Why AT&T Stock Plunged on Friday

AT&T (T) fell 8% on Friday after reports that SpaceX (SPCX) is negotiating access to 80,000 U.S. cell sites to build a rival wireless carrier. The reported talks put a new, deep-pocketed entrant squarely in the frame for the incumbent carrier's stock.

The selloff reflects fear of competitive disruption, but the source points to a fundamentals picture that has not changed. AT&T posted strong Q3 earnings, continues to grow its customer base, and carries improving free cash flow projections. None of those data points were reversed by Friday's reports.

The barriers to a SpaceX-built network are also substantial. Building a nationwide carrier would require tens of billions of dollars in investment and significant time. Interpretation: an 8% single-day drop prices in a rapid competitive threat, while the source describes a multi-year, capital-intensive buildout. That gap between market reaction and execution timeline is the core debate for T holders.

The reports describe negotiations, not a finalized deal. Access to 80,000 cell sites would be a meaningful step, but it does not by itself produce a functioning nationwide carrier.
