Why SpaceX's Phone Plans Sent Big Phone-Company Stocks Down

Verizon shares fell 8.75% on October 9, 2026, their worst single-day drop since 2002. CNBC reported the same day that T-Mobile fell 13.27% and AT&T fell 9.81%. All three major U.S. phone companies lost a lot of value in one session.

Reuters described the drop as hitting telecom stocks in the US and Europe. It linked the selloff to SpaceX's activity in spectrum. Spectrum is the set of radio airwaves that phones use, and companies need licenses to use it.

Not every stock fell. Telecom tower operators, the companies that own the tall masts and sites where phone equipment sits, moved the other way. Investors were betting that SpaceX's wireless plans could eventually need more tower space.

Why would towers be on the other side? The Wall Street Journal reported on October 8 that Starlink, SpaceX's satellite service, needs ground equipment to provide mobile coverage. A satellite can carry a signal, but spectrum licenses alone do not put service on a phone. Someone has to host the radios on the ground, such as on cell towers or rooftops.

Then came the newer report. On October 22, Bloomberg published an article saying SpaceX was in talks to access 80,000 cell sites for a new wireless network. Investor's Business Daily reported that SpaceX was reportedly looking to secure at least 80,000 cell sites. Crown Castle and American Tower shares jumped on the news, while Verizon and AT&T shares fell.

The number matters because it is roughly the size of network a national carrier needs to offer wide coverage. It would give SpaceX a way into ground equipment without building all of it from scratch.

Spectrum is the other piece. Reuters reported on October 16 that SpaceX agreed to buy Grain's nationwide 800 MHz portfolio for about $8 billion. This is low-band spectrum, which a mobile company needs to reach phones indoors and in rural areas. An agreement to buy is not the same as a finished deal, though.

This is not a sudden change in direction. Bloomberg reported on June 26, 2026 that SpaceX and Charter had discussed a mobile phone partnership in the US. In July, the Wall Street Journal reported that SpaceX's Starlink unit planned to target mobile customers, and its president talked about building a ground network for the service.

The idea of connecting phones straight to satellites goes back further. SpaceX began deploying Starlink satellites with Direct to Cell capability in January 2024, aiming to end mobile dead zones, which are places with no signal. The newer satellites carry a modem that acts like a cellphone tower in space. In 2022, SpaceX and T-Mobile had also planned to link Starlink satellites to phones on the ground.

Government spending is a third thread. Reuters reported on October 16 that the Pentagon has spent billions of dollars on Starlink and Starshield services, and has bought dedicated Starshield satellites. That gives SpaceX revenue and experience separate from consumer phone service. On October 14, Eutelsat shares rose 23% by 13:55 GMT, their biggest one-day gain in 16 months. Reuters tied that session to Ukraine's curbs on Starlink military-grade service.

In my view, the moves fit together, even though nobody knows how this ends. The phone company drops reflect a scenario where satellite service takes customers from regular networks or pushes prices down. The tower gains reflect another scenario, where the satellite company still has to rent ground space from someone, and tower owners collect rent either way.

Think of a tower company as a landlord. It gets paid for its space no matter which tenant wins. A tower company does not need SpaceX to win the phone market. It only needs SpaceX to need sites.

The numbers need careful handling. "At least 80,000" is a reported figure about talks, and Bloomberg's headline treats it that way too. Spectrum purchases, partnership talks, and satellite capacity are each steps before a working service exists. For savers and pension holders who own these stocks, prices have swung sharply over just a few trading sessions.

For ordinary customers, the practical question is whether satellite phone coverage gets sold as an add-on or included in existing plans. That is still unanswered. The price moves of the past two weeks tell us more about what investors expect than about what people will end up paying.
