## Summary

Schwab announced a partnership to embed Anthropic’s Claude assistant across its custodian network, which serves more than 16,000 registered investment advisors. The agreement includes a clause that forbids Anthropic from retaining any conversation input or output for future model training. Schwab’s head of AI for Advisor Services, Alison Dooher, said the firm specifically required that no data be kept, and that client account numbers will be masked while social security numbers and dates of birth are not passed to Anthropic.

Anthropic’s enterprise‑level Claude plan already defaults to a no‑training policy, and the Schwab deal extends that restriction to all Claude subscriptions used by Schwab advisors, even those on lower‑tier licenses. The integration is read‑only, meaning advisors cannot edit data returned by the chatbot. Dooher described the rollout as a “walk before run” approach, with future possibilities for more automated workflows once governance standards are met. Other firms joining the Claude plugin ecosystem include Vanguard, BlackRock, Addepar, Envestnet, iCapital, Orion, Wealthbox, Wealth.com and Zocks.

## Key points

- Schwab’s Claude integration covers over 16,000 RIAs and bans Anthropic from retaining any conversation data for model training.
- Account numbers are masked and SSNs or dates of birth are not shared with Anthropic under the agreement.
- The no‑training provision, standard for Anthropic’s enterprise plan, is extended to all Claude licenses used by Schwab advisors.

## Why it matters

The deal sets a precedent for data‑privacy clauses in enterprise AI contracts, influencing how custodians and other regulated firms adopt generative AI.
