Amazon is shutting down new signups for Mechanical Turk, a marketplace where companies hire people to do small online tasks. The deadline is July 30, 2026. People and companies already using it can keep going, but Amazon will not add new features or invest in the platform going forward.

Mechanical Turk has been around since 2005. It was created as a place for researchers and companies to find workers for jobs that computers could not yet do. The jobs were simple but needed a human judgment: labeling images, transcribing audio, deciding whether text is positive or negative. For nearly 20 years, it was where companies got training data to teach artificial intelligence systems.

What's Actually Happening

Amazon is not turning off the service overnight. It is stopping new customers while letting existing ones stay. That means if you use Mechanical Turk now, nothing breaks. But this is a slow fade, not a pause. When a company says it will only maintain "security and availability," that usually means the service is gradually going away. Smart teams should not count on this lasting forever.

Amazon's shift makes sense in the context of how AI works now. Modern AI systems can generate their own training data — they do not need as many humans to label images or transcribe recordings as they used to. Companies that still need human workers are now using specialized vendors with carefully chosen teams, not broad crowdsourcing platforms. The market for this kind of work has shrunk.

Why This Matters

Researchers in psychology, economics, and social science have depended on Mechanical Turk to find study participants. They could reach diverse groups of people online quickly and cheaply. Other platforms like Prolific and CloudResearch have grown specifically to replace it, and researchers will likely move there.

This announcement also fits into a bigger picture. Amazon announced job cuts affecting roughly 30,000 employees between October 2025 and January 2026. The company is focusing its energy on products that are growing. A 20-year-old crowdsourcing platform is not a growth business anymore.

Mechanical Turk's name came from an old trick: an 18th-century chess machine that looked automated but actually had a hidden person inside doing the work. For two decades, Mechanical Turk coordinated hidden human labor. Now the AI that Mechanical Turk helped train can do much of that work without humans. The quiet end of the platform is a fitting close to that story.

If you currently use Mechanical Turk, you should figure out where else you can get the same work done before the deadline. Other options include Amazon's newer SageMaker Ground Truth service, specialist vendors, or using AI to generate training data yourself.
