Our take
The London Stock Exchange is one of the world’s oldest stock exchanges, with a history dating back over 300 years. It operates as a part of LSEG (London Stock Exchange Group), one of the world’s leading providers of financial markets infrastructure, as a marketplace to enable stock brokers and traders to buy and sell stocks, bonds, and other securities.
The London Stock Exchange has lived through a stream of innovations; from telegraph and telephone, to the Market Price Display System, automatic trade matching, and the digitisation of issuer services. In 2019 it acquired Refinitiv, a financial information company, and in doing so became a global financial news and data business.
Most recently, the London Stock Exchange has made moves to support the evolution of private markets, and further build its presence in this space. It partnered with Floww, a platform that connects investors with private companies, with aims to launch a private primary capital raising facility, as well as explore new technologies and secondary market options for the platform.
