Elon Musk's SpaceX has confidentially filed paperwork with the SEC for an initial public offering.

Reports indicate the company is targeting a valuation exceeding $1.75 trillion following its merger with Musk's artificial intelligence startup xAI. The IPO aims to raise up to $75 billion, potentially becoming the largest public offering in history.

The filing is expected to launch in June. The funds would support an "insane flight rate" for SpaceX's Starship rocket, AI data centers in space, and lunar base ambitions.

Musk's long-term vision centers on Starship for missions to the Moon and Mars, though the program has faced setbacks including explosions.
