SpaceX buys nationwide 800 MHz spectrum for terrestrial network

SpaceX agreed on October 8, 2026 to buy a nationwide portfolio of low‑band spectrum from Grain Management for use across the United States. SpaceX’s purchases from EchoStar total about $19.6 billion for two spectrum deals, granting it exclusive S‑band privileges in the United States and worldwide Mobile Satellite Service licenses. Earlier this week the FCC approved SpaceX’s plan to deploy 15,000 second‑generation Starlink satellites.

SpaceX stated that obtaining the nationwide 800 MHz spectrum will allow Starlink Mobile to function as a full United States mobile carrier instead of merely a satellite supplement to another network. SpaceX has targeted 2027 for the deployment of its next‑generation Starlink Mobile satellites and anticipates upgraded service by the end of that year. The Federal Communications Commission’s review of SpaceX’s acquisition of the 800 MHz spectrum from Grain Management will decide when SpaceX can bring the terrestrial component of its Starlink Mobile network into service.

In Aug. 2026 SpaceX President and COO Gwynne Shotwell said she expects Starlink Mobile to win over customers from the major carriers because she believes the service will be better, citing dead‑zone coverage and resilience during disasters. According to LightShed Partners analyst Walter Piecyk, SpaceX paid roughly $8 billion for the 800 MHz spectrum and had earlier spent close to $20 billion on separate EchoStar spectrum acquisitions. Bernstein analyst Douglas Harned estimated that constructing a standalone mobile network for SpaceX would require $50 billion to $130 billion in investment.

JPMorgan analysts estimate that SpaceX will spend a staggering $200 billion or more on capital expenditures in 2027 and 2028. SpaceX reported second‑quarter 2026 capital expenditures of $18.4 billion, greatly exceeding analyst forecasts of around $6 billion. Following the reveal of SpaceX’s low‑band spectrum buy, shares of AT&T, Verizon and T‑Mobile declined in after‑hours trading.

They bought some spectrum and then they went back and bought some more.

SpaceX explained that its 2 GHz band provides high‑capacity throughput, whereas the added 800 MHz layer improves building penetration, so handsets can work inside structures. The firm noted that current handsets mostly support the 800 MHz frequency, eliminating the need for buyers to buy new phones. The 2 GHz band originates from SpaceX’s EchoStar buy last year, which secured exclusive S‑band authority domestically and for worldwide Mobile Satellite Service.

Unlike the satellite‑focused 2 GHz band, the 800 MHz holdings from Grain Management are intended for terrestrial tower transmission. SpaceX claimed that pairing its satellite spectrum with the newly acquired ground‑based 800 MHz band would make Starlink Mobile the first carrier to use both space‑ and earth‑linked frequencies. Rival AST SpaceMobile had been testing satellites on the same 800 MHz bands before SpaceX stepped in. After the Oct. 8 announcement, AT&T, Verizon and T‑Mobile saw their shares drop in after‑hours trading.

AT&T, Verizon and T‑Mobile are also taking action. The trio recently unveiled a joint satellite‑phone initiative that appears aimed at countering SpaceX’s move. This is notable given that Starlink currently enables T‑Mobile’s emergency texting service.

Bernstein analyst Douglas Harned wrote that SpaceX is most likely to end with a partnership for its mobile business, but continues to suggest a terrestrial build out is possible. Bernstein analyst Douglas Harned estimated that a greenfield build for SpaceX would cost between $15 billion and $200 billion, noting that the typical method is to scale up Dish’s approximately $7.4 billion cash capex for 24,000 sites and 268 million people, excluding spectrum costs and interest.

SpaceX stock continues to trade off its post‑IPO lows, with shares stabilizing despite uncertainty about the company’s future spending plans. Shares have rallied from an intraday low of $104.83 on August 3, 2026 up to $142 on August 31, 2026. MoffettNathanson analyst Julie Zhu said the pullback in SpaceX’s shares suggests a dampening of expectations and raised the broader question of what SpaceX actually is. Julie Zhu added that until there is clarity on what SpaceX is and expectations are reset, analysts will remain on the sidelines.
