Amazon Stock Dips as Cheaper AI Model Hits AWS

Amazon's stock price has fallen by about 1.1% to $246.84 per share on September 28, following the introduction of Claude Opus 5.5, a cheaper AI model, on Bedrock and the Anthropic platform on AWS. The new model costs 20% less per token than its predecessor, with an estimated typical workload costing about 40% less due to fewer tokens used.

Amazon's shares are now 1.11% below their GF Value estimate of $249.61, indicating that investors are closely watching the impact of this price cut on AWS growth and margins. While a lower cost for AI tasks could attract more customers, it may also lead to reduced revenue per task.

The success of Claude Opus 5.5 will depend on whether increased usage makes up for the decrease in revenue per task. With zero-data-retention support by default through Bedrock and Anthropic's native platform on AWS, users can now access this cheaper AI model without worrying about data storage costs.
