As AI Propels Alphabet Stock Upward, GOOGL Nears $4 Trillion Valuation

Alphabet (GOOGL) stock climbed to a new high on Nov. 19 before closing the day about 3% higher. The jump came after Google unveiled its newest artificial intelligence (AI) model, Gemini 3, which the company says raises the bar for AI performance by delivering more concise, improved responses. The launch has renewed optimism among investors as AI has been a key driver of Alphabet’s growth.

Notably, Alphabet is showing strong momentum across all of its core businesses, and AI is playing a key role in that progress. With a market capitalization of roughly $3.54 trillion at the time of writing, Alphabet now appears well on its way to a $4 trillion valuation as AI becomes the engine powering its next phase of expansion.
