Dutch regulated gambling captured 59% of market revenue in 2025 as Ksa flags heavy losses on illegal sites

The Netherlands’ licensed online gambling market took 59% of total gross gaming yield (BSR) in 2025, up from 54% the year before, according to Kansspelautoriteit’s (Ksa) annual report and its semi-annual report for the first half of 2026. The regulator’s numbers matter for PSPs because they show both where spend is flowing and how much revenue still sits outside the licensed stack.

1. In the first half of 2026, licensed operators generated around €670 million ($750 million) in BSR, or roughly €110 million a month, with the market up about 11% versus the previous six months. The Ksa said the licensed market had regained momentum after the second half of 2025.
2. Casino games played against the house accounted for about 73% of total revenue, or €492 million. Sports betting made up around 24%, or €163 million, up from approximately 20% in the second half of 2025.
3. The regulator said the rise in sports betting and overall revenue may be linked to the men’s FIFA World Cup. Sports wagering moved more sharply from month to month than casino activity, and the report also recorded a clear increase in new accounts in June.
4. Across the half-year, 563,000 accounts were opened, compared with 529,000 in the previous six-month period. Licensed operators also reported an average of 1.48 million active accounts per month, up from 1.38 million in the second half of 2025.
5. Ksa’s estimate of the unlicensed market combines GfK panel data on participation with a Google Ads search-volume method. For the first half of 2026, the regulator estimated that around 20,000 people gambled exclusively with unlicensed operators each month, while another 10,000 used both licensed and unlicensed sites.

Here’s the catch: depending on the method used, the share of players using legal providers was estimated at between 94% and 97%, yet illegal-market players appear to account for a disproportionate share of revenue. The Ksa said that suggests those players may lose considerably more on average than customers on licensed platforms, while also noting that its illegal-market estimates remain subject to uncertainty and are still being refined.
