Big Tech investors worry that artificial intelligence will go rogue

Exposure to AI now represents a short-term risk to investors' according to one London-based portfolio manager

Sam Altman: OpenAI fired and then rapidly rehired its chief executive this month. 

Fund managers who turned to big tech as a low-carbon, high-return bet are growing increasingly anxious over the sector’s experimentation with artificial intelligence.

Exposure to AI now represents a “short-term risk to investors,” said Marcel Stotzel, a London-based portfolio manager at Fidelity International. Mr Stotzel said he’s “worried we’ll get an AI blowback”, which he describes as a situation in which something unexpected triggers a meaningful market decline.
