Amazon Plunges After-Hours as Massive AI Spending Plan Overshadows Earnings Beat

Record Earnings Met with Skepticism

Amazon reported a robust first quarter after the close on Wednesday, with net sales rising 17% year-over-year to $181.5 billion, surpassing the $177.2 billion consensus estimate. Earnings per share (EPS) came in at a staggering $2.78, nearly 70% higher than the $1.64 analysts had projected. The company's core retail business showed resilience, but the star of the report was Amazon Web Services (AWS), which saw revenue grow 28% to $37.6 billion—its fastest growth rate in 15 quarters.

However, the stellar top- and bottom-line figures were not enough to satisfy investors in the extended session. The stock's 3.53% drop in after-hours trading reflects a "sell the news" reaction following a 30% rally over the past month, as the market grapples with the immense cost of Amazon's AI ambitions.

The $200 Billion AI Price Tag

The primary catalyst for the after-hours sell-off was management's commentary regarding capital expenditures. CEO Andy Jassy committed to a roughly $200 billion capex budget for 2026, a 60% increase over the previous year's spending. This aggressive investment cycle is aimed squarely at building out the infrastructure required for generative AI, including data centers and custom silicon like the Trainium and Inferentia chips.

This spending surge has already begun to impact the company's balance sheet. Amazon revealed that free cash flow for the trailing twelve months plummeted 95% to just $1.2 billion, down from nearly $26 billion in the year-ago period. For many investors, the sheer scale of the investment cycle raises concerns about near-term margin compression and the timeline for a meaningful return on investment (ROI) from these AI initiatives.

Broad Market Divergence and Sector Sentiment

Amazon's decline stands in sharp contrast to the broader market, as the S&P 500 (SPY) remained unchanged at +0.00% during the after-hours session. The 3.13% relative underperformance highlights that the move is driven by stock-specific concerns rather than macroeconomic trends.

Amazon was not alone in its struggle to impress; other "Magnificent Seven" peers like Microsoft and Meta also faced downward pressure in extended trading despite strong results. This suggests a high bar for the tech sector, where even significant earnings beats are being overshadowed by the rising costs of the AI arms race. With 65.2 million shares traded after the close, the high volume indicates that institutional investors are actively recalibrating their positions in light of the new spending guidance.

Looking Ahead

While the immediate reaction in extended trading was negative, some analysts remain bullish on the long-term prospects of Amazon's AI pivot. The company noted that its custom chips business has already reached a $20 billion annual revenue run rate, and a new deal with OpenAI to consume two gigawatts of Trainium capacity starting in 2027 provides a clear roadmap for future demand. However, until the company can demonstrate that this massive capex ramp-up will translate into sustained margin expansion, the stock may remain under pressure as investors weigh the cost of leadership in the AI era.
