Amazon Web Services (AWS) will stop accepting new customers for its Mechanical Turk crowdsourcing platform starting July 30, 2026, according to The Decoder. This move signals a gradual winding down of the service, which has been a key tool for businesses and researchers to outsource microtasks to a global workforce.

Mechanical Turk has played a significant role in data labeling, AI training, and other tasks requiring human intelligence at scale. The announcement from AWS indicates a strategic shift away from this particular crowdsourcing model, although existing users can presumably continue their operations until further notice.

For Japanese investors and companies involved in AI development and data services, this change may prompt a search for alternative crowdsourcing or data annotation platforms, potentially affecting operational workflows and costs in the local tech market.
