NBA Betting Market Statistics: Revenue, Growth, and Key Data Points
Available in US
Numbers don’t just support the story of basketball betting’s growth — they are the story. I’ve tracked these market figures annually since 2018, and the trajectory is staggering. The industry has expanded from a niche segment of the sports betting landscape into a multi-billion-pound global market that shapes everything from how games are broadcast to how leagues structure their partnerships. If you bet on basketball, understanding the size and direction of the market you’re operating in isn’t academic curiosity — it’s context that informs every aspect of your activity.
Global Basketball Betting Market Size and Projections
When I first started covering basketball betting markets, reliable size estimates were hard to find. The industry was fragmented, much of the activity was offshore or unregulated, and the data that existed was heavily US-centric. That’s changed dramatically. Multiple research firms now track the global basketball betting market with methodological rigour, and the numbers paint a consistent picture of rapid expansion.
The global sports betting market is valued at $124.88 billion in 2026, with projections reaching $325.71 billion by 2035 at a compound annual growth rate of 11.24%. Basketball’s share of that total is substantial. The basketball betting market specifically was valued at $8.7 billion in 2024 and is projected to reach $18.4 billion by 2033, growing at a CAGR of 8.7%.
Global basketball betting gross win — the amount retained by operators after paying out winnings — reached $7.9 billion in 2024. That figure is projected to climb to $10.1 billion by 2026 and $11.1 billion by 2028. The gap between the handle (total amount wagered) and gross win (what operators keep) reflects the effective margin across the industry, and the growth in gross win indicates both expanding volume and stable (or slightly increasing) margins.
The NBA dominates this landscape. NBA betting generates roughly 60% of all basketball betting revenue worldwide, with the remainder split among EuroLeague, national European leagues, college basketball, and other competitions. Basketball accounts for 15 to 18% of global sports betting activity overall, rising to approximately 31% among certain US-based operators where the sport’s cultural prominence drives disproportionate engagement.
Sports betting occupies 52% of total online gambling revenue globally, making it the largest segment ahead of casino, poker, and bingo. Within sports betting, basketball’s share has grown faster than the overall market for five consecutive years, driven by the NBA’s global audience expansion and the legalisation wave across US states.
US vs UK Market Share in Basketball Wagering
I find it useful to compare the two markets side by side, because UK punters are betting into a global ecosystem heavily influenced by American dynamics — even when they’re placing bets through UK-licensed operators.
Americans legally wagered $166.94 billion on sports in 2025, generating $16.96 billion in sportsbook revenue — a 22.8% increase year-on-year. Tax revenues from sports betting hit $3.71 billion, growing 32.4% over the prior year. The US market is the engine of global sports betting growth, and basketball is one of its primary fuels.
The UK gambling industry generated GBP 16.8 billion in gross gambling yield across all products in the year to March 2025, with online betting and casino contributing GBP 7.8 billion — 46% of the total market. The UK’s sports betting segment is mature and well-regulated, but basketball represents a smaller share of activity than it does in the US. Football dominates UK sports betting, and basketball competes with horse racing, tennis, and cricket for the remaining attention.
North America holds approximately 55% of the global basketball betting market, reflecting both the NBA’s domestic dominance and the recent explosion in legal state-by-state wagering. Asia-Pacific is the fastest-growing region, driven by basketball’s popularity in countries like the Philippines, China, and Australia. Europe — including the UK — occupies a middle position: established, regulated, and growing steadily, but without the dramatic expansion curve of North America or Asia-Pacific.
FanDuel and DraftKings together control roughly 75% of the US sports betting market by handle. Their dominance influences the global market because their lines — particularly their NBA closing lines — serve as the benchmark against which other sportsbooks, including UK operators, calibrate their own pricing. Understanding this dynamic matters for UK bettors: the prices you see on your UK sportsbook are shaped by market forces originating primarily in the American market.
Who Bets on Basketball: Demographics and Behaviour
The demographic profile of basketball bettors has shifted meaningfully in the past five years, and the trends have direct implications for how markets behave, what products operators develop, and where the industry is heading.
The 25-34 age group constitutes 34% of sports bettors in the US, with the 35-44 group adding 31%. Together, the 25-44 demographic accounts for 65% of the active betting population. Men represent approximately 69% of US bettors and 70% of the global betting population. These figures are consistent across markets and haven’t changed dramatically in recent years, though the gender gap is slowly narrowing as operators expand their marketing reach.
The fastest-growing demographic segment is the 18-24 age group, expanding at a compound annual rate of nearly 12% through 2031. This cohort has grown up with smartphones, social media, and legal sports betting as default features of their sports experience. They’re the first generation for whom placing a bet on an NBA game is as natural as checking the score. Their influence on market products — SGPs, micro-betting, social betting features — is already visible and will accelerate.
About 22% of American adults had an active online sportsbook account in early 2025. Among men aged 18-49, that figure rises to 48% — nearly half. In the UK, participation in online sports betting sits at around 8% of the adult population over any four-week period. The gap between US and UK penetration rates reflects cultural factors (basketball’s relative prominence), regulatory history (the UK legalised online betting decades before most US states), and product maturity.
Mobile devices drive the overwhelming majority of this activity. Mobile platforms handle over 80% of online gambling revenue in the US and over 53% globally. For basketball betting specifically, the mobile share exceeds 70%, reflecting the sport’s on-the-go consumption patterns and the prevalence of in-play betting, which is almost exclusively a mobile activity for most punters.
Growth in March Madness betting offers a seasonal marker of the broader trend. Wagering on the NCAA tournament rose 33% in 2026 among adults aged 21 and older in legal states. That seasonal spike underscores basketball’s cyclical betting appeal — the NBA regular season sustains baseline volume, the playoffs and March Madness create peaks, and the off-season creates a trough that futures markets partially fill.
How big is the global basketball betting market?
The global basketball betting market was valued at approximately $8.7 billion in 2024, with projections to reach $18.4 billion by 2033 at a compound annual growth rate of 8.7%. Global basketball betting gross win — the amount retained by operators — reached $7.9 billion in 2024 and is expected to exceed $10 billion by 2026.
What percentage of UK gambling revenue comes from basketball?
The UK Gambling Commission does not publish sport-specific breakdowns of gambling revenue. Within the total UK GGY of GBP 16.8 billion, basketball represents a small portion of the sports betting segment, which itself sits within the GBP 7.8 billion online gambling category. Football dominates UK sports betting, with basketball, horse racing, tennis, and cricket competing for the remaining share.
What age group bets on basketball the most?
In the US, the 25-34 age group represents the largest single demographic of sports bettors at 34%, followed by 35-44 at 31%. The fastest-growing segment is 18-24, expanding at a compound annual rate of nearly 12%. Data specific to basketball betting within these age groups is limited, but the NBA’s younger audience profile suggests basketball betting skews slightly younger than the overall sports betting population.
