Alphabet Joins $3 Trillion Club Amid AI Boom and Legal Victory

Alphabet Inc. has cemented its position among tech titans by reaching a $3 trillion market valuation, becoming the fourth company in history to achieve this milestone. The Google parent company's shares closed at $251.76 on September 15, 2025, marking a 4.3% gain, with pre-market trading pushing the price to $254.11.

The surge comes as Alphabet's AI initiatives bear fruit, with its Gemini AI model and custom chip development driving a 32% revenue increase in its cloud division. A favorable U.S. court ruling preserving Chrome and Android operations further bolstered investor confidence.

With a forward P/E ratio of 23—the lowest among the "Magnificent 7" tech stocks—Alphabet's valuation appears relatively attractive. Analysts project $2.33 EPS for the current quarter, representing 9.9% year-over-year growth.
