SK Hynix priced 177.9 million American depositary receipts at $149 on Thursday night. The stock opened at $170 on the Nasdaq Friday morning, a 14% pop. The $26.5 billion raise is the largest US share sale ever completed by a foreign company, topping the record Alibaba set in 2014. Demand ran more than seven times the shares available. The debut valued the company around $1.27 trillion, which slots it in as the 11th largest name on US markets, just above Eli Lilly.
That alone would be a story. Here is why it matters more to options traders: Reuters reported Friday, citing sources familiar with the plans, that exchanges including Cboe and Nasdaq expect to list options on the new ADRs two business days after the debut. Count it out and contracts could be trading Tuesday, July 14.
New listings normally make traders wait. This one will not.
The mechanics first
Get the ticker right before Tuesday. The ADRs trade in when-issued mode under SKHYV through Friday. Regular-way trading begins Monday, July 13 under SKHY, per Nasdaq's listing notice. Each ADR represents one tenth of a Seoul-listed common share. The offering itself closes July 14, and the newly issued shares underlying the ADRs list on the Korea Exchange July 29.
Why these options are different
SK Hynix is not just another semiconductor name getting a US listing. It is the world's leading producer of high-bandwidth memory, the stacked DRAM that feeds Nvidia's AI accelerators. The company's own SEC filing puts its HBM share at 56.4%. Nvidia is the biggest HBM buyer, and the two companies announced a multiyear partnership in June when Jensen Huang visited Seoul.
Until Friday, a US options trader who wanted exposure to AI memory demand had a short menu: Nvidia, AMD, Micron, Broadcom, or a sector ETF like SOXX. SKHY adds the dominant supplier of the memory layer itself. If volume builds, SKHY slots directly into the core AI options complex.
What to expect when trading opens
New high-profile option listings follow a pattern. Implied volatility prints high, markets start wide, speculative call flow shows up early, and dealer hedging of that flow can push the stock around. Expect all of it here. The debut also lands after a rough stretch for chip stocks, so the first prints in SKHY vol will double as a live reading on how much fear or greed is left in the AI trade.
The freshest comp is SpaceX. Its options launched last month and drew record volumes almost immediately, proof that a hot new name can go from zero to one of the most active options boards on the tape in days.
One more wrinkle. With no trading history, IV rank and IV percentile will be useless on this name for months. There is no one-year range to compare against, so every read on whether SKHY vol is rich or cheap has to come from comps like Micron instead.
Since nobody can quote SKHY implied volatility yet, we built a tool for the wait. Set an IV level and see what the market would be pricing in. That expected move is what an at the money straddle is priced to capture. When real quotes print Tuesday, check your guess.
