Is GOOGL Stock a Buy at $4 Trillion? What the Data, Wall Street Analysts Say.

The market does like a good comeback story. After being dismissed and bound for irrelevance after the emergence of OpenAI's ChatGPT, Alphabet's (GOOGL) (GOOG) Google has made a sensational splash in AI over the past year with its Gemini 3 model. And now it is starting 2026 with a bang by surpassing the $4 trillion market cap barrier for the first time. Although market fluctuations occasionally cause it to dip below the $4 trillion mark, Alphabet's market cap has now surpassed Apple's (AAPL) for the first time since 2019.

Ironically, the iPhone maker had a part to play in that when the company revealed that it would use Google's Gemini model to launch a new and improved Siri later this year. This deals another blow to generative AI bellwether OpenAI, whose ChatGPT has suddenly become the laggard in the AI race, with Gemini ahead of the Sam Altman-led company's models across various tasks.
