5 Fastest Growing High-Bandwidth Memory Stocks to Buy

In this article, we will list the 5 Fastest Growing High-Bandwidth Memory Stocks to Buy. Please visit 10 Fastest Growing High-Bandwidth Memory Stocks to Buy if you’d like to see an extended list.

We screened high-bandwidth memory and HBM-adjacent semiconductor stocks, including memory producers, AI accelerator companies, advanced packaging firms, and semiconductor equipment suppliers with direct exposure to the HBM supply chain. We then selected stocks that had the highest year-over-year revenue growth.

5. Broadcom Inc. (NASDAQ:AVGO)

Broadcom Inc. (NASDAQ:AVGO) is one of the fastest-growing high-bandwidth memory stocks to buy. The stronger topic fit occurred on June 9, 2026, when Broadcom, Apollo, and Blackstone launched the AI XPV Platform to support more than 20 gigawatts of AI compute capacity, leveraging Broadcom’s XPUs and networking solutions through 2028.

The platform starts with a $35 billion tranche for more than 1 gigawatt of Anthropic compute infrastructure expected to begin deployment at Fluidstack sites in mid-2026. Broadcom is not an HBM supplier, but custom AI XPUs typically depend on high-bandwidth memory and high-speed networking to keep large training and inference clusters from becoming data-starved. The update also lands soon after Broadcom’s fiscal Q2 2026 report, where revenue rose 48% year over year to $22.2 billion and AI semiconductor revenue grew 143% to $10.8 billion. The LSEG VMware renewal is useful software news, but the XPV platform is much closer to the HBM-driven AI hardware cycle.

Broadcom Inc. (NASDAQ:AVGO) designs and supplies semiconductor and infrastructure software products, including custom AI accelerators, networking chips, storage connectivity, broadband components, wireless products, and VMware-based infrastructure software.
