Amazon Web Services announced it will cease accepting new customers for Mechanical Turk on July 30, 2026. The decision follows a period of careful consideration, with AWS stating that existing customers can continue using the service without interruption. However, the company will not introduce new features and will focus on security and availability improvements. The move signals a significant shift for the platform, which has been in operation since 2005.
Mechanical Turk, originally designed as a crowdsourcing marketplace for simple, human-centric tasks, has evolved into a critical tool for data annotation in AI development. Companies have used it to train neural networks through Amazon’s SageMaker service, and it has also been linked to the development of AI products that rely on human labor masked as automation. The platform’s role in AI has grown more complex over time, with some workers and researchers abandoning it due to concerns about bot activity and data integrity.
The platform’s history is marked by ethical debates, including its role in the early stages of the Facebook-Cambridge Analytica scandal. A 2023 analysis revealed that between 33% and 46% of Mechanical Turk workers used large language models to complete tasks, raising questions about the reliability of data generated on the platform. This week, a Reddit user suggested the platform had already died years ago, with workers and researchers leaving due to fraud and bot activity. The user predicted that Amazon might eventually shut down the service entirely.
