SpaceX 800 MHz spectrum deal awaits FCC

Key Takeaways

The agreement	On Thursday, Oct. 8, SpaceX said it agreed to buy Grain Management's nationwide 800 MHz licenses, up to 14 megahertz of paired spectrum. The sale needs FCC approval, and neither company disclosed the price.
The licenses	A July 1 FCC order said the licenses run from 4.85 to 14 megahertz across 3,224 counties, about the whole U.S. population. Grain bought them from T-Mobile and closed on Tuesday, Aug. 11.
The network	SpaceX says the low band would reach phones inside buildings, next to 2 GHz capacity and a later mix of satellites and ground towers. The FCC has not approved the transfer.
The shares	CNBC reported on Friday, Oct. 9, that AT&T, Verizon and T-Mobile shares tumbled and SpaceX stock rose about 2 percent. The same story also described a separate extended-trading move in SpaceX shares.

Space Exploration Technologies Corp. (SpaceX) agreed on Thursday, Oct. 8, to buy Grain Management's nationwide 800 MHz licenses, up to 14 megahertz of paired spectrum, SpaceX said. The SpaceX 800 MHz spectrum deal needs Federal Communications Commission (FCC) approval before Starlink Mobile, a SpaceX subsidiary, can put the airwaves to use.

What the SpaceX 800 MHz spectrum includes

In an update on Thursday, Oct. 8, SpaceX said it had agreed to acquire "a nationwide low-band spectrum license portfolio of up to 14 megahertz of paired spectrum in the 800 MHz band." SpaceX said the low band should reach devices through walls, while its 2 GHz mid-band spectrum supplies U.S. capacity, and that most phones already support 800 MHz.

"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 US," SpaceX said. After FCC approval, SpaceX said, it would combine satellites with a ground network. With the new licenses and its Gen2 constellation, the company said, Starlink Mobile can "become the first network operator to deploy both satellite and terrestrial spectrum."

Direct-to-device service is a satellite link to a phone. SpaceX's Oct. 8 filing says Starlink serves more than 12 million customers in more than 170 countries as of mid-2026, on over 11,000 satellites. CNBC, citing the second-quarter report, said the service was in 205 countries with 12 million subscribers as of June 30, and that connectivity earned $1.66 billion in operating income on $4.29 billion in revenue.

How Grain got the 800 MHz licenses

Grain Management said on Thursday, Oct. 8, from Washington, D.C., that SpaceX will acquire 100 percent of its nationwide 800 MHz portfolio, subject to FCC approval and other closing conditions. David Grain, founder and chief executive, said the agreement "brings that capability to bear at extraordinary scale, with the potential to change where and how Americans connect." Neither company stated a price.

Grain closed its purchase from T-Mobile on Tuesday, Aug. 11, its closing announcement said, describing 800 MHz Band 26 spectrum with about 14 MHz of blended depth nationwide. The FCC's July 1 order described 4.85 to 14 megahertz in 3,224 counties, about 100 percent of the U.S. population. T-Mobile was to receive $2.9 billion in cash plus Grain's 600 MHz licenses in 212 counties, about 15 percent of the population.

What the applicants asked the FCC to approve

Under a purchase and sale agreement dated Thursday, Oct. 8, control would pass from NewLevel IV, L.P., a Grain affiliate, to Starlink Spectrum Holdings, LLC, the public interest statement says. NewLevel owns Prism License Co. 1 LLC and Prism License Co. 2 LLC, the license holders. Starlink Spectrum Holdings is the wholly owned subsidiary the filing calls Starlink Mobile.

The July 1 order lets satellite service meet construction rules, license by license, if complete satellite applications are filed by Friday, Dec. 4. Benchmarks in that order fall on Nov. 30, 2029, Nov. 30, 2031, and Nov. 30, 2036. The Oct. 8 filing also asks the Space Bureau to add the 800 MHz frequencies to a satellite authorization. The FCC has not granted the license transfer.

A 15,000-satellite grant and an Oct. 29 vote

On Tuesday, Oct. 6, the FCC Space Bureau granted a SpaceX direct-to-cell system of 15,000 satellites, CNBC reported from an FCC release on Wednesday, Oct. 7. The FCC said those satellites will use spectrum SpaceX bought from EchoStar. The Oct. 8 filing cites a May 12, 2026 order on that transaction. SpaceX said the new satellites will deliver more than 100 times the bandwidth of today's Starlink Mobile generation.

The FCC said on Wednesday, Oct. 7, that it will vote on Thursday, Oct. 29, to auction 25 megahertz for direct-to-device service and to seek comment on another 482 megahertz for supplemental coverage from space, CNBC reported. That phrase is the FCC's name for satellite fill-in on a carrier's licensed bands. Broadband Breakfast reported the 25 megahertz would come from 1675-1695 MHz and 2020-2025 MHz, for terrestrial 5G, direct-to-device service, or both.

Carrier shares and their satellite venture

CNBC reported on Friday, Oct. 9, that AT&T, Verizon and T-Mobile shares tumbled that day and that SpaceX stock, ticker SPCX, climbed about 2 percent. The same article also said SpaceX shares rose about 2.5 percent in extended trading after a 4 percent regular-session drop. CNBC did not give percentage drops for the three carriers.

Elon Musk, SpaceX's chief executive, posted "Very big deal" on X on Thursday, Oct. 8. The filing calls SpaceX a publicly traded Texas corporation. CNBC said it went public in June and was valued above $2 trillion.

On Thursday, Oct. 1, AT&T, T-Mobile and Verizon said they formed a joint venture to expand coverage in underserved areas and named Paul Roth interim chief executive. The Verizon announcement says existing carrier-satellite agreements stay in place and does not name Starlink as a venture partner. CNBC reported Starlink was absent and that T-Mobile had removed it from T-Satellite promotions.

Tim Farrar of TMF Associates told CNBC the deal "adds fuel to the fire in the battle between SpaceX and the mobile operators," but that the spectrum is "still a very limited amount" and urban indoor coverage would need ground towers. SpaceX has said it plans that ground piece after approval. Any date a customer could subscribe is not in the announcements or the filing.
