LSEG Accelerates Tick History Analysis with NVIDIA

· Issued by London Stock Exchange Group PLC

Summary by 6ix

London Stock Exchange Group PLC (LSEG) is collaborating with NVIDIA so financial institutions can analyse large volumes of LSEG Tick History historical market data faster using NVIDIA cuDF, software for data processing on NVIDIA GPUs (graphics processors used for accelerated computing). LSEG says this works without creating another full copy of the data and keeps licences, permissions and controls in place.

Key details

  • LSEG says benchmark analysis shows years of Tick History data can be analysed in seconds using NVIDIA cuDF and Polars, reducing processing time from hours to seconds.
  • LSEG Tick History holds 110 trillion rows of data across 100 million instruments, spanning more than 30 years and more than 580 exchanges, trading venues and contributors.
  • In H1 2026 (the first half of 2026), traffic over LSEG's real-time network grew by 29% versus H1 2025, reaching a peak of 26 million messages per second in June, while customer API requests for Tick History data increased by 48%.
  • The collaboration is part of LSEG's Everywhere AI strategy and is intended to support uses including quantitative research and strategy testing, execution and market analysis, and risk, market replay and AI-enabled research.

LSEG significantly accelerates analysis of years of Tick History market data with NVIDIA cuDF

●         Benchmark analysis shows years of LSEG Tick History can be analysed in seconds using NVIDIA cuDF for GPU-accelerated data processing, reducing processing time from hours to seconds.

●         Enables firms to bring deeper historical analysis closer to decision-making as markets move towards near 24-hour trading

LSEG today announced a collaboration with NVIDIA to help financial institutions analyse large volumes of LSEG Tick History data at significantly greater speed and scale using NVIDIA cuDF for accelerated computing on NVIDIA GPUs. This is achieved without creating another full copy of the underlying dataset while also preserving the licences, permissions and controls that govern access.

The collaboration brings LSEG’s trusted, permissioned historical market data closer to the computing environments used for quantitative research, market analysis and AI. As part of the LSEG Everywhere AI strategy, users can run large-scale data processing on Tick History datasets to turn LSEG content into insights faster.

Benchmark analysis shows years of LSEG Tick History can be analysed in seconds using NVIDIA cuDF and Polars, reducing processing time from hours to seconds. As equity trading moves towards near 24-hour operation, firms are moving away from legacy models that rely on market-close data loading and overnight analytics. This capability enables deeper, continuous historical analysis throughout the trading day.

LSEG Tick History holds 110 trillion rows of data across 100 million instruments spanning more than 30 years and more than 580 exchanges, trading venues and contributors. In H1 2026, traffic over LSEG’s real-time network grew by 29% versus H1 2025, reaching a new peak of 26 million messages per second in June, while customer API requests for Tick History data increased by 48%.

Ron Lefferts, Co-Head of Data & Analytics, LSEG, said:

“This collaboration expands how customers can draw insight from LSEG’s trusted, governed Tick History. Customers want to work with detailed historical data at speed, without the burden and risk of creating another full copy. This helps firms analyse deeper histories closer to the point of decision, while keeping the permissions and controls they rely on fully intact.”

Ioana Boier, NVIDIA, said:

“AI is opening new ways to understand market behavior across vast amounts of data. NVIDIA cuDF helps researchers analyze LSEG Tick History at scale without downsampling away the detail that makes the data valuable for advanced analytics and AI.”

The collaboration is intended to support customer workflows including:

●         Quantitative research and strategy testing: examining longer histories, additional trading venues and a wider range of market conditions without reducing the detail of the underlying data.

●         Execution and market analysis: reconstructing order books and historical market conditions, and analysing pricing, liquidity and execution quality at greater depth.

●         Risk, market replay and AI-enabled research: accelerating scenario analysis and historical market replay, and creating a foundation for customers to apply their own analytical and AI models to governed LSEG data.
