Verizon falls 7%, AT&T hits 52-week low as SpaceX and cable rivals converge

Investing.com -- Verizon Communications Inc (NYSE: VZ) is trading 7.6% lower at $43.02 and AT&T Inc (NYSE: T) has touched its 52-week low of $21.29, sliding 5.8% to $21.41, as three separate competitive threats collided on Monday to rattle investor confidence in legacy US telecom carriers. T-Mobile US Inc (NASDAQ: TMUS) is also under significant pressure, trading down 6% at $171.78 and testing its 52-week low of $169.00, making it the worst performer among the three carriers on a one-year basis with a decline of 28%.

The sharpest catalyst came from SpaceX, which told investors it plans to launch a Starlink mobile service for US consumers, the Financial Times reported on June 26, placing Elon Musk’s satellite company in direct competition with Verizon, AT&T and T-Mobile as a retail wireless carrier. SpaceX COO Gwynne Shotwell outlined the idea during the IPO roadshow. SpaceX secured licensed AWS-3 spectrum alongside the Big Three carriers in an auction whose results were posted on June 26 by the FCC, giving it the regulatory footing needed for a standalone mobile offering, though observers note it still lacks terrestrial tower infrastructure.

Adding another layer of disruption, Bloomberg News reported that SpaceX and Charter Communications held executive-level talks about partnering on a consumer mobile phone offering in the US, a potential alliance that would combine Starlink’s satellite reach with Charter’s extensive cable infrastructure. 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.

The Starlink threat arrived alongside a disclosure that unsettled Verizon investors further: BT Group and Verizon announced a 50:50 joint venture combining their international enterprise operations in a deal valued at $625 million, with Verizon paying that sum to BT as part of the arrangement. The official BT Group statement described the new entity as "a scaled international connectivity platform for multinational customers," but investors focused less on the strategic rationale and more on what it signals about Verizon’s capital allocation and balance-sheet flexibility at a moment when domestic network investment looks more urgent than ever.

Comcast Corp (NASDAQ: CMCSA)), meanwhile, broke sharply higher after announcing it will spin off NBCUniversal and Sky into a separate publicly traded company, separating its cash-generating broadband arm from media assets. CMCSA is trading up 7.2% at $24.84 on volume of over 62 million shares, roughly double its three-month average, as investors bid up the prospect of a purer-play broadband entity. The irony for Verizon and AT&T is that a leaner, more focused Comcast broadband business could prove a more formidable competitor to their fiber and fixed-wireless products, not a weaker one.

The broader competitive picture has darkened steadily. The Charter Communications acquisition of Cox Communications, approved by the FCC in February 2026, created the largest cable operator in US history, intensifying fixed-broadband rivalry against Verizon FiOS and AT&T Fiber from the cable side. The Comcast restructuring compounds that pressure by potentially freeing broadband capital from the drag of underperforming media assets.

Sentiment around Verizon carries an additional burden: Verizon was removed from the Dow Jones Industrial Average, a symbolic blow that added to negative momentum even as the stock’s dividend yield remained near 6% based on the prior close. At $43.02, VZ is trading well above its 52-week low of $38.39 but has retreated significantly from its 52-week high of $51.68.

AT&T’s technical picture is arguably more concerning to investors. The stock has lost more than 26% over the past year and is pressing against its 52-week low of $21.29 intraday, a level that chartists watch as potential breakdown support. A sustained close below that threshold would mark fresh multi-year lows and could invite further institutional selling.

Several questions remain unresolved for investors assessing the sector. SpaceX has not publicly confirmed a launch timeline or pricing for the consumer Starlink mobile service, meaning the threat today is priced on investor communications rather than a concrete product rollout. Analyst opinions have not yet surfaced, and fresh notes from firms covering VZ and T are likely to emerge later this week.

The immediate forward catalysts are the Comcast investor briefing, where details on the spinoff structure and broadband competitive positioning are expected, and the regulatory approval timeline for the BT-Verizon international JV, both announced June 29 with closing dates still to be confirmed. How aggressively Comcast’s standalone broadband arm chooses to compete on price and coverage will clarify the magnitude of the fixed-line threat to both carriers, while SpaceX’s next investor communication on Starlink mobile could either escalate or moderate today’s market reaction.
