Samsung Holds 38% DRAM Lead as SK hynix Climbs to 29%: Q3 Share Race and the HBM4 Rematch
📌 Q3 2026 DRAM Share at a Glance
All three cards are Counterpoint Research Q3 2026 Global Memory Tracker figures as reported Nov 5. Shares are revenue-based.
Counterpoint Research's latest Global Memory Tracker puts a clean scoreboard under the DRAM boom: Samsung still leads with 38% revenue share, but SK hynix climbed to 29%—up 4 percentage points from 25% in Q2—and cut the gap from 13pp to 9pp. Micron slipped to 21% (−3pp) and China's CXMT to 9% (from 10%). Behind the share race sits a pricing super-cycle: global DRAM revenue nearly $200 billion in the quarter, up 369% year on year, while bit shipments rose only about 4% and ASP reached $1.9 per Gb. Here is what Counterpoint confirmed, what it implies for HBM4, and how we read Korea's two memory champions.
1. The Scoreboard: Samsung Holds #1, SK hynix Closes In
Reported FactsAccording to Counterpoint's Q3 2026 tracker (published Nov 5), Samsung's DRAM revenue share stayed at 38%—flat versus both Q1 and Q2—keeping the #1 spot. SK hynix moved to 29% from 25% in Q2 (+4pp), narrowing its deficit to Samsung to 9pp from 13pp. Micron's share fell to 21% (−3pp QoQ). CXMT held 9%, down from 10% in Q2. The residual "Others" bucket is about 3% on a 100% revenue-share basis (Counterpoint; Seoul Economic Daily).
Reported FactsSK hynix's DRAM revenue rose by more than 40% quarter on quarter, driven by HBM3E shipments, rising contract prices, and a larger conventional DRAM mix (Counterpoint via Sedaily).
AnalysisFlat Samsung share plus a sharp SK hynix gain is not a Samsung collapse—it is a relative catch-up in a market where almost everyone's revenue is exploding. The investor question is whether SK hynix can keep taking share into HBM4, or whether Samsung's HBM4 reception reverses the HBM hierarchy first.
2. Pricing Super-Cycle: Nearly $200B on Only ~4% More Bits
Reported FactsCounterpoint estimates global DRAM revenue at nearly $200 billion in Q3 2026, up 369% YoY. Bit shipments rose only about 4% over the same period, and average selling price reached $1.9 per Gb—so most of the revenue jump is price, not volume (Counterpoint, Nov 5).
Reported FactsConventional DRAM grew even faster than HBM in revenue terms: DDR revenue rose about 500% YoY and LPDDR nearly 400% YoY. HBM revenue almost doubled, yet HBM's share of total DRAM revenue declined because DDR and LPDDR expanded faster (Counterpoint).
Reported FactsOn the demand side, Counterpoint notes the GPU-to-CPU DRAM ratio is narrowing from roughly 4:1 toward 2:1, and NVIDIA's Vera Rubin rack is described as needing about 1.5 TB of CPU DRAM per socket—nearly 3× the prior generation—supporting server-DRAM intensity beyond HBM alone (Counterpoint).
AnalysisA 369% revenue surge on ~4% bits is the textbook pricing super-cycle. LTAs and the absence of major new fabs until 2028 (per Counterpoint) help explain why contract prices can stay elevated even as HBM's share of the mix slips relatively.
3. Share and Mix Matrix
| Item | Q3 2026 figure | Why it matters | Source |
|---|---|---|---|
| Samsung DRAM revenue share | 38% (#1, flat vs Q1/Q2) | Still leads overall DRAM dollars | Counterpoint / Sedaily, Nov 5 |
| SK hynix DRAM revenue share | 29% (+4pp from 25% in Q2) | Gap vs Samsung cut to 9pp from 13pp | Counterpoint / Sedaily, Nov 5 |
| Micron / CXMT share | 21% (−3pp) / 9% (from 10%) | Share lost mostly to SK hynix's jump | Counterpoint / Sedaily, Nov 5 |
| Global DRAM revenue | Nearly $200B; +369% YoY | Pricing-led boom, not a bit flood | Counterpoint, Nov 5 |
| Bit shipments / ASP | ~+4% YoY / $1.9 per Gb | Confirms price > volume story | Counterpoint, Nov 5 |
| HBM share (Q2 reference) | SK hynix 50%; Samsung 33% | Baseline before HBM4 rematch | Counterpoint, Nov 5 |
| DDR / LPDDR revenue | ~+500% / ~+400% YoY | Conventional DRAM outpaced HBM mix share | Counterpoint, Nov 5 |
| Supply backdrop | LTAs support prices; major new fabs not until 2028 | Tight capacity into late decade | Counterpoint, Nov 5 |

4. HBM4 Rematch: Can Samsung Reclaim #1?
Reported FactsCounterpoint's Q2 HBM reference shares were SK hynix 50% and Samsung 33%. The firm expects Samsung to reclaim HBM leadership next year as its HBM4 is well received, while SK hynix's HBM3E growth has slowed (Counterpoint; Sedaily, Nov 5).
Company ContextOn Oct 28, SK hynix's Q3 results commentary reiterated long-term agreements and tight HBM supply as structural supports for the cycle—consistent with Counterpoint's view that LTAs help hold prices while major new fabs are not expected until 2028 (SK hynix Newsroom; Counterpoint).
AnalysisOverall DRAM share and HBM share can diverge. SK hynix's +4pp overall DRAM gain in Q3 leaned on HBM3E and more conventional DRAM at rising prices. If Samsung's HBM4 ramps as Counterpoint expects, HBM leadership could flip even while SK hynix remains strong in total DRAM dollars.
AnalysisFor foreign investors watching Korea Tech Alpha names, the near-term tape still prices the pricing super-cycle; the medium-term debate is HBM4 qualification wins versus how long DDR/LPDDR ASP stays elevated with limited new fab supply until 2028.
💡 Market Analyst Takeaway
AnalysisBase case: Samsung keeps overall DRAM #1 near the high-30s share band while SK hynix holds the high-20s after its Q3 catch-up; HBM leadership is the swing factor into 2027 as Counterpoint flags an HBM4-led Samsung reclaim. Pricing remains the bigger P&L driver than bit growth while ASP sits near $1.9/Gb and LTAs plus 2028-dated fab timing limit supply response.
AnalysisWatch: (1) HBM4 customer qualifications and any Counterpoint/TrendForce updates that flip Q2's 50%/33% HBM split; (2) whether DDR/LPDDR ASP cools before new fabs; (3) Micron's ability to stop the −3pp share bleed; (4) CXMT's single-digit share path as China capacity adds bits later in the decade.
5. What to Watch Next
- HBM4 design-win commentary from Samsung and customers that would validate Counterpoint's reclaim thesis.
- Next-quarter DRAM ASP and bit guides — whether the ~$1.9/Gb print and ~4% bit growth pattern persists.
- LTA renewals and fab timelines through 2027–2028 disclosures from SK hynix and Samsung IR.
