EU opens proceedings against Booking.com over fraud and ad transparency
The European Commission has launched formal proceedings against Booking.com under the Digital Services Act (DSA), investigating whether the travel platform is doing enough to combat fraudulent listings and scams, including fake accommodations, identity theft, and phishing. The Commission will also scrutinize how Booking.com handles paid advertising, requiring clear labeling of sponsored results. According to Commission officials, Booking.com reported a 500% increase in fraud cases worldwide, with 1,072 reports in H1 2026 causing €82,000 in damages, a tenfold increase year-over-year. The investigation also examines the platform's data sharing practices, ensuring guest data is protected. EU Digital Commissioner Henna Virkkunen stressed that Europeans should be able to book holidays without fear of fraud. If violations are found, the Commission can impose fines up to 6% of global turnover.
This is a significant regulatory action under the DSA against a major travel platform, potentially setting precedents for how online platforms handle fraud and ad transparency, impacting the broader AdTech ecosystem.

Verve CEO Remco Westermann Predicts Huge Growth for LLM Advertising
In an interview, Verve CEO Remco Westermann discusses the impact of AI on consumer trust and advertising. He cites a Verve study showing that users distrust AI-generated content, especially younger demographics (45% of 18-24-year-olds), but trust AI as a personal advisor and shopping assistant. Westermann sees this trust as a huge opportunity for LLM-based advertising, predicting that chatbots will eventually become ad-funded, similar to Google's evolution. He advises brands on AI disclosure, emphasizing its importance for trust, but suggests it should not overshadow the message. For comparison platforms like Check24 or Booking.com, he advises integrating AI capabilities to offer personalized advice. He believes LLM advertising will be 'very big', with a mix of premium and programmatic ad sales, and notes that consumer offerings will rely more on advertising than B2B models.
