South Korea’s aerospace sector is experiencing a remarkable surge, fueled by global milestones and ambitious local investment. The past week has seen a flurry of activity in both the domestic stock market and the country’s expanding aerospace industry, as international successes and corporate strategies converge to create what many are calling a new era for space-related business in Korea.
At the center of this excitement is the much-anticipated initial public offering (IPO) of SpaceX, the American space giant led by Elon Musk. According to Digital Today, SpaceX has confidentially filed a preliminary review application with the U.S. Securities and Exchange Commission, aiming for a listing as early as June 2026. The company’s targeted valuation is a staggering $2 trillion (about 3,022 trillion won), positioning it to set records for capital raised in an IPO. Nasdaq has even revised its listing requirements, scrapping the minimum public float ratio and shortening the index inclusion waiting period to just 15 trading days, all in an effort to attract SpaceX.
This announcement, combined with the successful launch of NASA’s Artemis II crewed lunar mission on April 2, 2026, has sent ripples through the Korean stock market. Investors have rushed to snap up shares in aerospace-linked stocks and exchange-traded funds (ETFs), anticipating a windfall from the sector’s newfound momentum. On April 3, the KODEX US Aerospace ETF closed up 7.92% from the previous day, while the 1Q US Aerospace Tech ETF jumped 7.02%. Individual stocks with direct or indirect ties to SpaceX, such as Mirae Asset Venture Investment, Mirae Asset Securities, and Aju IB Investment, all saw notable gains. Mirae Asset Venture Investment rose 6.60%, Mirae Asset Securities was up 2.44%, and Aju IB Investment increased by 0.57%.
Other key players in Korea’s aerospace value chain, including Hanwha Aerospace, Hyundai Rotem, and Satrec Initiative, also enjoyed strong performances. The rally was further buoyed by news that domestic defense companies like Hanwha Aerospace and Hyundai Rotem have added the space industry as a new business objective, aiming to make it a core driver of long-term growth. As Digital Today reports, satellite system developers such as Satrec Initiative and Hanwha Systems are now seen as direct beneficiaries of the current space boom, with the market spotlight firmly on them.
SpaceX’s influence is not just indirect. Korean company Spear has signed a long-term supply contract with SpaceX worth about 1.5 trillion won, and this year alone is set to deliver approximately 77.2 billion won in goods. Meanwhile, Mirae Asset Securities has emerged as a standout beneficiary, having made early investments in both SpaceX and xAI. In 2025, the firm posted a jaw-dropping 2,074.8% year-on-year increase in profits from its fair value through profit or loss (FVPL) securities segment, totaling 2.62 trillion won, thanks in large part to these investments.
The space theme has become so popular that fund managers are scrambling to launch new ETFs. This month, Korea Investment Trust Management will debut its ACE US Space Tech Active ETF, and Shinhan Asset Management will list the SOL US Aerospace Top 10 ETF. Yet, the frenzy has not been without controversy. Hana Asset Management recently had to retract plans to indirectly include unlisted SpaceX shares in its 1Q US Aerospace Tech ETF after criticism from the Financial Supervisory Service, apologizing to investors and withdrawing its total return swap (TRS) contract.
Experts are quick to warn that while the allure of space investments is strong, investors should be cautious of short-term hype and focus on companies with real, sustainable benefits. Kim Jae-im, a researcher at Hana Securities, told Digital Today, “This year, with SpaceX going public and various U.S. government space projects underway, major U.S. space industry stocks will become bona fide global investment targets.” She added, “Geopolitical volatility, such as the war in Iran, is a factor to consider, but given the strength of the space industry theme over several years, there are plenty of good opportunities to be found.”
Against this backdrop, Hyundai Rotem is making bold moves to reposition itself as a major aerospace player. Traditionally focused on rail and defense, the company is now expanding aggressively into future-oriented industries such as aerospace and hydrogen. According to Today News, Hyundai Rotem plans to invest a total of 1.8 trillion won in research and development and facilities for aerospace and hydrogen projects between 2026 and 2028—a figure more than triple its 5,031 billion won investment from 2023 to 2025. The company is funding these investments through its own cash flow and reserves, rather than external borrowing.
The investment blueprint is broad and ambitious. It includes unmanned ground weapon systems, autonomous control technologies, expansion of the Seosan Aerospace Center in South Chungcheong Province, and the development of key hydrogen technologies. Perhaps most notably, Hyundai Rotem, in partnership with Jeollabuk-do Province and Muju County, will spend about 300 billion won by 2034 to build a comprehensive aerospace production base in Muju. This new facility will focus on research and production of next-generation propulsion systems, including methane engines.
January 2026 marked a turning point for Hyundai Rotem, as the company established an Aerospace Systems Team within its Aerospace Development Center and promoted Namgoong Hyuk-joon, the leader behind its 35-ton-class methane engine project, to director. In March, the company’s annual business report officially identified aerospace as a core pillar of its new business strategy. The report stated, “The Defense Solutions Division is shifting its business structure toward the future, focusing company-wide capabilities on new areas such as robotics, manned-unmanned teaming (MUM-T) systems, and aerospace.”
Hyundai Rotem’s technical focus is on methane engines, which offer clear advantages over traditional kerosene-based engines, especially for reusable launch vehicles due to their lower soot output. The company is working with Korean Air in a consortium to design methane engines and combustors by 2030, with national projects helping to accelerate development. Alongside this, Hyundai Rotem is developing advanced propulsion systems like supersonic ducted ramjet engines and hypersonic dual ramjet engines, aiming for dual-use applications in both missiles and space launch vehicles. The company has already demonstrated its prowess in the HyCore (Korean hypersonic vehicle) project, achieving Mach 6 speeds in test flights.
“The methane engine is core technology for reusable launch vehicles and a long-term project for the era of private space transportation,” a Hyundai Rotem official told Today News. “Research and development on ramjet engines is also progressing smoothly.”
For now, most of Hyundai Rotem’s aerospace work is at the research and development stage, not yet reflected in sales. But the company is laying the groundwork for future commercialization, focusing on building a solid technology base. “We’ve been accumulating aerospace technology for about 30 years, but it was mostly maintenance-level until recently,” a company spokesperson explained. “Now, with its selection as a future growth engine, we’re making significant investments and expanding the business in earnest.”
Hyundai Rotem’s leadership is keenly aware of the stakes. CEO Lee Yong-bae declared, “We will secure technological competitiveness in future industries such as hydrogen, unmanned systems, AI, and aerospace, and quickly commercialize them to build a foundation for sustainable growth. We will make 2026 the first year of our leap from the ground to space.” In February 2026, Lee was also elected president of the Korea Space Technology Promotion Association, strengthening the company’s industry ties and policy connections.
The global shift toward private space enterprise—sometimes called the "NewSpace" movement—has created a fertile environment for Korean companies to enter the market, especially as they secure key technologies like launch vehicle engines and propulsion systems. Hyundai Rotem’s aggressive investment and strategic positioning are widely seen as a response to this rapidly evolving landscape.
As Korea’s aerospace industry rides the tailwinds of international breakthroughs and local innovation, investors and industry watchers alike are keeping a close eye on the next phase. The sense of anticipation is palpable: will Korean companies ride this wave all the way to the stars, or will the sector’s early promise require more patience to realize?
