SK hynix Priced a $28B US IPO Without a Roadshow.
No price range. No dinners in Boston. No greenshoe. The largest US listing since SpaceX cleared its opening auction on Nasdaq at $168.01 — and the process that got it there looked nothing like a normal book-build. Here is exactly how the mechanic worked.
When your stock already has a price, you don't need a range
A traditional US IPO invents a price from scratch. Bankers whisper a range, take indications of interest for two weeks, then set a number the night before the open. SK hynix skipped all of that for one reason: it is already public in Korea. Every trading day, KRX gives the underwriters something no domestic issuer has — a live, liquid, unarguable print.
So the "roadshow" became math. Take the KRX close, convert at spot FX, apply a small discount for illiquidity of the new US line, and you have a price. File it as a 424B4 the day before trading. Done.
72 hours from KRX close to Nasdaq cross
T-72h Korean close prints The Seoul close becomes the anchor. SK hynix trades every session on KRX — there is already a live price for the stock. No range needed. T-24h 424B4 lands Final prospectus filed with a single price ($149.00) rather than a range. The offering is sized off the KRX print, converted at spot FX, with a small discount. T-0h Cross at open The Nasdaq opening cross clears at $168 — a ~12.8% pop the sponsor never had to negotiate in a hotel ballroom. No greenshoe. No stabilization needed.Notice what is missing. No overnight book-build. No stabilization agent buying to defend the price. No 15% overallotment. The float is a 2.4% sliver of the company — deliberately small, because the whole point was to plant a US line, not to raise fresh capital.
Why the cross popped anyway
Even priced off a live tape, SKHY opened +12.76%. The reason is structural: US index funds and 401(k) mandates cannot hold KRX-listed lines. Once a US ticker exists, a mechanical bid arrives — one that did not previously have permission to touch the stock. That is the demand our Bellipo Demand Index was tracking all week: not sentiment, but eligibility.
We locked SKHY at ELEVATED before the tape moved.
Bellipo's Demand Index sealed SKHY at 82/100 the night before it opened. The dossier has the full mechanic: KRX anchor math, HBM revenue mix, float exposure, and the +12.76% day-one settle.

If you are TSMC, ASML, or Samsung watching this cross clear at +12.8% with no roadshow and no discount fight, you take notes. SKHY is not a one-off — it is a new template. Live-tape anchor pricing is how the next wave of foreign giants will plant US lines, and Bellipo will be scoring each one the night before.
