Alphabet Shares Plunge as AI Spending Outpaces Cash Generation

On October 28, 2026, Google parent Alphabet saw its shares plunge after the release of their third quarter earnings report. Investor concerns centered around rising artificial intelligence expenses and underwhelming advertising revenue. Alphabet’s mounting infrastructure costs have raised questions about the profitability of AI investments. 

Alphabet reported quarterly revenue of $127.6 billion, a 25% increase year over year but below Wall Street's expectation of $128.2 billion. Net income declined 25% to $26.2 billion, while adjusted earnings per share of $2.67 missed analysts' estimate of $3.02. Shares fell more than 10% in after-hours trading following the announcement.

Adding on to investor concerns was their advertising business which failed to meet expectations. Google advertising generated $82 billion in revenue which missed its mark by $1.4 billion. This creates uncertainty over whether the increasingly growing use of AI-powered searches will affect Google’s traditional business model. Google relies majorily on consumers clicking the links showed to them when they search something up to generate revenue. However, artificial intelligence can give direct answers immediately causing Google to lose potential earnings from sponsored links. As the company itself also shifts to features driven by AI, investors will be watching whether the company can maintain advertising profitability while changing search behavior. 

Meanwhile, Alphabet’s AI infrastrucutre investments have placed substantial pressure on cash flow. This recent quarter, the company reported a negative free cash flow of $9.07 billion which was a huge decline from the reported positive cash outflow of $5.9 billion the quarter before. Furthermore, spending is expected to increase further in 2027. 

Despite these challenges, Google Cloud remained a bright spot. Quarterly revenue more than doubled from $15.2 billion to $30.7 billion, exceeding analyst expectations. Operating income also climbed from $3.6 billion to $11.1 billion, reflecting growing enterprise demand for AI infrastructure and cloud computing services.

This contrast reflects on Alphabet’s central challenge. While AI investments do generate massive revenue, the money put in to data centers, computing infrastructure, and advanced models to make this happen are offsetting the earns. 

With infrastructure investment expected to continue growing, Alphabet will need to show investors that its rapidly expanding AI business can eventually generate enough cash to justify its costs.
