What pushed Alphabet (NASDAQ:GOOG)'s Class C shares to the top of the most-active list on Thursday was a third-quarter report that left investors weighing a booming cloud Business against slowing search growth and a Capital spending bill that has turned free cash flow negative. GOOG closed at $282.32, down 12.29%, on 91.72 million shares, about five times its normal turnover based on a relative Volume reading of 5.03. That was roughly $25.9 billion of stock changing hands, more than any other US-listed name in the session. The Class A shares, GOOGL, fell by a similar amount, and one media headline described it as the worst day ever for shares of Google's parent.

What the quarter showed

Alphabet reported after the close on Wednesday, October 28. Revenue rose 25% to $127.6 billion, slightly below the roughly $127.9 billion analysts expected, according to consensus estimates. Operating Income rose 30% to $40.6 billion. Diluted Earnings per Share were $2.12, down from $2.87 a year earlier and well short of the roughly $3.02 the Street had forecast, according to one report.

Much of the earnings shortfall came from below the operating line. Alphabet booked an $8.7 billion loss on Equity securities, which cut EPS by about $0.55. One report said Chief Financial Officer Anat Ashkenazi attributed the loss mainly to the company's stake in SpaceX (NASDAQ:SPCX), whose shares declined during the quarter. The loss is unrealized, and a year earlier the same line produced a $10.7 billion gain.

The bigger concern for investors was Google Search. Search revenue grew 12% to $63.4 billion, a clear deceleration from about 17% growth in the second quarter and 19% in the first, and below the roughly 15% analysts had expected, according to market data. Chief Business Officer Philipp Schindler pointed in part to lower monetization of queries in AI Mode, the company's conversational search experience. Management also cited currency effects and softer retail Advertising spending in Asia. For a business that still generates about half of Alphabet's revenue, a slowdown tied partly to its own AI products struck at a core question about how generative AI changes the Economics of search.

A cloud business that more than doubled

Google Cloud produced the strongest numbers of the quarter. Revenue more than doubled to $30.7 billion, up 103% from a year earlier, and one report noted it was the sixth straight quarter of accelerating growth. Cloud operating income rose to $11.1 billion from $3.6 billion, putting the segment's Margin at about 36%. The cloud backlog climbed to $561 billion from $514 billion three months earlier. Chief Executive Sundar Pichai said in the release that Alphabet had "a strong quarter and are now on a half-trillion dollar revenue run rate." One analyst called the cloud figures "the Cloud print we have been waiting for," according to media reports.

That strength was not enough to offset the rest of the report. "The problem is everything else," one market strategist said.

The spending question

Capital expenditures reached $51.4 billion in the quarter, more than double the roughly $24 billion spent a year earlier and a record for the company. Free cash flow was negative $9.1 billion, deeper than the negative $5.9 billion reported for the second quarter. Alphabet kept its 2026 capital spending guidance at $195 billion to $205 billion, and Ashkenazi said spending will increase significantly in 2027. Media reports said some forecasts point to about $300 billion next year, with more detail expected when the company reports fourth-quarter results.

How that spending is being financed has also drawn attention. According to media reports, Alphabet raised $84.8 billion in equity in June, including $10 billion from Berkshire Hathaway (NYSE:BRK.B), and another report said the company sold $12.4 billion of stock and raised $28.7 billion in new Debt during the third quarter. One independent analyst said Alphabet "is now funding the AI buildout with shareholders' money instead of its own cash." For a company long valued for its large free cash flow, that change in the funding mix is a major reason the market reacted so strongly.

What Alphabet does and where it sits

Alphabet is the parent of Google, whose businesses include Search, YouTube, Android, Google Cloud and the Gemini AI models, along with smaller ventures. The company has two widely traded share classes: GOOGL (Class A, voting) and GOOG (Class C, non-voting). Both classes are constituents of the S&P 500, the Nasdaq-100 and the Russell 1000. In June, S&P Dow Jones Indices announced that Alphabet would join the Dow Jones Industrial Average, replacing Verizon (NYSE:VZ) effective June 29, 2026; the announcement named the Class A shares, GOOGL, as the Dow constituent.

Valuation after the drop

On market data, GOOG trades at about 14.7 times trailing earnings of $19.16 per share, with a Market Value of $3.47 trillion for the Share Class shown. That multiple is flattered by large Investment gains in earlier quarters, including the first quarter, when EPS reached $5.11. Even so, it compares with trailing multiples of about 27.7 for Microsoft (NASDAQ:MSFT), 21.3 for Meta Platforms (NASDAQ:META) and 19.6 for Amazon (NASDAQ:AMZN) on the same session data. One report put Alphabet at about 21 times forward earnings. Another noted that GOOGL was down about 9% for the year during Thursday's trading and almost 29% below its 52-week high of $402.62, set in May.

The bull and bear cases

The bull case rests on Google Cloud. A business growing more than 100% a year with a 36% Operating Margin and a backlog of more than half a trillion dollars gives investors a concrete return on at least part of the AI spending. Supporters also point out that much of the EPS miss came from a non-cash mark on the SpaceX stake rather than from operations, and that operating income still grew 30%.

The bear case centers on search and cash. Search growth has slowed for two straight quarters, and management's own explanation links part of the slowdown to how AI answers are monetized. Meanwhile, capital spending that may approach $300 billion next year has pushed free cash flow below zero, and the company is now issuing stock and debt to fund it. Investors who bought Alphabet for its self-funding cash machine now have to model a different kind of company.

What to watch next

The main near-term questions are whether search growth stabilizes in the fourth quarter, whether AI Mode monetization improves, and how big the formal 2027 capital spending guidance will be when Alphabet reports early next year. The size of the cloud backlog and how quickly it converts into revenue will also be watched closely. Further swings in the value of the SpaceX stake, which now trades publicly, could continue to move reported earnings from quarter to quarter. Thursday's volume suggests that large holders were actively repositioning, and analyst estimate revisions over the coming days may show how much of the reset is already reflected in the price.
