Summary
Andreessen Horowitz's fund has described Samsung Electronics and SK Hynix as "globally critical companies, as important as Nvidia, because memory has become pivotal in AI." The comment positions the two South Korean memory makers as central to the AI hardware supply chain rather than as cyclical component suppliers.
Coverage across several outlets points to SK Hynix as the most Nvidia-exposed of the memory producers. Reports describe it as the leading supplier of high-bandwidth memory (HBM) used in Nvidia's AI accelerators, and one analysis cites SK Hynix holding roughly 58% of that segment, with Samsung and Micron at about 21% each. Reporting also notes SK Hynix has joined Micron and Samsung Electronics in crossing a $1 trillion market capitalization.
Share prices have tracked Nvidia's results and AI financing sentiment closely. Samsung and SK Hynix shares reportedly rallied to record highs after Nvidia posted strong quarterly earnings and signaled continued AI-driven demand. In a separate episode, Samsung fell 8% as concerns over AI infrastructure financing weighed on global semiconductor stocks, while SK Hynix also slid amid worries about Nvidia-linked financing. Other reports point to competitive pressure, noting Nvidia's China AI chip share is under pressure from Huawei.
On the investment side, Samsung and SK Hynix are accelerating semiconductor capacity spending, according to a 1H26 facility investment report, as AI demand pushes capacity expansion and advanced-process upgrades. The sources reviewed for this summary are headlines and brief excerpts, so specific deal values, investment amounts, and exact dates for individual market moves could not be verified.
