The real surprising part is that Anthropic is also negligible (according to this article) in Germany. It's all OpenAI. But I didn't dare to change the title that much.
Besides a few software devs about zero people I talk to (I'm in the EU) have ever heard of Claude / Anthropic. It's all Gemini (the default in Google), ChatGPT (pretty much a verb for "I ask questions to an AI") and some have Grok subscriptions (!).
When I mention Anthropic and/or Claude people have zero clue what I'm talking about.
