Alphabet Inc., the parent company of Google, has crossed a market capitalisation of $3 trillion, becoming only the fourth publicly listed firm to reach this milestone after Apple, Microsoft and Nvidia. The company’s stock climbed 4.3 per cent to close at $251.22 on 15 September 2025, lifting its market cap to $3.05 trillion.
Google was listed on 19 August 2004 at a valuation of $23 billion (IPO price $85). It restructured into Alphabet Inc. in October 2015, setting the stage for faster growth and diversification.
Alphabet hit $1 trillion in January 2020 and $2 trillion in November 2021, before tripling its market value to reach $3 trillion in September 2025.
