A practicing semiconductor engineer's daily read on global silicon news:
An AI memory supercycle that rewired both KOSPI and global capex allocation in a single session — Samsung crossed $1 trillion, KOSPI ripped +6.45% to 7,384.56, and SpaceX/Tesla filed for a $119B Intel 14A 'Terafab' in Texas.
Chase's Take — Honest one-liner: this was the day memory beat PPA again. Samsung and Hynix posting 70%+ chip operating margins in 1Q26 isn't a cycle bounce — it's the LTA model (3-5 year terms, 10-30% prepayments) shifting inventory-turn risk onto the buyer side, which kills the spot cycle and steps the contract floor up. Second — SpaceX picking Intel 14A is the largest capital bet on 'Intel Foundry doesn't die.' Apple-18A-P, Tesla/SpaceX-14A, Google-EMIB. I wonder what face the analysts who declared 'Intel 18A: zero customers' a year ago are wearing today. Third — Goldman taking AMD from $240 to $450 in one shot is narrative beating numbers; it gets priced in before MI400 even launches. Watch-points next quarter: SK hynix M15X first cleanroom topping out in May → pilot → November HVM, and the moment Samsung 2nm crosses the 60% yield threshold for production. And KOSPI 7,400 may be the start of foreign passive flows draining Japan weight into Korea — if two memory tickers push the KOSPI weight past 43%, the index itself becomes a short-duration hedge on the memory cycle.
