SpaceX is preparing for what could be the largest initial public offering in history, targeting a $75 billion raise at a valuation of $1.75 to $2 trillion. But beneath the record-breaking numbers lies a high-stakes gamble: the company is banking on futuristic technologies like orbital data centers and custom semiconductor manufacturing to justify a valuation that independent analysts say may be inflated by as much as 60 percent.

The IPO, scheduled for June 12 on Nasdaq under the ticker SPCX, comes as SpaceX faces mounting pressure to consolidate its sprawling empire. In February 2026, SpaceX officially merged with xAI, folding the social network X and the Grok artificial intelligence model into the SpaceX corporate structure. This merger valued xAI at $250 billion, but because Elon Musk controlled all the entities involved, the price was determined through internal deliberations rather than open market competition, raising concerns among investors about what analysts call "related-party transactions".

Why Is SpaceX Raising $75 Billion Right Now?

The IPO proceeds are not primarily earmarked for building more rockets or expanding launch services. Instead, SpaceX faces a mandatory "deleveraging" requirement: the company must use IPO proceeds to repay a $20 billion bridge loan within six months. This loan, secured in March 2026 and led by Goldman Sachs, was used to retire $17.5 billion of high-interest debt sitting on the balance sheets of X and xAI.

This creates an unusual situation for an IPO. Normally, capital raised through a public offering funds growth and research and development. Here, a significant portion of the $75 billion will go toward debt repayment rather than productive investments. The company is also seeking capital to fund its Orbital Data Centre initiative and terrestrial expansion of its artificial intelligence unit.

Investors are scrutinizing what analysts at Morningstar call the "Frankenco" structure of the company, where profits from Starlink, SpaceX's space-based internet service, are being used to offset xAI's heavy losses. In 2025 alone, xAI burned nearly $6.4 billion.

What Are SpaceX's Biggest Bets Beyond Rockets?

To justify a $2 trillion valuation, SpaceX needs a market opportunity far larger than traditional launch services. The company is proposing three interconnected initiatives:

• Terafab Semiconductor Factory: SpaceX plans to build a custom GPU manufacturing facility in Grimes County, Texas, at a cost between $55 billion and $119 billion. The goal is to manufacture 1 terawatt of internal computing capacity per year in the form of custom graphics processing units for xAI models and SpaceX satellites.
• Orbital Data Centre Constellation: According to SpaceX's filing with the U.S. Federal Communications Commission, the company plans to deploy 1 million satellites equipped with computing accelerators. The pitch is that AI models running in orbit will harvest 24/7 solar energy and bypass terrestrial land-use regulations.
• Google Partnership Revenue: SpaceX signed a $30 billion agreement with Google through 2029, under which Google will pay approximately $920 million monthly before the IPO to access SpaceX's AI chip clusters as backup capacity for Google's Gemini AI models.

These initiatives represent SpaceX's attempt to claim a portion of the global AI cloud computing market, a far larger addressable market than launch services alone. However, independent experts have raised serious questions about the feasibility of these plans.

What Engineering Challenges Could Derail the Orbital Data Center Plan?

The most significant hurdle facing SpaceX's orbital AI ambitions is heat dissipation. High-performance computing generates enormous amounts of waste heat, and removing that heat in the vacuum of space is exponentially harder than on Earth. On the ground, engineers rely on convection, the natural movement of air from warmer to cooler areas. In space, there is no air, so convection is impossible.

The only viable option is radiation cooling, but physics imposes strict limits. According to the Stefan-Boltzmann law, a satellite attempting to shed 1 megawatt of waste heat at 20 degrees Celsius would need approximately 1,200 square meters of radiator area, larger than the wingspan of a Boeing 747. Engineering skeptics have estimated that the mass of radiators required to cool a gigawatt-scale computational facility in orbit would make the satellites too heavy to be cost-effective, even with Starship's reduced launch costs.

Additionally, high-performance AI chips like NVIDIA's H100 processors or SpaceX's custom silicon are extremely sensitive to single-event upsets from cosmic rays. When a charged particle strikes a sensitive part of a microelectronic device, it can change the device's state and cause errors. To protect against this, chips must be "hardened" to radiation, a process that reduces their performance by orders of magnitude. An alternative approach of launching consumer-grade chips and replacing them every two to three years would heighten space debris risk and inflate costs beyond profitability.

How to Evaluate SpaceX's IPO Risk Factors?

• Valuation Concerns: Morningstar analysts have warned of a valuation bubble, pegging SpaceX's fair value at just $780 billion, less than half of the company's $1.75 to $2 trillion target. The S&P 500, considered the gold standard for stability and retirement funds, has refused to waive its strict inclusion rules for SpaceX.
• Debt Shifting Risk: By using IPO proceeds to pay off the bridge loan, Musk is effectively shifting debt from a private, struggling entity to a public and successful one. If the $1.75 trillion valuation is indeed a bubble, new investors will essentially provide exit liquidity for the banks that originated the bridge loan.
• Regulatory Headwinds: Starlink, SpaceX's existing revenue engine, is facing regulatory pressure in Europe. In May 2026, the European Commission proposed new regulations to limit third-country satellite operators, including U.S. operators, to only one-third of Europe's bandwidth. This significantly shrinks Starlink's addressable market in a high-wealth region.
• Phantom Product Risk: Even if SpaceX captures 100 percent of the global launch market, that represents only a roughly $20 billion per year industry. If the orbital data center is physically impossible or economically unviable due to cooling constraints, the $2 trillion valuation will effectively be based on a phantom product.

Musk is betting that he can build Terafab and the orbital data center fast enough for the revenue they generate to dwarf the $20 billion debt he transferred into SpaceX. By announcing a capital-intensive project in the form of Terafab, SpaceX is attempting to force the market to keep funding it. While this structure has many characteristics of a Ponzi scheme, analysts note it is technically a gamble rather than fraud.

The SpaceX IPO represents a critical moment for the company and for Musk's broader empire. Success would validate his vision of AI-powered orbital infrastructure and custom semiconductor manufacturing. Failure could expose the financial fragility underlying the merger of SpaceX, xAI, and X, and raise questions about how long Starlink's profits can sustain losses across the broader corporate structure.
