Announcement: Crushing Fraud Chili Cook-Off Competition

CMS is announcing the Crushing Fraud Chili Cook-Off Competition, a market-based research challenge aimed at harnessing explainable artificial intelligence, specifically machine learning models, to detect anomalies and trends in Medicare claims data that can be translated into novel indicators of fraud. This challenge also seeks scalable analytic and policy solutions designed to target and address these high-risk areas within the Medicare program. 

The Chili Cook-Off kicks off on August 19, 2025. CMS invites research proposals from all interested parties. See here for further information about the challenge or to submit your proposal.
