SpaceX was worth just under $2.8tn after its shares rose by 13% on opening on the Nasdaq index on Tuesday. overtaking Amazon’s $2.66tn to become the world’s fifth most valuable company by market value.
SpaceX floated at $135 a share on Friday and its shares have risen by approximately 60% since. The float made Musk, SpaceX’s founder and chief executive, the world’s first trillionaire. The 54-year-old is now worth $1.27tn, according to Bloomberg.
