Verizon, AT&T, T-Mobile US stocks sink, tech executive lashes out on SpaceX’s spectrum serve
SpaceX announced plans to acquire up to 14 MHz of 800 MHz spectrum from Grain Management, valued at $8 billion, to expand its Starlink Mobile service. This move caused shares of Verizon, AT&T, and T-Mobile US to drop significantly. T-Mobile US CTO John Saw criticized the deal, citing technical and financial challenges. The spectrum was previously owned by T-Mobile US and EchoStar.
