Google Shares Plummet $500 Billion as AI Search Summaries Impact Ad Revenue

Alphabet, Google's parent company, saw its market value shrink by an astonishing $500 billion following an announcement that its new AI-driven search features are directly impacting its advertising revenue. The firm's shares consequently plummeted to a six-month low.

The company detailed that the generative AI summaries, designed to provide quick answers at the top of search results, are leading users to spend less time clicking on traditional adverts. This shift represents a tangible threat to Google's established business model, which has historically relied heavily on ad placements linked to search queries.

Analysts are now scrutinising how Google plans to mitigate this self-inflicted damage while continuing to integrate AI into its services. The current trajectory suggests a complex balancing act between technological advancement and maintaining the lucrative advertising ecosystem that underpins its financial dominance.
