SpaceX's next big move could shake up not just AT&T, Verizon and T-Mobile, but even Apple and Samsung

Wall Street is starting to realize just how massive Elon Musk's ambitions for Starlink Mobile have become

SpaceX just announced an agreement to acquire nationwide 800 MHz spectrum, bringing it closer to building a mobile network that combines satellites in space with traditional cellular infrastructure on the ground

And now analysts are looking at an even bigger possibility

Gene Munster believes SpaceX could eventually develop its own Starlink smartphone, despite Elon previously saying he doesn't want to make one

Think about what that would mean

SpaceX would control the satellites, spectrum, mobile network and potentially even the smartphone itself

A fully integrated system could offer unique connectivity features, eliminate coverage gaps and potentially deliver cheaper mobile service

AT&T, Verizon and T-Mobile would face a serious new competitor, while Apple and Samsung could find themselves competing with SpaceX in the smartphone market

And the wild part is that SpaceX doesn't even need to build its own phone to start disrupting the telecom industry

Elon is building an entirely new kind of mobile network, and the implications are really enormous
