Could data collected by one company be useful to another? A data marketplace gives companies a public place to offer or acquire data. It is a type of data exchange: unlike an arrangement between two companies or a private exchange for selected participants, it is open to any company that wants to supply or consume data. Some marketplaces span many industries and types of data. section 6.6.1
Think of an exchange as a place where suppliers and buyers can find one another rather than negotiate every connection from scratch. Finding data is only part of the job: participants also need to address ownership, price, trust, security, and oversight. Those questions matter when an organization wants to turn data it holds into a product someone else can use. section 6.6 section 1.5.4
Electricity data on an exchange
When the Shanghai Data Exchange was announced in 2021, its first listings included 20 data products across eight industries. State Grid Shanghai described using exchange rules to offer processed electricity-data products intended to meet security requirements and buyer demand. The example shows that a listing is not just raw information: rules and preparation affect whether it can be traded. section 6.6
Do not assume today’s marketplaces already give you an easy way to sell your own data. Commercial exchanges are still developing; much of the available data comes from established list brokers, company catalogs, and government Open Data. A broader vision links exchanges with data commons and intermediaries that could help individuals manage, share, and earn from their data. That shift is a proposed direction, not an established feature of every marketplace. section 6.6.1 section 1.6
