Wall Street AI IPO Honeymoon Phase Ends as All Four Key Names Come Under Pressure

SK Hynix, SpaceX, Cerebras, and CoreWeave have all pulled back sharply after post-listing euphoria faded, as the market shifts from sentiment-driven premiums back to fundamentals and demand durability.
SK Hynix: the biggest-ever foreign U.S. listing — so why did it drop in week one?
SK Hynix raised $26.5 billion via Nasdaq ADRs — American depositary receipts, essentially proxy shares traded in the U.S. — setting a record for any foreign company listing stateside.
Shares opened at $170 on day one but closed Monday at $152.35, a 9% single-day drop, barely 2% above the offer price.
Back in Korea, the local-listed stock fell as much as 15% that day — a record single-session decline — before rebounding 4% on Tuesday.
This means → doubts about chip-demand sustainability hit the tape all at once ahead of earnings season. No listing, however large, is immune to a sentiment unwind.
SpaceX: why did retail investors get trapped on entry?
After completing what has been called the largest IPO ever, SpaceX stock peaked 58% above the offer price on day three.
It then drifted lower, closing Monday at $139.14 — just above the $135 offer price, below the $150 first-day open.
This means → early institutional and insider holders still sit on gains, but retail buyers who entered after the listing are most likely underwater. In plain terms = the money was made by those already on the bus; latecomers became the exit liquidity.
Cerebras and CoreWeave: what happened after the first-day doubles?
AI chip maker Cerebras surged as much as 109% on its debut, then shed nearly 50%, leaving the stock stranded between its offer price and first-day open.
Data-center operator CoreWeave traced an even more extreme arc: a muted March 2025 debut, then a nearly 400% rally to a mid-June 2025 peak, followed by a roughly 55% slide from that high.
This means → timing was everything. Early investors who sold near the peak locked in outsized gains; those who bought at the top are sitting on heavy losses.
What pattern do all four names share?
The four stocks followed a strikingly similar script: sentiment-fueled premiums on debut, then a broad pullback once the excitement faded, with the market reverting to fundamentals.
This reflects a core tension in AI new issues: valuations are anchored to the assumption that AI demand will keep growing at a high rate. The moment that assumption wavers, the premium gets squeezed out.
In plain terms = AI earnings season is approaching. Whether these stocks can back their valuations with actual results is the key test of whether this correction is over.
