In this article, we look at the 10 Fastest Growing High-Bandwidth Memory Stocks to Buy.
High-bandwidth memory has become one of the more important bottlenecks in the AI semiconductor supply chain, as larger accelerators require faster, denser, and more power-efficient memory close to the processor. The shift is being driven by data-center AI spending rather than a broad consumer electronics recovery. TrendForce projected that AI server revenue would grow by more than 30% in 2026 and account for 74% of the overall server market value, while its HBM industry work has indicated continued market growth, with HBM3E remaining the main volume product and HBM4 adoption beginning.
The technology roadmap is also moving quickly. JEDEC’s HBM4 standard raises the interface to 2,048 bits and supports up to 2 TB/s of bandwidth per stack, giving chip designers more headroom for AI and high-performance computing workloads.
The supply chain response is showing up beyond memory makers. SEMI reported that global 300mm fab equipment spending is expected to rise 18% to $133 billion in 2026 and another 14% to $151 billion in 2027, reflecting stronger investment tied to AI chips, advanced packaging, and regional semiconductor capacity. The opportunity remains cyclical and technically demanding, but HBM has become a clearer growth pocket inside the broader memory and AI infrastructure markets.

We then selected 10 stocks that had the highest year-over-year revenue growth.
Why are we interested in the stocks that hedge funds pile into? The reason is simple: our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds. Insider Monkey’s quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 599.2% since May 2014, beating its benchmark by 372 percentage points (see more details here).
10. Marvell Technology, Inc. (NASDAQ:MRVL)
Marvell Technology, Inc. (NASDAQ:MRVL) is one of the fastest-growing High-Bandwidth Memory Stocks to buy. Marvell made its HBM-adjacent angle clearer on June 1, 2026, when it introduced the Teralynx T100, a 102.4 Tbps switch silicon product built for AI and cloud data centers. HBM solves the bandwidth problem near the accelerator, but large AI clusters also need fast, low-latency networking so that thousands of GPUs and XPUs do not sit idle waiting for data.
The company said the T100 was designed for AI training and inference workloads, with up to 25% lower power than competing solutions, under 1,000W typical power, and support for 512-port scale-out radix. The company also said GPU- and XPU-based racks are approaching 120KW, while switching and networking components can consume about 15% to 25% of rack power. The timing followed fiscal Q1 2027 results, in which revenue rose 28% year over year, driven by demand for AI-linked data infrastructure. That makes the product relevant to the same AI infrastructure buildout driving HBM adoption, even though Marvell is not a memory supplier.
Marvell Technology, Inc. (NASDAQ:MRVL) provides data infrastructure semiconductor solutions, including custom ASICs, optical connectivity, switches, storage, and networking products for cloud, enterprise, carrier, and AI data-center markets.
9. BE Semiconductor Industries N.V. (OTC:BESIY)
BE Semiconductor Industries N.V. (OTC:BESIY) is one of the fastest-growing high-bandwidth memory stocks to buy. The company strengthened its HBM-adjacent case on June 18, 2026, when it raised its long-term revenue target to €1.7 billion to €2.2 billion from €1.5 billion to €1.9 billion at its 2026 Investor Day. BE Semiconductor tied the higher target to improved order momentum since Q2 2025, rising demand for 2.5D AI-related datacenter and photonics applications, and new hybrid bonding use cases in logic, memory, and co-packaged optics. That is directly relevant to HBM because advanced AI chips increasingly depend on tighter integration between processors, memory stacks, and packaging technologies.
The update also followed a strong Q1 2026, when revenue rose 28.3% year over year to €184.9 million, and orders jumped 104.5%, helped by hybrid bonding, mobile, and photonics demand. BE Semiconductor is not a memory producer, but its bonding tools place it close to the manufacturing bottlenecks behind AI memory and advanced packaging.
BE Semiconductor Industries N.V. (OTC:BESIY) is a Netherlands-based semiconductor assembly equipment company that supplies die attach, hybrid bonding, packaging, plating, and related systems used in advanced semiconductor manufacturing.
8. ASMPT Limited (OTC:ASMVY)
ASMPT Limited (OTC:ASMVY) is one of the fastest-growing high-bandwidth memory stocks to buy. The company sharpened its HBM relevance on June 8, 2026, when it announced a repeat order for eight chip-to-wafer Thermo-Compression Bonding tools from a leading global integrated device manufacturer. ASMPT said the order followed the customer’s use of its Firebird TCB tools in high-volume manufacturing since 2024, giving the update more weight than a routine product showcase.
TCB is important in HBM and advanced AI packaging because memory stacks, logic dies, and substrates require precise, high-yield interconnects as chip designs move deeper into 2.5D and 3D integration. The update also fits ASMPT’s recent financial momentum. In Q1 2026, revenue rose 32.0% year over year to $507.9 million, while bookings increased 71.6% to $727.0 million. ASMPT remains an equipment supplier rather than a memory producer, but its bonding tools are closely tied to the manufacturing constraints of HBM, AI accelerators, and chiplet-based packaging.
ASMPT Limited (OTC:ASMVY) is a Singapore-headquartered semiconductor and electronics manufacturing equipment company that supplies advanced packaging, bonding, assembly, surface-mount technology, and related solutions.
7. Advanced Micro Devices, Inc. (NASDAQ:AMD)
Advanced Micro Devices, Inc. (NASDAQ:AMD) is one of the fastest-growing high-bandwidth memory stocks to buy. The company added a memory-focused AI infrastructure angle on June 15, 2026, when it acquired MEXT, a startup developing AI-driven memory optimization technology. AMD said MEXT’s software is designed to make flash behave more like DRAM, expanding usable memory capacity while maintaining performance and efficiency. That does not make AMD an HBM producer, but it does put the deal squarely within the same bottleneck driving HBM demand: AI models, analytics, virtualization, and high-performance computing workloads increasingly need larger, faster memory pools.
AMD said the acquisition expands its AI portfolio and should help customers reduce the total cost of ownership, improve resource utilization, and scale workloads more effectively. The update also follows AMD’s Q1 2026 results, where revenue rose 38% year over year, and Data Center revenue increased 57%, helped by EPYC demand and continued Instinct GPU shipments.
Advanced Micro Devices, Inc. (NASDAQ:AMD) designs CPUs, GPUs, adaptive computing products, and data-center accelerators for cloud, enterprise, gaming, embedded, and AI infrastructure markets.
6. Taiwan Semiconductor Manufacturing Company Limited (NYSE:TSM)
Taiwan Semiconductor Manufacturing Company Limited (NYSE:TSM) is one of the fastest-growing high-bandwidth memory stocks to buy. The company’s latest relevant financial update came on June 10, 2026, when it reported May revenue of NT$416.98 billion, up 30.1% year over year, while January-through-May revenue rose 30.0% to NT$1.96 trillion. The HBM link is not through memory production, but through TSMC’s advanced logic and packaging role in AI accelerators. Its CoWoS platform is designed for ultra-high-performance computing applications such as AI and supercomputing, and TSMC says CoWoS-S can integrate logic chiplets with HBM cubes over a silicon interposer.
That makes TSMC one of the central bottleneck suppliers for GPUs, custom AI chips, and other processors that need HBM close to the compute die. The latest revenue growth, therefore, fits the same demand cycle, pushing HBM adoption: larger AI models, denser accelerator clusters, and rising need for advanced packaging capacity rather than ordinary consumer-chip replacement.
Taiwan Semiconductor Manufacturing Company Limited (NYSE:TSM) is a Taiwan-based semiconductor foundry that manufactures advanced chips and provides process and specialty technologies, as well as advanced packaging services.
While we acknowledge the potential of TSM to grow, our conviction lies in the belief that some other AI stocks hold greater promise for delivering higher returns and have limited downside risk.
