Elon Musk’s SpaceX and xAI are in merger talks ahead of a June 2026 IPO that could raise $50 billion at a $1.5 trillion valuation, Bloomberg and Reuters reported January 29. Corporate filings show two merger entities formed January 21 in Nevada, listing SpaceX CFO Bret Johnsen as an officer. The combined entity would unite SpaceX’s rockets, Starlink’s 6,000 satellites (with plans for 1 million more as orbital data centers), X platform, and Grok AI chatbot—potentially the largest IPO in history.
Space Infrastructure Meets AI: What Musk Is Combining
This isn’t just another tech merger. SpaceX (valued at $800 billion) and xAI (valued at $230 billion) would create the first vertically integrated space-AI infrastructure company. The prize asset: Starlink satellites powering orbital data centers.
SpaceX filed with the FCC on January 8 to launch up to 1 million satellites designed as orbital data centers powered by solar energy. Starlink V3 satellites will deliver 10x capacity (1 terabit per second), edge inferencing modules, GPU housings, and enhanced thermal controls. SpaceX’s pitch: “Orbital data centers are the most efficient way to meet accelerating AI computing demand” since they eliminate cooling costs and use constant solar power.
The problem? Space data centers face unsolved engineering challenges: thermal management (radiating heat in vacuum), radiation hardening (cosmic rays degrade GPUs), and orbital debris mitigation (1 million satellites mean collision risk). Furthermore, SpaceX’s FCC filing is 167 times larger than the current Starlink constellation. No orbital data center has operated at scale. This could be visionary infrastructure or financial engineering to inflate the IPO.

Pentagon Bets on Grok: Defense Contracts Drive Value
The merger’s strategic kicker: Pentagon contracts. U.S. Defense Secretary announced January 12 that the Department of Defense will integrate Grok into classified and unclassified military networks via the GenAI.mil platform. As a result, xAI joins Google Gemini, OpenAI, and Anthropic in a $200 million Pentagon AI contract pool.
SpaceX already dominates military satellite launches—$714 million in fiscal 2026 contracts, $6 billion through the 2030s, and the majority of U.S. military satellites. Combining launch infrastructure with AI creates an integrated defense offering no competitor can match. One company controls space access and military AI capabilities.
The controversy? Defense One reports Grok integration bypassed typical ethical oversight that delayed other AI contracts. The Pentagon’s new “AI acceleration strategy” prioritizes deployment speed over safety reviews. Consequently, concentrating military AI in Musk’s empire raises national security questions about single points of failure.
The $2.35 Trillion AI IPO Battle
SpaceX/xAI isn’t going public alone. OpenAI (valued at $500 billion, targeting Q4 2026) and Anthropic (valued at $350 billion, targeting 2026) are racing to market, totaling $2.35 trillion in AI IPO valuations in one year. Public markets have never tested investor appetite for this much AI equity at once.
The competitive dynamic: SpaceX pursues vertical integration (infrastructure plus models), OpenAI partners with Microsoft Azure for compute, Anthropic partners with Google Cloud, and Google builds everything in-house plus Project Suncatcher (orbital compute prototype targeting 2027). Moreover, xAI’s revenue growth—$100 million in late 2024 to $3.2 billion annualized in 2026 (32x)—looks impressive until you compare it to Anthropic’s $4 billion annualized revenue or OpenAI’s market dominance.
Here’s the problem: all three companies have reached model convergence. GPT-5, Claude Opus 4.5, and Grok 5 (planned Q1 2026 with 6 trillion parameters) deliver similar reasoning capabilities. Therefore, competition shifts to infrastructure, distribution, and pricing. SpaceX’s satellite network becomes the differentiator—if orbital data centers work.

What Could Go Wrong
Start with regulatory scrutiny. The FTC and DOJ will examine monopoly power across space launch (SpaceX controls 60% of global mass to orbit), satellite communications (Starlink has no serious competitors), AI (xAI vs. OpenAI/Anthropic), and social media (X platform). Recent precedents: FTC blocked Meta-Within, while Microsoft-Activision took 18 months to approve. Expect 12-24 month delays, potential divestitures, or outright rejection.
Then there’s technical risk. Satellite industry analysts ask the right questions: Can orbital data centers prove economically viable versus ground-based? Ground data centers benefit from easy maintenance, component upgrades, and established supply chains. In contrast, orbital compute requires fault tolerance (no on-site repairs), modular GPU swaps via robotic servicing missions, and strict debris avoidance. SpaceX needs to prove this works before the IPO.
Finally, valuation skepticism. $1.5 trillion assumes perfect synergy between rockets, satellites, AI, and social media. However, investors may see conglomerate discount, not premium. Combining disparate businesses rarely creates value beyond financial engineering. The market will decide in June 2026—if regulators allow it.
Key Takeaways
- Merger targets mid-June 2026 IPO at $1.5 trillion valuation, raising $50 billion—potentially the largest IPO in history, surpassing Saudi Aramco’s 2019 flotation
- Combines space launch, satellite network, AI models, and social data under one entity, creating the first vertically integrated space-AI infrastructure company
- Pentagon Grok integration strengthens defense contracting position—SpaceX dominates military satellite launches, xAI joins GenAI.mil platform alongside Google, OpenAI, and Anthropic
- Faces FTC/DOJ antitrust review that could delay or block the merger, with 12-24 month regulatory timeline expected for consolidation of this scale
- Orbital data centers remain unproven at scale—thermal management, radiation hardening, and debris mitigation are unsolved engineering challenges. Watch Starlink V3 launches in first half 2026 for proof of concept
