Smarkets runs one of the world’s most sophisticated prediction markets, handling over £29 billion in volume since 2010 and engaging 200,000+ traders globally. We’re a technology company that happens to revolutionise betting - from sports to political markets, to delivering the sharpest prices and the fairest odds.
Our stack is designed for scale, reliability, and speed: Linux, Kafka, Postgres, Kubernetes, with Python 3, C++17, and React powering our platform. We build infrastructure that institutions trust while keeping trading accessible to everyone. Our edge? We’ve thrived through every market cycle, competitor, and industry revolution.
At the heart of our success are our people. We create a high-performance environment where exceptional talent can thrive, blending deep business experience with a commercial mindset to drive strategic growth.
If you’re ready to help shape the future of prediction markets with cutting-edge technology and a customer-first philosophy, Smarkets is where you belong.
