I don’t know; I haven’t investigated. My guess is that the Falcon 9 is the most impressive of all the things Musk has done so far, but cost per kilogram to orbit is a weird metric because of how corrupt and ossified the industry is (other than SpaceX.) When companies like Boeing, ULA, etc. manage to lobby politicians to throw huge wads of cash at them for inferior products, and then SpaceX comes along and undercuts them with a superior product, who knows what the “real” costs-per-kilogram are? Both SpaceX and its competitors are probably charging substantially more than they need to.
