From 1 July 2025 there will be complete ban on untargeted advertising of online gambling in the Netherlands.

That's a dramatic reversal in policy from just four years ago, when the market was first regulated.

The move will have a particularly significant impact in the Dutch sports world, where federations and clubs have benefited from intense sponsorship spending in the few years it has been legal.

But now that flow of money is coming to an end. What impact will the new rules have, in sport and more widely? And how will the betting operators adapt?
