Global DRAM revenue jumped 369% year over year during the third quarter of 2026 as artificial intelligence and data center demand triggered widespread price surges across the semiconductor supply chain. Samsung Electronics led the sector with a 38% market share, followed by SK Hynix at 29% and Micron at 21%. While server memory contract prices pushed industry earnings to historic highs, actual bit shipment volume grew just 4% over the previous quarter.
Counterpoint Research released its memory tracking report showing Samsung widened its industry lead with a 5 percentage point gain compared to the same period last year. SK Hynix fell 4 percentage points to capture 29% of global sales. Micron dropped 5 percentage points to settle at 21%. China based memory maker CXMT took a 9% share, up 4 percentage points from the prior year but down 1 percentage point from the second quarter. The research firm expects CXMT to face mounting margin pressure as competitors begin mass shipments of high priced HBM4 silicon.
Price inflation propelled industry earnings rather than factory production gains. Counterpoint Research senior analyst Jeongku Choi stated that bit shipments edged up roughly 4% quarter over quarter, yet total revenue climbed to 4.7 times the level recorded 1 year earlier. Average selling prices hit 1.9 dollars per Gb. Buyers now accept higher supplier quotes to secure allocation rather than negotiating for discounts, positioning memory makers for another record revenue period in the fourth quarter.
SK Hynix previously held the top spot in HBM3E memory, but its expansion pace has cooled. Counterpoint Research research director MS Hwang reported that customer reception for Samsung HBM4 remains positive, creating an opening for Samsung to claim the top high bandwidth memory position by 2027. Tight production capacity will likely keep market prices high through 2027 because new manufacturing facilities will not begin operations until 2028. Long term volume agreements between vendors and cloud providers will determine near term supplier earnings.
High bandwidth memory revenue almost doubled, yet high bandwidth products lost total market share because standard server memory expanded at a faster speed. Counterpoint Research associate director Brady Wang explained that agentic AI workloads pushed DDR revenue up 500% and low power DRAM sales up nearly 400% year over year. Data center racks built around the Nvidia Vera Rubin platform pack up to 1.5TB of DRAM per CPU socket, almost doubling previous hardware standards. Cloud architectures have adjusted accelerator ratios from 4 to 1 down to 2 to 1, with enterprise deployments heading toward a 1 to 1 balance between processors and graphics silicon.
