AIData.Broker is a seller-side marketplace for AI training data, and a price board for the market around it. There is no price list for AI training data, so the site collects what is public: more than 700 prices paid, offered or listed for company records, source code, video, audio, images, text and datasets, each with its source and a per-unit figure; 25 buyers with what each publishes about price, eligibility and payment; 95 disclosed licensing deals; and a tracker of lawsuits and rulings over training data.
Free tools turn that evidence into answers: a data valuation for eight kinds of data, a rights check that shows what blocks a sale and what to fix, a buyer match, and a datasheet builder. Fourteen datasets are open under CC BY 4.0.
For holders who want to sell, AIData.Broker acts for the seller: it takes the data to several buyers, compares the bids and is paid a success fee from the sale (15% of the first $250,000, 10% from there to $1 million, 6% above), and nothing if nothing sells. AI labs and data vendors can post a request for data to be sourced, free.
Who it is for: companies, estates, creators and founders who hold data and want to know what it is worth to AI labs and how to sell it; AI labs and data vendors looking for licensed training data.
Key features: price board of 700+ sourced AI training data prices; market rates (medians) per kind of data; buyer board of 25 buyers and their terms; data valuation tool; rights check tool; licence terms reference; deal ledger of 95 licensing deals; lawsuits and rulings tracker; 14 open datasets (CSV and JSON, CC BY 4.0).

Alternatives and comparison: AIData.Broker is often compared with Datarade, Defined.ai, Opendatabay, Protege, Troveo, Wirestock, TollBit and Nomad Data. Those services cover parts of the same market, such as data marketplaces, licensing platforms and creator dataset deals. AIData.Broker focuses on the seller side of the market: what AI training data sells for, which buyers publish their terms, and what a holder should fix before a sale. The site launched on 11 October 2026 and is published in English for the web. Every price on the price board carries its source and a per-unit figure, so readers can check each number before relying on it. Prices, buyers, deals and lawsuits are updated as new public evidence appears, and each page links back to the sources it uses.
