Why SpaceX entering telecom rattles AT&T, Verizon, and T-Mobile
As seen on the 24/7 Wall St. homepage on November 9, 2026.
The big 3 telecoms operate in the US only. SpaceX automatically can cover any country on earth that let's them in. Why does Reddit keep missing this point Also telecom companies aren't undervalued at all, they have literally no growth potential in the US. They can at best siphon customers in between themselves but that's about the max growth they can do.
The top-voted reply reframes Starlink Mobile as a global land grab no domestic carrier can match, against a bear case that assumes a saturated US market. If that view wins, the big three are defending a market with nowhere left to grow.

A widely discussed r/investing thread is wrestling with a question that cuts to the heart of domestic telecom valuations: what AT&T, Verizon, and T-Mobile face if SpaceX is chasing a global addressable market none of them can reach.
The original post frames a forced choice: either the big three are massively undervalued, SpaceX is massively overvalued, or the total market for telecom services is about to grow in ways not yet priced in. Analysts have openly joked that SpaceX could buy each of the big three outright multiple times over, which makes entering a low-margin, saturated business look strange on its face.

The top-voted reply, which scored 324 points, argues the domestic carriers are boxed in, capable only of trading customers among themselves, while SpaceX can serve any country on earth that permits it. If Starlink Mobile gets the launch economics right, the ceiling on its growth has little to do with the US market at all.
For investors holding the domestic carriers, the competitive threat will not show up in next quarter's subscriber numbers. It shows up slowly, in rural markets first, then in underserved international ones, without the big three having a credible infrastructure answer.
