AI Pioneer Who Shaped Wall Street in 1994 Warns Against Trusting ChatGPT With Your Money
Vasant Dhar helped build one of the first AI-driven hedge funds but urges investors to be cautious about today's AI tools.
Vasant Dhar was deploying artificial intelligence on Wall Street three decades before ChatGPT became a household name, helping construct one of the earliest AI-powered hedge funds back in 1994. Now, as retail and institutional investors alike look to generative AI for financial guidance, Dhar is sounding a clear alarm: the technology is not ready to be trusted with your money.
Dhar's skepticism carries unusual weight given his credentials. Unlike critics who view AI purely from the outside, he has spent his career building and stress-testing machine-learning systems in high-stakes financial environments, giving him a ground-level understanding of where these tools excel and where they dangerously fall short.

Financial decisions carry consequences that a convincing-sounding wrong answer cannot undo. As AI tools become more embedded in personal finance apps and brokerage platforms, scrutinizing the underlying architecture — not just the slick interface — matters more than ever.
