SpaceX Files for Record $1.75 Trillion IPO After Completing xAI Merger
SpaceX filed a confidential S-1 registration statement with the Securities and Exchange Commission in early April 2026. The filing targets a $1.75 trillion valuation, which would make it the largest IPO in history.
The xAI Acquisition
The IPO filing follows SpaceX's completed acquisition of xAI, Elon Musk's AI company, in an all-stock deal. CNBC reported the combined entity is valued at $1.25 trillion, making it the biggest merger of all time. xAI now operates as a wholly owned subsidiary of SpaceX.
Space-Based Data Centers
Musk stated that the merger is about building data centers in space. He argued that current AI advances depend on large ground-based data centers that require massive amounts of power and cooling. Space-based infrastructure could solve both problems by using solar power and the natural cooling of space.
Grok Integration
The combined company plans to embed xAI's Grok models into SpaceX operations to accelerate development of autonomous spacecraft and robotic systems. Reports also indicate that Musk is requiring banks involved in the IPO to purchase Grok subscriptions.
Why It Matters
The merger creates the world's most valuable private company and combines two industries, space and AI, that have largely operated separately. If the IPO goes forward at the target valuation, it would reset expectations for what a technology company can be worth at listing.
