Visa

Visa is one of the world's largest payment network companies, operating the electronic infrastructure that routes credit and debit card transactions between consumers, merchants, and financial institutions globally. Rather than issuing cards or extending credit directly, Visa functions as a network intermediary, earning fees on the volume of payments that flow across its rails.

In the technology space, Visa is significant both as critical financial infrastructure and as an active partner in emerging payment technologies. The company has worked to modernize payment systems through capabilities such as tokenization, real-time payments, and open banking integrations, keeping it relevant as digital commerce evolves.

Most recently, Visa has positioned itself at the intersection of artificial intelligence and commerce. The company has announced initiatives — including a partnership with OpenAI — to enable AI agents, autonomous software systems that act on a user's behalf, to make purchases and complete financial transactions independently without requiring human approval for each transaction. This push toward so-called "agentic commerce" signals Visa's intent to remain central to how money moves as AI-driven automation reshapes consumer and business spending.
