SKHY or SPCX: Which Stock Should You Bet on After Impressive US Debut?
Read MoreHide Full Article
Key Takeaways
SKHY has outperformed SPCX since their respective IPOs and appears more attractive on a forward P/S basis.
SK Hynix is benefiting from strong HBM demand, AI data-center growth and its role as an NVIDIA supplier.
SKHY plans a $28.7B accelerated buyback and aims to return over 50% of 2025-2027 free cash flow.
South Korean memory-chip giant SK Hynix (SKHY - Free Report) made a highly impressive Wall Street debut in July. Space Exploration Technologies Corp. (SPCX - Free Report) , a vertically integrated technology company developing infrastructure across space, connectivity and artificial intelligence, completed its blockbuster initial public offering a month earlier.
However, both stocks have experienced considerable volatility since their respective debuts. As the initial enthusiasm subsides, the shares are undergoing a broad correction, with early investors locking in profits. Against this backdrop, let us compare the two companies to determine which stock currently presents the more compelling investment opportunity.
The Case for SpaceX
The Elon Musk-led aerospace and communications giant raised an unprecedented $75 billion through its blockbuster IPO in June. From transforming launch services with reusable rockets to operating the world’s largest satellite broadband network, SpaceX aims to reinforce its position as the leading player in the rapidly growing space economy.
SpaceX has reshaped the launch industry through its reusable Falcon 9 rockets, substantially lowering launch costs and increasing mission frequency. The company now carries out more annual launches than any global rival, giving it a dominant position in the commercial launch market.
The company is also prioritizing AI monetization to support its next phase of growth. SpaceX seeks to become a vertically integrated AI infrastructure provider by bringing advanced AI models, large-scale computing capabilities and satellite connectivity under a single platform. Its AI operations combine Grok, X, cloud services and Colossus infrastructure with the company’s broader launch and connectivity ecosystem.
SpaceX recently secured $6.7 billion in cloud-services revenues over a six-month period beginning in October. Its pending $60 billion acquisition of Cursor is expected to close in the third quarter of 2026, adding enterprise software distribution and engineering integration capabilities. The acquisition would also bring a widely used developer platform that could complement SpaceX’s expanding technology portfolio.
The company intends to begin deploying AI compute satellites as early as 2028, effectively establishing space-based data centers capable of providing large-scale computing capacity. This initiative builds on SPCX’s leadership in satellite deployment while addressing the growing demand for AI computing resources. Alongside its satellite plans, SpaceX continues to expand the Colossus data-center platform, further strengthening its AI infrastructure position.
However, SpaceX is simultaneously scaling several capital-intensive platforms. The company is investing heavily in COLOSSUS, COLOSSUS II, Grok, enterprise solutions, computing services and future orbital AI infrastructure. This strategy could generate a cost advantage if its computing, energy and launch assets integrate as intended. Until then, the AI push introduces uncertainty surrounding margins, capital requirements and the quality of consolidated earnings.
The Case for SK Hynix
On July 14, 2026, the South Korean company’s shares reached a record high of $194.80 before closing at $193.92, more than 27% above the previous day’s close. SK Hynix raised approximately $26.5 billion through the offering, with its American depositary receipts, or ADRs, priced at $149. This made it the largest-ever U.S. IPO by a foreign company. Like SpaceX, SK Hynix has since faced considerable volatility, with steep declines followed by brief recoveries.
SK Hynix continues to gain from soaring demand for high-bandwidth memory and advanced storage chips, both of which are essential components of AI infrastructure. The rapid expansion of AI data centers has created a global shortage of memory products, boosting demand across sectors ranging from cloud computing to consumer electronics.
As a major supplier of AI memory chips to NVIDIA (NVDA - Free Report) , SK Hynix is well positioned to capitalize on the AI boom. Building on its relationship with NVIDIA, the company is expanding manufacturing capacity to address increasing demand generated by the continuing global AI investment cycle.
SK Hynix holds a strong position in the high-bandwidth memory, or HBM, market. This leaves it favorably placed as agentic AI drives greater memory requirements. Its early leadership in HBM provides a meaningful competitive advantage. Meanwhile, the rapid expansion of AI data centers has created a worldwide memory-chip shortage, lifting demand across industries from cloud computing to consumer electronics. The company could also gain from supportive policies in South Korea.
SK Hynix shares have recently received support from the announcement of an accelerated 40 trillion won, or $28.7 billion, share-repurchase and cancellation program. The company also intends to return more than 50% of the cumulative free cash flow generated between 2025 and 2027 to shareholders.
