RE:SpaceXYou can add Northrop Grumman to this list however, like United Launch Alliance (ULA), it is highly military/defense related. That vetting process is long. I don't see them taking on RHC at this stage.
SpaceX is clearly the front runner. This is positive because SpaceX is more popular with the retail investor segment who will purchase RHC at these levels. Especially those who think Elon Musk walks on water. Once the production starts up and RHC is de-risked further, then you'll start to see the larger institutions come in.
