Capital One and Discover Financial Services are currently defending their proposed $35 billion merger in a US court. The companies are seeking to dismiss a consumer lawsuit in Virginia that claims the merger would reduce competition and increase prices. Additionally, Capital One is facing a proposed class action lawsuit alleging that it disclosed personal and financial information of millions of consumers to third parties, including Meta, Google, and Microsoft, without consent. A top regulator has expressed concerns about the merger, suggesting it could lead to higher fees, less choice, and more market concentration. Capital One has labeled the lawsuit as 'speculative.'
