Alphabet Inc, the parent of Google, has entered the $4 trillion market capitalisation group following a rise in investor optimism around its AI advancements.
The surge in share prices came shortly after Alphabet secured a multi-year deal with Apple to integrate Google’s Gemini models into Apple’s voice assistant, Siri.
On January 13, 2026, Alphabet’s shares climbed up to 1.7% to reach $334.04, pushing the company’s valuation past the $4 trillion mark. This development elevated Alphabet to the position of Wall Street’s second-most valuable firm, overtaking Apple for the first time since 2019.
The increase came in the wake of an agreement with Apple that will employ Google’s Gemini AI models and cloud infrastructure for Siri and other AI-led features.
Alphabet has experienced significant valuation growth over the past 15 years. In December 2010, the company's market cap stood at $190 billion. By 2014, it reached $360 billion driven by mobile advertising and Android growth.
In January 2020, it joined the $1 trillion club. Alphabet crossed the $2 trillion valuation in April 2024 and exceeded $3 trillion in September 2025. The latest rise to $4 trillion has been propelled by new AI product deployment and major enterprise partnerships.
Gemini 3, launched in November 2025, performed strongly on AI benchmarks. This performance, along with contract announcements, supported Alphabet’s expanding image in the AI segment.
Google Cloud's revenue had a 34% rise in Q3 2025, with $1,55,000 crore in unrecognised sales contracts, highlighting business momentum.

The collaboration with Apple is accompanied by a deal with Samsung to expand Gemini integration across 800 million mobile devices in 2026, up from 400 million a year ago.
Additionally, reports suggest Meta Platforms has shown interest in Google’s TPU chips for potential use starting 2027. Alphabet also gained relief in September 2025 when a federal judge ruled that it would not need to divest Chrome, offering some respite in legal matters.
Alphabet’s entry into the $4 trillion market capitalisation tier is backed by increased AI adoption, strong cloud growth, and influential deals with Apple and Samsung. The rapid rise in valuation demonstrates market confidence supported by ongoing product integration and operational performance.
