Opetek Launches ARIUS AI Platform for Institutional Trading Desks

London-based Opetek, incorporated on Nov. 28, 2022, develops quantitative reasoning systems for financial markets and previously raised £500,000 in pre-seed funding. Its proprietary ARIUS platform is aimed at institutional trading desks, where AI must do more than generate text: users require quantitative analysis, reproducible results and the ability to interpret macroeconomic developments alongside large, fast-moving market datasets.

Opetek has unveiled ARIUS, short for Artificial Realtime Intelligent Unified System, as an AI platform for institutional trading and market analysis. The company said on May 14, 2026, that ARIUS was live in a pilot with an unidentified tier-one bank across multiple trading time zones. Opetek plans to develop the system with market participants and broaden deployments, but has not disclosed pricing, contract value or a timetable for general commercial availability.
