Amazon stock falls 10% after $200 billion AI spending plan announcement

Amazon’s Massive AI Investment Plan Spooks Investors

Amazon shares took a sharp dive in after-hours trading on Thursday, dropping more than 10% and falling below the $200 mark. The sell-off came despite the company reporting solid fourth-quarter earnings that actually met analyst expectations. What really rattled investors was the announcement of a massive $200 billion capital expenditure plan for 2026, with a heavy focus on artificial intelligence infrastructure.

I think this reaction shows how sensitive the market is right now to big spending announcements, even from tech giants. Amazon’s revenue for the quarter climbed to $213.4 billion, with net profit hitting $21.2 billion. The company pointed to a strong holiday season and impressive 24% year-over-year growth in its AWS cloud business as key drivers. But all that good news got overshadowed by the spending outlook.

Strong Earnings Overshadowed by Spending Concerns

The numbers themselves were actually quite solid. AWS generated $35.6 billion in Q4 revenue, continuing its strong performance. Amazon also provided guidance for the first quarter of 2026, forecasting revenue between $173.5 billion and $178.5 billion, with operating income expected between $16.5 billion and $21.5 billion.

But here’s the thing—investors seem to be looking past the current performance and focusing on what’s coming. The $200 billion capex plan is enormous, even for a company of Amazon’s size. It represents a significant commitment to AI infrastructure at a time when there are already concerns about whether all this AI investment will pay off.

Cost-Cutting Measures Continue Amid Expansion

What’s interesting is that Amazon is pursuing what seems like contradictory strategies simultaneously. On one hand, they’re planning this massive spending spree on AI infrastructure. On the other, they’re continuing with cost-cutting measures that include closing underperforming units and laying off workers.

The company confirmed that the 16,000 job cuts announced last week are part of these broader streamlining efforts. It’s a bit of a mixed message—spending huge amounts on future growth while cutting costs in other areas. Perhaps this is just how large corporations operate these days, but it does create some confusion about their overall direction.

Broader Tech Sector Concerns

The sell-off isn’t happening in isolation. There’s growing concern across the tech sector about ballooning AI-related investments. Companies are pouring billions into AI infrastructure without clear timelines for returns. Amazon’s announcement just amplified those existing worries.

What strikes me is how quickly investor sentiment can shift. One minute, strong earnings would typically drive stock prices up. The next, a spending announcement sends shares tumbling. It suggests that markets are becoming more cautious about long-term investments, even when they come from established players like Amazon.

The company now faces the challenge of convincing investors that this $200 billion investment will pay off. They’ll need to show concrete progress and returns from their AI initiatives to justify such a massive outlay. Otherwise, they might continue to face pressure from shareholders who are growing wary of unchecked spending in the AI space.
