London Stock Exchange Group
The London Stock Exchange Group plc (LSEG) is a British financial markets infrastructure and data company that operates stock exchanges, clearing houses, trading platforms, financial data services, and index businesses. Headquartered in London, the group traces its origins to the London Stock Exchange, which was established in 1801. LSEG was formed in 2007 through the merger of the London Stock Exchange plc and Borsa Italiana S.p.A., creating one of the world's leading providers of capital market infrastructure and financial information. The company is publicly listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.
LSEG operates a diversified portfolio of businesses across global financial markets. Its principal operations include the London Stock Exchange, Borsa Italiana, FTSE Russell, LCH (London Clearing House), Tradeweb Markets (minority stake), Refinitiv, and the Workspace financial information platform. Through these businesses, the group provides services including securities trading, derivatives clearing, post-trade settlement, market data, financial analytics, benchmark administration, and index licensing. The acquisition of Refinitiv in 2021 significantly expanded LSEG's presence in financial information, risk management, and data analytics, positioning it as a major competitor to providers such as Bloomberg L.P. and S&P Global.
The London Stock Exchange Group plays a central role in the global financial system by supporting capital formation, investment, risk management, and price discovery across international markets. Its infrastructure serves financial institutions, governments, corporations, asset managers, and investors in more than 190 countries. LSEG is regulated by financial authorities in multiple jurisdictions and is an active participant in international market initiatives through organizations such as the World Federation of Exchanges (WFE). The group's combination of exchange operations, clearing services, benchmark indices, and financial data has made it one of the world's largest financial market infrastructure providers.
