Amazon to Close Mechanical Turk to New Customers this Year
Amazon announced it will cease accepting new users for Mechanical Turk, its crowdsourcing platform, with new sign-ups ending on 30 July 2026.
The modification, revealed on the Mechanical Turk site, comes after what Amazon Web Services termed a choice made following “thoughtful deliberation.”

Amazon stated that current customers will be able to use the service as they did previously. In a statement, AWS mentions, “Current customers can keep using the service as usual. AWS is still focusing on enhancing security and availability for Mechanical Turk, but we do not intend to add new features. The phrasing indicates that although the platform will still be accessible to existing users, it is essentially on a prolonged maintenance trajectory instead of a path for acquiring new clients.
Originally introduced in 2005, Mechanical Turk was designed as a platform where human workers completed minor, specific tasks that were hard to automate. Common tasks involved finishing CAPTCHA tasks and recognizing the fundamental sentiment conveyed in a sentence.
As time progressed, businesses utilized the platform for data annotation, a method Amazon started emphasizing more clearly in 2018, branding Mechanical Turk as a solution for companies to ready data for training neural networks. The model of the platform was simple: requesters submitted groups of brief tasks, workers took on and finished them for minimal compensation, and the outcomes were combined to produce large quantities of labeled data

For two decades, Mechanical Turk has been central to discussions regarding the equity and clarity of crowdsourced labor. Observers and rights defenders examined the inadequate pay and conditions faced by certain workers on the platform, and the service was involved in broader privacy and political issues; it had a minor role in the initial phases of the Facebook-Cambridge Analytica scandal.
These discussions coincided with a time when organizations increasingly relied on human annotation to develop and improve machine learning systems. Amazon’s messaging evolved from a general-purpose crowdsourcing marketplace to focusing on data labeling for machine learning tasks, a transition that started to be highlighted publicly from 2018 onward.
For companies currently utilizing Mechanical Turk, the announcement assures continuity, as AWS pledges to uphold security and availability for current accounts.
Nonetheless, Amazon’s clear declaration that it has no intention of adding new features suggests that there will be no additional functional advancements, and customers should not anticipate new functionalities or enhancements.
For potential new clients, the deadline of 30 July 2026 serves as a definitive cutoff. Organizations intending to start using Mechanical Turk must find other providers or develop internal capabilities for data annotation and similar human-in-the-loop tasks. For employees depending on the platform for microtask earnings, the short-term effect may be minimal, as current tasks and clients can still function, but the choice constricts the possibilities for demand expansion on the platform.

The notification was posted on the Mechanical Turk site and establishes 30 July 2026 as the date when the service will stop taking new clients. The platform's beginnings date to 2005, and in 2018, Amazon started to more vigorously market Mechanical Turk as a data labeling tool, mirroring the growth of neural networks and supervised learning techniques. The service’s past also features significant examination of labor conditions and a marked engagement in the initial stages of the Facebook-Cambridge Analytica scandal.
Amazon’s decision concludes a phase for the platform as an accessible marketplace for newcomers, but retains existing operations. Currently, Mechanical Turk will remain available for existing users, but the absence of scheduled feature development leaves its future uncertain.
