Google’s parent company, Alphabet, surpassed Microsoft today to become the world’s third-largest company by market capitalization, marking a significant shift among leading technology firms.

The milestone comes as Google’s stock has been climbing since last Friday, when Warren Buffett’s Berkshire Hathaway disclosed a $4.9 billion stake in Alphabet. The rare tech investment marks Buffett’s first major bet on the search giant and one of the largest additions to his portfolio this year.

Alphabet’s strong search engine and advertising business continue to generate robust cash flow, giving the company scope to fund its AI ambitions.

The market cap reshuffle underscores intensifying competition among major tech firms, all battling for dominance in AI, cloud, and data‑centre infrastructure. Buffett’s endorsement offers a notable validation of Alphabet’s strategy as the tech landscape evolves.
