Who buys AI training data?
Frontier labs, neolabs, enterprises, startups and governments buy AI training data. What each buys, how they pay and where deals are reported.
The main buyers of AI training data are frontier labs, newer well-funded labs, enterprises, startups building on open models and government programs. They buy different things and pay in different ways. This guide describes each buyer type and where reported deals appear.
What do frontier labs buy?
A frontier lab trains the most capable general models and buys across the stack: licensed text and media for pretraining, expert and preference data for post-training, and evaluation sets. Frontier labs often negotiate private deals with publishers and platforms and sign large contracts with expert-data companies. Reported examples include the Reddit and Google license and the News Corp and OpenAI license on the deal tracker.
What do neolabs buy?
A neolab is a newly founded, well-funded AI research company. Neolabs tend to buy expert data and RL environments quickly and in volume, because they need to catch up on post-training.
What do enterprises buy?
Enterprises fine-tune open or hosted models on their own tasks. They buy domain datasets, expert annotation and evaluation sets, often through cloud exchanges such as AWS Data Exchange or through consultancies.
What do startups buy?
Startups building coding, legal, medical or voice products buy domain-specific data: code data, legal data and speech data. Budgets are smaller, so they favour catalogue datasets, per-task pricing and marketplaces.
What do governments buy?
Public-sector programs buy labeled data, evaluations and secure data infrastructure, usually through formal procurement, and have strict security requirements.
How do buyers find sellers?
They use expert-data companies, licensing marketplaces, cloud exchanges and direct outreach. The provider directory groups these by type. Sellers who want to reach them should read how to sell data to AI companies.
