London Stock Exchange Owner Says NVIDIA Chips Crunch Years of Trading Data in Seconds

London Stock Exchange Group (LSEG) said today (Wednesday) that years of its Tick History data can be analyzed in seconds on NVIDIA chips, down from hours. The figure comes from a benchmark that used NVIDIA's cuDF software with the Polars data library.

Tick History holds 110 trillion rows on 100 million instruments from more than 580 exchanges, venues and contributors, going back over 30 years. Under the setup, LSEG said, customers can run it on NVIDIA graphics processors without making another full copy, and existing licenses and access controls stay in place.

The work is part of LSEG Everywhere, the group's strategy for delivering data into AI tools, which in December connected its feeds to ChatGPT for licensed users.

Use of the archive is growing. Customer API requests for Tick History rose 48% in the first half from a year earlier, while traffic on LSEG's real-time network grew 29% and peaked at 26 million messages per second in June. LSEG gave no launch date or pricing for the GPU setup.

What Changes for Brokers and Trading Desks

Firms want historical data "without the burden and risk of creating another full copy," said Ron Lefferts, who has co-led LSEG's Data & Analytics division since April 2025.

Execution-quality checks are part of how brokers show regulators they deliver best execution. LSEG already sells them cross-venue surveillance built on a consolidated orderbook of more than 40 UK and EU venues, launched in January.

Retail brokers already buy LSEG content. Capital.com signed up for LSEG news, market data and research feeds in February 2025 to serve more than 750,000 traders.

Researchers can work "without downsampling away the detail that makes the data valuable," said Ioana Boier, global head of capital markets strategy at NVIDIA. Downsampling means cutting tick data into coarser intervals to make it easier to process.

Exchanges and Data Vendors Court the Same Users

Data & Analytics, the division that sells Tick History, grew 5.1% on an organic basis in the first half, the slowest of LSEG's four divisions. Markets grew 11.9% and Risk Intelligence 9.7% on the same basis.

KX, the time-series database company that merged with tick data provider OneTick in 2025, released two AI blueprints built with NVIDIA in March, including a trading signal agent.
