   Direct gambling marketing, direct harm: A randomised experiment.

   Addiction (Abingdon, England) (Rockloff et al.)Published Mar 18, 2026Checked Oct 4, 2026

   “d accounts.InterventionParticipants were stratified by PGSI risk category, age group and gender and then randomly allocated either to an opt-out condition (n = 96), in which they opted out of direct marketing from their wagering operators and provided proof, or to a control condition (n = 131) that continued to receive direct marketing as usual.MeasurementsSeven EMA surveys were administered every 48 hours over a 14-day period during a high-volume betting season. Outcomes were self-reported number of bets placed, gambling expenditure (in Australian dollars, AUD) and short-term gambling harms in the previous 48 hours, assessed with a 10-item adapted Short Gambling Harm Screen (SGHS).FindingsThe opt-out group placed 23% fewer bets [B = -0.11, 95% confidence interval (CI) = -0.20, -0.03, P = 0.011], spent 39% less money (B = -0.53, 95% CI = -0.84, -0.21, P = 0.001) and reported 67% fewer short-term gambling harms (B = -0.22, 95% CI = -0.36, -0.07, P = 0.004) compared with the controls.ConclusionsOpting out of receiving direct marketing from wagering operators appears to be associated with statistically significantly fewer bets made, amount spent gambling and short-term gambling harms.”

   Sports sponsorship, gambling bans, and regulatory compliance: a systematic review.

   Frontiers in sports and active living (Obiol-Anaya et al.)Published Aug 6, 2026Checked Oct 4, 2026

   “IntroductionThis systematic review evaluates the impact of sports sponsorship bans and betting restrictions on marketing practices, regulatory compliance, and consumer behavior following global market liberalization.MethodsFollowing PRISMA guidelines and the SPICE framework, we searched five major academic databases for peer-reviewed literature from 2022 onwards, synthesizing 29 eligible studies evaluated via the Mixed Methods Appraisal Tool (MMAT).ResultsGambling sponsorship has expanded rapidly in professional sports over two decades. Comprehensive statutory bans significantly reduce marketing exposure and new gambling registrations, whereas partial or voluntary self-regulatory restrictions lead to marketing displacement and circumvention tactics such as sub-branding.DiscussionPartial and voluntary restrictions are insufficient to protect public health and sports integrity. Comprehensive statutory prohibitions covering primary and derivative proxy brands, supported by strong enforcement and alternative funding for sports organizations, are essential for effective policy implementation.”

   Regulatory Whack-a-mole: A Rapid Scoping Review of Gambling Marketing Restrictions and their (in)Effectiveness.

   Current addiction reports (Torrance et al.)Published Sep 17, 2026Checked Oct 4, 2026

   “(4) Inducement Restrictions yielded the strongest behavioural evidence, with sustained reductions in customer acquisition and money gambled, though operators restrategised by redirecting promotional effort towards retaining existing customers. (5) Platform-enforced measures curtailed on-platform content but not external gambling website traffic or underage exposure. (6) Comprehensive Bans were circumvented through alibi marketing, transitional exemptions, and reallocation of spend to unregulated, operator-owned media channels.SummaryRegulatory displacement was evident across all six categories. Operators consistently migrated marketing activity to less regulated channels, formats, and strategies following each restriction, mirroring the established regulatory trajectories of tobacco and alcohol marketing. Effective gambling marketing regulation requires statutory, comprehensive, and future-proof frameworks rather than the voluntary, circumventable, and reactive approaches evaluated in this review.Supplementary informationThe online version contains supplementary material available at https://doi.org/10.1007/s40429-026-00793-5.”

   A narrative review of qualitative studies exploring the normalization of gambling for youth and younger adults.

   Health promotion international (Murray et al.)Published Sep 1, 2026Checked Oct 4, 2026

   “First, gambling was socially constructed as a normative activity through early family exposure and peer group practices, where participation could both encourage and discourage engagement. Second, exposure to gambling advertising, particularly through sport, was a pervasive driver of normalization, framing gambling as entertaining, glamorous, and overwhelmingly positive. Third, digital access via smartphones, apps, and online platforms further embedded gambling into daily life, enabling engagement in previously restricted spaces and facilitating peer-to-peer participation. Finally, youth and younger adults articulated strategies to counter the normalization of gambling, emphasizing structural and regulatory approaches, including stricter controls on advertising, counter-marketing campaigns, education, and youth participation in policy development. Policy action is needed to tackle the influence of a range of determinants of gambling normalization, with a particular focus on how commercial drivers and political responses impact youth and younger adults in specific sociocultural settings and contexts.”

   Online gambling as a public health and regulatory challenge: moving beyond individual responsibility.

   Frontiers in public health (Izquierdo-Condoy et al.)Published May 20, 2026Checked Oct 4, 2026

   “Recent evidence shows that online gambling is associated with gambling disorder, depression, anxiety, suicidality, financial distress, family conflict, and harms to affected others, although much of the current literature remains cross-sectional and heterogeneous. We further examine how vulnerabilities are unequally distributed across age, sex, socioeconomic position, and regional regulatory context. To move beyond a purely descriptive account, we compare recent policy responses across jurisdictions, including stake limits and a statutory levy in Great Britain, restrictive advertising rules in Belgium, and new federal controls in Brazil. These examples suggest that effective harm reduction requires more than self-regulation or individual responsibility messaging. A precautionary public health approach should include restrictions on advertising and inducements, binding deposit or loss limits, centralized exclusion systems, robust age verification, financial safeguards, and insulation of research and policymaking from industry influence.”

   Gambling advertising (Wikipedia)

   WikipediaPublished Sep 29, 2026Checked Oct 4, 2026

   “Gambling advertising is the promotion of gambling by casinos, lotteries, video games, bookmakers or other organisations that provide the opportunity to make bets. It is usually conducted through a variety of media or through sponsorship deals, particularly with sporting events or people. Although not as highly regulated as tobacco advertising and alcohol advertising, in many countries there are strict laws about the way in which such services can be marketed. Gaming operators often sponsor sporting events, sportspeople or television coverage. For example, Bet365 sponsor snooker players and the Channel 4 coverage of The 2005 Ashes was sponsored by Betfair, both being online betting sites. In other instances, they will do stunts to get public attention. For example, many professional boxers have been sponsored by GoldenPalace.com, and sport temporary Golden Palace tattoos on their bodies. To get around advertising restrictions, some online poker companies advertise free-play sites, like PartyPoker.net and PokerStars.net, and sometimes even call these free sites "poker schools". These sites restrict access to those of legal age, even though it is not required.”
