We demonstrate the Smart Marketplace for 6G Ser vices, a marketplace-based framework for federating heteroge neous service and infrastructure providers. The demo showcases an end-to-end procurement workflow in which users submit intent-based service requests, providers expose capabilities, and the marketplace composes feasible multi-provider service bun dles. The system integrates service negotiation and dynamic price estimation for complex 6G service demands. These components enable secure and coordinated resource procurement across multiple administrative domains.
