The second highest earning country is the United Kingdom, with projected revenue of $13.78 billion in 2024. The UK has the second-highest number of gamblers, with 27.9% of the population having gambled online, even though the UK is projected to have the fourth-lowest increase in revenue this year, with a 7.4% increase expected in 2024. It is also estimated that the UK will have the fourth-lowest rate of revenue increase between 2024 and 2028, with a rate of 3.84%.

Emiko Matsuda, Editor-in-Chief of 日本のオンラインカジノ, commented on the findings: “The surge in online gambling can be attributed to a variety of factors such as the pandemic, which meant many bettors transitioned from wagering on sports to online gambling, and the data suggests that this shift is permanent.

“Online gambling is prohibited in Japan, yet the data shows that online gambling is pervasive in Japanese society despite the law.

“The Act on the Development of Specified Integrated Resort Districts was passed in 2018, which aims to authorize the establishment of gambling facilities within specified zones across the nation. The first legal casino is due to open in 2029 in Osaka. However, a 2021 study, commissioned by the Osaka Prefectural Government, showed that 2.2% of the total population were grappling with gambling addiction, suggesting that gambling is already a popular pastime for many despite the law.”


61 countries with available data were included in the study.

The study analyzed the following:

  • Revenue in the Online Gambling market projected to be reached by 2024.
  • Year-over-year percentage change in revenue between 2023 and 2024.
  • User penetration projected for 2024, which shows the number of customers who have made at least one online purchase within the past 12 months.
  • The annual revenue growth rate (2024–2028).

The countries were then ranked from highest to lowest based on the revenue projected to be made in 2024.
