SpaceX (Space Exploration Technologies Corp.) (Private: SPACEX)

SpaceX is the world's most active rocket launch company and the operator of Starlink, a satellite internet constellation with over 6,000 satellites. They've revolutionized space launch economics with reusable rockets and are developing Starship, the largest rocket ever built. The company dominates commercial launch and is NASA's primary crew transport provider.

Launch services revenue from commercial, government, and military customers, plus Starlink subscription revenue from over 3 million subscribers worldwide. Starlink is becoming the larger revenue driver as the constellation scales. Government contracts (NASA, DoD) provide high-value, long-term revenue.

Founded in 2002 by Elon Musk with the goal of making humanity multiplanetary. The first three Falcon 1 launches failed before the fourth succeeded in 2008. The Falcon 9 became the world's most-launched rocket, and the first successful booster landing in 2015 changed the economics of space. Starship's development is the current focus.
