World Cup Advertising and Ambush Marketing: Legal Boundaries for Businesses

Major sporting events generate audience, consumption, sponsorships, and commercial disputes on an exceptional scale. In Brazil, the FIFA World Cup carries particular economic relevance because it influences advertising campaigns, retail promotions, digital strategies, point-of-sale activations, and institutional initiatives across virtually every industry sector. The legal challenge lies in legitimately capitalizing on public interest without infringing trademarks, official symbols, media rights, or sponsorship rights. In this context, ambush marketing has ceased to be a concern exclusive to large brands and has become part of the compliance, governance, and risk management agenda of any business seeking to promote products or services during high-profile sporting competitions.

The central point is to understand that Brazilian law does not prohibit campaigns inspired by football, fan culture, or the spirit of national celebration. A company may engage with generic themes, use creative language, and explore the cultural context of the event, provided it does not create the impression that it is an official sponsor, partner, licensee, or supporter of the competition, FIFA, the CBF (Confederação Brasileira de Futebol, the Brazilian Football Confederation), or a national team. The boundary between lawful advertising and irregular advertising does not lie in mentioning football, but in how the message is constructed, in the overall visual presentation, in the choice of words, in the use of images, in proximity to official symbols, and in the perception that the average consumer may form.

Ambush marketing occurs when a company seeks to capture the visibility of an event without acquiring the corresponding commercial rights. The practice may take the form of association, where the campaign suggests a non-existent official connection, or intrusion, where brands, products, services, or promotional activities appear without authorization at event venues or during broadcasts. The Lei Geral do Esporte (General Sports Act), Law No. 14,597/2023, classified these conducts under Articles 170 and 171, providing for a penalty of detention from three months to one year or a fine when the purpose is to obtain economic or advertising advantage. Articles 168 and 169 are also relevant, as they address the unauthorized reproduction, imitation, sale, or commercial display of symbols owned by sports organizations.

Beyond the General Sports Act, the analysis must consider the Lei da Propriedade Industrial (Industrial Property Act), Law No. 9,279/1996, particularly the rules on trademark protection and suppression of unfair competition; the Lei de Direitos Autorais (Copyright Act), Law No. 9,610/1998; the Civil Code, regarding abuse of rights and civil liability; and the Código de Defesa do Consumidor (Consumer Protection Code), where communications may mislead the public. The Código Brasileiro de Autorregulamentação Publicitária (Brazilian Advertising Self-Regulation Code) is also important, as it guides ethical advertising conduct and may serve as a basis for challenges before the CONAR (Conselho Nacional de Autorregulamentação Publicitária, the Brazilian National Advertising Self-Regulation Council). Accordingly, an irregular campaign may result in cease-and-desist letters, mandatory withdrawal of advertising materials, loss of media investment, damages, product seizure, reputational harm, and, in specific circumstances, criminal liability.

FIFA's intellectual property guidelines for the 2026 World Cup reinforce this logic by stating that only rights holders may commercially exploit the official intellectual property. Protected assets include official names, logos, emblems, trophies, slogans, mascots, posters, typefaces, official hashtags, match schedules, and all other elements capable of identifying the tournament. FIFA permits editorial, journalistic, informational, or descriptive uses, but distinguishes these from commercial exploitation. For businesses, greater caution is required, as a sponsored post, a prize promotion, a themed window display, a domain name, a landing page, or an influencer campaign may be interpreted as an unauthorized commercial association if it uses official signs or implies authorization.

Brazilian experience demonstrates that prevention is increasingly critical. During the 2014 World Cup, the Lei Geral da Copa (General World Cup Act) created a temporary protection regime for FIFA's commercial rights. With the General Sports Act, part of that framework became a permanent feature of the sports law landscape. For the FIFA Women's World Cup 2027, to be held in Brazil, Law No. 15,421/2026 established a special regime for the protection of intellectual property, media rights, and marketing rights, and also provides for commercial exclusion zones around official venues and event-related spaces. The regulatory trend is clear: major sporting events will require advance legal planning, particularly for fast-circulating digital campaigns.

On the case law front, although not every precedent deals directly with the World Cup, the Superior Tribunal de Justiça (STJ, Brazil's highest court for non-constitutional matters) offers useful parameters for businesses. The STJ has consistently held that trademark protection exists not only to preserve the rights holder's financial interests but also to prevent consumer confusion, wrongful diversion of clientele, and parasitic economic gain. In rulings involving trademarks, counterfeiting, and trade dress (conjunto-imagem), such as Precedent No. 950 (Tema 950) and special appeals concerning the improper use of distinctive signs, the Court recognizes that unfair competition may arise even where the irregularity is not limited to the literal copying of a trademark. This reasoning is essential in sports marketing, as apparently creative campaigns may be challenged when they rely sufficiently on another party's goodwill to generate an undue association.

For business owners and managers, the key takeaway is that the risk is not limited to the use of logos. Elements such as official tournament names, mascots, images of the trophy, uniforms bearing official emblems, official hashtags, event tickets used as promotional prizes, match footage, broadcast excerpts, similar visual identities, and statements such as 'World Cup sponsor' or 'official promotion' all require prior authorization. Caution is also warranted regarding references to the Brazilian national team and individual athletes, as rights of the CBF, image rights, sponsorship agreements, and specific restrictions assumed by players, clubs, or sports entities may be implicated.

This does not mean that companies should distance themselves from the sporting calendar. The safest strategy is to build campaigns around generic elements such as football, fan spirit, celebration, national colors used without reproduction of official emblems, creative expressions without protected designations, and original visual materials. Broad terms, narratives of unity, promotions linked to customer performance, or internal experiences may be lawful when they do not lead consumers to believe there is an official connection. The practical question that should guide any legal review is straightforward: could the public understand that the brand has received authorization, is sponsoring the event, or is part of the official ecosystem of the competition? If the answer is yes or uncertain, the campaign must be revised.

Another important consideration involves contracts with agencies, influencers, audiovisual producers, franchisees, and commercial partners. Liability for an irregular advertising piece may extend to more than one party in the chain. For this reason, contracts should include obligations to respect intellectual property, require prior approval of content, establish a duty to remove materials immediately upon challenge, set rules on the use of generative artificial intelligence, assign responsibility for image banks, address music licensing, require authorization from individuals depicted, and prohibit the use of official assets without permission. For national campaigns, it is advisable that the legal team review not only the final creative piece but also scripts, captions, promotion names, contest mechanics, paid media, influencer content, and point-of-sale materials.

Internal governance must transform this subject into a structured procedure rather than an improvised response. An efficient workflow includes mapping protected assets, developing a risk matrix by campaign type, pre-validating advertising claims, reviewing social media content, training marketing and customer-facing teams, preserving evidence of approvals, and establishing a response plan for cease-and-desist notices. This approach reduces the likelihood of urgent campaign takedowns, avoids reputational costs, and demonstrates good faith should a challenge arise from a sports entity, official sponsor, or self-regulatory body.

The World Cup creates genuine business communication opportunities, but it also exposes companies to significant legal risks when advertising creativity exceeds the boundaries of free enterprise and encroaches on the appropriation of another party's reputation. The balance lies in leveraging the cultural context of football without exploiting protected assets, without implying an official connection, and without misleading consumers. Brazilian legislation has evolved to treat ambush marketing with greater rigor, and the trend is for sports organizations, rights holders, and sponsors to act in an increasingly preventive manner, particularly in the digital environment.

For businesses, the best response is strategic: plan campaigns in advance, conduct legal review of creative concepts before publication, document all authorizations, and align agencies and partners accordingly. Preventive legal counsel, when integrated into marketing and corporate governance, should not be seen as a barrier to creativity but as an instrument for protecting investments, reputation, and business continuity.
