Why Some Jurisdictions Ban Celebrity Endorsements for Casinos

The brief
The question of celebrity endorsement in gambling has never been straightforward in democratic societies, but it has become acute now that the marketing stakes have risen to match the gambling stakes. What began as self-regulation has evolved into formal prohibition across several key jurisdictions, and the reasons reveal something uncomfortable about the relationship between entertainment and risk.
The United Kingdom was first to address this directly. In 2014, the Advertising Standards Authority began flagging celebrity gambling advertisements that targeted under-25s, even obliquely. By 2020, the UK Government's Department for Digital, Culture, Media and Sport had proposed formal restrictions. These became law in 2021: no betting advertisements featuring celebrities or licensed characters could be broadcast during children's programming, and no celebrity could appear in gambling advertisements without declaring their financial interest prominently.
Ireland followed a similar trajectory. In 2017, the Broadcasting Authority of Ireland issued guidelines restricting celebrity involvement in gambling advertisements. The Irish approach was stricter in one respect: it banned celebrities who had significant followings among under-18s from appearing in any gambling advertisement, even after watershed hours.
The Underlying Logic
The regulations rest on two pillars. First, the evidence that celebrity endorsement disproportionately influences younger viewers, who have less developed risk assessment capacity. Second, the observation that celebrities create perceived legitimacy even when they have no expertise in the product. A footballer endorsing a sportsbook creates implicit endorsement of the sportsbook itself, not merely awareness of it.
European regulators distinguished between two types of celebrity involvement. A celebrity who appears in an advertisement is making a financial endorsement and should be regulated strictly. A celebrity who merely owns equity in a gambling company without appearing in marketing is a business matter, not an advertising matter. Only a few jurisdictions extended regulations to silent financial interests.
The Enforcement Problem
Enforcement has proven uneven. The United Kingdom has issued fines to betting operators whose celebrity advertising breached standards. The largest was 17 million pounds against Entain in 2023 for breaches across multiple brands. This suggests the regulations have teeth.
Yet the deeper issue remains unresolved. Celebrities operate across borders. A footballer who cannot endorse gambling in the UK can endorse it from a Spanish platform to British viewers. The regulations, in other words, impose constraints on domestic operators but do not eliminate celebrity gambling marketing. They simply redirect it to less regulated channels. This is called substitution risk by policy analysts, and nobody has yet solved it.
