According to Lex Sokolin (@LexSokolin), the hypothetical full-scale deployment of Visa, Mastercard, OpenAI, and Anthropic on Ethereum could introduce over 4 billion users and $14 trillion in payment volume to the blockchain, transforming global identity systems and enabling AI-powered financial services (source: Twitter, May 7, 2025). For cryptocurrency traders, such integration would dramatically boost Ethereum's transaction volumes, liquidity, and utility, potentially increasing ETH demand and driving correlated altcoin growth, particularly in Layer 2 scaling and decentralized identity sectors.
