Amazon will stop accepting new Mechanical Turk customers on July 30, 2026. The 21 year old marketplace paid gig workers pennies for micro tasks that generative AI now does at near zero cost.
Amazon will stop accepting new customers for Mechanical Turk on July 30, 2026. The marketplace, launched in 2005, was Amazon's standing joke about fake AI: pay humans to do the work a machine could not yet do, and call the result "artificial artificial intelligence" until the machine arrived. The machine has arrived.
On June 30, Amazon posted a brief notice on the Mechanical Turk site: "Amazon Mechanical Turk will be closed to new customers, effective July 30, 2026." Existing users would not be affected. The AWS SageMaker developer guide added that the company "continues to invest in security and availability improvements for Mechanical Turk, but we do not plan to introduce new features." That phrasing is the entire story in two sentences: no shutdown, no retirement date, just a frozen roadmap and a closed front door.
Amazon named Mechanical Turk in 2005 after Wolfgang von Kempelen's eighteenth-century chess automaton, a wooden cabinet that toured Europe and beat human opponents until a chess master was exposed inside the box. The service became known, as Gizmodo reported, as "artificial artificial intelligence"—meaning human labor impersonating a not-yet-built machine. Workers earned between one cent and a few dollars per "human intelligence task," the platform's name for the micro-tasks that could not yet be automated: audio transcription, object identification in satellite images, restaurant contact verification, image labeling for model training. The marketplace also seeded the freelance-labor category, Gizmodo notes, paving the way for Fiverr and Upwork.
The work MTurk paid pennies to outsource is now within the routine capability of multimodal generative models. Audio transcription, object identification in satellite images, restaurant contact verification, and image labeling for model training all run as standard API calls at near-zero per-task cost. The displacement happened because the work was always structured enough for automation, and the cost floor was always the issue. Generative AI removed the cost floor.
Three outlets covered the closure within a week. TechCrunch reported the cutoff on July 5, The Register ran a piece headlined "not even AI can save it" on July 3, and Dataconomy followed on July 6. The Register's headline is the cleanest statement of the underlying mechanism. The platform's structural premise was always temporary, and AI did not have to rescue it.
New Scientist reported years ago that automated bots posing as workers had corrupted psychology research samples drawn from MTurk. The platform's worker base was anonymous, low-paid, and easy for software to impersonate, which meant buyers of MTurk labor were often paying human-task prices for bot output. Generative AI did not need to beat skilled human labor to displace the marketplace. It only needed to beat the bot-infested version of human labor that the marketplace had already become.
SageMaker Ground Truth still lists Mechanical Turk as an available managed workforce for data labeling, and Amazon's developer documentation treats the integration as current rather than deprecated. The standalone marketplace for researchers, small requesters, and ad-hoc labeling jobs is the part contracting. The platform-as-pipe for AWS customers is the part Amazon is still willing to maintain. That split tells you who the real customer base became over the past decade, and it is a narrower audience than the one that found the service useful in 2005.
Amazon has not, in either the public notice or the developer guide, named a migration target for existing requesters who relied on the open marketplace. If SageMaker Ground Truth becomes the only sanctioned route, the academic survey researcher and the start-up that needed a thousand labeled receipts will both have to rebuild on AWS, or leave. The AWS services maintenance page does not yet list Mechanical Turk as a retired service, which is consistent with managed contraction rather than hard shutdown.
Amazon posted the closure notice on June 30 and the cutoff is July 30, 2026. The marketplace, for now, is the same service it was a month ago, with one change: no one new gets to sit inside. That is the structural endpoint for any layer of tech infrastructure whose entire reason to exist was to wait for a smarter machine to arrive.
