SpaceX Agrees to Buy Grain's Nationwide 800 MHz Spectrum — No Price Yet
SpaceX has agreed to buy 100% of Grain Management's nationwide 800 MHz spectrum portfolio under a definitive agreement announced October 8, 2026.
The sale still needs approval from the Federal Communications Commission, the U.S. telecom regulator, plus other standard closing conditions, according to the announcement reported by Reuters and detailed in Grain Management's disclosure carried by Yahoo Finance. Milbank advised Grain on the sale. The deal covers a nationwide low-band footprint, airwaves prized because they travel far and pass through buildings.
Those licenses trace back to T-Mobile US Inc. They became available after Grain completed a spectrum swap with T-Mobile, as reported by Bloomberg. Grain had entered an exclusive arrangement to acquire that 800 MHz portfolio from T-Mobile under a March 20, 2025 agreement built around supporting critical utility communications, according to Grain Management.
Grain then ran a sale process and sought preliminary offers by the first week of September for the licenses it had acquired from T-Mobile. On August 20, 2026, Bloomberg reported that SpaceX and AST were seeking to buy spectrum valued at $6 billion. That valuation described the sale process. It was not restated as deal consideration in the October 8 disclosures.
Separately, SpaceX said in its June 11, 2026 IPO roadshow presentation that it had entered agreements to acquire 65 MHz of U.S. spectrum, with closing expected in November 2027, according to the roadshow document. MHz measures how much spectrum capacity is involved. The roadshow did not identify the counterparty for that 65 MHz in the verified disclosure. No closing date for the Grain portfolio was stated in the October 8 announcements beyond the FCC and standard-conditions qualifier.
Verizon shares fell nearly 7% in after-hours trading after the October 8 announcement. That is trading after the regular market closes. AT&T shares fell nearly 7% on the same basis.
The broader context here is process versus outcome, and savers should not confuse the two. August reporting described two seekers, SpaceX and AST, and a $6 billion marker. The October outcome names one buyer, SpaceX, for 100%, with no confirmed price and no mention of AST. Use October terms as authoritative and treat $6 billion as background on how the asset was shopped, not as payment.
Timing also deserves attention for tracking cash and coverage. SpaceX listed a November 2027 expected close for a 65 MHz U.S. purchase in a June roadshow, before Grain's September bid deadline and the October agreement. Whether that line maps to the Grain portfolio, a separate assembly, or a staged close will decide when spectrum becomes usable and when cash moves. FCC review is the binding constraint, with close scrutiny of competition and of buildout and interference conditions.
The use-case shift is also material for bills and investor returns. Grain bought the position to support utility communications. It is selling to an operator whose disclosed spectrum activity sits alongside a space-based architecture. Moving 800 MHz from utility support to a nationwide low-band mobile layer changes the regulatory story, the interference work, and the capital spending tied to the licenses. That shift helps explain the share move and changes capacity assumptions for incumbents.
What to watch now is narrow. Look for FCC filing terms, any disclosed price or financing structure, the MHz amount compared with the 65 MHz roadshow figure, and whether AST or another party keeps any residual interest. Until those filings appear, the verified position is simple. Terms are agreed. Ownership has not transferred.
