Amazon Shuts Down Mechanical Turk After 21 Years
Mechanical Turk shutting down September 30
Amazon announced that Mechanical Turk, its pioneering crowdsourcing marketplace, will permanently close on September 30, 2026. Launched in 2005, MTurk enabled businesses to outsource microtasks—like data validation, content moderation, and AI training data annotation—to a global, on-demand workforce. The decision follows a routine evaluation of programs and services. Workers and requesters are directed to an FAQ for guidance on preparing for the shutdown.
We regularly evaluate our programs, tools, and services and make adjustments based on those assessments.

Mechanical Turk had a good run, but not surprised it's shutting down. I'm sure the platform was getting flooded with people doing task arbitrage and using lots of AI anyway.
I believe the issue is that this can no longer be a horizontal play. MTurk was mostly for unskilled tasks...the kind AI can do well enough that it isn't worth the cost differential to verify it or keep farmed to humans. The "trust but verify" AI output is now the kind that requires domain expertise. This is what most full stack AI companies are bringing to industries.
Curious if this kind of work will come around again one day or was just a moment in time. If it does I'm sure it will be specifically about generating training data.

As AMT's largest requester for the past 10 years, this news was relayed to requesters at the same time as respondents. It's also worth noting that our lead contact, the Sr Program Manager at AWS leading AMT, transitioned to Amazon Bedrock and SageMaker Model Evaluations a ~2-3 years ago.. Leaving behind essential zero team managing the project after they migrated over the stored value accounts to native AWS billing.

So, I have a story to share about Mechanical Turk that you might find interesting. I’ve shared it a couple of times before on Twitter and Bluesky, but I’ll share it again.
Long story short: Mechanical Turk saved my bacon.
Back in 2005, I was working a job at a small-town newspaper in a town I’d never lived before. I didn’t know anyone beyond the staff (as I was working layout rather than as a reporter), and I had gotten interested in the idea of doing Mechanical Turk for a few extra bucks. I thought there might be a formative scene of interested people doing this, so I started working on a blog for it. I briefly collaborated on it with another guy who put it on forum software because he didn’t know how to use, like Drupal.
That blog was called Turking.com, and it seemed like it was going well for a bit. We even got a mention on the AWS website. But after about two or three months, it was clear the initial excitement around the idea (and the initial work) had died down. (The work picked up later, but in clearly different ways. I don’t think folks were really “excited” about it after that point.)
If you want to get an idea of it, there was one capture on the Wayback Machine: https://web.archive.org/web/20051124231722/http://www.turkin...
The site had started to die out in part because my iBook suffered a catastrophic GPU failure and me, being a broke small-town newspaper employee, did not have the money to replace it. Plus, the community just hadn’t emerged like we had expected […]

It’s kind of crazy they’re shutting this down just when this Service probably has the most possibilities ever. You have an agent with Multiple people doing actual physical tasks in the real world seems like something that could be really powerful.

I'll still be around on Oct 1.
