KSA data show Dutch illegal betting market grows more than 57%
The Netherlands’ gambling regulator, KSA, reported that the illegal market grew by more than 57% after the tax rate rose to 34.2%, according to the report. It also said licensed operators’ share of revenue fell from 51% to 49% at the start of 2025, while gross gambling revenue dropped 16%.
The reported revenue-share decline and market growth highlight how Dutch tax conditions coincide with changes in licensed operators’ position.
