SK hynix remains the No. 1 player in high-bandwidth memory (HBM), while Samsung Electronics is seeking to close the gap with its HBM4 technology, according to primary sources on the two companies' positions. Specific market-share figures cited in public discussion could not be located, and detailed numbers depend on the methodology and timing of individual research firm tallies.
SK hynix's standing as the HBM market leader and Samsung Electronics' pursuit via HBM4 were confirmed across four primary sources describing the current competitive structure. The framing is consistent: SK hynix holds the top position, and Samsung Electronics is mounting a challenge built around its next-generation HBM4 products.
HBM has become a central battleground as AI accelerators require ever-greater memory bandwidth, making the SK hynix–Samsung Electronics rivalry a key storyline in the Korean semiconductor industry.
A dForce press release on free HBM market share produced no search results on the firm's website, leaving no publicly available figures to cite. Any specific market-share numbers in circulation stem from a single research organization's aggregation and may vary depending on the criteria and time period used, so they should be treated with caution.
SK hynix has released quarterly earnings materials, which provide a window into its business performance, though the HBM share dispute itself remains without a settled public number.
Based on the available primary sources, the claim that SK hynix leads the HBM market with Samsung Electronics chasing through HBM4 is True.
Verdict: True
