AI Pioneer Who Shook Wall Street in 1994 Warns on ChatGPT Investing
Vasant Dhar helped build one of the first AI hedge funds. Now he's cautioning everyday investors about trusting ChatGPT with their money.
Vasant Dhar was doing AI on Wall Street before most traders had heard the term. Back in 1994, he helped pioneer one of the first AI-driven hedge funds — so when he says he wouldn't trust ChatGPT with his own money, you should probably listen up.
Dhar's skepticism isn't technophobia. It's pattern recognition. He's watched AI evolve across three decades of live markets, where being wrong costs real dollars.

The core problem is that large language models like ChatGPT are built to produce fluent, confident-sounding text. Markets punish confidence without edge. A system optimized to sound right is not the same as a system optimized to be right when money is on the line. That distinction matters more than any hype cycle.

Dhar's career arc is worth respecting here. He didn't come out against AI — he came out against misapplied AI. If one of the original architects of machine-learning-based investing is drawing that line, retail traders should think hard before letting a general-purpose chatbot drive their next trade.
