UK Betting Industry Size: GGY, Turnover and Market Share
Available in US
The size of the UK horse racing betting market can be measured in three ways – turnover, gross gambling yield (GGY) and levy yield – and each of these metrics tells a different story about the health of the sector in 2024-2025. Turnover is what punters stake; GGY is what bookmakers keep; levy yield is what flows back to racing. The three numbers move in different directions at different times, and that divergence is the most consequential feature of the current UK racing economy. Get the metrics confused and the headline you read could mean almost anything.
Why does this matter to a punter? Because the structural forces shaping prices, account limits, affordability check thresholds and the racing programme itself are downstream of these numbers. The contraction in turnover is why bookmakers have tightened limits on professional accounts; the rising GGY share captured by overseas operators is part of why the levy debate is so intense; the levy yield is what funds the prize money your bets are competing for. Knowing the size and shape of the market is part of understanding the environment you’re operating in.
GGY and Turnover Defined
Turnover is the total amount staked by punters across all bets in a given period. If a punter places ten £10 bets, the turnover is £100 regardless of whether those bets win or lose. Turnover is a measure of activity, not of bookmaker income, and it is the metric most useful for understanding the volume of public engagement with racing.
Gross gambling yield (GGY) is what’s left for the bookmaker after winnings are paid out. If a punter stakes £100 over a series of bets and receives £90 back in winnings, the GGY on those bets is £10. GGY is the metric the UK Gambling Commission and the regulated betting industry primarily report, because it measures actual economic activity by the operators rather than gross flows.
The relationship between turnover and GGY is governed by the bookmaker margin – sometimes called the overround or hold percentage. Across UK horse racing, the typical margin sits somewhere between 5% and 12% of turnover depending on race type, market and operator. A high-margin meeting with casual punters produces more GGY per pound of turnover than a tight-market professional environment.
The third metric, levy yield, is the statutory contribution from regulated bookmaker GGY back to the racing industry – set at 10% of relevant gross profits above the £500,000 threshold. Levy yield is what funds prize money, integrity, veterinary research and racecourse infrastructure. It is the metric most closely tracked within the sport itself.
None of the three metrics is “the” right number to look at. Each tells a different story, and the health of the sector depends on all three moving in compatible directions. The current concern in UK racing is that they are not – turnover is falling, GGY is holding up or rising, and levy yield is rising in absolute terms but from a contracting underlying base.
Horse Racing’s Share of the UK Gambling Market
The Gambling Commission’s annual industry statistics provide the most authoritative breakdown of where horse racing sits within the broader UK gambling sector. For the financial year April 2024 to March 2025, total remote betting GGY in the UK reached £2.6bn, with football leading at £1.3bn and horse racing second at £766.7m. The year before that – 2023-24 – horse racing GGY had been £771.1m on a slightly smaller total remote betting GGY of £2.4bn.
The headline read across two years: total remote betting GGY grew, but horse racing’s contribution slipped slightly in absolute terms and meaningfully in market share. Racing is no longer the largest remote betting category in the UK by a clear margin – football overtook it some years ago – and the gap has widened with each successive year.
The broader picture is larger still. Total remote GGY across all online gambling categories – Remote Casino, Betting and Bingo – was £7.8bn for the same financial year, with online casino alone accounting for £5.0bn of that figure. Slots within the casino segment contributed £4.2bn. The remote betting category, of which horse racing is a part, is one slice of a much bigger online gambling pie, and racing’s share of that overall pie has been shrinking steadily.
The retail picture adds another layer. As of 31 March 2025, the UK had 3,086 licensed gambling operations and 5,825 betting shops – the shop count down from previous years as high-street consolidation continues. Retail betting remains a significant part of the racing economy, particularly for older punters who don’t use online accounts, but the proportion of total stake routed through shops continues to fall.
The combined retail and online picture for horse racing is one of a sector with a still-meaningful absolute footprint – £766.7m in remote GGY alone, before counting retail – but a shrinking share within a gambling market increasingly dominated by casino games and football betting.
The Decline 2022-2025
The most concerning numbers in the recent UK racing economy concern turnover rather than GGY. The BHA, drawing on bookmaker-reported data, has been tracking a sustained turnover decline across multiple consecutive quarters.
Total betting turnover on British racing fell by 6.8% in 2024 alone, and by 16.5% against 2022. Premier vs Core fixture data revealed an even sharper picture within those numbers – Core fixtures saw turnover collapse by 14.4% in Q1 2025 alone, while Premier fixtures held roughly steady. The differential tells a story about which parts of the racing programme are losing engagement and which are retaining it.
Stretching back further, the picture is starker still. Online turnover on British racing has fallen by approximately £1.6bn since 2022, according to UKGC data for the financial year ending March 2024. When this figure is adjusted for inflation, the Racing Post described it as a “£3bn black hole” in the sector’s finances. The contraction is not subtle, and it is the underlying force shaping every other debate in British racing right now.
Multiple causes have been identified, and the relative weights are contested. The affordability check threshold reductions from 2024 onwards captured a significant slice of higher-staking activity. The growth of the unlicensed offshore market diverted further activity outside the regulated perimeter. The competition from football and online casino has reshaped where casual gambling spend goes. The economic environment more broadly has compressed discretionary household spending on entertainment.
Grainne Hurst, the chief executive of the Betting and Gaming Council, summarised the tension produced by these dynamics: “For the fourth year running, contributions have increased to record levels. This demonstrates the growing, long-term investment regulated betting provides British horse racing. But it is concerning to see once more despite record levy contributions, racing continues to struggle, both as a sport and as a betting product, with betting turnover down again year-on-year.” That statement captures the paradox of the current period – record levy returns sitting on top of declining underlying engagement, and the question of how long the equilibrium can hold.
The decline has direct implications for the industry’s infrastructure. The £4.1bn of total direct, indirect and associated expenditure that British racing generates annually, and the roughly 85,000 jobs it supports across the UK, ultimately depend on punter engagement holding up. Falling turnover threatens both the betting-derived income (levy, sponsorship, media rights) and the broader audience economy (attendance, hospitality, retail) that fund the sport.
Online Versus Retail Trends
The online and retail segments of UK racing betting are moving in different directions. Online has been the engine of growth across the past two decades – the sector has captured a steadily rising share of total stake from retail – but the recent contraction has hit online turnover particularly hard. The £1.6bn online turnover drop since 2022 is concentrated in the online segment, with retail showing a slower and shallower decline over the same period.
The 5,825 betting shop count as of March 2025 reflects a long-term contraction in the retail estate. High-street consolidation accelerated through the 2010s after the introduction of stake limits on fixed-odds betting terminals, and that consolidation has continued into the present. The remaining shops are concentrated in older demographics and locations where online uptake has been slower, but the trajectory is downward.
For racing specifically, the retail segment retains importance disproportionate to its share of total stake. Many older racing punters still prefer the shop environment, and the larger meetings – Cheltenham, the Grand National, Royal Ascot – see significant cash-betting spikes in retail that the online accounts don’t fully capture. Retail is shrinking, but it remains a meaningful slice of the racing-specific economy.
The online segment, while still the larger and more dynamic part of the market, is now operating under constraints that didn’t apply a few years ago. Affordability checks, slower customer acquisition through advertising restrictions, and stake-limit volatility for winning customers have all combined to compress the engagement intensity of the online segment.

FAQ
Why is GGY the standard reporting metric rather than turnover?
GGY measures actual operator revenue and is the closest equivalent to a "sales" figure for the gambling industry. Turnover can be a misleading top-line number because the same money can be staked multiple times within a single session – a £10 bet that wins £20 can become a £30 stake on the next race, and so on. GGY captures the genuine net commercial activity of the sector, which is why regulators and industry bodies report on it primarily.
What"s the relationship between levy yield and GGY?
Levy yield is roughly 10% of UK horse racing GGY above the £500,000 per-operator threshold, with some adjustments for the relevant gross profits calculation. So a £766.7m horse racing GGY produces a levy yield in the £100m range, depending on which operators clear the threshold and how the relevant gross profits are computed. The recent levy yield of £108.9m for 2024-25 is consistent with this approximate relationship.
Are these figures affected by the growth of the unlicensed offshore market?
Yes, indirectly. The UKGC statistics only capture activity at licensed operators, so any migration to unlicensed sites is invisible in the official numbers – but those bets are still happening and still affecting the underlying engagement with racing. Independent estimates suggest unlicensed operators now account for around 9% of UK online gambling activity, which represents a meaningful portion of activity that has exited the regulated reporting framework.
What the Numbers Together Tell You
The UK horse racing betting market remains substantial in absolute terms – £766.7m in remote GGY alone, before counting retail, plus a broader economic footprint supporting 85,000 jobs across the country. But the trajectory is concerning, and the divergence between holding-up GGY and falling turnover suggests the underlying engagement is contracting even as the bookmaker side of the equation remains profitable. For a punter, these are not abstract numbers. They are the structural conditions that shape the prices you take, the limits on your account, the frictions you encounter and the prize money funding the racing you’re betting on. The market still works; it is just under more pressure than it has been at any point in recent memory.
