n. prediction market
Wikipedia
Although information has been bought and sold since ancient times, the idea of an information marketplace is relatively recent. The nature of such markets is still evolving, which complicates development of sustainable business models. However, certain attributes of information markets are beginning to be understood, such as diminished participation costs, opportunities for customization, shifting customer relations, and a need for order.
