T-Mobile Stock Down 14.5% Amid SpaceX Fears, but Telecom Expert Says Selloff Is Overdone

Key takeaways

• T‑Mobile’s sharp decline is driven by speculative fears of SpaceX entering the mobile market, but experts believe the reaction is overdone and the real impact may be limited.
• T‑Mobile down 14.5% since Oct. 8
• SpaceX eyeing 80,000 U.S. cell sites
• $20 billion infrastructure cost estimate

What happened

T‑Mobile shares fell 14.5% since Oct. 8 after reports that SpaceX is eyeing 80,000 U.S. cell sites, sparking fears the satellite‑based company could become a fourth nationwide carrier. The drop followed a brief slide in AT&T (‑8%) and Verizon (‑1.2%).

Why it matters

The sell‑off reflects investors’ concern that SpaceX’s potential entry could erode the market share and earnings of the existing carriers. If SpaceX were to launch a mobile plan, it could force the incumbents to lower prices and cut margins, impacting their long‑term profitability.

Short-term and longer-term

Short-term. Over the next few days, T‑Mobile’s stock could rebound as the market digests the Q3 earnings report.

Longer-term. In the coming months, the long‑term impact on T‑Mobile will depend on whether SpaceX actually launches a mobile plan.
