US Earnings Season: Big Tech Spending Fears Hit Alphabet and Amazon
Cloud revenue is booming, but AI capital spending is eating free cash flow. Why investors punished strong growth this quarter.
The short answer: The third-quarter US earnings season has shown strong revenue growth at Big Tech, but investors punished heavy AI spending. Alphabet's revenue rose 25% to $127.6 billion, yet its shares fell more than 10% on weaker free cash flow. Amazon's AWS grew 39%, but the company kept its $220 billion spending plan and its trailing free cash flow turned negative. Meta beat revenue estimates. The message: growth alone is no longer enough; investors want to see returns on AI investment.
US earnings season: the Big Tech scorecard
| Company | Reported | Headline result | Investor focus |
|---|---|---|---|
| Meta | Oct 21 | Revenue beat estimates; strong guidance | Daily users of 3.64 billion, slightly below forecasts |
| Alphabet | Oct 28 | Revenue +25% to $127.6bn; EPS $2.12 | Free cash flow fell; shares down more than 10% |
| Amazon | Oct 29 | Net income $20.7bn; AWS +39% | Trailing free cash flow negative; $220bn capex plan |
Figures come from company releases and filings. Microsoft also reported on October 28, and Apple's results were expected in early November.
Why it matters: these companies make up a large share of the S&P 500. When their shares move sharply, index funds and retirement accounts move with them.
The AI spending question
Big Tech companies are spending unprecedented sums on chips, data centers and power to run artificial intelligence services. Amazon alone plans around $220 billion of capital spending in 2026. That spending shows up immediately as cash going out, while the revenue it generates arrives over years.
Cloud growth suggests demand is real: Google Cloud more than doubled its revenue, and AWS grew at its fastest pace in years. But free cash flow, the money left after capital spending, is shrinking or negative. Investors are asking whether returns will justify the costs, especially with interest rates rising.
Yes, but: heavy investment cycles have rewarded patient investors before, as with early cloud computing. They have also ended in overcapacity, as with telecom networks in 2000. Nobody knows yet which pattern AI will follow.
Why shares fell despite growth
Markets trade on expectations. Analysts had expected higher adjusted earnings from Alphabet, and the drop in free cash flow surprised investors. When a stock is priced for perfection, even good results can lead to sharp falls. Our guide on how to read an earnings report explains why guidance and cash flow often matter more than headline profit.
Beyond Big Tech
Earnings season covers hundreds of companies. Rate-sensitive sectors face higher borrowing costs, while consumers are feeling higher gasoline prices. Banks can benefit from higher rates through wider lending margins, and industrial companies tied to data center construction and power have seen strong demand. This rotation helps explain why the Dow rose in October even as the Nasdaq fell.
What it means for valuations
When profits stay strong but spending rises and rates go up, investors usually pay less for each dollar of earnings. That means lower price-to-earnings multiples for growth stocks. If you want to understand how that works, read our explainer on the price-to-earnings ratio.
How investors can respond
- Look at cash flow, not only earnings per share.
- Check concentration: many index funds hold a large share in a few tech giants.
- Think long term: one quarter rarely changes a company's long-term prospects.
- Diversify across sectors and regions; see index funds vs active funds.
What to look for in the next reports
Several large companies still report in November, including retailers and Nvidia, whose chip sales reflect how much the rest of Big Tech is spending on AI. Watch three things: whether cloud growth stays strong, whether capital spending plans for 2027 rise again, and whether companies give clearer timelines for when AI investments will generate profits. Strong answers could restore confidence; vague ones may extend the sell-off.
The bottom line: This US earnings season shows Big Tech growing fast but spending even faster on AI. Investors rewarded cloud growth less than they punished falling cash flow, a sign that the market now wants proof that AI investment will pay off.
Frequently asked questions
What is free cash flow?
Operating cash flow minus capital spending. It shows how much cash a business generates after investing in its future.
Why does AI spending hurt share prices?
Large spending reduces near-term cash and raises questions about future returns, especially when interest rates make cash more valuable.
When does earnings season end?
Most large US companies report within about six weeks of the quarter's end, so third-quarter season runs into mid-November.
Should I sell tech stocks after a bad earnings season?
Reacting to one quarter is risky. Review whether the long-term business case has changed, check how concentrated your portfolio is, and rebalance to your plan rather than trading on headlines.
