U.S. Gambling Spend Reaches $172 Billion as Digital Markets Surge

In 2024, total gambling spend in the United States grew to $172 billion, marking a 3.3% year-over-year increase. This growth came primarily from the digital sector, with mobile sports betting, online casinos, and iLottery showing strong performance.

Although retail casinos still dominate overall spend, online platforms are expanding faster. States like North Carolina and Vermont fueled this growth by legalizing digital betting, adding new momentum to an already growing market.

Online Gambling Leads the Surge

Digital gambling verticals recorded the highest growth in 2024. Mobile sports betting climbed by 34%, while online casino games and poker rose by 29%. iLottery followed with a 26% increase, despite holding just 1% of total spend.

Consumers are shifting toward digital experiences. Legal access, improved interfaces, and mobile convenience all contribute to this surge. As more states follow suit, these digital trends are expected to accelerate.

Retail Gambling Remains a Revenue Powerhouse

While digital verticals are growing fast, retail casinos continue to generate the most revenue. Tribal and commercial casinos combined for 56% of total spend. In terms of Gross Gaming Revenue (GGR), their share rose to 61%, underscoring their strong performance.

In-person wagering still makes up 85% of gambling revenue. This shows that while players enjoy digital platforms, many still prefer the physical casino experience, especially for high-stakes play and social interaction.

Future Outlook: Digital Growth to Shape the Industry

Looking forward, digital gambling is likely to shape the next phase of market expansion. More states are expected to legalize mobile betting and iCasino options. Meanwhile, better technology will make platforms faster and more immersive.

The data didn’t include social casinos, sweepstakes, or skill-based gaming, which means the true size of the digital market is even larger. Innovations like virtual and augmented reality could soon transform online gambling, creating new opportunities for players and operators.
