Google acknowledged that its AI-generated search summaries are affecting ad revenue, and its stock fell as about $500bn in value was lost. Google reported negative cash flow of -$9.06 billion in its Q3 earnings.

AI brief

Google's stock fell as much as ten percent after quarterly earnings showed search revenue growing just 12 percent, slower than expected, while cloud revenue more than doubled to $30.7 billion. Google acknowledged that its fast-growing AI mode brings in less revenue.

Why it matters: It suggests Google's shift toward AI search may weigh on its core advertising revenue.
