Executive Summary
The Swiss Competition Commission (WEKO) warns of competition risks posed by artificial intelligence and announced enhanced monitoring. In 2025, WEKO conducted 18 investigations, 8 preliminary clarifications, and 43 market observations. It processed 34 corporate mergers and closed eight major proceedings – including cases in ticketing, broadband, travel, construction, and healthcare. The authority prohibited three behaviors and sanctioned violations, but also approved the Hotelplan-DERTOUR merger.

WEKO signals heightened vigilance in 2026 toward AI-driven competition risks – a strategic signal for tech companies and regulators across Europe. The core dilemma is temporal: Interventions that are too early could stifle innovation, while measures that are too late entrench monopolistic structures. The authority positions itself as a proactive observer, not a reactive sanctioning apparatus. This reflects pressure on competition authorities worldwide to anticipate AI-driven market power before it becomes entrenched.
Detailed Summary
WEKO identifies two central AI risks: algorithmic collusion (price coordination without direct contact) and obstruction strategies by market-dominant enterprises. While AI can enable efficiency gains, faster innovation, and lower barriers to market entry, these effects depend heavily on market structure, access to resources, and the behavior of dominant actors. In sectors applying AI, significant concentration risks exist – a structural problem exacerbated by algorithmic pricing.
The 2025 balance sheet shows intensive activity: Beyond investigations and merger control, WEKO submitted statements in approximately 350 inter-agency consultations and public comment procedures. The eight completed major proceedings covered diverse sectors (ticketing, broadband, tourism, construction, retail, card fees, automotive, healthcare), indicating broad competition problems. The prohibition of three behaviors and the rejection or conditioning of mergers demonstrate enforcement-oriented practice, while the amicable settlement of one proceeding without fines signals flexibility.
Key Findings
- WEKO views AI as a structural competition risk, particularly through algorithmic price coordination and market concentration.
- Regulatory timing is critical: Interventions that are too early inhibit innovation, those that are too late entrench monopolies.
- WEKO positions itself as a forward-looking observer, not a reactor – focusing on market structures, not only individual violations.
- 2025 was a year of high activity (18 investigations, 34 merger reviews, 350 statements), suggesting pressure and resource constraints.
Critical Questions
Data Quality: What indicators does WEKO use for early detection of algorithmic collusion? Are these methods empirically validated, or based on theoretical models?
Conflicts of Interest: How does WEKO ensure that its observation role does not lead to regulatory overreaction that inhibits tech innovation in Switzerland?
Causality: To what extent are observed concentration risks in AI sectors caused by AI itself, versus by upstream market structures (e.g., data monopolies, scaling effects)?
Feasibility: How can WEKO prove and sanction algorithmic price coordination when algorithms act "autonomously" and no direct cartel agreement exists?
Timing Mechanics: What concrete thresholds or indicators trigger the transition from "observation" to "investigation"?
Resources: Do 350 statements and 43 market observations suggest capacity limits that jeopardize rapid response to AI risks?
