Amazon Shares Fall Amid Launch of Cheaper AI Work Platform

Amazon's stock price fell nearly 2.5% to $248.76 on Wednesday, following the launch of Claude Opus 5.5 on Bedrock, a native platform on AWS.

The reduced cost of AI work is expected to stimulate usage and potentially draw in more customers for production use, but investors will need to see whether this leads to increased demand and spending across AWS.

Claude Opus 5.5 costs $4 per million input tokens and $20 per million output tokens, which is a 20% reduction compared to Opus 5.

Anthropic estimates that users will save 40% on typical workloads due to the model's ability to use fewer tokens.
