Reports came out last week that SpaceX might file for an IPO soon. The valuation is estimated around $1.75 trillion. They have basically taken over US space flight. Their Falcon 9 rocket has a 99.8% success rate over 621 launches, and its reusability keeps costs down. They are NASA's main partner for the ISS and are competing with Blue Origin for the Artemis lunar lander contract. SpaceX has a much stronger track record since Blue Origin has very limited orbital launch experience. If they list, they would be the biggest pure-play space company on the market. Legacy players like Boeing and Lockheed are more focused on general aerospace and defense. SpaceX also brings Starlink and potential defense contracts to the table.
