Horse Racing Remains the UK’s Second-Largest Betting Sport — But Turnover Is Falling
Horse racing has been the backbone of British betting for over a century. From the high street bookmaker to the exchange trading floor, racing built the infrastructure that every other sport now uses. And yet the numbers tell a story of a market under structural pressure — still enormous in absolute terms, but shrinking in ways that matter to everyone who bets on the sport.
Online horse racing betting generated £766.7 million in gross gambling yield during the year to March 2025, making racing the second-largest online betting sport in the UK behind football at £1.3 billion. Those figures come from the Gambling Commission’s Industry Statistics report and represent the amount bookmakers retain after paying out winning bets — the industry’s revenue, not the total amount wagered. For context, the total UK gambling market produced £16.8 billion in GGY over the same period, a 7.3% increase year on year, with remote online operations accounting for £7.8 billion — 46% of the entire market.
Racing’s share of that total is substantial but declining relative to other verticals, and the turnover data paints an even more concerning picture.
GGY and Turnover: Where the Numbers Stand in 2025
There’s an important distinction between GGY and turnover that casual observers often miss. GGY — gross gambling yield — is revenue: the money bookmakers keep. Turnover is the total amount wagered by bettors. A healthy betting market has high turnover relative to GGY because that means bettors are recycling their money through multiple bets, which indicates engagement, liquidity, and a functioning market. When turnover falls but GGY stays flat or rises, it means bookmakers are extracting a higher margin from a smaller pool of activity — good for the bookmaker’s quarterly report, less good for the long-term health of the market.
That’s precisely what’s happening. Total betting turnover on UK horse racing fell 4.3% in 2025, and the cumulative decline since 2023 has reached 10.3%. Over a decade, the trajectory is clear: more money flowing through fewer bets at higher margins. The market that bettors operate in today is structurally different from the market of even five years ago — tighter odds on average, more aggressive account restrictions, and a regulatory environment that has pushed a measurable segment of activity into the unlicensed market.
The UK sports betting and horse racing market was valued at approximately £3.7 billion in 2026 by industry analysts IBISWorld, encompassing both online and retail channels. That valuation positions racing as a major commercial operation — but one whose growth rate is lagging behind the broader gambling market, which has been buoyed by the expansion of online casino products, in-play football betting, and emerging verticals like esports.
For bettors, falling turnover has a direct practical consequence: exchange liquidity. Thinner markets mean less money available at any given price, wider spreads between back and lay, and greater difficulty getting matched at the odds you want — particularly on midweek racing and smaller meetings. The days when you could reliably get a four-figure bet matched at the best exchange price on a Tuesday afternoon handicap at Catterick are behind us for all but the most liquid markets.
Levy Board Funding: Record Collections, Declining Volumes
The Horserace Betting Levy Board collected a record £108.9 million in 2024/25, the highest figure since the levy system was reformed in 2017. That sounds like good news — and in isolation, it is. The levy funds prize money, integrity services, veterinary science, and the regulatory infrastructure that keeps British racing functioning. More levy money means more prize money, which attracts more owners, which maintains the horse population, which sustains the racing programme.
But the record collection masks a troubling dynamic. Louie French, then Conservative Shadow Minister for Sport and Gambling, warned that the rise in black market gambling should be a concern for all, calling it entirely predictable and urging the government to change course from its current regulatory trajectory. The levy is calculated as a percentage of bookmakers’ gross profit on racing, and the record collection partly reflects the fact that bookmakers’ margins on racing have been unusually high — meaning they’re keeping a larger share of a shrinking turnover pie.
Average betting turnover per race has declined by 8% over the 2024/25 period, by 15% compared to 2022/23, and by 19% compared to 2021/22. Those figures, cited by Alan Delmonte, then Chief Executive of the HBLB, quantify the erosion of betting activity at the race-by-race level. A race that generated £500,000 in turnover three years ago now generates roughly £405,000. The levy collects more because the margin on that £405,000 is higher, but the underlying activity — the number of bets, the number of bettors, the liquidity of the market — is contracting.
In 2026, the HBLB announced increased grant expenditure: an additional £4.4 million for prize money and £1.2 million for regulatory incentives, as part of a total funding package of £77.1 million. This investment is designed to support the sport through the current downturn, but it’s a short-term buffer rather than a structural solution to declining betting volumes.
Premier vs Core: The Two-Tier Market
One of the most significant trends in UK racing is the polarisation between Premier fixtures and Core fixtures. The BHA’s classification system divides the racing programme into Premier meetings — the big Saturday cards at major courses — and Core meetings — the everyday midweek and minor-course fixtures that make up the bulk of the schedule.
Average betting turnover per race at Premier fixtures rose 2.7% in 2025. At Core fixtures, it fell 8.6%. That divergence creates a two-tier market. Premier racing — Cheltenham, Ascot, York, Newmarket’s big meetings — attracts the television coverage, the public interest, and the betting volume that makes markets liquid and competitive. Core racing — Tuesday at Plumpton, Wednesday at Wolverhampton — sees thinner betting markets, smaller fields, and less media coverage.
For bettors, the polarisation has practical implications. The value landscape is different on a Premier Saturday than on a Core Tuesday. Premier markets are sharper — more professional money, tighter odds, more efficient pricing — which means finding value requires deeper analysis. Core markets are less efficient — fewer eyes on the race, less sophisticated pricing — which theoretically creates more opportunities for an informed bettor, but the thinner liquidity and smaller fields reduce the range of betting options available.
The horse population decline — 21,728 in training, down 2.3% — amplifies the polarisation. Fewer horses means smaller fields, particularly at Core meetings. Average field sizes on flat racing have dropped to 8.90, with jumps at 7.84. Premier fixtures buck the trend with an average of 11.02 on the flat and 9.41 over jumps, because owners and trainers concentrate their better horses at the bigger meetings where prize money and exposure justify the travel and entry costs.
Total prize money hit a record £194.7 million in 2025, but the distribution reinforces the divide. Racecourse contributions to prize money reached £103.4 million, with the HBLB adding £63.2 million. The biggest purses go to the biggest meetings, which attracts the best horses and the most betting interest — a virtuous cycle for Premier racing and a challenging spiral for the rest of the programme.
