Amazon just dropped its Q3 earnings, and while the top-line numbers beat Wall Street expectations with $180.2 billion in revenue, the real story is the thunderous return of Amazon Web Services. After a period of sluggishness that had investors worried Amazon was losing the AI arms race to Microsoft and Google, AWS roared back to life, posting 20% year-over-year growth, a pace not seen since 2022.

CEO Andy Jassy made it clear that this isn't a fluke. "AI drives meaningful improvements in every corner of our business," he said in a statement. The evidence is in the numbers and the tech. AWS sales hit $33.0 billion, fueled by what the company describes as "strong demand in AI and core infrastructure." This demand is being met by a massive build-out, including custom silicon like its Trainium2 AI chip, which Amazon claims is now a multi-billion-dollar business that grew 150% in a single quarter.

The company is also flexing its AI muscle with Project Rainier, a colossal compute cluster with nearly 500,000 Trainium2 chips dedicated to training Anthropic's Claude models. This, combined with new AI business tools and a contact center AI solution that's now a $1 billion run-rate business, paints a clear picture: Amazon's expensive, long-term bet on building its own AI ecosystem is starting to pay serious dividends.

## The high cost of an AI future

Despite the blowout quarter, Amazon's stock dipped slightly in after-hours trading. Investors are likely eyeing the costs behind the curtain. The company's operating income was hit by a $2.5 billion legal settlement with the FTC and another $1.8 billion in severance costs tied to recent layoffs.

Those layoffs, which have cut 14,000 corporate jobs, loom large over the AI-powered success story. While Jassy frames the cuts as creating a "leaner" culture, it's hard to ignore the timing as the company pours an estimated $125 billion into capital expenditures this year, largely for AI and automation. The Amazon Q3 earnings report shows a company successfully navigating economic headwinds by leaning into AI, but it also reveals the steep price of that transition, both in capital and, potentially, in its human workforce.
