Illegal Online Gambling Overtakes Legal Market in the Netherlands

In the Netherlands, the illegal online gambling segment has overtaken the legal market, according to the 2025 annual report from the Gambling Authority Kansspelautoriteit (KSA).

The report highlights several key figures:

Market size and segment share

  • €4.3bn – total legal gambling market (YoY unchanged)
  • €617m (KSA estimate) and €600m – illegal and legal online segments in H1 2025
  • 51% – 49% – share of the legal segment in GGR from end of 2024 to early 2025 ~94% – share of players using only licensed operators

Operator fines in 2025

  • €8.6m – 5 fines for licensed operators for player protection breaches (vs €800k / 2 fines in 2024)
  • €31.2m – 4 fines for illegal operators (vs €4.1m in 2024), including penalties based on estimated GGR using a new Google search-based methodology
  • 10% – legal cap on fines as a percentage of global GGR, with discussions ongoing to increase it

Self-exclusion register (Cruks)

  • ~85k -109k — registered users in one year
  • 380 – forced registrations initiated by operators (vs 97 in 2024)
  • 17%-29% and 41%- 50% – awareness growth of the Gokstop campaign among frequent and problem gamblers

Sports sponsorship ban

  • From 1 July 2025 – full ban on sports sponsorship by online operators
  • No major violations recorded after implementation

“Disconnect” enforcement programme (launched 2025)

  • 4 focus areas – marketing, B2B, payments, internet
  • Since August 2025, almost no illegal casino ads on Google (KSA claim)
  • 50,000+ illegal ads monthly on social media, 800 complaints (vs 219 in 2024)
  • 4 influencers sanctioned over illegal gambling promotion
  • Cooperation with .nl registry blocked access to part of illegal affiliate infrastructure

Regulator finances

  • €11.1m – annual result
  • €20.3m – collected regulatory fees vs €27.7m planned
  • Decline linked to tighter limits and higher gambling tax.

KSA noted that stricter player protection rules may have contributed to some migration toward illegal operators and a decline in the legal GGR share.

The regulator continues to expand enforcement via its “Disconnect” programme and is discussing higher penalty limits above 10% of global GGR with the Ministry of Justice.
