Chatham Financial says a trade validation application built with OpenAI's Codex reduced review time from approximately 30 minutes to under four in early measurements. OpenAI published the customer case study on October 2.

The application assembles transaction evidence, checks key terms and flags discrepancies for the capital markets advisory firm's reviewers. Chatham is comparing its results with real transactions and experienced reviewers before expanding automation. It plans to extend the application to additional trade types while retaining professional oversight.
