Alphabet Inc., the parent company of Google, has crossed a $4 trillion market capitalization as of January 12, reaching the highest level in the technology sector, according to international media reports.

The milestone was achieved after the company’s stock rose 6% so far this year, reflecting renewed investor confidence. Alphabet now becomes the fourth company in the world to surpass a $4 trillion market cap, following Nvidia, Microsoft, and Apple.

Analysts attribute the surge to Alphabet’s strategic focus on artificial intelligence (AI), which has alleviated previous investor concerns about its business model and future prospects. This confidence has driven the company’s shares upward significantly.

On Wednesday, Alphabet overtook Apple for the first time since 2019, becoming the second most valuable company globally by market capitalization.

Alphabet shares have risen 65% in 2025, outperforming other companies in the “Magnificent Seven” tech group on Wall Street, demonstrating strong performance relative to peers.

Analysts highlight that these levels reflect a major shift in investor sentiment and confidence in Alphabet’s long-term strategy.
