SpaceX's IPO filing is not just big.

According to Aurelion Research, it is bizarre enough to belong in its own category.

Aurelion's section title, from a note published this week, says it plainly: "SpaceX (SPCX): The Craziest IPO Ever Filed." Then comes the line that explains why this is not just ordinary market hyperbole: "The S-1 IPO filing reads like a sci-fi novel." In most IPOs, investors argue about revenue growth, margins, customer concentration, valuation multiples, and governance.

In SpaceX's case, they still have to do all that — but they also have to think about orbital data centers, AI infrastructure, Elon Musk's voting control and, yes, a permanent Mars colony with at least one million inhabitants.

That is what the headline means.
