SpaceX Plans IPO Filing in 2026 Targeting Up to $75 Billion Raise

SpaceX aims to file its IPO prospectus soon, targeting a June 2026 listing to raise $50-$75 billion following its merger with Elon Musk’s xAI.

Published

on

This article summarizes reporting by Reuters

SpaceX is reportedly preparing to file its initial public offering (IPO) prospectus with U.S. regulators as early as this week or next. According to reporting by Reuters and The Information, the aerospace giant is targeting a public listing that could fundamentally reshape global financial markets. Citing a person with direct knowledge of the plans, the reports indicate that the company is moving swiftly toward a highly anticipated market debut.

The anticipated IPO, projected for June 2026, follows SpaceX’s recent strategic merger with Elon Musk’s artificial intelligence startup, xAI. Industry estimates suggest the company could attempt to raise between $50 billion and $75 billion, potentially making it the largest public offering in history. This massive capital injection is expected to fund a new era of space-based infrastructure and interplanetary exploration.

At AirPro News, we note that this move represents a significant operational shift for the company, transitioning from a pure aerospace manufacturers into a combined space and AI infrastructure conglomerate. The offering is expected to draw unprecedented interest from both institutional and retail investors, marking a watershed moment for the commercial space industry.

Record-Breaking Financial Projections and Retail Allocation

If current projections hold true, SpaceX’s market debut will shatter existing Financial-Results. Advisers predict the capital raise could reach up to $75 billion, which would easily surpass the current $26 billion global record set by Saudi Aramco in 2019. The company is reportedly targeting a public valuation between $1.5 trillion and $1.75 trillion. For context, a recent secondary market insider share sale valued SpaceX at approximately $800 billion, or $421 per share.

Unprecedented Retail Investor Access

In a highly unusual move for an offering of this magnitude, reports indicate that SpaceX may allocate more than 20% of its shares to individual retail investors. While the exact percentage remains unfinalized, this strategy would democratize access to one of the most anticipated tech listings of the decade, allowing the general public to participate directly in the company’s growth.

Post-IPO corporate governance will likely feature a dual-class share structure. According to industry reports, this arrangement would allow company insiders, notably CEO Elon Musk, to retain outsized voting power over corporate decisions, ensuring leadership continuity as the company navigates its public transition.

The xAI Merger and the Convergence of Space and AI

A crucial catalyst for this IPO is SpaceX’s recent corporate transformation. In early February 2026, SpaceX acquired Musk’s AI startup, xAI, in an all-stock reverse triangular merger. The deal valued SpaceX at $1 trillion and xAI at $250 billion, creating a combined entity valued at $1.25 trillion. Notably, xAI also owns the social media platform X (formerly Twitter), bringing a diverse portfolio of technology assets under one umbrella.

The integration, however, has seen significant leadership turnover. Following the merger, nine of the eleven original xAI co-founders departed the company by mid-March 2026. Addressing the exodus, Musk publicly acknowledged the departures.

“[The AI lab is being] rebuilt from the foundations up,” Musk stated regarding the recent xAI leadership changes.

Additionally, corporate ties between Musk’s ventures continue to tighten. On March 11, 2026, the FTC approved Tesla’s move to convert a previous $2 billion investments in xAI into a direct equity stake in SpaceX, representing less than 1% ownership in the aerospace company.

Proposed Use of Proceeds: Orbital Data Centers and Mars

Space-Based AI Infrastructure

A $75 billion capital injection is expected to fund several highly ambitious, capital-intensive projects. A primary driver of the xAI merger is the concept of building solar-powered orbital data centers. This initiative aims to bypass terrestrial constraints regarding the massive electricity and water cooling requirements necessary for modern AI compute clusters.

Scaling Starlink and Starship

Funds will also be directed toward scaling the Starlink internet service, which generated an estimated $10 billion in revenue in 2025, and building out its direct-to-cell satellite constellation. Furthermore, the capital will support the super-heavy reusable Starship rocket, alongside development for “Moonbase Alpha” and future uncrewed and crewed missions to Mars.

The IPO proceeds are expected to fund “insane flight rates” for the Starship program, according to industry research.

Market Sentiment and Expert Opinions

Financial analysts are divided on the massive valuation targets. PitchBook analysts place SpaceX’s fair value between $1.1 trillion and $1.7 trillion, noting that the valuation becomes easier to justify over a five-to-seven-year horizon as Starship commercializes and Starlink scales.

Morningstar analysts have called the $1.5 trillion price tag “expensive and risky, but not irrational,” provided execution timelines are met.

AirPro News analysis

We observe that the xAI merger introduces complex AI-related regulatory risks and integration challenges that prospective investors must weigh carefully. Furthermore, the heavy reliance on Elon Musk introduces significant key person governance risk. The interconnected nature of Musk’s companies, Tesla, X, xAI, and SpaceX, creates a unique but potentially volatile corporate ecosystem that will face intense scrutiny from public market regulators.

Speculation regarding further consolidation is already circulating among market watchers. Following a recent joint venture announcement for a chip factory called “Terafab” in Austin, Texas, Wedbush analyst Dan Ives predicted that Tesla and SpaceX could fully merge by 2027. Conversely, Gary Black of The Future Fund strongly criticized this idea, warning that a merger could erase $750 billion in Tesla’s value due to a “conglomerate discount” where the lowest common market multiple prevails.

This article is based on an official press release from Northrop Grumman and supplementary industry research.

Northrop Grumman is currently preparing for its 24th commercial resupply services (CRS) mission to the International Space Station (ISS), officially designated as NG-24. Targeted for launch in early April 2026, with industry tracking sources pointing to an April 8 to April 9 window, the mission will deliver critical hardware, scientific experiments, and crew provisions to the orbiting laboratory. According to the official mission profile, the spacecraft will carry more than 8,200 pounds of cargo.

The NG-24 mission will utilize a SpaceX Falcon 9 Block 5 rocket, launching from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. This flight marks the second operational use of Northrop Grumman’s upgraded “Cygnus XL” spacecraft variant. In keeping with the company’s long-standing tradition of honoring aerospace pioneers, the NG-24 spacecraft has been named the S.S. Steven R. Nagel.

For the commercial spaceflight sector, this mission represents a vital continuation of NASA’s supply chain. It also highlights a transitional era for Northrop Grumman’s launch vehicle fleet and showcases the growing involvement of university-level engineering in deep space research.

The S.S. Steven R. Nagel and Scientific Payload

Honoring an Aerospace Pioneer

Northrop Grumman traditionally names each of its Cygnus spacecraft after an individual who has made significant contributions to human spaceflight. For the NG-24 mission, the company has chosen to honor the late Colonel Steven R. Nagel. According to biographical data released alongside the mission profile, Nagel was a distinguished U.S. Air Force pilot who joined NASA as an astronaut in 1979.

Nagel’s legacy includes flying on four Space Shuttle missions: STS-51G, STS-61A, STS-37, and STS-55. He is perhaps best known for commanding STS-37, the mission responsible for successfully deploying the Compton Gamma Ray Observatory, a payload that fundamentally expanded humanity’s understanding of the cosmos. Over the course of his career, Nagel logged 723 hours in space and became highly regarded for his dedication to mentoring the next generation of aerospace engineers and astronauts.

Scientific Cargo: LeopardSat-1

While NASA typically releases a comprehensive payload manifest closer to the launch date, early mission documentation confirms that the Cygnus XL will carry a variety of cutting-edge scientific investigations. One of the highlighted payloads is LeopardSat-1, a cube satellite (CubeSat) developed by “CubeCats,” a student organization based at the University of Cincinnati.

Industry research notes that this 10-centimeter by 10-centimeter by 10-centimeter satellite marks the university’s first-ever space mission and the first student-led satellite from the state of Ohio. LeopardSat-1 is designed to test the effectiveness of a thin, lightweight carbon sheeting in blocking cosmic radiation. If the experiment yields positive results, this innovative material could eventually replace heavy traditional radiation shielding, such as water and lead, protecting astronauts on long-duration deep space missions to destinations like Mars.

Industry Context and the Shift to SpaceX

Bridging the Launch Gap

The NG-24 mission occurs during a significant transitional period for Northrop Grumman’s launch operations. Historically, Cygnus spacecraft were launched aboard Northrop Grumman’s own Antares rockets from Wallops Island, Virginia. However, NG-24 will be the fourth Cygnus mission to launch atop a competitor’s rocket, the SpaceX Falcon 9.

This shift was necessitated by the retirement of the Antares 230+ rocket in August 2023. The Antares 230+ relied on Russian-built RD-181 engines. Following geopolitical tensions and the invasion of Ukraine, the U.S. Congress mandated an end to the aerospace sector’s reliance on Russian rocket engines. To bridge the resulting launch gap, Northrop Grumman contracted SpaceX for a series of missions while simultaneously developing its next-generation medium-class launch vehicle, the Antares 330, in partnership with Firefly Aerospace. The Antares 330 is projected to come online later in 2026.

The Cygnus XL Upgrade

The spacecraft itself features significant technological advancements. NG-24 is only the second flight of the “Cygnus XL” variant, following its debut on the NG-23 mission in late 2025. According to company specifications, the XL version features an extended pressurized cargo module, which provides approximately 33 percent greater volume for cargo compared to its predecessor.

“Since its first operational mission in 2013, Northrop Grumman has delivered more than 158,000 pounds of essential supplies, experiments, and equipment to the ISS under NASA’s Commercial Resupply Services contracts,” according to historical mission data.

AirPro News analysis

The NG-24 mission perfectly illustrates the current dynamic of “coopetition” within the U.S. commercial space sector. Northrop Grumman’s decision to utilize a SpaceX Falcon 9 rocket to fulfill its NASA CRS obligations demonstrates a mature, pragmatic industry where rivals collaborate to ensure uninterrupted service to the ISS. Furthermore, the forced retirement of the Antares 230+ and the subsequent development of the Antares 330 underscore a broader, industry-wide push to secure domestic supply chains and eliminate reliance on foreign aerospace hardware. As the Cygnus XL proves its expanded capabilities, Northrop Grumman is well-positioned to maintain its critical role in orbital logistics once its proprietary launch vehicles return to the pad.
