ChatGPT Finances: Security Risks of Centralized Net Worth

OpenAI is letting ChatGPT Pro subscribers link bank accounts, investment portfolios, and credit cards directly to the chatbot. This new "Finances" experience is available in preview for Pro subscribers paying $200 per month. What's interesting is how it works. ChatGPT connects accounts through Plaid, which powers many popular financial apps and institutions. Once linked, ChatGPT creates a live dashboard of spending, subscriptions, payments, and investment performance. It can also answer financial questions using your real account data, like helping you plan to buy a house. OpenAI states the system can read balances and transactions but cannot see full account numbers, move money, or change account settings. The feature runs on GPT-5.5, which OpenAI claims is better at handling complex personal finance questions. Users can disconnect accounts anytime, and synced data is removed from OpenAI's systems within 30 days. However, past conversations referencing that data are not automatically deleted. Security experts are raising concerns about the aggregation risk. They warn that a single account takeover could give someone a consolidated picture of your balances, spending, investments, debts, and financial history. This means centralizing financial data inside one platform creates a "high-value target" for cybercriminals. This matters because it highlights the potential risks of sharing all your financial information with a single AI platform.
