Why Alphabet shares crashed: How Google AI Mode is eating into search ad revenue

Alphabet's shares dropped over $500 billion after reporting lower-than-expected revenue of $127.6 billion, missing analyst targets by $1.4 billion. Search ad revenue growth slowed to 12% from 17% due to AI Mode, which earns less per query. Cloud revenue nearly doubled to $30.7 billion. Google plans to add more ads to AI Mode globally to offset the revenue decline.
