Claude for Investing: What It Can Do (2026)

Federico Kunze Küllmer is the founder of Moneda, one of the tools compared here.

Short answer: Claude is a general AI assistant from Anthropic. It is good at reading long documents, explaining finance terms, comparing companies and working through numbers you give it. On its own it does not know your portfolio and cannot place trades. The Free plan includes web search; Pro costs $20 a month billed monthly ($17 a month billed annually) and adds Research; Max starts at $100 a month. To use Claude on your real holdings, connect it to an investing account through a connector, such as Moneda MCP, and keep every trade approval in your own hands.

What Claude is, in one paragraph

Claude is a chat assistant. You type a question, it answers. For investing, that means it can act like a patient study partner: it reads an annual report with you, explains what a ratio means, and lays out the case for and against a company. What it gives you is analysis. The decision stays with you, and so does the job of checking the numbers.

What Claude can do for investors

1. Read and summarise company filings

A 10-K is the annual report a US-listed company files with the SEC, the US market regulator. It runs to a hundred pages or more. Upload one, or ask Claude to find it with web search, and it will pull out what matters.

Questions to try:

• "Summarise the risk factors in this 10-K in plain English. Which three are new this year?"
• "How did revenue and operating margin change over the last three years? Show the figures from the filing."
• "What does management say about debt, and when does the biggest loan come due?"

2. Explain finance terms without talking down to you

Claude is patient with basic questions. Good ones to start with:

• P/E ratio (price to earnings): the share price divided by yearly profit per share. A P/E of 20 means you pay 20 dollars for each dollar of yearly profit.
• Free cash flow: the cash a business has left after paying for its operations and investments. It is harder to dress up than reported profit.
• ETF (exchange-traded fund): a fund that holds many stocks or bonds and trades on an exchange like a single share.
• DCF (discounted cash flow): a way to value a company by estimating its future cash and translating it into today's money.
• Moat: a lasting advantage, like a strong brand or network, that keeps competitors away.

Ask: "Explain free cash flow with a coffee shop example, then show me where to find it in Apple's cash flow statement."

3. Compare companies and build a simple valuation

Give Claude two companies and ask for a side by side. It can also set up a basic DCF if you supply the inputs, and Free, Pro and Max all include code execution for creating files, so it can produce a spreadsheet.

• "Compare Costco and Walmart on revenue growth, margins and debt. Put it in a table and say where each number comes from."
• "Build a simple DCF for this company using 6% growth for five years and a 9% discount rate. Then show me how the value changes if growth is 3%."

The model is only as good as the assumptions. Change them and watch how much the answer moves. That alone teaches you a lot about valuation.

4. Argue both sides

One of the most useful habits: ask for the bear case on something you already like.

• "I'm bullish on this stock. Give me the strongest case against it."
• "What would have to go wrong for this company's profit to halve in two years?"

5. Go deeper with Research

On Pro and Max, Claude's Research feature runs a longer search across many sources and writes up what it finds. It works well for a first look at an industry, say "How do the big US railroads make money, and what has changed since 2020?" Treat the output as a reading list with notes attached, not a verdict.

What Claude cannot do on its own

• It does not see your portfolio. Unless you paste your holdings in or connect an account, Claude knows nothing about what you own.
• It cannot trade. Plain chat has no access to a brokerage.
• Its numbers can be wrong. Language models sometimes misread a table or state a figure with confidence it has not earned. Ask for the source of every number.
• It is not personal financial advice. Claude does not know your taxes, your timeline or how much risk you can stomach unless you tell it, and even then it is a general tool.

Connecting Claude to your investing account

Claude supports connectors, which let it talk to other apps and tools. This is where it gets practical for investors. Through a connector, Claude can read your real holdings instead of a pasted list.

Moneda is one example. Moneda MCP connects Claude (and ChatGPT) to your Moneda account with the permissions you set. You choose what each agent can see and do. Payments are approved in the Moneda app, so Claude can prepare something but cannot push money out on its own. On Premium and Ultra there is also a REST API and a CLI (command line tool) for people who want to script things.

Once connected, you can ask things like:

• "Which of my holdings had the worst month, and why?"
• "How concentrated is my portfolio in tech?"
• "Compare my portfolio's return this year against gold."

Before you connect any account, check three things:

1. What the agent can read, and whether you can limit it.
2. Whether it can move money, and who approves each move.
3. How to revoke access later.

Claude vs a dedicated investing agent

Claude is a generalist. A dedicated investing agent is built around market data and runs inside the account where you invest. Here is how they compare on what each vendor publishes:

Where Moneda AI fits

Moneda AI runs on Numa 1, Moneda's financial AI engine. It researches stocks, ETFs, crypto and a few commodities (gold, silver and oil, through ETFs), working from company filings and live market data. It works each figure out from the data and shows the source behind it. A few things it does that a general assistant does not do out of the box:

• Gives the bull and the bear case.
• Scores a company on its 7 Powers, a framework for spotting a moat.
• Checks quality of earnings, meaning whether reported profit is backed by real cash.
• Shows the Moneda Ratio, a descriptive 1 to 7 scorecard.
• Sends daily briefings on your portfolio and the market, and summarises each company's earnings.
• Searches SEC filings and earnings-call transcripts by ticker and quarter.
• Screens for stocks from a plain description, like "profitable US companies that sell to hospitals."
• Builds an illustrative portfolio from your goal, tracks it, and tells you when something changes.
• Stress-tests a portfolio against 2008, 2020 and 2022, and benchmarks it against gold, an index or any fund.

In the same app you can invest in US-listed shares and ETFs (fractional) and crypto. The agent never tells you to buy or sell. You approve each trade yourself with your passkey, using your face or fingerprint.

On results: in Moneda's own tests in October 2026, Moneda AI scored 97.9% on groundedness, 92% on claim verifiability, 95.6% on FLARE-CFA and 80% on the public set of the Vals AI Finance Agent Benchmark v2. Moneda ran and graded that last one. Vals AI's top published score is 65.4%, but that is on its private set, a different set, so the two numbers are not directly comparable.

Honest limit: you can invest in US-listed shares and ETFs only, so no European-listed stocks or funds. Moneda is a mobile app with a web version, built in Europe.

A reasonable setup for many people: use Claude for wide reading and learning, and an investing agent for questions about your own money. With Moneda MCP you can do both from Claude.

What to verify yourself

Whatever AI you use, check these before acting:

1. Every number that matters. Open the filing and find the figure. If the AI cannot point to a source, do not rely on it.
2. The date of the data. Prices and results go stale fast. Ask "What date is this figure from?"
3. The assumptions in any valuation. Growth rate, discount rate, margins. Small changes swing the answer.
4. Fees and taxes. Ask your provider directly and read their price page.
5. Whether it fits you. Your goals, timeline and other savings matter more than any single stock.

A simple workflow to start

1. Pick one company you already know as a customer.
2. Ask Claude to summarise its latest 10-K in ten bullet points.
3. Ask for the bull case and the bear case.
4. Ask what three numbers you should watch each quarter.
5. Check those three numbers in the filing yourself.
6. If you invest, write down why in one sentence, so you can judge later whether the reason still holds.
