Executive Summary

The Swiss Competition Commission (COMCO) opened two formal investigations on 30 April 2026. It suspects three travel operators and nearly all Swiss online casinos of coordinating their search engine advertising. Specifically, the companies are alleged to have agreed not to bid on their competitors' keywords. This "keyword bidding" cartel could have distorted competition and harmed consumers by making price comparisons more difficult. All accused companies are presumed innocent pending further investigation.

The investigations mark an escalation in cartel enforcement in the digital advertising platform sector. While traditional cartels operate through direct price-fixing, these suspected cases employ subtler mechanisms: companies are alleged to have silently coordinated their search engine advertising to avoid price competition. The cases demonstrate that classical cartel logic remains effective even in highly digitalized markets – with direct consequences for consumer prices and market transparency.

Detailed Summary

The cartel proceedings are based on several voluntary disclosures submitted to COMCO. In these disclosures, companies voluntarily reveal their own cartel participation to benefit from reduced penalties – a mechanism that is central to many cartel proceedings.

In the travel industry case, three package tour operators allegedly agreed not to bid on their competitors' brand keywords. In keyword bidding, companies pay search engine operators to display their ads when users search for specific terms. Refraining from mutual bidding reduces visibility and price pressure – consumers see fewer alternatives and find it harder to compare offers.

The online casino investigation covers nearly the entire Swiss market. This suggests industry-wide coordination rather than just bilateral agreements. Such comprehensive cartels are particularly serious under cartel law and demonstrate systematic competition violations.

COMCO is examining whether these agreements constitute an "impermissible agreement with anti-competitive and consumer-damaging effects" – the classic cartel definition under Swiss cartel law. Potential sanctions range up to 10% of the Swiss annual turnover of affected companies.

Key Findings

  • COMCO is pursuing digital cartels in two strategically important consumer markets (travel, gambling)
  • Search engine advertising agreements are difficult to detect but effective: they reduce price competition without explicit price-fixing
  • Voluntary disclosures enable COMCO to uncover cartels that would otherwise remain hidden
  • The investigations involve different market concentrations: 3 travel operators vs. nearly all online casinos

Critical Questions

  1. Evidence Quality: What concrete communication protocols or transaction data prove the agreements? Are voluntary disclosures alone sufficient evidence, or is independent market data also used?

  2. Conflicts of Interest: Do voluntary disclosers benefit from penalty reductions when they implicate competitors? Could this lead to false or exaggerated allegations?

  3. Causality: How is it proven that refraining from keyword bidding actually distorted search results? Could other factors (algorithms, budgets) explain the observed patterns?

  4. Enforceability: How can COMCO preventively detect such agreements in the future? Are search engine operators required to report suspicious bidding patterns?

  5. Market Consequences: Will penalties be returned to consumers, or will they remain in state coffers?
