Gotrade News - SK Hynix broke ground on August 27 on a more than $4 billion advanced packaging plant at Purdue Research Park in West Lafayette, Indiana, its first high-bandwidth memory production base on US soil. According to SK hynix's official announcement, the site will open its cleanroom by October 2028 and begin mass production of next-generation HBM in the second half of 2029.
The timing matters because the memory that feeds AI accelerators is in the middle of a demand supercycle, and the companies that supply it are printing record margins. For US-listed investors, the read-through runs straight to memory maker Micron Technology (MU) and to the AI chip buyers, led by NVIDIA Corp. (NVDA), that cannot get enough of it.
Key Takeaways
SK Hynix committed over $4 billion to an Indiana HBM packaging fab, with mass production slated for the second half of 2029.
SK Hynix held a 58% HBM market share in Q1 2026 and posted a 76% operating margin in its latest quarter.
Its CEO said he sees a memory shortage persisting through the end of 2030, with no clear signs of a downturn.
Micron is the accessible US-listed way to own the memory theme, while Nvidia and Broadcom anchor the demand side.
Why a $4 Billion HBM Base Is Landing in Indiana
The Indiana fab will take advanced wafers made in South Korea and handle packaging and testing in the US, the most complex and value-added step in building HBM. As reported by Investing.com, the plant is expected to run next-generation HBM4E and reach volume production in the third quarter of 2029, supported by $458 million in CHIPS Act grants and up to $500 million in loans finalized in December 2024. SK Hynix projects roughly 7,000 direct and indirect jobs and signed a research memorandum with Purdue University on advanced packaging.
Chief Executive Kwak Noh-Jung framed the investment as a long-term bet on US demand, saying the company will "become the most trusted partner in the U.S., where top-tier customers, R&D capabilities, and partners align." He has separately said he expects the current memory shortage to persist through the end of 2030, with "no clear signs of a memory downturn."
The supplier economics behind the buildout are extraordinary. Per The Motley Fool, SK Hynix held a 58% HBM share in the first quarter of 2026 (Counterpoint Research), reported second-quarter revenue of 79.3 trillion won (about $55 billion), up 257% year over year, and posted a 76% operating margin. The company began mass shipments of HBM4 during the quarter, sampled next-generation HBM4E, and locked long-term agreements with about 10 customers, including a supply arrangement tied to Nvidia. Memory prices kept climbing, led by HBM and AI-server DRAM.

How US-Listed Investors Access the Memory Supercycle
Because SK Hynix and Samsung trade in Seoul, Micron Technology (MU) is the most direct US-listed way to own the memory upturn, competing in the same HBM market alongside the two Korean leaders. On the demand side, NVIDIA Corp. (NVDA) is the largest HBM buyer, while Broadcom (AVGO) and foundry Taiwan Semiconductor (TSM) capture the surrounding AI infrastructure spend.
Semtech's 1.6T CopperEdge Ramp Rides the Same Wave
The supercycle is widening beyond memory into the plumbing that connects AI clusters. According to Semtech's fiscal second-quarter results, the connectivity chipmaker posted revenue of $342 million, up 33% year over year, on a record $100 million of data center sales, up 91% from a year earlier. Its CopperEdge active copper cable and linear equalizer products are moving toward 3.2T designs, and management guided for data center revenue to grow about 160% year over year in the current quarter as 1.6T deployments ramp.
The signal across the stack is consistency. Every layer of AI infrastructure, from HBM to interconnects, is reporting demand that outruns supply, and the capacity being poured now, like SK Hynix's Indiana fab, will not arrive until 2029. That gap is what keeps pricing power in the hands of the suppliers.
