An illegal market.
A market for products that are illegal, stolen, or otherwise need to be hidden from regulatory authorities. A black market encompasses the horrific (e.g. human trafficking) as well as the more mundane (e.g. participating in the market to evade taxes). Legal products on a black market are usually less expensive than on the regulated market because sellers do not pay taxes on their goods and services. That said, there is little or no recourse for the customer if and when a black market product fails. It is worth noting that black markets tend to be largest in jurisdictions where there are the most regulations and government monopolies. It is also known as an underground market.
