London Stock Exchange Group plc runs the LSE, FTSE Russell indices, and Refinitiv data — processing trillions in trading volume under CEO David Schwimmer.
London Stock Exchange Group plc
London Stock Exchange Group plc was formed in 2007 through the merger of the London Stock Exchange and Borsa Italiana, creating a multi-asset exchange operator with a market capitalization exceeding $60B (per public record). The firm's CEO, David Schwimmer, took the helm in 2018 after previous roles at Goldman Sachs and the NYSE, overseeing the integration of Refinitiv — a deal that vaulted LSEG into the top tier of financial data providers alongside Bloomberg. LSEG's revenue streams span capital markets (equities, bonds, derivatives listings and trading), post-trade services (clearing and settlement via LCH and Monte Titoli), and data & analytics (Refinitiv's desktop terminals and FTSE Russell index business). The group operates across Europe, North America, and Asia, with offices in New York, Milan, Paris, and Hong Kong. Its FTSE Russell division publishes over 15,000 indices used by pension funds, sovereign wealth funds, and ETFs globally, while its FX trading platform FXall handles daily volume of about $200B. As of 2025, LSEG employs roughly 25,000 people across 70+ countries. In November 2024, the group announced the completion of its Microsoft partnership, integrating Azure-based cloud analytics for real-time market data clients. This followed a broader push into private markets via the 2023 acquisition of ClearPar, a private credit settlement platform, and the 2024 launch of LSEG Private Markets. LSEG's structural differentiator is its vertically integrated model — it owns the exchange, the index, the data terminal, and the clearing house. This gives it unique line-of-sight into capital flows, benchmark construction, and post-trade risk that no other exchange group replicates at similar scale. The group is regulated by the UK Financial Conduct Authority and Bank of England, with additional oversight in the US and EU.

Frequently asked questions
Who runs investment decisions at London Stock Exchange Group?
CEO David Schwimmer, appointed in 2018, leads strategy and operations for the group. He previously served as COO at the New York Stock Exchange and held senior roles at Goldman Sachs. LSEG's board includes Chair Don Robert and CFO Anna Manz, among others.
How does LSEG generate revenue?
LSEG generates revenue from three primary segments: capital markets (trading fees and listings on its exchanges), post-trade services (clearing, settlement and other risk management via LCH and Monte Titoli), and data & analytics (Refinitiv data terminals, FTSE Russell indices and financial benchmarks). The data & analytics segment now contributes the largest share of group revenue.
Is LSEG structured as an exchange or an asset manager?
LSEG is a publicly traded exchange operator and financial infrastructure provider, not a traditional asset manager. However, its FTSE Russell index division manages over $15 trillion in benchmarked assets, and the group's private markets unit facilitates capital formation comparable to asset management functions.
What is LSEG's relationship with Microsoft?
In 2022, LSEG and Microsoft announced a 10-year strategic partnership in which Microsoft acquired a 4% equity stake in LSEG via the Refinitiv deal. The partnership involves migrating LSEG's data and analytics onto Microsoft's Azure cloud, integrating AI tools for financial workflows, and co-developing next-generation data products for institutional clients.
Does LSEG invest directly in companies?
LSEG's investment is primarily infrastructural: it owns exchanges (LSE, Borsa Italiana), clearing houses, data terminals, and index businesses rather than taking equity positions in operating companies. It does operate a dedicated private markets unit (LSEG Private Markets) that connects investors with private companies, but this is a platform business, not a direct investment vehicle.
What is LSEG's role in index and benchmark administration?
FTSE Russell, LSEG's index subsidiary, administers over 15,000 indices used by pension funds, sovereign wealth funds, and ETFs. It is a major provider of equity, fixed income, real estate, and multi-asset benchmarks, regulated by the UK Financial Conduct Authority under the EU Benchmark Regulation for key indices like the FTSE 100.
How did the Refinitiv acquisition change LSEG?
Completed in 2021 for $27B, the Refinitiv acquisition transformed LSEG from an exchange operator with a domestic focus into a global financial data and analytics powerhouse. It added Refinitiv's Eikon desktop terminals, FXall currency trading platform, and a vast portfolio of fixed income and pricing data — making LSEG a direct competitor to Bloomberg in the data terminal market.
