The definition of 'AIM Alternative Investment Market'

Launched in 1995, the AIM market – which at the time stood for the Alternative Investment Market – is the London Stock Exchange’s growth market, created to assist smaller companies in raising the capital they need to scale up. Also referred to as London’s junior market, AIM replaced the Unlisted Securities Market (USM) and began operating with ten companies listed, with a combined market cap of £82.2m. In just over 20 years, the exchange has grown to encompass around 1,000 companies and a combined market cap exceeding £90bn.

AIM is often considered the most successful growth market in the world.
