What would be the outcome of the potential merger between Capital One and Discover?

The merger would establish Capital One as the largest credit card issuer in the United States, surpassing JPMorgan Chase. This significant consolidation in the credit card industry was announced about a year ago, but still requires full federal regulatory approval before it can be finalized. Currently, shareholders of both companies are voting on this potential merger, which represents a major shift in the competitive landscape of credit card companies. If approved, the deal would reshape the hierarchy of credit card issuers in the American financial market.
