Elon Musk’s SpaceX buys the airwaves it needs to take on Verizon, AT&T and T-Mobile

World's richest man, Elon Musk’s SpaceX is buying the one thing it lacked to compete head-on with America’s mobile networks: licensed spectrum on the ground. The company said on Thursday it will acquire up to 14 megahertz in the 800MHz band from Grain Management, an infrastructure investor, subject to regulatory approval.

“This prime low-band spectrum addresses one of the key remaining technical gaps that will pave the way for Starlink Mobile to become a major mobile carrier in the U.S.,” SpaceX said. Musk called it “a very big deal.”

The market treated it as one. Verizon fell nearly 6% in overnight trading, and AT&T and T-Mobile US each moved more than 6%, Investor’s Business Daily reported, with Forbes describing all three as slumping. AST SpaceMobile, the satellite-to-phone startup that depends on partnerships with those carriers, fell nearly 4%. SpaceX shares, which had dropped 4.2% during Thursday’s session on reports of a $40 billion debt plan for Nvidia chips, rose more than 2% after hours. The purchase price was not disclosed.

Low-band spectrum is the scarce asset in American wireless. Signals in the 800MHz range travel far and penetrate buildings, which is why the incumbents built their networks on it and why there is almost none left to buy. Starlink’s direct-to-cell service has so far run on T-Mobile’s spectrum under a partnership; owning its own band would let SpaceX offer service without a carrier in the middle, combining terrestrial-grade coverage with satellites overhead where no tower reaches.

The satellites are coming too. The Federal Communications Commission recently approved an additional 15,000 next-generation Starlink satellites for the Starlink Mobile constellation, on top of the roughly 11,000 already in orbit, and Starship delivered its first 26 operational V3 satellites to orbit on Sept. 28. SpaceX has said V3 carries 10 times the downlink capacity of the current generation.

The move extends a pattern. SpaceX listed in June at about $2 trillion on the premise that Starlink becomes global infrastructure; Ron Baron’s $1 trillion-a-year revenue forecast assumes it displaces a large share of the telecoms industry rather than supplementing it. Musk has spent the past two weeks fighting for Starlink’s entry into India, accusing Mukesh Ambani and Sunil Mittal’s companies of blocking him, and his company has been kept out of South Africa by ownership rules. The U.S. spectrum purchase is the opposite case: a market where Starlink is already licensed and is now buying its way from partner to rival.

For Verizon, AT&T and T-Mobile, the arithmetic is uncomfortable. They have spent more than $200 billion on spectrum over two decades to keep each other out; the newcomer has rockets, 11,000 satellites, a $40 billion credit line in the works and a founder who treats their business as a subset of his. Thursday’s 6% was the first time the market priced that.
