Elon Musk’s SpaceX is seeking a $1.75 trillion valuation in its forthcoming initial public offering. How far into the ​stratosphere is that?

Going by common Wall Street metrics, the answer is, way out there. SpaceX would immediately become the sixth most-valuable publicly listed U.S. firm, worth more than the likes ‌of Meta Platforms, which has been publicly listed for more than a decade, and Berkshire Hathaway, a company older than SpaceX founder Elon ​Musk.
