Major insurance broker stocks tumbled Monday as OpenAI approved the first AI insurance application on ChatGPT, triggering a market selloff. Willis Towers Watson (NASDAQ:WTW) led the decline with shares falling 13%, while Arthur J. Gallagher (NYSE:AJG) dropped 9.4%, Brown & Brown (NYSE:BRO) fell 7%, and Marsh & McLennan (NYSE:MRSH) declined 7%. Only AIG saw a modest 2.4% drop.

The market reaction followed OpenAI's announcement that Tuio, a Spanish digital insurer, launched an AI-powered insurance app using WaniWani's distribution infrastructure. The app allows ChatGPT users to receive personalized home insurance quotes through natural conversation, with purchasing capabilities planned for the near future. According to OpenAI, the technology eliminates traditional friction points by removing forms, calls, and intermediaries.

Some investors questioned the market's heavy response, noting the current application focuses on home insurance rather than commercial policies. Industry analysts suggest commercial insurance brokers dealing with complex specialty products may be better insulated from immediate disruption. The development marks a significant shift in insurance distribution, potentially challenging traditional brokerage models as AI platforms gain direct distribution capabilities.
