SpaceX buys 800 MHz low‑band spectrum for Starlink Mobile, sending AT&T, Verizon and T‑Mobile shares tumbling

SpaceX announced an agreement with Grain Management to purchase up to 14 MHz of nationwide 800 MHz low‑band spectrum, a deal that still requires FCC approval. The acquisition is intended to let Starlink Mobile compete directly with the three largest U.S. wireless carriers. In after‑hours trading, AT&T, Verizon and T‑Mobile each fell between 5% and 8%. Elon Musk called the transaction a “very big deal.”

The sharp post‑announcement sell‑off reduces the market value of the three telecom stocks by roughly $5‑$7 billion in total, creating a buying opportunity for investors who view the dip as a temporary reaction. The spectrum purchase also signals a new competitive threat to the carriers’ wireless businesses, which could affect future revenue and margin outlooks.
