Shares of AT&T, Verizon and T-Mobile have been sliding on and off for two weeks as analysts grow more convinced that SpaceX's push into direct-to-phone satellite service poses a genuine competitive threat to the traditional wireless carriers, rather than a niche add-on confined to rural coverage gaps.
The trigger was SpaceX's early-October agreement to acquire a nationwide portfolio of low-band spectrum from Grain Management, covering up to 14 megahertz of paired 800 MHz licenses, giving its planned Starlink Mobile service the kind of spectrum foothold it previously lacked. The deal still requires FCC approval before it can close, but the market reaction was immediate: AT&T and Verizon each fell roughly 10% in the days after the announcement, and T-Mobile dropped as much as 13% in a session traders described as one of its steepest declines in years.
Analysts Turn More Bearish
The pressure has not let up. This week, Bernstein downgraded AT&T from Outperform to Market Perform and cut its price target to $24, citing rising Starlink competition, pricing pressure and seasonal fourth-quarter headwinds, while Scotiabank separately lowered its own AT&T price target, calling SpaceX's hybrid satellite-and-terrestrial network a credible long-term threat to carrier valuations. AT&T shares fell again this week even after the company beat on both earnings and revenue for the quarter and raised its full-year guidance, as investors focused instead on postpaid phone subscriber growth that came in below expectations and on vendor-dispute settlements the company said would weigh on fourth-quarter earnings.
Not every voice on the Street is convinced the threat is immediate. AT&T's own chief executive has described the dynamic with Starlink as "complementary" rather than purely competitive, and T-Mobile's chief financial officer has said he is "not worried" about Elon Musk's cellular ambitions, pointing to the years of infrastructure build-out and regulatory approvals still standing between SpaceX and a fully competitive consumer wireless product.
A Real Threat, on a Long Fuse
Profitability for Starlink Mobile itself remains years away by most estimates, which is part of why some analysts view the sharpest stock reactions as overdone. But the spectrum deal removes one of the clearest technical obstacles SpaceX faced in building out a true nationwide satellite-to-phone network, and it lands at a moment when traditional carriers are already fighting to defend pricing power against a wave of lower-cost competitors. Whether or not Starlink Mobile meaningfully dents carrier revenue any time soon, Wall Street's reaction over the past two weeks suggests investors are no longer willing to treat the threat as hypothetical.
