News Summary:

T-Mobile shares declined on October 9, 2026, following news that Elon Musk's SpaceX entered the telecom business by acquiring spectrum. SpaceX agreed to buy a nationwide portfolio of up to 14 megahertz of paired 800 MHz licenses from investment firm Grain Management, a move that put pressure on T-Mobile and other dominant U.S. wireless carriers. Earlier the same day, ransomware group BYOD threatened to expose T-Mobile, listing the company on its site, although the group had not released any data samples. This threat emerged after BYOD breached Trump Mobile last week, publishing data from 3,615 users. T-Mobile serves approximately 142 million U.S. customers.
