AT&T just dropped $23 billion in cash to buy wireless spectrum from EchoStar, sending EchoStar shares rocketing 75% higher in the biggest telecom deal of 2025. The acquisition resolves a bitter FCC investigation sparked by complaints from Elon Musk's SpaceX that EchoStar was hoarding valuable mid-band spectrum instead of using it.
EchoStar shareholders are having the kind of Tuesday that makes careers. The satellite communications company's stock exploded 75% higher after AT&T announced it would acquire EchoStar's wireless spectrum licenses for $23 billion in an all-cash transaction that instantly transforms both companies' competitive positions.
The deal delivers AT&T approximately 50 megahertz of precious mid-band and low-band spectrum covering more than 400 markets across the United States. For perspective, that's the kind of nationwide coverage that typically takes years and billions more to assemble piecemeal through FCC auctions. AT&T CEO John Stankey called it "a win all the way around" during a CNBC interview, emphasizing how the expanded spectrum will accelerate the carrier's 5G buildout timeline.
But this isn't just about network capacity. The transaction resolves what had become an increasingly heated regulatory standoff between EchoStar and Elon Musk's SpaceX over spectrum utilization. According to FCC documents, SpaceX had formally complained that EchoStar was leaving "valuable mid-band spectrum chronically underused" while blocking "new satellite entrants" from accessing those frequencies for Starlink operations.
The dispute escalated in May when FCC Chairman Brendan Carr sent a pointed letter to EchoStar cofounder Charlie Ergen, announcing the agency would investigate whether the company was meeting federal requirements to actually build and operate a 5G network with its spectrum holdings. That investigation threat has now evaporated with AT&T taking ownership.
"EchoStar and Boost Mobile have met all of the FCC's network buildout milestones," Ergen said in Tuesday's announcement. "However, this spectrum sale to AT&T and hybrid MNO agreement are critical steps toward resolving the FCC's spectrum utilization concerns."
That hybrid mobile network operator agreement represents the deal's most intriguing strategic element. Rather than simply selling spectrum and walking away, EchoStar will continue operating wireless services under its Boost Mobile brand using AT&T's expanded network infrastructure. This creates a new competitive dynamic where EchoStar maintains customer relationships while AT&T gains both spectrum depth and a wholesale revenue stream.
