London Stock Exchange Group is a financial markets infrastructure and data company. Although its name comes from the exchange it operates, the majority of its revenue today comes from selling data, analytics and workflow software to financial institutions, and from clearing and post trade services rather than from trading fees alone. Its customers include banks, asset managers, hedge funds, corporations, regulators and central banks.
The London Stock Exchange itself traces its origins to coffee house trading in the seventeenth century and was formally constituted in 1801, which makes it one of the oldest exchanges in the world. The modern group took its present shape through a series of acquisitions, most significantly the purchase of Refinitiv in 2021, which brought the financial data terminal business formerly owned by Thomson Reuters, and the earlier acquisition of a controlling interest in LCH, one of the largest clearing houses in the world. The group is headquartered in London and is a constituent of the FTSE 100 index. It employs roughly 25,000 people across more than sixty countries.
The business is organised around several divisions. Data and Analytics supplies real time and historical market data, reference data, indices, and the Workspace terminal used by traders and analysts. Capital Markets operates the equities, fixed income and foreign exchange trading venues, including Tradeweb and FXall. Post Trade covers clearing and risk management through LCH, which clears a very large share of the world's interest rate swaps. The group also owns FTSE Russell, a major index provider whose benchmarks are tracked by substantial pools of invested capital.
A strategic partnership with Microsoft, announced in 2023, has directed much of the group's recent engineering investment toward moving data infrastructure to the cloud and embedding analytics and generative artificial intelligence into the workflow products that traders and analysts use daily.
The technical work is characterised by very large data volumes, strict latency requirements in the trading and clearing systems, and regulatory obligations that govern how data is stored, distributed and audited. Engineers there deal with real time streaming architectures, time series storage, entity resolution across reference data, and the resilience engineering required by systems that regulators treat as critical infrastructure.
India is one of the group's largest technology locations, with substantial centres in Bengaluru and Hyderabad. Roles cover software engineering, data engineering, quantitative and index research, site reliability, cybersecurity, product management, and financial and regulatory operations.
