World's 15 Most Valuable Tech Companies
By Goldsea Staff | 20 Oct, 2025

Among them are companies that get little US media coverage but are critical to the world's hi-tech supply chain.

Few people know that progress in state-of-the-art chip production depends on ASML, a Dutch firm that makes lithography equipment to enable cutting-edge 3 nanometer processes, and that the first company to fabricate chips using that process is Taiwan's TSMC, with Korea's Samsung following behind.  Without those two little-mentioned firms, semiconductor giants like Nvidia and Broadcom would still be making chips that can do only a tenth of the processing per watt of processing power.

Another giant little-known in the West is TenCent, the Chinese firm whose WeChat mobile app combines the functionality of Google, Meta and Paypal for the 1 billion Chinese with a mobile phone but also 100 - 200 millions users outside of China.
