Capital One Financial Corporation has finalized its acquisition of Discover Financial Services, a deal valued at $35 billion. This acquisition, which took 15 months to complete, is set to impact consumers and small businesses with concerns raised about potential increases in prices and fees. Senator Elizabeth Warren has been vocal in urging the Department of Justice to block the merger, citing anticompetitive risks. Despite consumer bids to impede the deal, the merger has cleared necessary hurdles and is now finalized, marking a significant change in the financial services landscape.
