About $22 billion worth of SpaceX's government contracts is at risk and multiple U.S. space programs could face dramatic changes in the fallout of Elon Musk and President Donald Trump's explosive feud on Thursday.

Elon Musk's escalating feud with President Trump could have serious financial fallout for the tech billionaire's companies.

Musk probably doesn’t have much to fear. Legally, the Trump administration would likely enmire itself in lengthy legal disputes if it appeared to cancel contracts out of spite. Moreover, as the world’s No. 1 launch provider and maker of low-Earth orbit satellites, SpaceX may have made itself indispensable.
