Alphabet's capitalization exceeds $4 trillion for the first time Apple has chosen Google's AI for Siri
Alphabet shares hit an all-time record in trading

The market capitalization of Alphabet - Google's holding company - exceeded $4 trillion for the first time during trading on January 12. The shares were boosted by CNBC's report that Apple has chosen Google's Gemini artificial intelligence as the basis for its AI, which will power its updated Siri voice assistant.
Details
The value of Alphabet Class A shares jumped 1.7% to $334.04 during trading on Monday. This was a new record for the company's stock. This allowed Alphabet to become the fourth technology company with a market capitalization above $4 trillion. Earlier this threshold was reached by Nvidia, Microsoft and Apple.
Alphabet's achievement is due to investors' optimism about Google's artificial intelligence models and their ability to compete with those of OpenAI, which created ChatGPT, the Financial Times writes. In particular, Apple chose Google as a partner for the development of artificial intelligence, the company said in a statement quoted by CNBC.
What the partnership with Apple entails
Apple has entered into a multi-year partnership with Google to incorporate artificial intelligence into its products, including voice assistant Siri, CNBC reported. The first features based on the new AI will appear in iPhones as early as this year. The agreement includes the use of Gemini models and Google's cloud-based solutions in future Apple Foundation Models - Apple's own base models of artificial intelligence being developed for integration into its devices and services.
"After careful evaluation, we have concluded that Google's technology is the best foundation for Apple Foundation Models, and we look forward to the innovative opportunities this will bring to our users," CNBC quoted Apple as saying.
That Apple is in talks with Google to use a custom Gemini for a new version of Siri was reported by Bloomberg in August. And for the first time that Google expects to integrate its Gemini artificial intelligence into the iPhone as one of the built-in chatbots, Alphabet CEO Sundar Pichai said in April 2025.
Last week, Alphabet overtook Apple in terms of capitalization for the first time since 2019. Apple shares were up 0.7% at the moment in trading on January 12. The company's market value is now about $3.8 trillion.
Context
Apple has so far been largely left out of the AI boom that has swept Wall Street following the launch of OpenAI's ChatGPT in late 2022. This has increased pressure on the iPhone maker: the market has been waiting for new relevant solutions from Apple. Last year, Apple delayed a major Siri update until 2026, despite already launching ad campaigns for the new assistant.
