Scalable Capital is opening its investment platform to ChatGPT, Claude and Grok, allowing European customers to analyze portfolios, set up savings plans and prepare trades through prompts. The Munich-based bank says it is the first bank in Europe to connect its platform to major AI assistants through the Model Context Protocol (MCP), although users must approve trades and savings plans before execution and cannot use the assistants to make payments or withdraw funds. Scalable has more than 1 million customers and more than €60 billion in client assets, primarily in Germany and Austria, with operations also in Italy, Spain, France and the Netherlands. The service comes as research suggests AI models can identify market direction but may take excessive risks when deciding position sizes.
