From spreadsheets to live market data, Anthropic’s LLM Claude is becoming the default copilot for finance professionals. Anthropic is doubling down on its lead in financial AI with updates that make Claude the most integrated LLM in financial services — spanning Excel modeling, real-time market data, and automated financial analysis.
The latest release introduces:
- Claude for Excel
- New connectors to leading financial data providers
- Pre-built Agent Skills for core analytical workflows, including discounted cash flow (DCF) modeling, due diligence, and earnings analysis
Together, these updates embed Claude directly into the daily tools and data pipelines used by bankers, analysts, and portfolio managers.
Claude for Excel: A New Analyst in the Spreadsheet
Now in beta for Enterprise, Teams, and Max users, Claude for Excel brings the model directly into Microsoft Excel via a sidebar that can:
- Explain how a spreadsheet works and highlight dependencies
- Debug and fix formulas
- Populate templates with new data and assumptions
- Build complete financial models from scratch
Every action is transparent and traceable — Claude shows which cells it changed and why, turning Excel into a live, auditable AI workspace.
This integration builds on Anthropic’s broader Microsoft partnership, allowing Claude to interact with files, emails, and Teams conversations through Microsoft 365 and Copilot Studio.
Connecting to Real-Time Market Intelligence
Anthropic is expanding Claude’s connectors to give the model governed access to live financial data across multiple sources, including:
- LSEG: equities, fixed income, FX, and macro indicators
- Moody’s: credit ratings, ownership data, and company financials
- Aiera: real-time earnings call transcripts and investor events
- Third Bridge & Chronograph: expert interviews and private-equity performance data
- MT Newswires: multi-asset market coverage
- Egnyte: secure search across internal investment documents and data rooms
These connectors transform Claude into a real-time financial analyst, capable of blending internal and external data for valuation, research, and compliance, without breaching governance rules.
Pre-Built Agent Skills for Financial Workflows
Anthropic has released six new Agent Skills to accelerate adoption in finance:
- Comparable company analysis with refreshable valuation multiples
- Discounted cash flow (DCF) models with scenario toggles and sensitivities
- Due-diligence data packs that extract structured insights from data rooms
- Company teasers and pitch-book profiles
- Earnings analysis from transcripts and financial reports
- Initiating coverage reports combining industry overviews and valuation frameworks
These skills run across Claude.ai, Claude Code, and API environments, enabling deployment across research, corporate finance, and investment processes.
Claude: The Emerging LLM Standard for Finance
Claude’s trajectory in financial services focuses on deep vertical integration rather than generic AI capability. By combining Sonnet 4.5’s top-ranked performance on the Finance Agent benchmark (55.3% accuracy per Vals AI) with the workflows analysts actually use — Excel, FactSet, LSEG, Moody’s, Morningstar — Anthropic is positioning Claude as the go-to institutional AI layer for the financial sector.
Banks, asset managers, and insurers are already using Claude across:
- Front office: client engagement, underwriting
- Middle office: risk, compliance
- Back office: code modernization, reporting
The new suite of financial features turns Claude from a text model into an end-to-end financial workbench.
As other AI models chase general intelligence, Anthropic’s focus on governed, auditable, and domain-specific AI is making Claude the default choice for serious financial work.
