For web publishers, identifying a gambling ad is only the beginning of the compliance question. The same creative may be permitted when served for a licensed operator to an eligible audience in one market, but restricted or prohibited when it reaches a different jurisdiction, appears in the wrong context, or leads to a destination the operator is not authorized to promote.
This creates an important distinction between advertiser compliance and publisher exposure. Operators are responsible for complying with the rules that govern their campaigns, but publishers and other parties involved in distributing gambling ads can face their own obligations in some jurisdictions. Compliance can depend on who is advertising, where the user is located, who is likely to see the ad, where and when it appears, what the creative says, and where the click ultimately leads.
For web publishers and programmatic ad ops teams, the question is therefore not simply whether gambling ads are allowed. Treating the category as something to universally block or allow can either exclude permissible demand or allow non-compliant advertising to reach users. The more useful question is whether each impression remains compliant from the operator and audience behind it through to the creative, placement, and final destination. The rules governing those decisions vary by jurisdiction and continue to change. This article provides a reference point for understanding the regulatory landscape as of 2026 and should not be treated as a substitute for legal advice specific to the markets where a publisher operates.
The 2026 Shift: Publishers and Platforms Face Greater Responsibility
Recent regulatory changes show what greater publisher responsibility looks like in practice. New Zealand is one of the clearest recent examples. A renewed prohibition on advertising unlicensed online casino gambling took effect May 1, 2026, alongside new takedown powers and substantially higher penalties, reported at up to NZD 300,000 for individuals and NZD 5 million for companies and partnerships. The shift was already visible in enforcement: in September 2025, the Department of Internal Affairs fined four social media influencers and offshore operator Spinbet a combined NZD 125,000 for gambling advertising breaches. Croatia provides another publisher-specific example. Its April 2025 amendment, effective May 1, brought media-service providers, electronic-publication providers, advertising-service providers, and publishers within the scope of gambling advertising obligations, while also restricting when online ads can appear and links from electronic publications to gambling operator sites.
Elsewhere, the changes take different forms. Brazil introduced 2026 requirements for fixed-odds betting advertising, including verification of operator authorization and mandatory warnings. Kenya now requires gambling advertisements to receive regulatory approval at least seven days before airing, effective July 1, 2026. The details differ, but the direction is consistent: gambling ad compliance is becoming less about whether an advertiser belongs to an allowed category and more about whether a specific operator, audience, placement, and creative meet the requirements of the market receiving the impression.
Markets Where Gambling Advertising Is Effectively Off-Limits
New Zealand and Croatia show two ways gambling advertising can become effectively off-limits in practice. Other markets go further, either imposing near-total bans or prohibiting specific gambling categories and unauthorized operators. Belgium sits at the strictest end of that spectrum. Its 2023 Royal Decree introduced a near-total ban on gambling advertising across media, with limited exceptions such as advertising on a licensed operator’s own website. Italy‘s Dignity Decree similarly prohibits gambling and betting advertising across digital and other media, with the prohibition extending to the owner of the website or medium carrying the ad, not only the advertiser. Violations can result in a fine equal to 20% of the value of the advertising or sponsorship, with a minimum of €50,000 per violation, a penalty currently under constitutional review after a 2025 court referral questioning whether that minimum is proportionate for smaller publishers.
Other markets prohibit narrower categories rather than gambling advertising as a whole. Poland prohibits advertising and promotion of table games, card and dice games, mutual betting, and slot machines, making the type of gambling central to whether an ad can run. Türkiye criminalizes advertising or otherwise inducing participation in illegal sports betting and games of chance, with violations punishable by one to three years in prison. Japan‘s rules are narrower still: an amendment to the Basic Act on Measures Against Gambling Addiction, effective September 25, 2025, prohibits online promotion and solicitation directing people in Japan toward illegal online gambling, including sites and online content that route users to those services. The advertising provision itself does not carry a specific criminal penalty.
Markets Where the Operator’s License Determines Whether an Ad Can Run
A market permitting gambling advertising does not mean every operator serving into that market is authorized to advertise there. Hungary makes that distinction concrete and gives it real publisher-facing mechanics. Before a gambling ad is published, the advertiser must provide the advertising service provider or publisher with identifying information and evidence of authorization, and that documentation must be retained for five years. If the ad promotes unauthorized gambling, liability can extend jointly to the advertiser, advertising service provider, publisher, and person appearing in the ad. Penalties can reach ten times the financial benefit obtained from the unlawful advertising, with a minimum fine of HUF 10 million. Hungary’s regulator, SZTFH, also maintains a public list of blocked gambling websites.
Other markets draw the same licensed-versus-unlicensed line in different ways. Denmark restricts advertising to licensed operators and extends the prohibition on unlicensed gambling advertising to parties carrying those ads, including media publishers. Switzerland prohibits advertising gambling that is not licensed domestically, with violations carrying fines of up to CHF 500,000. Singapore makes advertising unlawful gambling an offence, while licensed operators must obtain approval from the Gambling Regulatory Authority before advertising. For publishers receiving programmatic demand across markets, the fact that an operator appears in the ad ecosystem is therefore not evidence that it is authorized to advertise in the market receiving the impression.
Other Rules That Can Make an Ad Non-Compliant
Authorization is not the end of the compliance check. Even when gambling advertising is permitted and the operator is properly licensed, a specific impression can still be restricted based on who receives it, where and when it appears, or what the creative itself contains.
The Netherlands makes the audience requirement particularly concrete. Licensed operators may not run untargeted gambling advertising, and targeted digital advertising must be structured so that at least 95% of the audience reached is aged 24 or older. Guidance published by the Dutch Gambling Authority in March 2026 further clarified requirements around third-party advertising, opt-out mechanisms, and demonstrating compliance. Ireland illustrates a different kind of restriction: under the Gambling Regulation Act 2024, gambling advertising on television and radio is prohibited between 5:30 a.m. and 9 p.m. The two approaches regulate different parts of delivery, but both show why operator authorization alone does not determine whether an impression is compliant.
Creative requirements add another layer. Brazil‘s 2026 rules require fixed-odds betting ads to display one of three mandatory warning messages occupying at least 10% of the ad area, horizontally and legibly, effective July 17, 2026. On the web, that requirement can become a delivery issue as well as a creative one. A warning designed to meet the requirement in one format may become too small or occupy a different proportion of the creative when rendered in another placement. A campaign approved at one size is therefore not automatically compliant at another.
Other markets regulate what gambling promotions can say or show. A UK rule effective January 19, 2026 prohibits promotional incentives that combine more than one gambling product, such as betting and casino, within the same offer. Portugal requires gambling advertising to be socially responsible, prohibits ads that feature or target minors, and bars associations between gambling brands and loan offers. These requirements make the creative itself another compliance checkpoint: an authorized operator serving an eligible audience can still deliver a non-compliant ad because of the offer, imagery, warning, or message it contains.
Why the United States, Canada, and Argentina Require Local Review
In the United States, there is no single comprehensive federal gambling advertising regime that replaces state-level rules, making the user’s state an important part of the compliance check. Colorado‘s SB26-131, effective August 12, 2026, prohibits sportsbooks and their marketing affiliates from targeting advertising at people under 21 or advertising through media where the majority of the audience is reasonably expected to be under 21, with advertising violations subject to penalties of up to $25,000. Connecticut regulates different parts of the same problem. Public Act No. 26-53, effective July 1, 2026, restricts AI-driven personalized betting promotions, gambling advertising at college and university athletic venues and affiliated digital platforms, and direct marketing to self-excluded players. The differences between two states illustrate why compliance cannot be determined from “US traffic” alone.
Canada similarly regulates gambling advertising at the provincial level, with Ontario providing one of the clearest examples. The Alcohol and Gaming Commission of Ontario permits inducements, bonuses, and credits to be advertised only on an operator’s own site or app or through direct marketing to people who have explicitly opted in, rather than through general public advertising. Since February 2024, Ontario’s standards have also prohibited active and retired athletes from appearing in iGaming advertising except where they exclusively promote responsible gambling, while restricting celebrities and other figures likely to appeal to minors. Breaches of the AGCO standards can carry administrative monetary penalties of up to CAD $200,000. An ad permitted elsewhere in Canada therefore cannot automatically be assumed to meet Ontario’s requirements.
In Argentina, online gambling is regulated at the provincial and local level rather than through a single nationwide advertising standard. Buenos Aires City‘s Ley 538 limits gambling advertising to basic factual information about the game, stakes, and determination of winnings, requires warnings about the consequences of problem gambling, and prohibits anyone under 18 from appearing in gambling advertising. For publishers distributing campaigns nationally, identifying an impression as originating in Argentina is therefore not geographically precise enough to establish which advertising rules apply.
What Web Publishers Should Verify When Allowing Gambling Advertising
Managing gambling advertising across programmatic inventory requires publishers to establish whether the relevant form of gambling advertising is permitted in the market and whether the operator behind the ad is authorized to advertise there. Where regulation varies below the national level, that check needs to account for the state, province, or local jurisdiction where the impression is served rather than relying on country-level targeting alone.
The next checks concern the impression itself. Publishers need to account for audience eligibility and placement or timing restrictions, as well as whether the ads appearing across their inventory meet local creative requirements. Depending on the market, those requirements can govern warnings and disclosures, promotional incentives, endorsers, or other elements of the ad. Where required, the information supporting compliance decisions also needs to be documented and retained.
Gambling advertising rules continue to change, making market-specific visibility and control increasingly important for publishers managing programmatic demand across jurisdictions. GeoEdge gives publishers real-time visibility into the ads appearing across their inventory, with granular controls to define which content, advertisers, and categories are permitted and block ads that violate those policies before they reach users. This allows publishers to apply different standards across markets without relying solely on demand partners to identify non-compliant advertising. Learn how GeoEdge helps publishers monitor and control gambling advertising across their inventory.
A note on accuracy: Gambling advertising law changes quickly, and jurisdictions frequently amend, delay, or overturn their own rules. This guide reflects the regulatory landscape at the time of publication and should not be treated as legal advice.
