As of October 28, 2026, the US semiconductor build-out is no longer a policy argument — it is a construction schedule. Samsung Electronics is preparing its Taylor, Texas foundry for operation within the year and plans a second plant there in November, while SK Hynix is building a $3.87 billion advanced-packaging site in West Lafayette, Indiana. Both describe targets, not completed output.
Key Takeaways
- ■ Samsung readies its Taylor fab1 for year-end operation and plans a November start on fab2, citing a 250,000 sq m footprint and a 2030 production target.
- ▼ SK Hynix’s Indiana plant carries two milestones tracked separately by outlet: operation targeted for the second half of 2028, per Newspim and NewsWhopLus, and mass production for the third quarter of 2029, per iNews24.
- ▲ Korean suppliers are forecast to follow the plants overseas, though most reported talks remain feasibility reviews or NDAs.
- ■ Samsung closed up 4.23% and SK Hynix up 5.18% on Oct 27, 2026, a move Yonhap read as reflecting improved chip sentiment.
Why the Taylor startup carries more than one reading
Samsung is preparing to operate Taylor fab1 within the year, iNews24 reported. ZDNet Korea went further, describing the site as a US foundry mass-production line for the company. John Taylor, who oversees both Texas sites, told the Austin American-Statesman that fab1 is on track for its year-end goal. Capacity figures diverge: ZDNet Korea put Taylor’s design maximum at 20,000 wafers a month, Electronics Weekly cited a potential 50,000, and an equipment order sized for 6,000 wafers a month of 2-nanometer capacity was reported by Tweaktown, which noted Samsung has not confirmed it.
What SK Hynix is building in Indiana
SK Hynix broke ground in West Lafayette on August 27, 2026, on a plant that stacks DRAM dies vertically into HBM, the high-bandwidth memory used alongside AI accelerators. Newspim put the total at $3.87 billion; state support was promised at up to $712.18 million, while NewsWhopLus reported a federal grant of up to $458 million under the CHIPS Act plus a loan of up to $500 million. Milestones split by outlet: Newspim and NewsWhopLus target operation in the second half of 2028; iNews24 reported cleanroom build-out through October 2028 and mass production for the third quarter of 2029.
Korean suppliers weigh a move alongside the fabs
Global Economic forecast that Hansol Chemical, Dongjin Semichem and Wonik IPS will extend local supply chains as Samsung’s US 2-nanometer line takes shape. iNews24 reported that talks with domestic suppliers remain early, still feasibility reviews or NDAs, with actual orders and revenue depending on construction timing and customer supplier selection.
What drove the Oct 27 rally
Samsung closed at 222,000 won on October 27, up 4.23%, and SK Hynix at 1,341,000 won, up 5.18%, with foreigners net selling 41 billion won of SK Hynix. SK Square, which owns about 20% of SK Hynix, rose 7.67%. Yonhap attributed the move to Anthropic’s IPO filing, reportedly targeting a valuation of up to $2 trillion, which it said lifted the Philadelphia semiconductor index 2.82% and improved chip sentiment; a Daishin Securities analyst told the agency the S-1 disclosure confirmed AI monetization potential.
SK Square and SK had risen 11.83% and 9.34% by 10:52 a.m. that day, an intraday snapshot, not a closing print. The same report carried a KB Securities analyst’s forecast of up to 40 trillion won in further SK Hynix shareholder returns — a broker projection, not a company plan.
