Online slots generated about £4.8 billion in gross gambling yield in Great Britain in 2025–26.
The Gambling Commission's annual industry statistics, published on 17 September 2026, show that online slots generated approximately £4.8 billion in gross gambling yield (GGY) between April 2025 and March 2026.
Online casino revenue reached £5.7 billion, while Great Britain's wider gambling industry generated £17.5 billion, including reported lotteries.
GGY measures gambling revenue after winnings and relevant prizes have been deducted from stakes and associated receipts. It is not the total amount wagered or the profit operators retain after expenses and taxes.
Online Slots Account for 84% of Digital Casino Revenue
The latest figures show that online slot games accounted for most of Great Britain's regulated online casino GGY. Slots generated approximately £4.79 billion in GGY during the financial year ending March 2026, representing around 84% of total remote casino revenue. Other online casino products accounted for the remaining share.
Online slots GGY increased by approximately 15.5% compared with the previous financial year. This outpaced the growth of the remote casino sector overall, which expanded by roughly 14.8%.
The concentration is financially significant because changes in slots revenue have a substantial influence on the performance of the wider digital casino sector.
The Gambling Commission also distinguishes remote casino revenue from online sports betting and bingo, which are reported separately.
Online Gambling Growth Outpaces the Wider Market
Great Britain's remote casino, betting and bingo sector generated approximately £8.3 billion in GGY during 2025–26, an increase of 6.9% from the previous financial year. By comparison, land-based gambling sectors, including arcades, betting shops, bingo halls and casinos, generated approximately £4.9 billion, representing growth of 1.1%.
These figures demonstrate the stronger revenue growth recorded across remote gambling activities, although performance differed considerably between individual categories.
Remote betting contributed approximately £2.4 billion, while remote bingo generated £147.8 million. Online casino products accounted for the largest share of the remote sector's revenue.
Performance across physical gambling venues was similarly mixed. Non-remote betting GGY declined by 3.3%, while land-based bingo revenue increased by 8.2% and arcade revenue rose by 10.7%. Meanwhile, the number of licensed betting shops fell by 3.6% to 5,617.
The contrasting results underline the importance of examining individual gambling categories rather than treating industry-wide revenue growth as evidence of uniform expansion.
Stake Limits Applied During the Reporting Year; Higher Duty Followed
The latest industry figures also cover a period of significant regulatory changes affecting online slots.
Great Britain introduced a £5 maximum stake per online slots game cycle for all adults on 9 April 2025. From 21 May 2025, the maximum was reduced to £2 for players aged 18–24, while remaining £5 for those aged 25 and over.
Both limits took effect during the financial year covered by the Gambling Commission's latest annual statistics.
A separate taxation change followed on 1 April 2026, when Remote Gaming Duty increased from 21% to 40%. The higher duty applies to remote gaming activities, including online slots and other casino games. However, it came into effect after the March 2026 reporting period ended.
This distinction is important when interpreting the figures. Although slots revenue increased during the introduction of stake limits, the annual statistics alone do not establish how those restrictions influenced market performance.
The reporting period ended before the higher duty took effect, and GGY does not measure operators' tax bills or net profits.
Future releases covering April 2026 onwards will show how reported gambling yield develops after the duty increase. Those figures alone will not establish its effect on revenue or profitability.
What the Figures Mean for Britain's Gambling Market
With approximately £4.8 billion in annual GGY, online slots accounted for the substantial majority of Great Britain's digital casino revenue in 2025–26.
The Gambling Commission's findings highlight stronger growth in remote gambling than in land-based sectors, alongside considerable differences between individual gambling categories.
Future industry reports will help establish whether these revenue patterns continue under the newer stake limits and taxation arrangements.
