AI Investment Drives U.S. GDP to 3.4% Growth as Big Tech Stocks Crater $482 Billion in Single Day

The U.S. economy posted stronger-than-expected growth in the third quarter, expanding at a 3.4 percent annualized rate—its fastest pace in a year. But the same artificial intelligence boom driving that expansion is now rattling Wall Street and triggering questions about whether the growth figures tell the full story.

According to Breitbart’s Business Digest, real final sales to private domestic purchasers—considered the cleanest measure of underlying domestic demand—jumped 4.9 percent, marking the strongest quarter since pandemic-distorted figures in mid-2021. Yet some economists and media outlets have questioned whether AI-related spending inflates the picture of economic health.

Media Questions AI-Driven Growth

The Guardian suggested the robust GDP number “was probably not a true picture of the economy” due to the increasing dominance of AI-related spending. Breitbart called this assessment “crazy,” noting that even stripping out all AI investment, consumer spending alone contributed 2.52 percentage points of the 3.4 percent growth figure.

The numbers behind the AI boom are staggering. Nonresidential fixed investment—business spending on structures, equipment, and intellectual property—grew at a 12.7 percent annualized rate in the third quarter, contributing 1.78 percentage points to overall GDP growth.

Equipment investment surged even more dramatically, at a 20.9 percent rate, accounting for 1.16 percentage points of growth. Computers and peripheral equipment alone contributed roughly seven-tenths of a percentage point, reflecting massive spending on computing infrastructure for AI data centers.

The Offshore Manufacturing Problem

Breitbart noted a significant drag on growth: America’s reliance on imported technology. Net exports subtracted 3.32 percentage points from GDP, with a record-high share of imports coming from capital goods. The outlet suggested growth would be even higher if the U.S. hadn’t exported semiconductor manufacturing capacity to Asia, forcing domestic companies to import hardware to meet AI infrastructure demands.

Big Tech’s $482 Billion Meltdown

The same week that showcased AI’s economic impact brought catastrophic losses for the companies funding it. On Thursday, Alphabet shares plunged nearly 13 percent—the worst single-day performance since its 2004 IPO—erasing roughly $482 billion in market value.

Amazon followed with disappointing quarterly results that evening, missing expectations on both revenue and profits while posting negative free cash flow for a second consecutive 12-month period. The company maintained its plan for $220 billion in capital expenditures this year. Amazon’s stock fell about 1.5 percent Friday, adding to a four percent drop Thursday.

Intel suffered the worst fate. The chipmaker’s weak guidance, blamed on soft PC sales, rising memory costs, and a plant shutdown in Israel, sent shares down approximately 29 percent—reportedly the worst day for the stock since 1974.

The AI Investment Paradox

These divergent stories share a common thread: the enormous cost of AI investment. Years ago, investors celebrated when tech companies reinvested cash into their businesses. But after years of massive profitability, the surging cost of AI infrastructure is spooking Wall Street.

Intel’s situation highlights another dimension of the problem. While its AI-related processor sales are strong—the stock had been up about 150 percent for the year—its personal computer business looks troubled. The shift of computing power from laptops and desktops to data centers threatens Intel’s traditional revenue stream. As AI moves processing to remote supercomputers, consumers may need little more than basic screens with wifi connections.

Fed Chairman Kevin Warsh observed Wednesday, just before the megacap selloff began, that “market participants are becoming somewhat more discerning in their capital allocations.”

Public Skepticism About AI

Breitbart also highlighted growing public wariness of artificial intelligence, citing a New York Times profile of former Yahoo CEO Marissa Mayer, described as a Google “pioneer” and the company’s first female engineer. Mayer is now promoting Dazzle, an AI assistant that analyzes photos on users’ camera rolls.

In the profile, Mayer recounted asking her AI assistant for help describing her daughter Marielle for a school assignment. She felt “overwhelmed by the range and complexity” of coming up with three bullet points about her 10-year-old. The AI responded that her daughter was “empathetic, creative and an animal lover.” Mayer called the generic response “perfect.”

Breitbart suggested such anecdotes explain why AI has become “less popular than inflation” among Americans, despite the technology’s champions promising it will change everything.

Historical Echoes

The Business Digest concluded with a cautionary historical parallel. On October 30, 1929, the stock market staged one of its greatest rallies after John D. Rockefeller Sr. announced he was buying stocks, believing “fundamental conditions of the country are sound.” The Dow Jones Industrial Average soared 12.3 percent that day, followed by another 5.8 percent jump on October 31.

Bulls assured investors the panic was over and a buying opportunity had emerged. The Dow eventually lost nearly 90 percent of its value from its September 1929 peak to its July 1932 bottom as the country descended into the Great Depression.

Whether Thursday’s tech selloff represents a similar warning or merely a correction in overheated valuations remains an open question—one that will likely be answered as companies continue reporting results and clarifying their AI investment strategies in coming quarters.
