Supporting lit markets with resilient, purpose-built infrastructure
Lit markets drive efficiency — we help them stay that way.
Exchange Support Services
McKay Brothers supports the world’s leading price discovery venues — public lit markets — with infrastructure engineered for resilience, transparency, and speed.
Our services help exchanges extend their reach, reduce systemic risk, and serve market participants with precision engineered connectivity, grounded in real-world performance constraints — physical and policy-based.
We believe efficient, accessible lit markets are the foundation of fair price discovery. By delivering deterministic, equal-access transport solutions to and from exchange venues, we help maintain the integrity and performance of these systems under real-world load.
