Green Dot is a financial technology company and registered bank holding company that provides banking and payment products to consumers and businesses through its wholly owned subsidiary, Green Dot Bank. Green Dot's consumer business offers prepaid debit cards, checking accounts, secured credit cards, and gift cards, primarily targeting lower- and moderate-income Americans. Its flagship consumer product, GO2bank, is a mobile banking app with overdraft protection, high-yield savings, and credit-building tools. Consumer products are distributed through a retail network of over 90,000 locations, with Walmart as its largest retail partner through 2033. Green Dot's B2B embedded finance business, branded "Arc by Green Dot," provides banking-as-a-service (BaaS) to companies that want to embed financial products into their own platforms, with large partners including Apple, Intuit, and Amazon. Green Dot also processes roughly 13M tax refunds annually through its Santa Barbara Tax Products Group subsidiary and operates the Green Dot Network, a cash transfer network enabling deposits and withdrawals at retail locations. Green Dot earns revenue through interchange fees, account fees, BaaS program management fees, net interest income on deposits, and tax and money processing fees. The consumer segment is in secular decline as prepaid card usage moderates, while B2B is the primary growth engine — Green Dot is actively signing new BaaS partners and optimizing its bank balance sheet to grow deposit-based interest income. In November 2025, Green Dot announced a merger with CommerceOne Financial and a simultaneous sale of its non-bank fintech and payments operations to Smith Ventures for $690M.
