Chatham Financial Cuts Trade Validation to Under 4 Minutes With OpenAI Codex and GPT-5.6

Summary
Chatham said an OpenAI-built trade validation application cut review time from about 30 minutes to under 4 minutes, with results still being checked against real transactions and experienced reviewers.
Codex gathers transaction evidence, compares key terms and flags discrepancies, fitting Chatham’s push to turn capital-markets processes into governed, auditable workflows rather than simply speeding every task.
GPT-5.6 now powers AI features across employee-built apps, client workflows and Chatham Onyx, the firm’s operating system for connected assets, debt and derivatives data.
Onyx uses multiple OpenAI models for different cost and accuracy needs, while tools such as ChatFIN summarize market patterns, analyze portfolios and link users to legal documents.
Chatham plans to extend trade validation to more products and automate more workflow steps, aiming to free advisors from routine assembly work so they can focus on judgment-heavy client advice.
