UK Sports Betting Market Statistics 2025: What the Data Reveals
Available in US
If you want to understand why UK bookmakers fight so aggressively for basketball betting volume — better odds, more markets, enhanced promotions during NBA windows — the answer is in the numbers. The UK gambling market is enormous, growing, and intensely competitive. Basketball sits within it as a fast-expanding segment of a market that already processes around 290 million online bets on real events every month. Knowing the scale of the industry you are participating in is not just interesting context. It shapes everything from the bookmakers’ pricing decisions to the regulatory environment you operate within.
The figures that follow are drawn from official Gambling Commission annual statistics and related government data — primary sources that no other basketball betting resource in the UK has assembled in one place.
Market Size and Growth
The UK gambling industry generated £16.8 billion in Gross Gambling Yield (GGY) in the financial year to March 2025 — a 7.3% year-on-year increase. GGY represents the net revenue retained by operators after paying out winnings; it is the industry’s equivalent of revenue. That figure makes the UK gambling market one of the largest in the world by per-capita participation.
Within that total, the Remote Casino, Betting and Bingo sector — which covers all online gambling including sports betting — generated £7.8 billion, up 13.1% year-on-year. This sector now accounts for 46% of total UK gambling market revenue, having grown from a much smaller share a decade ago. The shift toward online is structural and appears durable.
The government’s take from online gambling has followed the same trajectory. Remote Gaming Duty — the tax applied to online operators’ gross profits — totalled £1.163 billion in 2024-25, an increase of £135 million (13%) compared to the previous year. That growth in tax yield reflects both the expansion of the online market and the ongoing shift of formerly in-person betting to digital channels.
Online GGY grew by 7% year-on-year to £1.45 billion in Q4 2024-25 (the January to March quarter), with casino products — particularly slots — driving the headline growth at 11% year-on-year. Sports betting growth was more modest within that quarter but continues the multi-year trend of expansion in the remote sector.
For context on what this means for basketball specifically: more UK online betting revenue means more competition between operators for bettor attention and action, which in practice means better odds, deeper markets, and more aggressive promotional offers — all of which benefit informed bettors who know how to navigate the market.
Active Accounts and Betting Volume
The scale of participation in UK online gambling is remarkable when expressed in concrete figures. The average number of active online accounts per month in Q4 2024-25 was 13.5 million. That is not accounts created — it is accounts that placed at least one bet during the month. The figure represents roughly a quarter of the UK adult population maintaining actively used online gambling accounts.
Bet volumes have grown in parallel: the number of bets placed increased 5% year-on-year in the same quarter, while the number of accounts grew by 2%. This means the average active bettor is placing more bets than in previous years — a trend consistent with the growth of in-play betting, which enables higher frequency wagering within individual events.
Real event betting — the category that includes sports betting, as distinct from casino products — generated £596 million in GGY in Q4 2024-25, a 5% year-on-year increase. This is the sector that captures NBA betting, EuroLeague wagering, and British Basketball League markets alongside football, horse racing, and other sports.
The 290 million monthly online bets on real events figure contextualises what it means to be a participant in this market. Even a specialist basketball bettor placing 200 bets per year represents a tiny fraction of total volume — and that volume is what creates the liquidity and price competition that makes serious basketball betting possible in the UK. The market’s depth is your operational context.
Sports Betting Participation Rates
More than 5% of British adults bet on sport online as of 2024, making sports betting one of the most widely practised forms of gambling outside of the National Lottery. Among all forms of gambling, sports betting ranks second in participation after lotteries — around 47% of UK gamblers include sports betting among their activities.
The distribution across sports skews heavily toward football, which dominates UK sports betting volume in a way that has no real equivalent in any other market globally. Basketball’s position within UK sports betting has been growing — it now ranks behind football and cricket but ahead of most other American sports among online betting options — and that growth is being driven by NBA coverage expansion on UK television and streaming platforms alongside the demographics of online betting.
Mobile betting’s role in this growth is decisive. Among UK bettors aged 18 to 24, 76% use their mobile phone as the primary device for gambling — the highest rate across all age groups. NBA basketball’s primetime viewing window in the UK (late evening, often midnight or later for West Coast games) aligns naturally with mobile betting behaviour, which partly explains why UK bookmakers have invested in deepening their NBA in-play mobile offerings specifically. The bettor audience that watches these games is predominantly young, mobile-first, and accustomed to in-play wagering.
The UK’s share of global sports betting is not small. At 11.1% of world sports betting revenues in 2024, the UK punches well above its weight relative to population size — a reflection of the historically liberal regulatory environment, the density of the bookmaking infrastructure, and the deep cultural integration of betting with sports consumption. That position is now evolving under the 2025 regulatory reforms, which have introduced structural changes to how operators must interact with customers.
For the full picture of what those 2025 regulatory changes mean — the Gambling Levy, the new stake limits, and the consumer protection framework that now governs UK betting — the detailed breakdown in UKGC gambling regulations 2025 covers every element relevant to sports bettors operating within this market.
How large is the UK online sports betting market in 2026?
The UK gambling market as a whole generated £16.8 billion in Gross Gambling Yield in the year to March 2025, with the online remote sector accounting for £7.8 billion — a 13.1% year-on-year increase. Real event betting (sports betting) generated £596 million in GGY in Q4 2024-25 alone. The market is among the largest globally in per-capita terms and continues to grow primarily through the shift from physical to online channels.
How many people bet on sports online in the UK each month?
The Gambling Commission’s data shows 13.5 million average active online accounts per month in Q4 2024-25 across all gambling categories. Approximately 290 million online bets on real events (sports betting) are placed monthly in the UK. More than 5% of British adults bet on sport online, and around 47% of UK gamblers include sports betting among their activities — making it the second most popular form of gambling after lotteries.
