SpaceX filed confidentially with the SEC on April 1, targeting a June listing at a $1.75 trillion valuation and up to $75 billion in proceeds, which would make it the largest IPO in history. The framing in most coverage treats this as a space story. It's not, really. Following February's merger, SpaceX now owns xAI (Grok) and X, making it a vertically integrated space-AI conglomerate going public on an AI-forward roadshow narrative. The thesis isn't that capital rotates away from AI infrastructure names. SpaceX is positioning as one of them.
The structure of this deal is a cross-subsidy argument dressed as a valuation argument. The Starlink side cleared roughly $8 billion in profit last year on $15–16 billion in revenue. xAI is burning approximately $1 billion per month. At $16 billion in 2025 revenue, the $1.75 trillion target implies over 100x revenue. The roadshow pitch is essentially: Starlink's recurring satellite cash flow can carry xAI's model ambitions long enough for orbital data centers to become economically real. That's a specific and unproven bet. I don't think it's obviously wrong. I do think it's a much shakier foundation than the headline number implies.
One technical detail that doesn't get enough attention: Nasdaq recently changed rules that could allow SpaceX to join the Nasdaq 100 within 15 days of listing, triggering forced buying from index-tracking funds. That's a meaningful first-day bid with nothing to do with fundamentals. It inflates the opening dynamics and probably the valuation anchor for a while after.
