Wireless stocks are usually where investors go when they want a quiet holding. On Friday, October 9, 2026, they were anything but quiet. The three largest U.S. carriers lost billions in market value in one session after Elon Musk's SpaceX announced a spectrum deal that brings its Starlink Mobile service closer to competing with them directly.
On the evening of Thursday, October 8, 2026, SpaceX said it had agreed to buy 100% of Grain Management's nationwide 800 MHz spectrum portfolio. That's up to 14 megahertz of paired low-band spectrum. The Wall Street Journal reported the price at about $8.00 billion in cash, though the companies did not disclose terms. Low-band spectrum travels long distances and gets through walls and trees, which has been a key weakness for satellite-to-phone service. Most current handsets already support the 800 MHz band. SpaceX said the deal will help Starlink Mobile become "a major mobile carrier in the US." The deal still needs approval from the Federal Communications Commission (FCC).
One detail stands out: Grain bought this same spectrum from T-Mobile in August 2026. In the same week as the deal, the FCC also approved SpaceX's application to launch 15,000 satellites designed to work with its existing 2 GHz spectrum. FCC Chair Brendan Carr told CNBC on October 9, 2026, that "it's not for us ultimately to pick winners and losers." The selling spread overseas too. Reuters reported that Deutsche Telekom fell 8% and Europe's telecom index hit its lowest level since February.
Verizon Communications (NYSE: VZ)
CNBC reported that Verizon was on pace for its worst day since 2002. As of midday on October 9, 2026, VZ traded at $41.31, down 9.49% from the prior close of $45.64. The market cap is $172.49 billion and the P/E ratio is 10.76. The stock is 7.61% above its 52-week low of $38.39 and 20.07% below its 52-week high of $51.68.
Verizon pushed back on the threat. A company spokesman said: "This company can have tons of spectrum available, but if they do not have the network to use it, it doesn't matter. It's just empty airwaves." Scotiabank kept its Sector Outperform rating on October 9, 2026, and trimmed its target to $50.00 from $51.50. The average analyst target of $51.25 implies about 24.06% upside.
AT&T (NYSE: T)
AT&T fell 10.11% to $22.11 by midday on October 9, 2026, from a prior close of $24.59. Its market cap is $151.47 billion, and its P/E ratio of 7.34 is the lowest of the three carriers. The stock is 11.16% above its 52-week low of $19.89 and 24.90% below its 52-week high of $29.44.
Scotiabank cut its AT&T target to $26.50 from $27.50 on October 9, 2026, with a Sector Perform rating. On the bullish side, BNP Paribas upgraded the stock to Outperform with a $30.00 target on September 21, 2026, and Morgan Stanley rates it Overweight at $28.00. The average target of $28.17 implies about 27.41% upside.
T-Mobile US (NASDAQ: TMUS)
T-Mobile fell the hardest. It traded at $149.72 midday on October 9, 2026, down 12.60% from $171.31. The market cap is $160.61 billion and the P/E ratio is 15.67. The stock is now just 1.08% above its 52-week low of $148.12 and 35.19% below its 52-week high of $231.02.
Analysts are still positive on T-Mobile, but they have been lowering their targets. Scotiabank cut to $212.00 from $217.00 on October 9, 2026, after an earlier cut on October 2. Barclays lowered its target to $200.00 from $215.00 on September 29, 2026. JP Morgan is at $260.00, the high end of the range. The average target of $224.00 implies about 49.61% upside. That's a wide gap from today's price, and it suggests analysts haven't fully updated their views since the news.
How Big Is the Threat?
Analysts see a real risk, but most think it will build slowly. Morgan Stanley called the deal "a clear sign that SpaceX is going to be a more aggressive acquirer of spectrum." The firm also said the threat to carriers will likely show up first in rural markets. Competing in cities would take much more ground infrastructure and spectrum. Analyst Tim Farrar of TMF Associates said the new spectrum is "still a very limited amount." He said SpaceX would need towers on the ground to get reliable indoor coverage in cities.
Starlink is already large. CNBC reported that it had 12 million subscribers across 205 countries as of June 30, 2026. In that period, Starlink earned $1.66 billion in operating income on $4.29 billion in revenue. William Blair analysts expect SpaceX to offer a "very compelling" bundle of Starlink broadband and Starlink Mobile. The three carriers have formed their own satellite joint venture, and Starlink is not part of it.
Tower companies may benefit from the shift. Reuters reported that American Tower, Crown Castle and SBA Communications rose 5% to 6% on October 9, 2026. Morgan Stanley called the deal "incrementally constructive" for tower owners, since even a satellite-focused network needs towers, rooftops and small cells.
What to Watch
The FCC review of the Grain deal is the first checkpoint. On October 29, 2026, the FCC will also vote on seeking public comment on a proposal to open up 482 MHz of additional spectrum for coverage from space. Carrier third-quarter earnings reports later in October will show whether management teams address the Starlink threat directly. Investors will also be watching each company's subscriber growth and pricing.
