SpaceX's Grain spectrum purchase, put at nearly $8 billion by a source, is under a tenth of the more than $80 billion TD Cowen says a mobile network would cost. The build would draw on the same cash as Starship, AI infrastructure and the Terafab chip factory.
Reality
SpaceX agreed on Thursday to buy Grain Management's nationwide 800 MHz spectrum portfolio for Starlink Mobile, pending approval from the FCC. AT&T, Verizon and T-Mobile shares fell after hours on fears that a satellite rival that can reach phones indoors will start a price war.

AT&T and T-Mobile fell about 9% and Verizon 6% on Friday morning after SpaceX said it was buying low-band spectrum from Grain Management. That spectrum alone cannot carry a nationwide network, so the carriers' first bill may come at spectrum auctions, where Evercore expects SpaceX to push up prices.
Reality
SpaceX's reported $8 billion purchase of 14 MHz brings Starlink Mobile to roughly 80 MHz, T-Mobile CTO John Saw wrote, against his carrier's nearly 400 MHz. His wider argument is that most phone traffic happens indoors, where SpaceX would have to add coverage one building at a time.
