OpenAI is implementing a 4% checkout fee for AI-driven commerce transactions, signaling the emergence of a monetization layer in 'agentic commerce' where AI systems handle purchasing decisions. This represents a significant consolidation of economic power, as OpenAI positions itself to extract fees from a potentially vast new category of automated transactions, creating a new form of digital taxation on AI-mediated commerce.
