Online Casino Added More GGY Than Britain’s Whole Gambling Market Grew
Online casino added £736 million to Great Britain’s gambling yield in 2025/26. The increase across the entire gambling industry was £728 million. Both figures appear in the Gambling Commission’s published text of Sarah Gardner’s November 5 CEO briefing, released on November 6. One part of the market contributed more growth than the net increase for the whole.
That is possible when growth in one category is offset elsewhere. It does not mean online casino accounted for more than the entire market, nor does £736 million describe its total annual revenue. It is the increase over the previous financial year.
Start with the £17.5 billion total
Gardner, the Commission’s acting chief executive, puts total gross gambling yield at £17.5 billion for 2025/26, up 4.4%. Remote casino, betting and bingo together generated £8.3 billion, an increase of 6.9%. That combined remote figure is broader than online casino alone.
Keep those labels attached to the numbers. Comparing the £736 million online-casino increase with the £8.3 billion remote total would mix a change with a level, and a single category with a group of activities. The speech’s more revealing comparison uses the two increases: online casino against the industry as a whole.
Gross gambling yield measures what operators retain from gambling after winnings are paid, before operating costs and other expenses. It is not the total amount staked. It is also not profit: a business still has wages, premises, energy and other costs to meet.
Land-based growth has its own divisions
The speech reports land-based GGY growth of 1.1%. Within that figure, adult gaming centres rose 11% and non-remote bingo rose 8%, while non-remote betting declined. Gardner describes casino growth as negligible.
A rise for land-based gambling overall therefore tells little about an individual shop, club or casino. Gardner explicitly warns that the headline figures do not tell the whole story, pointing to the cost pressures facing businesses. Higher GGY does not establish that margins improved.
The same care is needed with a company report. Our MGM Q3 results coverage separates room rates, revenue and same-store comparisons. Those are different measures and a different reporting period from this annual British market account; they cannot be substituted for one another simply because both describe gambling businesses.
Participation is another question
Gardner also reports that 47% of adults had gambled in the previous four weeks in the 2025 participation data, describing that measure as stable. That survey percentage counts people reporting activity. The GGY figures measure money retained by operators. A stable participation measure can sit alongside rising yield without either statistic being contradictory.
For the online-casino story, the useful result is the concentration of growth. The Commission’s £736 million and £728 million comparison shows how strongly that category influenced the annual total. It does not, by itself, supply an online-casino profit figure, a player spending average or an operator’s market share.
