A Chinese AI lab wiped a trillion dollars off the market's whiteboard, and earnings season crowned the same winner as always. DeepSeek's R1 model, built for a fraction of Silicon Valley's budgets, triggered a January 27 selloff that erased nearly 600 billion dollars from Nvidia alone as investors questioned whether the AI infrastructure boom was overbuilt, days after Stargate had bet half a trillion dollars that it was not. Telecom earnings told a steadier story: T-Mobile closed 2024 with its best customer growth ever, 903,000 postpaid phone adds in the fourth quarter and industry-leading service revenue growth, while AT&T's results showed fiber and 5G convergence compounding, closing a quarter in which the Big Three's playbooks, and their gaps, were fully on display.
Power changed hands, and telecom's referee changed with it. President Trump was inaugurated January 20 and designated Brendan Carr chairman of the FCC the same day, installing a chairman with a published agenda: aggressive spectrum revival, satellite acceleration, deregulation, and a combative posture toward Big Tech. Among the first executive orders was a 75-day enforcement pause that brought TikTok flickering back to life, deferring rather than resolving the divest-or-ban standoff. The new administration's industrial ambitions arrived a day later at the White House, where OpenAI, Oracle, and SoftBank announced Stargate, a plan to spend up to 500 billion dollars on US AI data centers, a number that would reshape demand for power, fiber, and land before a single model trains.
The outgoing administration spent its final full week hardening the digital walls, and the courts turned off an app used by 170 million Americans. The FCC, in Chairwoman Rosenworcel's closing days, voted to declare that federal wiretap law obligates carriers to secure their networks, the agency's most direct regulatory answer yet to the Salt Typhoon intrusions, over Republican objections that guaranteed the ruling a short life. The Supreme Court unanimously upheld the TikTok divest-or-ban law on January 17, and by the night of January 18 the app had gone dark for US users, the most consequential government action against a communications platform in the internet era, with service providers and app stores suddenly on the legal front line.
The year opened with a spectrum coup, a customer promise, and the annual Las Vegas hardware pilgrimage. AST SpaceMobile started 2025 by securing long-term access to up to 45 megahertz of premium L-band spectrum through a deal with bankrupt Ligado Networks, paying 550 million dollars to give its satellite constellation something no direct-to-device rival owns: dedicated licensed spectrum of its own. AT&T launched the AT&T Guarantee, promising automatic bill credits for network outages across wireless and fiber, a first among the majors and a direct response to its damaging 2024 outage. And CES 2025 wrapped in Las Vegas with AI stitched into everything, from Nvidia's consumer superchips to connected cars, all of it presuming ubiquitous connectivity someone has to sell.
