Looking Good, Billy Ray!

“Looking good, Billy Ray.” “Feeling good, Louis.”

That is the closing exchange of Trading Places (1983), delivered between two reformed traders on a beach

after they cleaned out the Duke brothers in orange juice futures. The whole movie hinges on a question Wall Street has been quietly answering for forty years: who gets the pit pass?

Who would have thought a movie from 1983 would be relevant in today's world.

Earlier this year, Goldman Sachs answered it again. Adding to this, earlier in May, Anthropic rolled out new Claude Financial Agents.

The bank is now running autonomous Claude agents inside trade accounting and client onboarding. The first major US bank to give a large language model real operational scope inside core finance operations.

This is not a demo, it is a structural shift from AI as assistant to AI as transactional authority.

In Trading Places, Mortimer and Randolph Duke hand the pit pass to Billy Ray Valentine because

they bet nature loses to nurture. Goldman is making a similar bet. That an AI agent with the right scaffolding can do work the desk used to do.

For CPA firms watching this, the right question is not whether to be excited or scared. It is the question Mortimer Duke should have asked before he handed over the pit pass: what controls did we put in place?

COSO’s 2026 Achieving Effective Internal Control Over Generative AI guidance is built on exactly this scenario. AI agents inside core finance operations are not a tooling decision. They are an internal-controls decision. They demand the same five-component framework as any other actor in a book-and-record-of-transaction workflow.

What changes for advisory practice this quarter: every client managing partner asking “should we automate something with AI?” is now asking the wrong question. The right one is, “What is our control framework when AI starts making transactions on our behalf?”

The firms that have an answer by fall will win the work. The firms still pitching “AI for productivity” will not.

The Dukes made a bet they could not control. Louis and Billy Ray made a better one. And the Dukes was built on inside information they actually understood!

What is your firm’s bet, and how would you describe its controls to a client audit committee when called upon?
