BMLL, SIGMA AI Team Up on Real-Time Execution Intelligence

BMLL supplies harmonised historical Level 1, 2 and 3 order-book data on a T+1 basis, while SIGMA AI uses agentic artificial intelligence to turn live market inputs into readable analysis and trading signals. Linking those capabilities matters because banks, brokers and asset managers have typically separated historical research and post-trade measurement from intraday decision-making. A common intelligence layer could help users compare current conditions with granular market history and strengthen execution, risk and research workflows.

BMLL and SIGMA AI announced the partnership on July 22, 2026, saying they would combine BMLL’s harmonised historical datasets, covering more than 140 trading venues, with SIGMA AI’s real-time intelligence and analytics. The companies aim to create a real-time execution-intelligence layer for global capital markets, extending analysis from post-trade review toward pre-trade and intraday use. They did not disclose financial terms, named customers or a firm timetable for commercial rollout.
