SpaceX submitted a confidential IPO application to the SEC on April 1, 2026, which was independently confirmed on the same day by Bloomberg, CNBC, Reuters, and the Wall Street Journal.
The initial public offering (IPO) of SpaceX has become a reality.
On April 1, 2026, SpaceX officially submitted a confidential IPO application to the U.S. Securities and Exchange Commission (SEC). This fact, initially reported by Bloomberg, was simultaneously confirmed through independent sources on the same day by CNBC, Reuters, and the Wall Street Journal.
This IPO is not a simple listing event. It marks the first time that a complex technology company—evolving from rocket manufacturing to global satellite internet services, U.S. government defense and space contracts, and artificial intelligence company acquisitions—is entering the public market.
There are three reasons why corporate investors and asset management professionals in Korea must pay attention to this IPO.
They are the possibility of direct participation in the listing and its constraints, indirect exposure channels through the domestic ETF market, and the practical ripple effects of SpaceX's growth on Korean industries.
SEC Confidential Filing: An Officially Confirmed Starting Point
The confidential filing system is a procedure that allows a company to undergo preliminary SEC review without disclosing its financial information to the general public.
Under U.S. regulations, SpaceX must file a complete public prospectus (S-1) on the SEC's official EDGAR filing system at least 15 days before the start of the IPO roadshow, and this moment will be the first time SpaceX's actual financial status is officially disclosed.
According to Bloomberg and CNBC, the valuation target set by SpaceX is $1.75 trillion, with a fundraising target of up to $75 billion. However, these figures have not been officially announced directly by SpaceX and are subject to change prior to the publication of the public S-1.
To date, the largest IPO in history was Saudi Aramco's fundraising of $29.4 billion in 2019, and SpaceX's target significantly exceeds this.
xAI Merger: Transaction Structure Confirmed by CNBC via Documents
On February 2, 2026, Elon Musk officially announced the merger of SpaceX and xAI. CNBC directly reviewed the transaction documents, and Bloomberg and Reuters independently confirmed them.
As confirmed by CNBC through the documents, the transaction was structured as an all-stock swap, with SpaceX valued at $1 trillion and xAI valued at $250 billion, bringing the combined valuation to $1.25 trillion. The stock exchange ratio was set at 0.1433 shares of SpaceX stock per 1 share of xAI stock.
Through this merger, SpaceX's asset scope has expanded significantly.
In addition to existing Falcon 9, Falcon Heavy, and Starship launch assets and the Starlink satellite internet service, xAI's Grok artificial intelligence model and social platform X (formerly Twitter) have been incorporated under SpaceX.
Musk directly stated the purpose of the merger in a public blog post at the time of the merger announcement. The goal is to build the "most ambitious vertically integrated innovation engine spanning AI, rockets, space-based internet, and social media," and he presented "building orbital data centers" as the main reason for the merger. However, orbital data centers are not currently operating businesses but rather concepts presented as the strategic direction of the merger, and investors must clearly recognize that this item is a future plan.
Meanwhile, in March 2026, Musk posted directly on the social platform X: "xAI was not built right from the start, so we are rebuilding it from the ground up." This is a public statement by Musk himself, suggesting that the market's questions about the current completeness of the AI assets could act as a core variable during the IPO process.
Governance Structure: The Actual Scope of Influence Held by General Shareholders
SpaceX has adopted a multi-class voting stock structure.
According to CNBC, under this structure, Elon Musk holds approximately 42% of SpaceX's equity while exercising approximately 79% of the total voting power. Shares allocated to general investors through the public offering are granted only standard voting rights, meaning they do not hold substantial influence over management direction.
While similar to the founder governance structures utilized by major U.S. tech companies like Google and Meta when going public, analysis by the KBR Business Research Institute shows that the concentration on the founder's side is more extreme than typical dual-class voting structures, and debate is already underway in the market.
Korean institutional and corporate investors must clearly understand the implications of this structure.
Purchasing SpaceX shares means participating in economic returns rather than participating in management, and investors must consider prior to making an investment decision that there are virtually no means for shareholders to respond to the personal judgment of the founder or changes in external circumstances.
According to Bloomberg and CNBC, the lead underwriters for the listing are Bank of America, Goldman Sachs, JPMorgan Chase, and Morgan Stanley, and plans are underway to allocate up to 30% of the IPO volume to retail investors, which is a higher level than the typical retail allocation ratio for large IPOs.
Prior to Public S-1 Filing, Financial Figures Remain an Unconfirmed Area
Financial figures currently circulating in domestic and foreign media, such as SpaceX's sales, profits, and subscriber numbers, are all reports based on anonymous sources or analyst estimates.
The figures vary considerably depending on the source, and the fact that SpaceX, as a private company, has not disclosed its financial statements prior to the IPO is the fundamental cause of this uncertainty.
According to analysis by the KBR Business Research Institute, official figures with legal validity can be confirmed for the first time when the public S-1 is filed on EDGAR. It is appropriate to judge reliable financial information that Korean corporate readers can utilize for decision-making only after that point.
Korea's Direct Participation Barriers and Practical Alternatives
Whether Korean retail investors can directly participate in the SpaceX IPO public offering remains undecided at this time.
According to analysis by the KBR Business Research Institute, the structural cause of this issue lies in the mismatch between Korean and U.S. IPO systems. In U.S. IPOs, underwriters distribute shares centered around institutional investors and there is no legal obligation for retail investor allocation ratios, whereas in Korea, to allocate public offering shares to individual investors, a separate registration application must be submitted to financial authorities and public offering subscription procedures must be undertaken, with this process alone taking a certain statutory period. The core issue is the narrow time gap between the June listing schedule and these procedures.
Mirae Asset Securities has pursued a structure to receive an allocation of volume in the SpaceX IPO and provide it to domestic investors in the form of a public subscription, but Mirae Asset stated, "Since this is the first attempt at a simultaneous public offering in the U.S. and Korea, there are challenges," and "Once the allocation scale is finalized, full-scale discussions will begin." In preparation for cases where direct public offering participation is difficult, domestic asset management companies have already taken action.
Mirae Asset Global Investments announced the launch of the TIGER US Space Tech ETF, and Korea Investment Management announced the launch of the ACE US Space Tech Active ETF, each planning to incorporate SpaceX immediately after its listing. According to analysis by the KBR Business Research Institute, regardless of whether one directly participates in the public offering, indirect exposure through ETFs is the most realistic approach for Korean investors at present.
