Samsung Electronics joins the $1 trillion market-cap club, becoming the latest AI infrastructure company to reach the exclusive tier alongside Nvidia, TSMC, and Broadcom.

Samsung Electronics crossed $1 trillion in market capitalization, entering a newer wave of trillion-dollar companies tied to AI build-out that includes Nvidia (May 2023), TSMC (2024), and Broadcom (2024)—all making chips, memory, and infrastructure for the AI boom.

The newest $1 trillion members differ from earlier waves: while the first cluster (Apple, Amazon, Microsoft, Alphabet, Meta, Tesla) was built around consumer platforms and software, the AI infrastructure wave rewards suppliers of scarce computing parts, with Samsung adding memory including high-bandwidth memory used in AI systems.

The $1 trillion club has expanded beyond US tech platforms. Non-tech entries include Berkshire Hathaway (first US non-tech company, 2024) and Walmart (first retailer, 2026), while commodity giants Saudi Aramco and PetroChina have also crossed the threshold.
