Alphabet loses about $480 billion as shares fall 12% amid AI spending concerns
Key Facts
Alphabet lost about $480 billion in market value as its shares fell nearly 12% on Thursday, October 29, 2026, according to a Forbes estimate at 1:30 p.m. Eastern time. The magazine valued the company at $3.46 trillion at that point, before trading closed. At the same time, it estimated that Sergey Brin’s fortune had fallen by about $29 billion to $217.2 billion. The sell-off followed the quarterly results, as investors worried about the scale of AI spending and whether those investments could generate sufficient returns. The session showed that growth in the company’s businesses did not stop the market from focusing on the cost of its capital expansion.
The clearest pressure was on cash flow: Alphabet recorded negative free cash flow of $9.065 billion in the third quarter of 2026, after property and equipment purchases reached $51.355 billion. These figures matter in assessing the company’s ability to fund its expansion as it continues to invest in AI infrastructure. Investors focused on whether the costly investments would generate returns commensurate with their scale, Reuters reported via Investing.com. The company’s results, meanwhile, showed that some spending supports rapidly growing businesses, particularly cloud computing. But that did not ease market concerns about the relationship between current spending and cash flows.
Google Cloud revenue rose 103% to $30.7 billion in the third quarter year over year. Alphabet said growth came from expanding infrastructure, enterprise AI solutions and core GCP services, alongside sales of TPU systems. The results show that demand for cloud computing services remained a key business driver, while meeting that demand requires significant investment in equipment and infrastructure. The report therefore paired strong revenue growth with sharp pressure on free cash flow. That divergence kept the question of returns on capital at the forefront of investors’ reaction.
In search, revenue from Google Search and other advertising grew 12% in the third quarter of 2026 year over year, but that was below growth of 17% in the second quarter and 19% in the first quarter. Alphabet said search queries grew at their fastest rate in five years, supported by increased use of its services on mobile devices. The company also attributed search revenue growth to increased advertiser spending and improvements to ad formats and placement. These figures point to slower revenue growth than in the previous two quarters, not a contraction in activity. Market concerns about spending and returns thus coincided with continued search growth, albeit at a slower pace than at the start of the year.
The decline was reflected in the broader market during the October 29 session, with the Nasdaq down 1.4% and the S&P 500 down 0.3%, despite most stocks in the broader index rising. The Associated Press said Alphabet’s Class A shares had their worst day since beginning trading more than 20 years ago, falling 12.6%. The following day, the stock fell a further 1.4%, Reuters reported via Investing.com, as concerns continued over the cost and returns of AI investments. EL7 data show the sequence of closing prices: $324.89 on October 28, then $283.82 on October 29 and $279.84 on October 30. The Forbes estimates of the market value and Brin’s fortune losses were snapshots during trading, not final figures at the close.
Alphabet announced in October a quarterly cash dividend of $0.22 per common share, payable on December 14, 2026, to shareholders of record on December 7. The payment date comes weeks after the sell-off, while the quarterly results remain central to investors’ assessment of search and cloud growth against capital spending. The company has thus set a specific date for a cash distribution alongside an expansionary investment cycle whose cost showed up in third-quarter data. Property and equipment purchases of $51.355 billion were the direct mathematical driver of the free cash flow deficit recorded in the period. Monitoring the cash impact of these investments remains central to the market’s assessment of the company’s performance.
