Fixing Technical Debt is the Fastest Route to AI-Ready Market Data

Modernising market data systems is becoming a quiet prerequisite for AI ambitions. AI isn’t something you can just ‘switch on’ and expect it to work without strong data foundations, but many firms are still running legacy market data environments where fragility hides in plain sight, and the stack simply wasn’t built for AI. Opaque middleware, manual entitlements, brittle integrations, and siloed tooling held together by “tribal knowledge + spreadsheets.” With resilience now auditable under regulations like DORA and tighter FCA expectations, those gaps aren’t just inconvenient; they compound into operational and regulatory risk. Modernisation isn’t simply “swapping a vendor” or “adding the cloud”; it’s an operating model upgrade built to be observable, automated, governed by design, cloud-ready where it fits, and justified on ROI, meaning fewer incidents, faster change, and lower overhead, not short-term TCO.
