Elon Musk’s SpaceX triggered one of the most punishing weeks for traditional telecom stocks in recent memory, erasing tens of billions in combined market value.
AT&T (T), Verizon (VZ), and T-Mobile (TMUS) shares all came under severe pressure after reports emerged that SpaceX plans to launch a Starlink-branded retail mobile service for U.S. consumers.
The sell-off was brutal across the board, with Verizon falling 7%, AT&T sliding 5.8% to $21.41, and T-Mobile dropping 6% to $171.78 in heavy trading.
AT&T touched its 52-week low of $21.29 during the session, while T-Mobile recorded a decline of 28% on a one-year basis, making it the worst performer among the three carriers.
Barron’s reported that $15.74 billion was wiped from AT&T’s market cap alone, contributing to a staggering $46 billion combined slide across the three major carriers.
The panic originated on June 26, when the Financial Times reported that SpaceX President Gwynne Shotwell told IPO roadshow investors the company intends to build its own terrestrial wireless network under the Starlink brand.
Satellite connectivity has historically been limited to emergency services or remote regions lacking cellular infrastructure, but SpaceX is now targeting mainstream smartphone users directly.
The prospect of a satellite-powered consumer network threatens the core business model of carriers that have spent decades investing hundreds of billions of dollars into physical cell towers and fiber-optic systems.
SpaceX and Charter Communications (CHTR) also held executive-level talks about partnering on a consumer mobile phone offering, Bloomberg reported, which could accelerate SpaceX’s push into direct-to-consumer wireless.
TD Cowen analyst Gregory Williams noted that T-Mobile would be the “clear choice” for SpaceX if it cannot reach a wholesale network deal, or if Musk’s firm would rather own a wireless business outright.
Oppenheimer analyst Timothy Horan downgraded AT&T from Outperform to Perform, removing his price target entirely and citing low-earth-orbit satellite constellations as a structural threat to long-term broadband and mobile subscriber growth.
Horan argued that AT&T is the most exposed U.S. carrier because it leans hardest on broadband, making the Starlink threat particularly acute for the Dallas-based telecom giant.
Verizon faced additional headwinds beyond the SpaceX news, as BT Group and Verizon announced a 50:50 joint venture combining their international enterprise operations in a deal valued at $625 million.
Verizon was also removed from the Dow Jones Industrial Average, a symbolic blow that compounded already deeply negative investor sentiment surrounding the stock.
SpaceX has not confirmed a launch timeline or pricing structure for its consumer Starlink mobile service, leaving Wall Street to price in an uncertain but potentially transformative competitive threat.
