The inquiry, which commenced nearly one year ago, during the tenure of former President Joe Biden, scrutinised the startup’s fair pay practices and working conditions, Scale AI said in March 2025.

In response to the closure, Scale AI said it was “pleased” with the update from DOL, reported TechCrunch.

Scale AI, established in 2016, specialises in providing accurately labelled data crucial for training advanced AI tools like OpenAI’s ChatGPT.

The startup also offers a platform for AI research exchange, boasting contributions from more than 9,000 cities and towns globally.

In the previous year, Scale AI secured $1bn in a late-stage funding round led by Accel, with NVIDIA, Amazon, and Meta also participating.

The funding, which elevated the company’s valuation to approximately $14bn, is aimed at enhancing data capabilities for enterprise clients, the US Department of Defense, and supporting the DEFCON 31 red-teaming event announced by the White House.

The funding round also saw investments from prominent entities including Coatue, Tiger Global Management, Intel Capital, and AMD Ventures.

This followed a $325m series E funding round in 2021, which at the time reportedly valued Scale AI at around $7.3bn.
