Goldman Sachs limits AI coding tools like Claude Code to engineers
Bloomberg reported on November 2 that Goldman Sachs has barred most staff from using advanced AI coding tools after a review of productivity and risk. Under internal guidance updated in October and seen by Bloomberg, Anthropic's Claude Code and Microsoft's GitHub are now limited to the bank's engineers. Bankers had been allowed to use both tools for work for several months before the change. Bloomberg's account puts the engineering group at about 12,000 people.
Traders had used the tools to monitor client trading flows, model market changes and produce written and graphic material, according to a person familiar with the matter cited by Bloomberg, and some have objected to the limit. Bloomberg's reporting does not say how many employees are affected. The directive does not cover strats, a hybrid group that combines software engineering, quantitative research and trading. Spokesperson Nick Carcaterra said the bank makes certain AI tools available to determine the best use cases across the firm, and The Decoder reported that he described the experimentation phase as over.
The reversal follows a more open stance. In July, Chief Information Officer Marco Argenti praised 'vibe coding' by non-technical staff, who built prototypes and handed them to engineers to scale. Earlier in 2026, Goldman also restricted Anthropic's Claude for its Hong Kong staff, a limit tied to location, while the new change is based on job role. Other AI systems, including Google's Gemini and OpenAI's ChatGPT, remained available, according to Your News.
Why it matters
For companies selling coding agents into large enterprises, the case shows that buyers may decide access by job role rather than by a single company-wide license. That matters for seat-based pricing, because a purchase approved for a whole firm may end up used by a much narrower group. Usage forecasts should model engineering-only populations, and vendors should expect procurement teams to ask for role-based permissions, admin controls and audit logs before access widens beyond developers.
For investors, the episode is a signal that productivity claims for agent tools will face risk review at the largest banks, and that adoption among non-technical staff can be reversed by internal policy. Startups that sell into finance should be ready to show who can use a tool, what systems it can touch, and who owns the output, since those questions now come before any expansion of seats.
