Alphabet shares fell 12.64 percent on October 29, 2026, in the steepest single day drop since the company went public in 2004. Alphabet shares closed at $283.82, down $41.07 from the prior close of $324.89, after the Google parent reported third quarter results on October 28 that missed Wall Street sales forecasts. The fall wiped out about $500 billion in market value, according to the Motley Fool, and Bloomberg estimated an intraday reduction of about $511 billion when the stock was down about 13 percent in morning trading. Alphabet shares in the Class C line fell 12.29 percent on the same day. The loss was the second largest one day market value loss for a United States listed company, behind only Nvidia’s $593 billion drop in January 2025.
Alphabet shares and the earnings miss
Alphabet shares fell even though total revenue rose 25 percent from a year earlier to $127.6 billion, while operating income rose 30 percent to $40.6 billion. Analysts had expected $128.2 billion in sales, so Alphabet fell short of the forecast even as revenue grew. Google Search revenue rose 12 percent to $63.4 billion, down from 17 percent growth in the second quarter and below a consensus of about $65 billion. Growth in paid clicks on search ads slowed to 8 percent from 13 percent in the second quarter. The Motley Fool said the slowdown supports a view that chatbots such as ChatGPT and Claude are becoming alternatives to Google for some users, which could affect advertisers.
Alphabet shares also reflected a fall in net income available to common shareholders, which fell to $26.17 billion from $34.98 billion a year earlier, a drop of about 25 percent. Diluted earnings per share were $2.12, down from $2.87 a year earlier. Part of that decline came from losses on equity securities, including an unrealized investment loss tied to Space Exploration Technologies. Alphabet reported about $8.7 billion in losses on equity securities, with an after tax effect of about $6.7 billion on net income. Those investment losses are separate from profit in the company’s core advertising and cloud operations.
Alphabet shares hit by AI spending
Spending was the deeper worry behind Alphabet shares for investors. Alphabet generated $42.3 billion in operating cash flow in the third quarter, but capital expenditure totaled $51.4 billion, leaving a free cash flow deficit of $9.1 billion. That was the second negative quarter in a row for free cash flow, the first such run since the company’s listing, according to Reuters reporting cited in market coverage. Capital spending more than doubled from a year earlier, driven by new data centers, added computing power and investment in custom silicon. Management raised the 2026 capital expenditure budget to $195 billion to $205 billion and said spending is expected to increase further in 2027.
Alphabet shares also reflected funding moves, as Alphabet raised about $12.4 billion through common stock issuance and about $28.7 billion through debt issuance in the third quarter to support its infrastructure plans. Issuing more shares can dilute existing holders, while more borrowing raises future interest payments. Alphabet’s quarterly filing also disclosed contingent commitments of about $98.5 billion, up about $23 billion from the prior quarter, according to Bloomberg. Pepperstone analyst Chris Weston, quoted by Reuters, said the market is not necessarily questioning whether the buildout can be financed, but is asking whether the returns will match the cost.
Alphabet shares and the cloud offset
Google Cloud gave investors in Alphabet shares a counterweight to the search shortfall. Cloud revenue more than doubled to $30.7 billion, up 103 percent from a year earlier, and operating income in the segment rose to $11.1 billion, more than triple the year earlier figure. The cloud operating margin widened from 23.7 percent to 36.2 percent in one year. Google Cloud’s order backlog closed the quarter at about $561 billion. Management pointed to interest in its Tensor Processing Units, the custom chips built for artificial intelligence training and inference, from Anthropic, Apple, Meta Platforms and Oracle, as well as from Citadel Securities and Jump Trading.
The Gemini application now reaches 1 billion users, Alphabet said, while its artificial intelligence model APIs process 32 billion tokens per minute, more than four times the volume a year earlier. Gemini is integrated into Google Search, Workspace and Android. Previous worst losses for Alphabet in dollar terms were about $275 billion on July 23, according to Yahoo Finance calculations cited in market coverage, so the October 29 drop exceeded that figure by a wide margin. Alphabet alone has lost about $1.4 trillion in market value since reaching its record in May, Yahoo Finance calculations showed. Amazon was scheduled to report earnings after the close on October 29 as the last major cloud provider to report that week.
