Goldman Sachs limits Claude Code and GitHub tools to its engineers, Bloomberg reports
Bloomberg reports Goldman Sachs restricted Claude Code and GitHub tools to engineers. Most bankers and traders lost access; the risks were not detailed.
Goldman Sachs has barred most of its bankers and traders from using advanced AI coding tools, Bloomberg reported on November 2, 2026. The tools named are Anthropic's Claude Code and GitHub's, and internal guidance updated in October limits them to engineers. The reports we read describe no triggering incident.
The essentials
- What changes: most bankers and traders lose access to Claude Code and GitHub tools, after a review of productivity and risk.
- Who keeps access: engineers, and, according to a second anonymous source, the "strats".
- What Goldman says: a spokesperson cites productivity and risk management; no written statement was found.
- Not specified: the precise risks, the effective date and the number of people affected.
What does Bloomberg report?
According to Bloomberg (Todd Gillespie, November 2, 2026), Goldman Sachs prohibited most of its bankers and traders from using advanced AI coding tools after reviewing productivity and risks. The tools named are Anthropic's Claude Code and Microsoft's GitHub. Bloomberg writes "GitHub"; some reprints say "GitHub Copilot". Use is now limited to engineers, per internal guidance updated in October and seen by Bloomberg. Bankers had been able to use these tools for months. We read it through two reprints, not the original.
Who keeps access, and who loses it?
The "strats", staff at the interface of trading, quantitative research and software engineering, are exempt, per a second anonymous source cited by Bloomberg. Bloomberg gives 12,000 engineers at Goldman, in the passage about chief information officer Marco Argenti. It gives neither the total headcount nor the number of bankers and traders affected ("most").

What does Goldman say, and why?
Spokesperson Nick Carcaterra, per Bloomberg, said the bank makes certain AI tools available to determine the best uses across parts of the firm. The bank assesses a variety of factors, including productivity and risk management, after a period of experimentation, and puts the tools in the hands of those "best suited to leverage them for the long term". According to an anonymous source, some traders are frustrated; they used the tools to follow client flows, model markets and positions, and produce written and graphic content. We found no written Goldman statement and no comment from Anthropic, GitHub or Microsoft.
How does this fit into recent months?
In July 2026, per Bloomberg, Argenti had praised the "vibe coding" of non-technical staff such as traders and bankers, whose creations engineers then improved.

Separately, Bloomberg notes that earlier in 2026 Goldman restricted the use of Claude for its Hong Kong staff. That restriction is location-based and distinct; it is not shown to be linked.
What is not established?
The specific risks targeted; the exact effective date; the number of people affected; whether tools other than Claude Code and GitHub are covered; whether Goldman's internal AI assistant is concerned; the number or exact definition of "strats"; why access is split this way; any comment from Anthropic, GitHub or Microsoft.
