German digital broker Scalable Capital is allowing customers to use artificial intelligence platforms such as ChatGPT and Claude to analyze their investment portfolios and execute trades, marking a significant step toward AI becoming an interface for real-world financial transactions.
The company said Tuesday that customers can now use the two AI platforms to interact with their Scalable accounts, alongside the broker’s existing app and website. Scalable described the offering as the first of its kind from a European bank and said it has incorporated security measures into the service.
The move marks a shift in the role of generative AI in finance. Until recently, consumers largely used AI tools to research companies, interpret financial statements or obtain general investment information. Scalable is now allowing AI systems to sit closer to the point where information becomes an actual financial decision and transaction.
That could make the development considerably more consequential for the brokerage industry. A customer could ask an AI system to examine their holdings, identify concentrations or compare investment options and then use the same interface to place a trade. The process removes several steps traditionally handled through a bank or brokerage application.
Scalable founder and co-CEO Erik Podzuweit described the rollout as an early stage in a broader transition toward AI-assisted investing.
“A lot of people might still be hesitant to let ChatGPT look at their portfolio, manage their portfolio. So I think that it’s a first step,” Podzuweit told Reuters.
That hesitation is likely to determine how quickly AI trading develops.
There is a fundamental difference between asking an AI model to explain why a stock moved and allowing it to access an investment account. The latter introduces the possibility that an incorrect interpretation, ambiguous instruction, or erroneous recommendation could result in an actual transaction and a financial loss.
Scalable’s strategy appears designed to familiarize customers with that relationship before AI becomes embedded directly into the company’s own platform.
Podzuweit said the company expects broader adoption once AI capabilities are integrated into Scalable’s application. That could eventually make AI less of an optional interface and more of a standard component of the investment experience.
The development is part of a broader race among financial companies to determine how much of the investment process can be automated. The first generation of digital brokers simplified trading by putting financial markets on smartphones and lowering transaction costs.
AI could take the next step by simplifying the decision-making and execution process itself. Instead of searching for an exchange-traded fund, comparing its characteristics and entering an order manually, a customer could potentially describe an investment objective in ordinary language and allow an AI system to translate it into a transaction.
That creates both an opportunity and a new regulatory challenge.
AI could make investing more accessible by giving retail investors inexpensive access to tools capable of processing large quantities of financial information. It could also help customers understand portfolios, identify diversification gaps and compare investments without requiring specialist knowledge.
But access to more information does not guarantee better investment decisions.
Large language models can make errors, misinterpret information or produce persuasive answers that are not appropriate for a particular investor. Financial markets also contain uncertainty that cannot be eliminated by faster analysis.
Podzuweit said he believes AI could eventually produce better investment returns on average, although he acknowledged that this remains to be demonstrated.
The question is therefore not simply whether AI can analyze markets better than humans. It is whether AI can consistently turn that analysis into suitable decisions after accounting for an investor’s objectives, risk tolerance, time horizon and financial circumstances.
That is where AI-powered trading becomes materially different from conventional chatbots.
Once an AI system is connected to a brokerage account, issues such as authentication, transaction limits, customer consent, monitoring and liability become central. A system that can execute trades also needs to distinguish between an instruction to provide information and an instruction to move money or buy an asset.
The technology could also change the economics of brokerage.
Scalable has built its business by offering retail investors a relatively low-cost alternative to traditional banks. AI may reduce the amount of human intervention required for sophisticated services, potentially allowing brokers to offer automated portfolio analysis and other capabilities to large numbers of customers at low marginal cost.
That could put additional pressure on traditional banks and wealth managers.
At the same time, AI could expand the services that digital brokers offer. A customer who previously used a broker to buy stocks and ETFs could eventually receive automated portfolio monitoring, investment research and rebalancing through the same platform.
Scalable has more than 1 million customers and more than €60 billion in assets. It is primarily active in Germany and Austria, while also operating in Italy, Spain, France and the Netherlands. Its decision to work with ChatGPT and Claude is also remarkable because it places general-purpose AI companies closer to the financial infrastructure used by millions of consumers.
The AI platforms are now moving beyond answering questions toward performing actions through external services. Financial accounts are among the most sensitive applications of that capability because an AI agent can potentially move from analyzing information to directly affecting a customer’s assets.
That raises a strategic question for both the AI companies and financial institutions: who ultimately controls the transaction?
If a customer tells an AI assistant to make an investment, the brokerage executes the order, but the recommendation may have originated with the AI model. Establishing responsibility when something goes wrong could become complicated as these systems gain more autonomy.
For now, Scalable is taking a relatively cautious step. It is giving customers an additional way to access their accounts while keeping its existing app and website available.
The longer-term significance is much larger.
The financial industry is gradually moving toward a model in which AI does not merely explain markets but becomes the interface between consumers and financial services. Scalable’s experiment with ChatGPT and Claude provides an early glimpse of that future.
If customers accept the idea of giving AI access to their portfolios, the next phase could involve AI agents continuously monitoring investments, identifying opportunities, executing predefined strategies, and rebalancing portfolios with limited human intervention. That would transform the role of the brokerage app from a place where investors manually conduct transactions into infrastructure operating behind an AI assistant.
