Alphabet Inc lost $100 billion in market value on Wednesday after its new chatbot shared inaccurate information in a promotional video and a company event failed to dazzle, feeding worries that the Google parent is losing ground to rival Microsoft Corp (MSFT.O).
Alphabet shares slid as much as 9% during regular trading with volumes nearly three times the 50-day moving average. They pared losses after hours and were roughly flat. The stock had lost 40% of its value last year but rallied 15% since the beginning of this year, excluding Wednesday's losses.
Reuters was first to point out an error in Google's advertisement for chatbot Bard, which debuted on Monday, about which satellite first took pictures of a planet outside the Earth's solar system.
Google has been on its heels after OpenAI, a startup Microsoft is backing with around $10 billion, introduced software in November that has wowed consumers and become a fixation in Silicon Valley circles for its surprisingly accurate and well-written answers to simple prompts.
Google's live-streamed presentation on Wednesday morning did not include details about how and when it would integrate Bard into its core search function. A day earlier, Microsoft held an event touting that it had already released to the public a version of its Bing search with ChatGPT functions integrated.
Bard's error was discovered just before the presentation by Google, based in Mountain View, California.
