Market Response and Competitive Landscape

The earnings announcement triggered a dramatic market response, with Amazon's stock surging 12% over four trading days and adding approximately $300 billion in market value

. This rally has pushed the stock to its first record high since February, addressing investor concerns about AWS losing ground to competitors. Despite this success, Amazon faces intensifying competition from Microsoft Azure, which recorded 40% growth, and Google Cloud, which expanded 34% during the same period

Analysts note that while competitors are growing faster, AWS's scale advantage remains significant. As Jassy explained, "It's very different having 20% year-over-year growth on a $132 billion annualized run rate" compared to higher percentage growth on smaller revenue bases
