Week of January 27–31, 2025Telecom Intelligence: Week of January 27, 2025
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.
