Japan’s MUFG, one of the world’s largest financial groups, is going all-in on AI. They’ve rolled out ChatGPT Enterprise to 35,000 employees at Mitsubishi UFJ Bank, marking a major shift in how a traditional bank operates. But this isn’t just about automating tasks; MUFG sees AI as a way to extend human thinking and creativity. They’re building a culture where AI is a natural part of everyday work, combining top-down leadership support with bottom-up employee empowerment. The bank is working closely with OpenAI on security and governance, key concerns for any financial institution. This massive deployment, starting in 2026, is part of a larger vision to become an ‘AI-native’ company, fundamentally changing the nature of finance. Why it matters: This move shows that even the most traditional, heavily regulated industries are betting big on generative AI, moving beyond simple automation to fundamentally rethink their business models and customer experiences.
