SpaceX Acquires Spectrum from Grain Management and Plans Hybrid Mobile Network from Satellites and Ground Stations

On October 9, 2026, SpaceX announced the acquisition of a nationwide spectrum portfolio from Grain Management LLC, an investment company specialising in digital infrastructure. The transaction includes up to 14 megahertz of paired spectrum in the 800-MHz band. The purchase price was not disclosed, and the deal is subject to approval by the US telecommunications regulator, the FCC.

SpaceX Chief Elon Musk described the acquisition as "the final critical piece of the spectrum puzzle SpaceX needs to provide complete mobile coverage in America". Following FCC approval, the company plans to connect its Starlink satellite constellation with a terrestrial network. The low-frequency spectrum will enable radio signals to be transmitted through walls and buildings to customer devices, thereby bridging coverage gaps.

Hybrid Architecture of Satellite and Mobile Tower

SpaceX is pursuing a hybrid strategy: the company intends to integrate the acquired spectrum into its next-generation satellite system while simultaneously installing ground-based radio equipment and antennas on towers and rooftops. Low-frequency spectrum is particularly suitable for large-scale mobile coverage because its signals bridge longer distances and penetrate buildings better than higher-frequency radio waves. Mid- and high-frequency spectrum, by contrast, carries more data at higher speeds but covers a smaller area.

Already in August 2026, SpaceX COO Gwynne Shotwell announced during the quarterly conference call that the company would build a terrestrial mobile network and compete directly with Verizon, AT&T and T-Mobile for customers. Shotwell stated: "I expect we can win some of their customers because I believe our service will be better." The company also plans to launch second-generation Starlink Mobile satellites in 2027.

Telecom Company Market Values Plummet

The announcement triggered a massive sell-off in the US telecommunications sector on October 9, 2026. T-Mobile shares lost 13 percent, AT&T shares fell 8 to 9 percent, and Verizon shares declined 7 to 8 percent. SpaceX shares, meanwhile, rose 1 to 4 percent. The announcement raised concerns that Starlink Mobile could disrupt the mobile market. Investors reassessed the competitive threat posed by Starlink Mobile, prompting a sell-off across the entire US telecom sector.

On October 12, T-Mobile rebounded 3 percent following the record plunge. Some analysts questioned whether the sell-off was overblown and pointed out that the share price decline could create opportunities for investors looking beyond dividend considerations.

Tower Operators as Winners

Russ Mould, Investment Director at AJ Bell, told Investing.com that SpaceX's foray into mobile communications aligned with the company's overall business strategy. The combination of low- and mid-frequency spectrum could challenge traditional network operators and mobile infrastructure providers.

According to Wall Street analysts, mobile tower operators benefit from SpaceX's expansion of Starlink Mobile. Tower operator shares rose following disclosure of the deal. SpaceX requires terrestrial infrastructure for its hybrid architecture—specifically, locations on towers and rooftops where it can install radio equipment and antennas. Tower operators lease such locations to mobile network operators and could generate higher revenues through additional contracts with SpaceX.

Regulatory Hurdles Remain

All aspects of the transaction are subject to FCC approval before SpaceX can begin implementation. The regulator examines in such procedures, among other things, whether spectrum usage serves the public interest and is compatible with existing frequency allocations. Until approval is granted, the specific timeline for network expansion remains unclear.
