SpaceX Wants to Buy All of Grain's Phone Airwaves — Deal Isn't Done Yet
SpaceX has agreed to buy 100% of Grain Management's nationwide 800 MHz airwaves in a deal announced October 8, 2026. Spectrum is the invisible lanes that carry phone calls and data, and low-band lanes travel far and pass through buildings well.
The sale still needs approval from the Federal Communications Commission, the U.S. agency that oversees phone networks, plus other normal closing steps, according to the announcement reported by Reuters and detailed in Grain's disclosure carried by Yahoo Finance. Milbank advised Grain on the sale.
These licenses came from T-Mobile US Inc. They became available after Grain finished an airwave swap with T-Mobile, as reported by Bloomberg. Grain had made an exclusive deal to get that 800 MHz holding from T-Mobile on March 20, 2025, with a plan to support communications for utilities like power and water, according to Grain Management.
Grain then asked for early offers by the first week of September for those licenses. On August 20, 2026, Bloomberg reported that SpaceX and AST wanted to buy airwaves valued at $6 billion. That $6 billion number described the sale process. It was not listed as the deal price in the October 8 announcements.
Separately, SpaceX said in a June 11, 2026 IPO roadshow presentation that it had deals to buy 65 MHz of U.S. airwaves, with closing expected in November 2027, according to the roadshow document. MHz measures how much airwave space is involved. The roadshow did not name the seller for that 65 MHz. The October 8 announcements gave no closing date for the Grain holding beyond FCC approval and normal conditions.
Verizon shares fell nearly 7% in trading after the market closed on October 8. AT&T shares fell nearly 7% the same way.
The broader context here matters for ordinary savers. August reporting named two interested buyers, SpaceX and AST, with a $6 billion marker. The October deal names one buyer, SpaceX, for 100%, with no confirmed price and no mention of AST. Treat October as the official record and $6 billion as background only.
Timing also deserves attention. The November 2027 date from June came before Grain's September deadline and the October deal. Whether that date covers the Grain airwaves, a different set, or a step-by-step close will decide when the airwaves can be used and when money moves. FCC review controls the timing, with close checks on competition and on buildout and interference rules.
The use-case shift is also material for phone bills. Grain bought to help utilities. It is selling to an operator with a space-based system. Moving 800 MHz from utility use to a nationwide mobile layer changes the rulebook, the technical coordination work, and the building costs tied to the licenses. That change helps explain the fast drop in Verizon and AT&T shares.
What to watch now is narrow. Look for the FCC filing terms, any stated price or loan plan, the exact MHz amount compared with the 65 MHz roadshow number, and whether AST or another party keeps any piece. Until those filings appear, the fact is simple. Terms are agreed. Ownership has not moved.
