In privacy law, a business selling personal data about people it has no relationship with; in AI data, an intermediary matching data holders with buyers.

The two meanings differ. Several US states regulate consumer data brokers. An AI data broker such as AI Data For Sale introduces business parties and supports a direct license. See [brokers vs marketplaces](https://aidataforsale.com/learn/ai-data-broker-vs-marketplace).
