For most of the last century the official story about gambling harm was individual: some people can’t control themselves, the industry offers responsible-gambling tools, and everyone else is fine. In November 2024 The Lancet Public Health published a full Commission — an invited, multi-author review with recommendations — that rejects that framing and replaces it with the one public health has used for tobacco and alcohol. Gambling harms are produced by an industry, distributed unequally, and shaped by political and commercial decisions. The Commission’s stated aim is to “raise awareness of the public health risks associated with current trends in commercial gambling development” and to give international, national and regional actors a playbook.

The numbers it assembles are the useful part, because they replace the vague sense that gambling is everywhere with a scale.

  • The market: consumer net losses are projected to reach nearly $700 billion by 2028; online gross gambling yield alone is forecast to grow from $75.4bn (2021) to $205.6bn (2030). Gambling is legally permitted in some form in more than 80% of countries.
  • Participation: an estimated 46.2% of adults and 17.9% of adolescents gambled in the previous year, globally. 10.3% of adolescents gambled online — despite broad agreement that commercial gambling for minors should be prohibited.
  • Harm prevalence: about 5.5% of women and 11.9% of men experience at-risk gambling. Extrapolated, that is roughly 448.7 million adults, of whom an estimated 80 million live with gambling disorder or problematic gambling.
  • Product matters enormously: gambling disorder is estimated to affect 15.8% of adults and 26.4% of adolescents who use online casino or slot products, and 8.9% of adults and 16.3% of adolescents who use sports betting products. The harm rate is a property of the product’s design, not of the population’s character.
  • Revenue is concentrated in the heaviest users: in Canadian operator data, the top 20% most active customers accounted for 92% of sports bets and 90% of online casino activity. In the US, 5.7% of sports bettors generated 80% of spending, and 4.9% of online casino players generated 80% of revenues.

That last set of figures is the quiet indictment. An industry whose revenue depends on a small minority of customers betting destructively cannot be fixed by telling those customers to be more responsible, and the Commission says so directly — it devotes a section to “the end of responsible gambling,” arguing the concept has functioned as industry cover, and it identifies the “corporate playbook” the sector uses to shape regulation, including the political economy of who gets the tax revenue.

Which is the thread back to the older material in this feed. State-owned operators often return over 50% of gross gambling revenue to the state or to earmarked causes, and states have fought hard — including against the federal government and against tribes — over that revenue. The Commission’s framing makes the mechanism visible: the harm is the product, the revenue is the prize, and the regulation is the negotiation over the split.
