share.
  • Responsible gambling regulation: State regulators are increasingly mandating responsible gambling features and advertising restrictions as a condition of licensing.

Europe: Tightening Regulation

While Europe has long had established regulated betting markets, 2025 is characterised by tightening restrictions rather than expansion:

  • UK: The Gambling Act Review process has produced proposals for stake limits on online slots and enhanced affordability checks. The industry continues to adapt to a more interventionist regulatory environment.
  • Netherlands: Launched its regulated online market in 2021; regulators have since moved to restrict advertising and improve compliance.
  • Germany: Operating under a challenging new treaty framework with strict product restrictions and ongoing market adjustments.
  • Spain, Italy, France: Established markets operating under relatively stable regulatory conditions, though advertising bans have continued to tighten in several jurisdictions.

Emerging Markets: Africa and Latin America

Some of the most significant growth in legal sports betting is occurring in emerging markets:

  • Brazil: After years of legislative delays, Brazil has moved firmly toward a regulated sports betting framework, representing one of the largest potential markets in the world given its football-obsessed population.
  • Africa: Mobile-first betting markets across Nigeria, Kenya, Ghana, and South Africa continue to expand rapidly, driven by smartphone penetration and young populations.

Technology Trends Reshaping Betting in 2025

Beyond regulation, technology continues to transform how bettors engage with sportsbooks:

  • In-play betting growth: Live wagering now represents a growing share of total betting handle globally, driven by improved data feeds and faster oddsmaking.
  • Same-game parlays: US operators in particular have popularised same-game parlay products, which combine multiple selections from a single game into one wager.
  • AI and personalisation: Operators are using machine learning to personalise promotions, detect at-risk behaviour, and adjust risk management.
  • Cryptocurrency: While not mainstream, a number of operators now accept crypto deposits, and blockchain-based betting platforms continue to develop.

What to Watch for the Rest of 2025

  1. Legislative developments in California and Texas — either state passing legalisation would be a landmark event
  2. The rollout and impact of Brazil's new regulatory framework
  3. Further UK Gambling Act reform implementation
  4. Continued operator consolidation through mergers and acquisitions
  5. Expanding responsible gambling mandates in newly regulated markets

Key Takeaway

The global sports betting industry is simultaneously expanding into new markets and facing increased regulatory scrutiny in established ones. For bettors, this means more options in more locations — but also more obligations around identity verification and responsible gambling compliance. Staying informed about your local regulatory environment ensures you're always betting legally and safely.
