Claude: useful but limited
Threads show Claude can build basic financial models and integrate with Excel via prompt templates, and there are collections of 15 prompts that replicate Wall‑Street tools (backtesting, risk management, ML models) — yet human oversight is still required for complex, production‑grade work. Enthusiasts are packaging prompt libraries to reproduce workflows valued at six‑figures. (x.com) (x.com)
Anthropic’s product announcements show Claude gained a native Excel add‑in and market‑data connectors as part of an Oct 27, 2025 “Claude for Financial Services” expansion that explicitly lists pre‑built skills such as DCF and portfolio analytics. (anthropic.com) FinPrompter markets “The Wall Street Prompt Library,” advertising hundreds of prompts across investment research, due diligence, portfolio monitoring and financial modeling with team vaults and “smart chaining” to link multi‑step workflows. (finprompter.com) Open‑source hubs show community consolidation: the “Awesome Claude Prompts” GitHub repo has roughly 4.6k stars and community curation, while “TheBigPromptLibrary” repository lists thousands of prompt entries and thousands of stars/forks. (github.com) Curated commercial packs quantify scale: “Claude in Excel” publishes a library of 50+ ready‑to‑use templates, PromptLeo hosts 100+ investor prompts, and ThePromptLibrary groups 30+ finance‑focused prompt templates. (claudeinexcel.com) Multiple marketplaces enable sales and subscriptions—ThePromptz, PromptBase and PromptFairs list finance prompt listings and creator storefronts—while a Forbes guide documented how AI prompt workflows have been turned into scalable, six‑figure freelance businesses. (thepromptz.com) Hands‑on writeups and guides report operational gains: an industry blog described using Claude’s Excel plugin to debug multi‑sheet LBO models and claimed up to a 5x productivity boost, and product documentation shows Claude can ingest deal documents and generate working.xlsx models for scenario analysis.
