Alphabet's Stock Gains 0.55% on $5.26 Billion Volume as 13th Most Traded Amid AI Advertising Push New Podcast Dives into AI-Driven Ads Transparency

Alphabet's shares rose 0.55% on August 29, 2025, with a trading volume of $5.26 billion, ranking 13th in market activity. The company launched a new podcast series, "Google Ads Decoded," to explain AI-driven advertising tools like AI Max for Search campaigns and Performance Max channel reporting. These updates aim to enhance transparency and address advertiser concerns about automation complexities.

The podcast features product managers discussing AI Max's technical implementation, including search term matching, text customization, and URL expansion to optimize ad reach while maintaining advertiser control. Performance Max channel reporting, rolled out since May 30, provides visibility into campaign performance across Google's platforms, such as Search, YouTube, and Gmail, without equalizing channel-specific metrics.

Alphabet's Q1 2025 earnings exceeded expectations, with revenue of $90.23 billion and $2.81 earnings per share. CEO Sundar Pichai highlighted the "unique full stack approach to AI" and a $75 billion annual investment in AI infrastructure. The company faces antitrust scrutiny, including a ruling that Google holds monopolistic power in online ad markets, though it continues to expand AI capabilities like Gemini 2.5 to drive growth.

Industry testing of AI Max revealed mixed results, with 99% of search terms generating zero conversions. Advertisers report challenges with keywordless matching and underperformance on the Search Partner Network. Despite these issues, Google emphasizes enhanced reporting tools to help marketers adapt to automated systems, balancing broad reach with conversion efficiency.
