Google shares lose more than $100 billion after AI chatbot Bard flubs answer in ad

Shares of Google’s parent company lost more than $100 billion in market value on Wednesday after its Bard chatbot ad showed inaccurate information and analysts said its AI search event lacked details on how it will answer Microsoft’s ChatGPT challenge.

Reuters was first to point out the error in Google’s advertisement, which debuted Monday, about which satellite first took pictures of a planet outside the Earth’s solar system. Shares of the company’s parent Alphabet fell 8% or $8.59 a share to $99.05 and was one of the most actively traded on U.S. exchanges.

The tech giant posted a short GIF video of Bard in action via Twitter, describing the chatbot as a “launchpad for curiosity” that would help simplify complex topics, but it delivered an inaccurate answer that was spotted just hours before the launch event for Bard in Paris.
