Alphabet shares plunged as much as 13% after the Google parent reported a $9.1 billion free cash flow outflow in the third quarter, driven by surging AI infrastructure spending and a slowdown in core search advertising growth. Net profit available to common shareholders fell about 25%.
The stock’s drop on October 29, 2026, erased roughly $500 billion in market value—its largest one-day decline on record and weighed on broader tech indices. Shares had already fallen more than 10% in after-hours trading following the results release on October 28.
Alphabet reported third-quarter revenue of $127.6 billion, up 25% year-over-year but short of the roughly $128.2 billion Wall Street had expected. Google advertising revenue came in at about $82 billion, missing estimates by around $1.4 billion.
Search advertising growth decelerated notably (one measure showed roughly 12% growth), with executives citing greater use of AI Mode—the company’s conversational search interface, as a factor that currently generates lower ad monetization than traditional results.
Net income available to common stockholders fell to $26.2 billion from about $35 billion a year earlier. Diluted earnings per share were $2.12; adjusted EPS of $2.67 also missed consensus targets near $3.02.
A large portion of the profit decline reflected non-cash losses on equity investments rather than core operations. Operating income, by contrast, rose about 30% to roughly $40.6 billion.
The standout pressure point was cash generation. Operating cash flow declined 13% to $42.3 billion while capital expenditures more than doubled to $51.4 billion—primarily for data centers, servers, and networking to support AI.
This produced negative free cash flow of $9.1 billion, following a $5.9 billion deficit in the prior quarter. Trailing twelve-month free cash flow fell sharply.
It marked only the second consecutive quarter of negative free cash flow for the company in more than two decades as a public firm.
Google Cloud provided a bright spot, with revenue more than doubling to $30.7 billion (about 103% growth). Demand for AI infrastructure and related services remained strong, and the unit’s backlog was described as substantial. Management pointed to this as evidence of corporate adoption of its AI offerings.
Investors, however, focused on the combination of decelerating search growth and accelerating cash burn.
Analysts noted that in a market already wary of AI potentially cannibalizing Google’s dominant search franchise, the results heightened questions about whether heavy AI investment is additive or dilutive in the near term.
One portfolio manager observed that investors need to see search accelerating rather than decelerating for the narrative to improve.
CFO Anat Ashkenazi indicated that capital spending would rise further in 2027 and flagged near-term margin pressure from the use of third-party cloud capacity. The company had previously raised significant capital to fund its AI buildout.
The sell-off reflects wider investor scrutiny of Big Tech’s AI spending race. Alphabet is investing heavily to stay competitive with rivals in models, infrastructure, and enterprise offerings, but the scale of outlays—now routinely exceeding cash generated from operations—has shifted attention from growth to returns and capital discipline.
Search remains the primary profit engine funding much of this expansion, making any sustained slowdown particularly sensitive.
Alphabet continues to emphasize its full-stack AI approach, recent model advances including Gemini updates, and long-term opportunities in cloud and AI-powered products.
For now, the market has signaled clear discomfort with the short-term trade-offs visible in the third-quarter numbers.
