Samsung Electronics' sixth-generation High Bandwidth Memory (HBM), HBM4, has surpassed $1 billion in sales in just four months after entering mass production, marking a major milestone in the rapidly growing artificial intelligence (AI) memory market.
According to industry sources on Monday, Samsung's HBM4 sales exceeded the $1 billion mark following a sharp increase in demand for next-generation AI memory products. The figure is expected to surpass $1.2 billion by the end of June, less than five months after the company began mass production.
Samsung became the world's first semiconductor company to mass-produce and ship HBM4 on Feb. 12, 2026, gaining an early lead in the next-generation AI memory race.
Industry observers now expect HBM4 revenue to exceed $10 billion by the end of this year, an unprecedented achievement for a newly launched memory product in its first year of commercialization.
The rapid growth of HBM4 has been driven by surging investment in AI infrastructure worldwide.
As generative AI models become larger and more sophisticated, demand for high-performance memory capable of processing massive amounts of data has risen sharply. Market researchers estimate that the global HBM market will reach $54.6 billion in 2026, up 58% from a year earlier.
The World Semiconductor Trade Statistics (WSTS) organization also forecasts the global semiconductor market to reach $975 billion this year, reflecting the continued expansion of AI-related investments.
A key driver of HBM demand is the growing adoption of application-specific integrated circuits (ASICs)—custom-designed chips optimized for specific AI workloads.
Major global technology companies and hyperscalers are increasingly developing their own AI chips instead of relying solely on graphics processing units (GPUs). Because these custom AI processors require large amounts of high-bandwidth memory, demand for HBM products has accelerated significantly.
Industry sources said Samsung continues to receive supply requests from both leading GPU manufacturers and hyperscale customers developing ASIC-based AI platforms.
Thanks to its expanding customer base, Samsung's overall HBM revenue is expected to more than triple this year compared with 2025.
Samsung attributes much of HBM4's success to its technological advantages.
The company applied a 4-nanometer advanced process to the base die of HBM4, becoming the first company to adopt such an advanced node in next-generation HBM products. The move has improved both performance and manufacturing stability.
Samsung's HBM4 delivers a data processing speed of 11.7 gigabits per second (Gbps), approximately 46% faster than the current industry standard, enabling AI systems to alleviate increasingly severe data bottlenecks.
Its data transfer capability has also been improved by approximately 2.7 times compared with the previous generation, while power efficiency has increased by around 40%, an important advantage for AI data centers seeking to reduce operating costs.
Industry experts believe Samsung's integrated device manufacturer (IDM) structure gives it a significant competitive advantage in the increasingly complex HBM market.
Samsung is the world's only semiconductor company with capabilities spanning logic chips, memory, foundry manufacturing and advanced packaging, enabling it to optimize every stage of production from chip design to final packaging.
As HBM technology becomes increasingly sophisticated and requires tighter integration among memory, logic and packaging technologies, Samsung's one-stop production capability is expected to become an even more important differentiator.
Analysts also view HBM4 as a major growth engine for Samsung's memory business, helping improve profitability by increasing the company's exposure to high-value AI semiconductor products.
"HBM4 is not just another memory product; it is a strategic component of the AI era's infrastructure," an industry official said. "Samsung's first-mover advantage in mass production has demonstrated its technological leadership and strengthened its position in the next-generation AI memory market."
Samsung is already accelerating development of HBM4E, an enhanced version of HBM4, aiming to further solidify its leadership in the fast-growing AI memory sector.
With global investments in AI infrastructure continuing to expand, the industry is closely watching whether Samsung's early success with HBM4 can reshape the competitive landscape of the global semiconductor market.
