What happened

SK Hynix (000660.KS) filed to raise up to $29.4B (₩45.45T) via a Nasdaq ADR listing — ~17.79M new American Depositary Shares — with trading expected to start ~July 10, 2026. Confirmed across Bloomberg / CNBC / Reuters (RTE) / Tom's Hardware on 2026-06-24 (originally surfaced via @IPONewsroom_).

• Scale: largest-ever US listing by a Korean firm; potentially the biggest-ever ADR listing, surpassing Alibaba's $25B 2014 debut. At the top end, among the top-5 share sales of all time (comparable to Saudi Aramco's 2019 record).
• Use of proceeds: build advanced memory fabs in South Korea + purchase chipmaking equipment, explicitly including ASML EUV scanners.
• Underwriters: Bank of America, Citigroup, Goldman Sachs, JPMorgan.
• Backdrop: SK Hynix +~300% in Seoul YTD, just passed Samsung as Korea's most valuable company; controls ~57% of the HBM market (the memory inside NVIDIA AI GPUs). Filing lands days after the KOSPI −9.9% single-day selloff (2026-06-23, captured via @amitisinvesting) and the Micron–Anthropic strategic partnership (2026-06-22).

Why it matters

Routed to two active tracks; this is a captured external event, not yet a thesis shift — the read-throughs below are the durable hooks:

• memory-supercycle (primary): the HBM monopolist monetizing the cycle at a record valuation is a direct structural-tightness datapoint. The Roundhill Memory ETF ($DRAM) and the new 2x daily $RAM are the listed vehicles; MU is the US-comp read-through; ASML is levered via the stated EUV-tool proceeds. Memory-ETF press (Benzinga/Yahoo) reported the DRAM ETF bid up premarket on the news — web-reported, not workspace price truth; confirm against a scan bucket before any price conclusion.
• spacex-ipo-liquidity-event (AI-mega-IPO supply): a ~$29B raise stacks onto the SpaceX/Anthropic mega-IPO issuance wave — incremental primary-equity supply competing for the same dollars, feeding the issuance-surge / liquidity-drain frame.

Ticker-identity note: SK Hynix is research-only foreign — Korean primary 000660.KS, German proxy HY9H.F (per the memory-supercycle laggard-vs-MU note); the new US ADR ticker is not yet assigned. Keep SK Hynix out of watchlist/trade rows until the ADR ticker is known and explicitly authorized; the tradeable exposures we track are MU / DRAM / RAM / ASML.

Follow-ups (not yet done): capture the SK Hynix ADR ticker once assigned and decide a security-family row in _securities.json; on July 10, confirm pricing/first print (intraday ≠ close).
