TLDR
- Verizon (VZ) stock fell 7% in after-hours trading to $43.25 after SpaceX agreed to buy nationwide low-band spectrum from Grain Management.
- The spectrum deal could let Starlink Mobile penetrate buildings and expand coverage across almost the entire U.S. population.
- AT&T and T-Mobile stock also dropped sharply in extended trading on the same news.
- KeyBanc kept a Sector Weight rating on Verizon earlier in the day, citing only modest revenue growth ahead.
- The move comes weeks before Verizon’s Q3 earnings report on October 26.
Verizon stock dropped 7% in after-hours trading on Thursday, falling to $43.25. The decline followed SpaceX’s announcement that it had reached a deal to acquire a nationwide spectrum portfolio from Grain Management.
Verizon Communications Inc., VZ
The agreement covers up to 14 megahertz of paired low-band spectrum in the 800 MHz range. That spectrum is valuable because it travels further and penetrates buildings better than higher-frequency signals, something Starlink’s existing satellite network has struggled with.
SpaceX said the deal “addresses one of the key remaining technical gaps” standing between Starlink Mobile and becoming a major U.S. wireless carrier. CEO Elon Musk called it a “very big deal” in a post on X.
Why Investors Are Worried
Investors read the announcement as a direct threat to Verizon’s core wireless business. Low-band spectrum is the backbone of nationwide coverage, and SpaceX now has a credible path to building out its own network rather than just supplementing phone carriers through partnerships.

The timing stung too. Just last week, Verizon, AT&T and T-Mobile formed a joint venture to expand satellite and direct-to-device coverage in underserved areas. Starlink was left out of that venture entirely, and T-Mobile has reportedly scaled back references to Starlink in its own satellite marketing.
Industry analyst Tim Farrar of TMF Associates offered some pushback on the scale of the threat. He noted the spectrum amount is still limited, and SpaceX would need ground-based towers to get reliable coverage in dense urban areas.
Wider Market Context
The broader market gave Verizon no shelter. The S&P 500 closed up just 0.1%, the Dow was roughly flat, and the Nasdaq rose 0.2%. That means the telecom selloff was driven entirely by the SpaceX news, not any wider economic worry.
AT&T and T-Mobile stock also tumbled in extended trading, confirming the reaction was a sector-wide repricing rather than a Verizon-specific issue. The deal still needs FCC approval before it can move forward.
Earlier in the day, before the SpaceX news broke, KeyBanc reiterated its Sector Weight rating on Verizon. The firm pointed to improving metrics like lower customer churn and higher average revenue per account, but it only expects modest revenue acceleration through year-end.
The SpaceX announcement also landed just a day after the FCC said it would vote on auctioning 25 megahertz of spectrum for direct-to-device satellite services, and a further vote planned for October 29 on an additional 482 MHz of spectrum. Both proposals could further help SpaceX, along with Amazon’s own satellite ambitions.
SpaceX itself didn’t finish the day in the red. After dropping 4% during regular trading hours, SpaceX stock rose about 2.5% in after-hours trading on the spectrum news.
For Verizon, the combination of events pulled the stock well below its 52-week high of $51.68 and closer to the lower end of its annual trading range. The company’s Q3 earnings report, due October 26, will be the next test of whether subscriber growth and revenue trends can hold up against the new competitive backdrop.
SpaceX has not said when any new Starlink Mobile services enabled by the spectrum deal might launch, pending regulatory approval.
