Alphabet, the parent company of Google, witnessed its shares climb 4% on Thursday, marking a second consecutive day of gains. The surge comes as investors enthusiastically responded to a flurry of artificial intelligence (AI) updates unveiled by the tech giant, notably the widespread rollout of "AI Mode" to all its U.S. users.

The positive market reaction also stemmed from the disclosure of a $249.99-a-month subscription tier for AI power users, an offering teased at Alphabet's recent annual developer conference. This premium service appears to have allayed concerns regarding the substantial financial outlays associated with the company's aggressive AI development initiatives.

Confidence in Search Growth and Monetization

Citi analyst Ronald Josey expressed increased confidence in Alphabet's trajectory following the conference. "After the conference, we are incrementally confident that Google can deliver continued search growth while ramping monetization suggesting improving execution," Josey wrote in a research note. This sentiment reflects a crucial point of focus for investors: how Google plans to integrate and monetize AI without cannibalizing its core search advertising business.

CEO Sundar Pichai directly addressed these concerns, asserting that the rise of generative AI would not come at the full expense of online search. His comments aimed to assuage fears of a behavioral shift where users might increasingly turn to AI chatbots instead of traditional search engines.

"AI Mode" and the Future of Advertising

A significant announcement from the conference was the widespread availability of "AI Mode" for Google Search across the United States. This new feature allows users to switch their search experience into an AI-powered interface, promising more advanced and personalized results.

Further bolstering investor confidence was the insight from a Google search team executive, who indicated that leveraging AI to answer more complex queries could unlock novel avenues for displaying more relevant and useful advertisements. Given that advertising constitutes the majority of Google's revenue, this potential for AI-driven ad innovation is a key driver for future growth.

"We believe monetization of AI Mode is likely to 'soon' follow the U.S. launch," noted Citi's Josey, underscoring the market's expectation for swift revenue generation from these new AI features.

Alphabet's Class C shares closed up 4% at $175.27, reaching levels not seen in three months. Despite this recent uplift, the stock remains down approximately 7% year-to-date, highlighting the significant impact of earlier market anxieties surrounding AI's disruptive potential on Google's core business model. The current rally suggests a renewed optimism in Alphabet's strategic direction and its ability to seamlessly integrate AI into its profitable ecosystem.
