The United Nations has warned that the rapid adoption of AI in advertising could deepen a global information integrity crisis. With worldwide advertising spending now exceeding $1 trillion annually, concerns are growing over how automated systems influence what users see, trust, and engage with online.
A briefing by the Department of Global Communications and the Conscious Advertising Network places advertising at the centre of the digital information ecosystem. It argues that advertising helps fund and shape the systems that influence what people see and believe, while AI-driven tools are increasingly being used in media buying and content generation in ways that can amplify disinformation, hate speech, and opaque decision-making.
Transparency gaps in AI advertising systems are also raising concerns over fraud, inefficiency, and declining trust in digital platforms. The report warns that these pressures can weaken independent journalism and reduce advertising effectiveness as confidence in online environments continues to erode.
UN officials and industry representatives are calling for stronger governance, clearer oversight of AI supply chains, and closer cooperation between regulators, advertisers, and civil society. The core message is that without stronger guardrails, AI may accelerate the breakdown of information ecosystem integrity rather than simply improve commercial performance.
Why does it matter?
AI is becoming embedded in systems that shape the online flow of information, which means advertising is no longer only a commercial mechanism but also a force affecting public perception and trust. As automation expands without clear oversight, risks can spread beyond brand safety into disinformation, media sustainability, and democratic discourse.
