Alphabet’s stock rally has pushed its market value past $4 trillion, making it the fourth company in history to reach that milestone.
The Google parent joined Nvidia, Microsoft, and Apple in the elite club as shares climbed on the back of the ongoing AI boom. The stock jumped as much as 2% on Monday before easing, extending a surge that has already seen Alphabet gain about 65% over the past year.
The milestone also marks the first time in nearly seven years that Alphabet has overtaken Apple in market capitalization. Apple’s valuation currently sits just under $3.8 trillion.
Investor confidence has been fueled by several recent moves, including Apple’s decision to use Google’s Gemini models to power upcoming AI features across its devices. Under the partnership, Gemini and Google’s cloud technology will help drive Apple’s next generation of AI tools, including a more personalized version of Siri.
Alphabet has also strengthened its position in the AI race with the launch of its latest Gemini 3 model, which has received strong early reviews and is seen as a serious competitor to offerings from OpenAI and other rivals.
Beyond software, investors are betting on Google’s growing advantage in AI infrastructure, from its in-house TPU chips to its massive distribution network through Search, YouTube, and other platforms — giving Alphabet a rare end-to-end edge in the fast-moving AI market.
