Samsung to mass-produce HBM4 this month; shares jump on Nvidia link

Summary：Report says Samsung will ramp HBM4 later this month and may ship after Lunar New Year. HBM4 is expected for Nvidia’s next-gen Vera Rubin AI platform as Samsung narrows the gap with SK Hynix.

On Monday, during trading on the Korean stock market, Samsung Electronics saw a strengthening of its stock price. This was driven by industry reports suggesting that the company plans to start mass production of the next-generation high-bandwidth memory, HBM4, later this month, with shipments expected to begin after the Lunar New Year.

HBM4 Mass Production Rumor: Stock Price Rises Over 5% Intraday

According to industry sources, Samsung's HBM4 is positioned as the sixth generation high-bandwidth memory product. Following the news, Samsung's stock listed in Seoul surged over 5% at one point, reaching around 168,700 KRW.

Key Application: Targeting NVIDIA's Vera Rubin Platform

The market is highly sensitive to the progress of HBM4, mainly due to its potential clients and application scenarios—HBM is a crucial component of AI accelerators. The report mentions that the HBM4 is expected to be used in NVIDIA's GPUs, aligning with the development pace of its next-generation AI accelerator/platform (Vera Rubin); meanwhile, it is also reported that the supply of test samples is increasing.
NVIDIA, in its official technical breakdown, also noted that the Rubin GPU will adopt HBM4, achieving significant improvements in memory interface and bandwidth over the previous generation, further reinforcing the market consensus of "advanced HBM = AI computing power bottleneck."

Competitive Landscape: Dominance of HBM3E; Samsung Accelerates to Catch Up with SK Hynix

Currently, the HBM market mainly revolves around HBM3E, with supply chain and yield capabilities directly determining the speed of customer adoption. In recent years, Samsung has been striving to narrow the gap with SK Hynix in the advanced HBM field, and achieving the HBM4 mass production milestone would be seen as critical progress in its catch-up effort.

Future Outlook: Certification, Shipments, and Major Client Adoption

There are three main short-term observation points:

Whether mass production is on schedule (including the post-New Year shipment progress);
Progress in major client adoption (including expansion of test samples and orders);
The impact of the transition between HBM4 and HBM3E on price and market share.
