Mitsubishi UFJ Bank Rolls Out ChatGPT Enterprise to 35,000 Employees, Targeting 20-30% Workload Cuts
1 articles · Updated · OpenAI · May 28
Mitsubishi UFJ Bank has begun a phased 2026 rollout of ChatGPT Enterprise to about 35,000 employees, making the tool available for daily work as MUFG pushes to become an AI-native financial group.
100% of employees receiving accounts completed mandatory e-learning before access, part of governance and security controls OpenAI helped design for a bank-wide deployment.
1,800 custom GPTs were created in four months after OpenAI-led training, with department-level "AI bankers" emerging to handle specialized workflows and spread internal know-how.
20-30% workload reductions have already been reported in selected research tasks, with MUFG saying the time saved will be redirected to customer visits, proposals and human decision-making.
MUFG is extending the partnership beyond internal operations into customer products, including Moneytree, WealthNavi and a planned AI concierge and advisory platform for its emutt digital bank.
As its bankers build 1,800 AI bots, how will MUFG defend against the very AI threats it now fears?
When MUFG's AI concierge gives flawed financial advice, who is held responsible for the customer's losses?
