Lots of multi-billion valuations in there. I know RocketLab has a real product and doing something. Are any of these others? Last I checked Virgin Galactic was still testing and didn't seem to be ready any day now. I don't recognize the others.
I considered buying VACQ this morning but can't imagine RocketLabs new large rocket competing with StarShip.
Scott Manley made a good point. If you want to compete against Starlink with your own mega constellation, you won't want to use SpaceX as your launch provider... But first, you have to outcompete Starlink! Which isn't going to be easy.
