SpaceX Just Passed Amazon. Now Comes the Hard Part.

Three sessions in, SpaceX is the fifth most valuable listed company on earth, north of 2.6 trillion, ahead of Amazon and briefly ahead of Microsoft intraday. That is an astonishing debut, and it is also where the easy part ends.

What the market is actually paying for

This is not a pure rocket company. The bull case is Starlink, a recurring subscription business with global reach, wrapped together with launch dominance and a long option on everything from defense to lunar logistics. Buyers are paying for the whole bundle and the scarcity of owning it in public form.

The part I keep coming back to

The float is tiny, somewhere around 4%. Price discovery on a sliver of shares is not the same as price discovery on the whole company. When lockups roll off and more supply hits the tape, the valuation gets a real test it has not had yet.

How I would play it

I am not shorting a story stock with momentum like this, that is how you get hurt. But I am also not chasing 50% gains in four days. I would rather wait for the first earnings print and the first wave of unlocks to see what real demand looks like.
