SpaceX agreed to buy airwaves T-Mobile sold. T-Mobile's filings say it may get a share.
Grain Management said on Oct. 8 that SpaceX agreed to buy its nationwide 800 MHz airwaves; the price was not disclosed. Grain says it bought them from T-Mobile in August, after an FCC order approving that sale called them underutilized.

- T-Mobile's sale of these airwaves to Grain came with more than a fixed price. Its filings say it may also get a share of certain proceeds Grain makes later, after Grain earns a certain return.
- Now Grain has agreed to sell them to SpaceX. That purchase could bring T-Mobile such a payment. Whether it does depends on SpaceX's price, Grain's return threshold and other terms, and none is public.
- Shares of T-Mobile, Verizon and AT&T fell about 6% after hours, Reuters reported. A Verizon spokesman said that if SpaceX lacks "the network to use it, it doesn't matter."
- A court judgment tied to T-Mobile's Sprint merger made it offer these licenses for sale. DISH agreed in 2020 to pay about $3.6 billion, then never bought them.
- The SpaceX sale still needs FCC approval. Under the FCC's July order, Grain's satellite-partner process was to finish by Nov. 5 if the order's satellite buildout terms are to apply.
The deal: SpaceX agreed to buy all of Grain Management's nationwide 800 MHz airwaves, Grain said in a release after the market closed on Oct. 8. Grain, an investment firm, said the deal would support satellite service straight to phones and other devices, letting SpaceX's Starlink Mobile reach customers from the ground and from space. The sale needs approval from the Federal Communications Commission.Grain The price was not disclosed, Reuters reported.Reuters Grain bought the airwaves from T-Mobile in August, the release said.Grain
After the news: Shares of T-Mobile, Verizon and AT&T fell around 6% in extended trading, Reuters reported.Reuters Earlier that day, before the news, T-Mobile had closed up 2.2% at $171.31.Chart data
Why it matters: The company whose airwaves these were may be paid again. T-Mobile's annual and quarterly reports say it may receive a share of what Grain makes from the licenses, after Grain earns a certain return on its investment.10-Q10-K Neither filing says how big that share is, where that threshold sits, or what the other terms and conditions are. With SpaceX's price undisclosed too, the public record cannot say whether T-Mobile gets anything.

What T-Mobile's filings say about the sale
T-Mobile signed the deal on May 30, 2025, with two affiliates of Grain. It agreed to sell its 800 MHz licenses for $2.9 billion in cash plus Grain's 600 MHz licenses, which T-Mobile was already using under leases. Then comes the sentence that matters now.10-Q
In addition, we may receive a share of certain future proceeds from transactions entered into by Grain that monetize the 800 MHz spectrum licenses, subject to certain terms and conditions and following a certain return on invested capital for Grain.
On June 30, T-Mobile's books carried the licenses at $3.6 billion, held for sale: listed as assets it expected to sell, at their cost. The FCC approved the sale on July 1, and T-Mobile then targeted a closing in the third quarter. It expected the closing to raise its cash income tax bill by about $850 million, and not to have a material effect on its income statement.10-Q Both filings came before the August closing, which Grain announced; T-Mobile has made no SEC filing on the closing since.Grain

| Buyer or measure | Amount | Note |
|---|---|---|
| DISH, 2020 (agreed, never bought) | $3.6B | About $3.6 billion under DISH's July 1, 2020 agreement, which ended April 1, 2024 |
| Grain, 2025 (cash, plus its 600 MHz licenses) | $2.9B | $2.9 billion in cash plus Grain's 600 MHz licenses and a possible share of later proceeds |
| T-Mobile's books (June 30, 2026, at cost) | $3.6B | $3.6 billion held for sale at cost: $2.9 billion and $690 million, by the kind of payment due |
Grain's $2.9 billion came with its 600 MHz licenses, so the two deal prices are not like for like. Sources: T-Mobile Form 10-K filed Feb. 11, 2026, and Form 10-Q filed July 23, 2026.
Airwaves that sat underused
The Justice Department required T-Mobile to divest these licenses as a condition of approving its merger with Sprint, the FCC's July order says. The order calls them "underutilized in recent years."FCC
DISH Network agreed on July 1, 2020, to buy them for about $3.6 billion. In 2023 it paid T-Mobile a $100 million fee to extend its deadline to April 1, 2024, and then it did not buy them. On Oct. 1, 2024, T-Mobile ended a court-required auction of the licenses without a qualifying bid and was relieved of the obligation to sell, its 10-K says. It agreed to sell to Grain the next May.10-KFCC
The licenses Grain bought cover 3,224 counties and about 100% of the U.S. population, according to the FCC. To qualify for the order's satellite buildout terms, Grain was to run a fair, competitive process for a satellite partner: start by Aug. 7, then finish it and report the outcome to the FCC by Nov. 5.FCC Grain says the SpaceX agreement advances that order's objectives.Grain
What others say
Verizon spokesman Rich Young said there were still hurdles after the purchase, Reuters reported. He said that "if they do not have the network to use it, it doesn't matter. It's just empty airwaves."Reuters
The carriers have a satellite plan of their own. On May 14, T-Mobile said it had agreed in principle with AT&T and Verizon to form a satellite joint venture. It would pool spectrum to help satellite providers reach more customers. T-Mobile's 10-Q says it still needs definitive agreements.10-Q
SpaceX was not the only company reported to be interested. In August, Bloomberg's government-news service reported, citing people familiar with the discussions, that SpaceX and AST SpaceMobile were among them. Its headline said the airwaves were valued at $6 billion.Bloomberg Government
As of the morning of Oct. 9, SpaceX had filed no report with the SEC about the Grain deal, and no filing or release gives its price.SECGrain

How we got these numbers
- Prices are end-of-day closes as traded, not adjusted for dividends. Daily moves are close to close. Every T-Mobile close in the chart's Story range is in its data table. The after-hours moves are as Reuters reported them; KeyVex's prices are end-of-day only, so the chart ends at the Oct. 8 close, before the news. The S&P 500 and Nasdaq 100 lines follow SPY and QQQ, also as traded. The Filings switch shows a selection of the filing markers from KeyVex's T-Mobile page, not every filing, and not only those tied to this story.
- The price chart of the 800 MHz licenses compares an agreed price (DISH), an agreed cash payment that came with other licenses (Grain), and an accounting value (T-Mobile's carrying amount at cost). They measure different things and are shown side by side only because the filings state them.
- "About 100% of the U.S. population" and "3,224 counties" describe the licenses Grain bought from T-Mobile, as the FCC's order states them. The FCC's order puts the amount of spectrum at 4.85 to 14 megahertz, depending on the area.
