Global Markets Update: Amazon Leads the Charge
In a mixed bag of economic news, Amazon's booming cloud computing business helped push the world's largest online retailer to new heights. However, a softer-than-expected sales outlook weighed on medical device firm Medtronic.
Amazon's Cloud Computing Surge
Amazon Web Services (AWS), the company's cloud computing arm, has been a key driver of its growth. On Friday, October 31, 2025, AWS reported significant revenue gains, sending Amazon's stock price soaring.
AWS Key Highlights:
- Revenue Growth: AWS generated $14.8 billion in revenue, up 28% year-over-year.
- New Customers: The company welcomed over 1 million new customers to its platform.
- Expansion into New Markets: AWS expanded its presence into new markets, including the Middle East and Africa.
The success of AWS can be attributed to the growing demand for cloud-based services. As more businesses shift their focus towards digital transformation, AWS is well-positioned to capitalize on this trend.
Amazon's Strong Q3 Results

Medical Device Firm Medtronic Suffers
Medtronic, a leading medical device firm, reported a softer-than-expected sales outlook. The company's revenue growth was slower than expected, and its stock price took a hit as a result.

- Guidance: The company provided a slightly weaker-than-expected sales outlook for the fourth quarter.
