Amazon Shuts Down Mechanical Turk After 21 Years as AI Replaces Human Task Workers
Amazon announced the permanent closure of its Mechanical Turk crowdsourcing platform, effective September 30, 2026. Launched in 2005, the platform once employed over 500,000 workers for small digital tasks. The shutdown follows years of competition from specialized AI data-labeling firms and advances in AI that made many of its functions obsolete.
Amazon will permanently close its Mechanical Turk crowdsourcing platform on September 30, 2026, ending a 21-year run for a service that once employed more than 500,000 workers worldwide.
The company posted a notice on the Mechanical Turk website in August 2026 confirming the shutdown. Amazon stopped accepting new customers to the platform in July 2026. The company said the decision followed a regular evaluation of its programs and services.
Mechanical Turk launched in 2005 as a marketplace for small digital tasks that were easy for humans but difficult for machines. Workers, known as turkers, completed jobs like data labeling, audio transcription, and survey participation. Jeff Bezos famously described the platform as artificial artificial intelligence, a reference to the human labor powering what appeared to be automated processes.
The platform's decline accelerated as specialized data-labeling startups including Scale AI, Mercor, and Prolific emerged to serve the needs of modern AI model training. These companies offered more tailored services and higher-quality outputs than the general-purpose Mechanical Turk marketplace.
A 2023 study by Swiss researchers found that up to 46 percent of workers on the platform were using AI models to complete their tasks, raising concerns about data quality and authenticity.
The closure affects workers who relied on the platform for supplemental or full-time income, as well as businesses in the insurance and travel sectors that used it for data processing. Amazon has provided an FAQ page to help workers and clients manage the transition and resolve outstanding billing issues.
The shutdown marks the end of an era for human-powered digital labor platforms, as large language models and specialized annotation firms have taken over the functions Mechanical Turk once served.
