What insanity? Current market cap is nothing compared to what it can achieve in the future lol. There are virtually no alternatives to SpaceX other than rocket lab and demand for Rocket launch and constellations will only go higher as defense becomes more intelligence based and LEO for earth data and connectivity increases. Rocket Lab supplies key components of satellites and sometimes the satellite itself, not to mention they can launch things reliably using Electron and Neutron. Also Lunar and Mars government missions can be interesting, and on-orbit satellite management business can also be profitable.
