Can Alphabet's AI Innovation Help Google Search Regain Market Share?

Alphabet's Google Search market share dipped to 89.54% in May 2025, prompting AI innovations like AI Overviews and Circle to Search, which are boosting user engagement and are expected to drive an 11% CAGR in Google Search revenues from 2024-2027; however, GOOGL faces increasing competition from Microsoft's Bing and Baidu, both of which are integrating advanced AI capabilities into their search engines. Despite these efforts, GOOGL shares have underperformed year-to-date, dropping 11.2%, and trade at a premium with a forward 12-month Price/Sales of 6.03X.

Analysis

Alphabet's Google Search, despite its long-standing market dominance, experienced a decline in global market share to 89.54% in May 2025, and 89.62% as of March 2025, its lowest in two decades, primarily due to the rise of Generative AI applications like Perplexity and OpenAI's ChatGPT, alongside intensified competition from Microsoft's Bing (4% market share) and Baidu's (0.69% market share) AI-enhanced offerings. To counter this, Alphabet is aggressively integrating AI into its search products; AI Overviews, now used by over 1.5 billion people monthly, has driven a more than 10% increase in Google usage for supportive queries in key markets, while Circle to Search was available on 250 million devices by Q1 2025 with usage up approximately 40% during the quarter. These initiatives are projected to contribute to an 11% compound annual growth rate (CAGR) for Google Search & other revenues between 2024 and 2027. However, Microsoft is bolstering Bing with OpenAI's technology, introducing Copilot Search and Bing Video Creator powered by Sora, and Baidu is advancing its search with self-developed ERNIE models. Alphabet's shares have underperformed, dropping 11.2% year-to-date, lagging both the Zacks Computer & Technology sector and the Zacks Internet Services industry. The stock trades at a premium with a forward 12-month Price/Sales ratio of 6.03X compared to the industry's 5.05X, and holds a Zacks Value Score of C. Despite these challenges, consensus estimates for Q2 2025 earnings per share stand at $2.12, indicating 12.17% year-over-year growth, and full-year 2025 earnings are projected at $9.47 per share, suggesting 17.79% year-over-year growth.

Key Decisions for Investors

• Evaluate the sustainability of Google's search market share (currently 89.54%) in light of escalating AI-driven competition from Microsoft and Baidu, and closely track the user adoption and engagement metrics of Google's AI innovations like AI Overviews and Circle to Search.
• Consider the projected 11% CAGR in Google Search revenues through 2027 and anticipated earnings growth (12.17% YoY for Q2 2025) against the backdrop of the stock's recent 11.2% YTD underperformance and its premium forward P/S valuation of 6.03X.
• Note the current Zacks Rank #3 (Hold) for GOOGL, suggesting a neutral short-term outlook, and monitor for shifts in competitive dynamics or AI product traction that could alter this stance.
