TIAA's AI system caught a 76-year-old customer's $3 million（約4.8億円） retirement withdrawal scam, but a human fraud team was needed to stop it—underscoring why technology and people must work together to protect assets.

What happened: TIAA's AI flagged an unusual request from a 76-year-old retiree attempting to withdraw his entire $3 million（約4.8億円） retirement portfolio. A portfolio manager escalated the out-of-pattern withdrawal to the fraud team, who spent hours convincing the customer he was being deceived. A fraud specialist eventually contacted the man's daughter, and TIAA stopped the money from moving.

Why it matters: Scam losses are surging—over $20.8 billion（約3.3兆円） was lost to about 1 million cybercrime complaints in 2025 alone, with older adults accounting for the largest number of complaints and total losses. TIAA's CEO emphasized that AI alone would not have protected this customer; human judgment and intervention were essential to prevent the fraud.

What to watch: TIAA's CEO argues that jobs tied to cybersecurity, fraud prevention, and AI oversight will grow as AI becomes more embedded in business. She sees agility as the most important skill set, and emphasizes that organizations need to have open conversations with workers about how AI will reshape their roles.
