SpaceX agrees to buy Grain's 800 MHz airwaves for Starlink phones

On Thursday 8 October Grain Management agreed to sell SpaceX all of its nationwide 800 MHz licences, up to 14 megahertz of paired low-band airwaves that Grain took over from T-Mobile in August for $2.9 billion in cash and its own 600 MHz licences; the companies gave no price, the Wall Street Journal reported about $8 billion, the sale needs the FCC's approval, and the order that let Grain buy the band asks it to finish its search for a satellite partner and tell the regulator the outcome by Thursday 5 November.

What the companies signed

On Thursday 8 October, at 4:17 p.m. Eastern time, Grain Management, an investment firm that specializes in digital infrastructure, announced in Washington a definitive agreement under which SpaceX will acquire 100 percent of Grain's nationwide 800 MHz spectrum portfolio: licences to transmit on a slice of radio frequencies across the whole country. Grain said the airwaves would support satellite direct-to-device service, phones connecting straight to satellites, 'enabling Starlink Mobile to reach customers from both the ground and space'. The sale is subject to approval by the Federal Communications Commission, the FCC, and to other customary closing conditions. Neither company disclosed a price. ^{[1, 7]}

The portfolio gives SpaceX up to 14 megahertz of paired spectrum in the 800 MHz band, RCR Wireless reported. Grain's founder and chief executive, David Grain, said the agreement carries 'the potential to change where and how Americans connect'. Elon Musk, SpaceX's chief executive, said the deal would enable 'complete phone coverage in America', according to RCR. The FCC's chair, Brendan Carr, said in response that there would be 'more investment, more opportunities for a range of providers', Reuters reported. ^{[1, 7, 10]}

Where the airwaves came from

The licences were T-Mobile's until August. On 30 May 2025 T-Mobile agreed with two Grain affiliates, NEWLEVEL IV, L.P. and NEWLEVEL, LLC, to sell its 800 MHz licences for $2.9 billion in cash plus Grain's 600 MHz licences, which T-Mobile was already using under leases. Its quarterly report for the period to 30 June adds that T-Mobile 'may receive a share of certain future proceeds' from deals in which Grain monetizes the 800 MHz licences, subject to conditions and only after Grain earns a certain return on its invested capital. The report put the licences held for sale at $3.6 billion, at cost, on 30 June. ^[3]

T-Mobile inherited the band with Sprint, and the Department of Justice made it sell the licences as a condition of that merger; the FCC noted the spectrum had been 'underutilized in recent years'. The FCC approved the exchange on 1 July 2026 under strict conditions so Grain would not sit on the spectrum: it cut Grain's proposed buildout deadlines of six and twelve years to three and eight, and it tied clearer satellite rules to a 'transparent competitive solicitation process' for a D2D partner, a satellite operator serving phones directly. Grain announced on 11 August that it had completed the purchase, describing about 14 MHz of 'blended spectrum depth nationwide' and naming utilities, enterprises and D2D satellite services as possible users. ^{[2, 4]}

What the band does for a phone

The FCC's order gives the exact frequencies: 817 to 824 MHz paired with 862 to 869 MHz, one block for phones to send and one for the network to answer. That is seven megahertz in each direction, 14 in all by the desk's arithmetic, which matches the up to 14 MHz of paired spectrum RCR Wireless reported for the deal. Low frequencies like these travel long distances and pass through walls and tree cover, a major hurdle for satellite service, and most existing handsets already support the band, Reuters reported. SpaceX already holds global 2 GHz mid-band spectrum for capacity, the amount of traffic a network can carry. ^{[2, 7, 10]}

SpaceX said in a blog post that the deal would let it combine a future generation of satellites with 'an advanced terrestrial deployment that can seamlessly connect devices everywhere', Broadband Breakfast reported, and in its public interest statement to the FCC it said it would put equipment on towers, among other things. Not every reader of the deal agrees on the engineering: analysts at New Street Research wrote that the 14 megahertz is a fraction of the carriers' low-band holdings and that the airwaves are not compatible with SpaceX's current or planned satellites, so they would need new satellite antennas or ground radios. The FCC had also approved SpaceX's application for 15,000 direct-to-device satellites on Wednesday 7 October, RCR reported. ^{[9, 10]}

The price and the reaction

The companies did not share financial terms; the Wall Street Journal reported, citing sources, that the deal is worth about $8 billion, according to Reuters, and Broadband Breakfast reported that Bloomberg gave the same figure. For scale, SpaceX's earlier spectrum purchase from EchoStar is on file: an agreement of 7 September 2025 for 50 MHz of spectrum around 2 GHz for $17 billion, amended on 5 November 2025 to add up to 15 MHz of AWS spectrum, which raised the total to $19,616,737,853, with up to $11,116,737,853 paid in SpaceX Class A stock. Fifty plus up to 15 is up to 65 megahertz by the desk's arithmetic, the 65 megahertz of 2 GHz spectrum Broadband Breakfast reported SpaceX is acquiring from EchoStar. ^{[5, 6, 8, 9]}

Press reported that shares of T-Mobile US, Verizon and AT&T fell in extended trading on Thursday evening and again in Friday's session, along with telecom shares in Canada and Europe, while the tower owners American Tower, Crown Castle and SBA Communications rose; the desk prints no share figures. Verizon's spokesman Rich Young said that 'if they do not have the network to use it, it doesn't matter. It's just empty airwaves', Reuters reported. Evercore ISI's Kutgun Maral said the carriers' 'defenses against low-band spectrum claims are weakening'. ^{[7, 8]}

What settles it next

The sale itself waits on the FCC's approval, which Grain's release names as a condition, together with other customary closing conditions; no date for that review has been published. The order that let Grain buy the band sets its own clock: by Thursday 5 November 2026 Grain must complete its competitive process for a satellite partner and notify the FCC of the outcome in the agency's public filing system, with a certification from a neutral third-party advisor that it followed its bidding rules. ^{[1, 2]}

If Grain meets those selection terms and complete applications for the satellite service are filed by Friday 4 December 2026, the licences can be built out under satellite performance benchmarks, the first of them due on 30 November 2029; otherwise the ground benchmarks apply, the first of them by 1 July 2029 at 33 percent of the population or 25 percent of the area of each licence. The FCC deferred the waivers that would allow satellite use of this band until those applications arrive, and said the public will be able to comment then. ^[2]

Who it reaches

T-Mobile US is reached twice: it sold these licences to Grain, and its filed report says it may share in certain future proceeds when Grain monetizes them, under terms it does not detail. Verizon and AT&T, with T-Mobile, are the national carriers a Starlink Mobile holding its own low-band airwaves would compete against; the three formed a satellite joint venture in May that some analysts see as a response, Reuters reported. ^{[3, 7]}

AST SpaceMobile, a rival satellite-to-phone operator, was reported by Bloomberg to be interested in the same Grain licences, and the FCC cited its filing as showing that at least one D2D operator may be able to meet the band's satellite terms. The tower owners American Tower, Crown Castle and SBA Communications are reached through SpaceX's stated plan to put equipment on towers; Morgan Stanley called the deal 'incrementally constructive' for them, Reuters reported. EchoStar is reached as the seller of SpaceX's 2 GHz and AWS airwaves, part of which it is paid for in SpaceX stock under its filed agreement. ^{[2, 6, 8, 9]}
