Turnover, GGY and the Levy: Where the Money Goes

Three metrics define the financial state of UK horse racing betting: turnover, gross gambling yield, and the Horserace Betting Levy.

Turnover is the total amount staked. The £8.73 billion figure for 2023/24, reported by the Gambling Commission and cited by the Racing Post, represents every pound bet on every horse race in Britain over the financial year. Two years earlier, that figure exceeded £10 billion. The drop — 16.3 per cent — is not explained by a single cause. It reflects a combination of affordability checks deterring higher-staking customers, a broader cost-of-living squeeze reducing discretionary spending, and the migration of some betting activity to unlicensed offshore operators who are not captured in official statistics.

The BHA’s own data confirmed the direction of travel. Its Racing Report for the full year 2026 showed overall betting turnover on horse racing falling a further 6.8 per cent year-on-year. The first quarter of 2026 was worse still: turnover on British racing dropped nine per cent compared to the same period in 2026, according to figures cited by BHA Director of Racing Richard Wayman.

Gross gambling yield — the amount bookmakers retain after paying out winning bets — tells a slightly different story. The Gambling Commission reported that GGY from remote horse racing betting was £766.7 million in the 2026/25 financial year, within a total remote betting GGY of £2.6 billion. Horse racing remains the second-largest sport for bookmaker revenue, behind football’s £1.3 billion. The GGY figure is more stable than turnover because bookmaker margins have widened — when fewer punters bet, firms adjust their overrounds and promotional spend to protect profitability. In practical terms, this means the average bettor is paying a higher implicit cost per bet than they were five years ago, even if the nominal odds look similar.

The Horserace Betting Levy Board collects a percentage of bookmaker profits on horse racing and redistributes the money back into the sport — funding prize money, veterinary science, racecourse improvements, and integrity services. According to the HBLB’s indicative figures for 2026/25, the Levy yield reached nearly £109 million — a record since the collection reforms of 2017 and the fourth consecutive year of increase. As Alan Delmonte, the Board’s Chief Executive, noted, this record came despite significant headwinds, reflecting the resilience of the levy mechanism even as underlying turnover declines.

The paradox of rising Levy income alongside falling turnover is explained by the GGY dynamics: bookmakers are retaining a larger share of a smaller total, and the Levy is calculated on profit, not on turnover. If the margin widens faster than turnover shrinks, the Levy grows. But this is not a sustainable trajectory. At some point, shrinking turnover will overwhelm margin expansion, and the Levy — and with it, the prize money and infrastructure it funds — will start to contract. The HBLB’s own report acknowledged this risk, noting that affordability checks were having a particular effect on higher-staking customers’ activity.

What This Means for the Punter on the Ground

Macro data can feel remote when you are studying a Chelmsford racecard at 5pm on a Tuesday. But the market-level trends have tangible consequences for everyday betting.

First, odds compression. As bookmakers protect margins in a shrinking market, the overround on individual races edges up. A race that might have been priced at 112 per cent in 2021 may now be priced at 118 per cent. The difference is invisible on any single bet, but across hundreds of bets over a season, it compounds into a measurable reduction in expected return. Shopping for the best price across multiple bookmakers — always important — becomes even more critical when the baseline margins are wider.

Second, account restrictions. As higher-staking customers are deterred by affordability checks, bookmakers increasingly depend on volume from recreational punters. Winning accounts — those that consistently take value from the market — face quicker restrictions: reduced maximum stakes, exclusion from promotional offers, or outright account closure. The nine per cent decline in Q1 2026 turnover suggests that the pool of active bettors is shrinking, which intensifies bookmakers’ focus on retaining the customers who lose and restricting those who win.

Third, the health of the racing product itself. Prize money is funded by the Levy and by racecourse revenues, both of which depend on a healthy betting market. If turnover continues to fall, the downstream effects — lower prize money, fewer fixtures, smaller fields — will eventually reach the racecard. Chelmsford’s competitive fields and generous Class 5/6 prize money exist because the economic ecosystem supports them. If that ecosystem weakens, the quality of the product weakens with it. The HBLB increased its grant expenditure supporting racing in 2026/25, including £66.9 million in prize money, £19.4 million for regulation and integrity, and further spending on welfare and training initiatives — but that spending is sustained by a Levy yield that relies on bookmaker profitability, which in turn relies on turnover that is moving in the wrong direction.

Fourth, the competitive landscape between bookmakers and exchanges shifts. As traditional bookmakers tighten margins and restrict accounts, some punters migrate to exchanges where the pricing is peer-to-peer and account restrictions are less common. Others move to unlicensed offshore operators — a trend the industry has warned about repeatedly but which remains difficult to quantify in official data. The net effect is a fragmentation of the market that makes the official turnover figures an increasingly incomplete picture of actual betting activity on British racing.

None of this means you should stop betting on horse racing. The market is large, liquid, and regulated. It means you should bet with your eyes open — aware that the economics behind the odds are shifting, that bookmaker behaviour is adapting to a contracting market, and that the value equation for punters is tighter than it was five years ago. The big picture behind every bet is not a reason for pessimism. It is a reason for discipline.
