Does the EU AI Act apply to Swiss companies?
Yes, in two common situations. The EU AI Act applies to Swiss companies that place an AI system or general-purpose AI model on the EU market, and to companies whose AI system's output is used inside the EU - even if the system runs entirely on servers in Switzerland. No EU office or subsidiary is required.
When the AI Act reaches across the border
The AI Act (Regulation (EU) 2024/1689) is an EU law, but it was written with extraterritorial reach. According to Swiss law firm Lenz & Staehelin, it catches non-EU companies in two main scenarios:
You provide an AI system or general-purpose AI model to the EU market. "Placing on the market" includes making a product commercially available to EU users - for example a website or app aimed at EU customers, signalled by EU currencies, local delivery, or targeted advertising.
Your AI system's output is used in the EU. Even a system hosted and operated entirely in Switzerland can fall under the Act if its output is used there.
Using AI tools internally (as a customer of ChatGPT, Copilot and similar) is a different, lighter situation: most obligations sit with the provider, though transparency duties can still touch deployers.
The timeline as it stands in October 2026
The AI Act applies in phases:
February 2025: bans on prohibited practices took effect - manipulative or deceptive techniques, and most real-time remote biometric identification in public spaces.
2 August 2025: rules for general-purpose AI models, the governance framework (EU AI Office and AI Board) and the penalty regime took effect.
2 August 2026: transparency obligations (Article 50) started applying - AI-generated content must be identifiable, and people must be told when they interact with an AI system.
2 December 2027: rules for stand-alone high-risk AI systems now apply from this date, after the EU's AI Omnibus (formally adopted in October 2026) delayed them from the original August 2026 date.
2 August 2028: high-risk AI systems embedded in regulated products follow.
What it costs to get wrong
Fines can reach the higher of EUR 35 million or 7% of worldwide annual turnover for the most serious violations, enforced by national authorities in EU member states.
What Swiss companies should do now
Map where your AI systems and their outputs are used. If EU customers or users are in scope, assume the Act can apply.
Classify your systems: prohibited, high-risk, limited-risk (transparency), or minimal.
If you build on general-purpose models, collect the documentation your providers publish - you will need it for your own compliance file.
Watch the Swiss track: Switzerland is pursuing sector-specific regulation rather than a single AI law, but alignment pressure from the EU side is real.
