SpaceX 800 MHz Spectrum Deal Rattles AT&T, Verizon, T-Mobile
SpaceX (SPCX) acquired 14 MHz of 800 MHz spectrum from Grain Management, aiming to enhance Starlink's mobile service. AT&T (T), Verizon, and T-Mobile shares fell up to 7% after-hours. The deal requires FCC approval. SpaceX's recent 10-Q showed a Q2 2026 net loss of $541m, narrower than the prior year. Short interest in SPCX rose before the announcement.
