NEW DELHI [NCRBuzz Wire] — NEW YORK [NCRBuzz Wire] — **US telecom giants AT&T, T-Mobile, and Verizon experienced severe market capitalisation losses of up to 11% in intra-day trading following a disruptive move by Elon Musk's private aerospace manufacturer and space transportation services company, SpaceX.** The aggressive equity sell-off was triggered by market apprehensions over SpaceX's strategic expansion into cellular connectivity via newly acquired low-band spectrum assets.

**Market analysts and quantitative desks noted that the equity downturn reflects immediate investor repricing of long-term ARPU (Average Revenue Per User) and subscriber retention risks for traditional wireless carriers.** The spectrum in question, acquired from Grain Management, provides a vital regulatory foundation for Starlink to deploy direct-to-cell satellite communications at scale without requiring legacy ground infrastructure modifications.
