See your investment holdings in Claude or ChatGPT

Yes, you can see your investment holdings in Claude or ChatGPT today. Connect your brokerage accounts to Era and your assistant reads what you actually own: every position with its quantity and cost basis, the tax lots behind it, how it changed over time, and where your portfolio sits in your wider financial health. You ask in plain English and get an answer drawn from your own numbers.

That is more than a balance. A balance tells you what an account is worth today, while holdings tell you what is inside it, what you paid for it and what you did with it along the way.

Can Claude or ChatGPT see my investment holdings?

They can once Era sits between them and your brokers. Era connects your brokerage, retirement and bank accounts in one place, then offers the same view to every assistant you use, so Claude, ChatGPT and Gemini all read the same positions, the same cost basis and the same history without you pasting a single figure into a chat.

Claude Personal Finance, which Anthropic launched on 5 November 2026, shows investment accounts as balances and credit limits only, "not holdings, trades, rates, or terms" (support.claude.com, 2026-11-05). Era picks up where that stops. It reads the holdings themselves, and it does so inside Claude, ChatGPT or whichever assistant you prefer.

What can my assistant tell me about each position?

Ask about any position and your assistant answers from the record: how many shares you hold, the average price you paid, your total cost basis, the current value and the gain or loss that follows. Because Era keeps this for every account you connect, you can ask about one stock, one fund or the whole portfolio.

Some questions people ask once their holdings are connected:

• "What is my cost basis in Apple across all my accounts?"
• "Which of my positions is furthest from what I paid for it?"
• "How much of my portfolio sits in my three biggest holdings?"
• "What would my gain be on the oldest shares I own?"

What are tax lots, and can my assistant read them?

A tax lot is one purchase of a security: the date you bought it, how many shares and the price you paid. When you buy the same stock in March and in September, you hold two lots, each with its own cost basis and holding period. Era keeps your lots, so your assistant can show every purchase behind a position.

That matters whenever you want to know what a sale would look like, because the answer depends on which shares you sold. Ask Claude to list your lots for a stock, oldest first, and it can tell you what each one cost and how long you have held it.

How has a position changed over time?

Era records how each position moved: when you bought, when you sold and how the number of shares and their value changed along the way. Ask your assistant how your holding in a fund has grown since last year, and it can describe both the shares you added and the value they were worth at each point.

This turns a vague feeling, such as "I think I've been adding to this one for ages", into a clear history. It also means you can ask Claude to set your portfolio's value over time beside your savings, so you see the whole of your money moving together.

Can I see the same stock across all my accounts?

Yes. Many people hold the same fund in a brokerage account, an IRA and a 401(k), and each account lists it separately. Era rolls the same security up across accounts, so your assistant can tell you how much of it you own in total, what you paid on average and which account holds the most.

You can also group holdings yourself, for example putting several index funds into one group called "core", and ask about the group as one position. The grouping you set in Era is the grouping every assistant uses.

Where does my portfolio sit in my financial health?

Your investments are one part of a bigger picture, and Era shows them that way. Your financial health in Era draws on your cash, debts, spending and investments together, with the figures and analysis behind them, so an assistant answering a question about your portfolio can also see whether your emergency fund is in order.

That is the difference between a portfolio tracker and an assistant that knows your finances. Ask whether you are ready to put more into investments this month, and the answer starts from your real accounts rather than a generic rule of thumb.

Which brokers can I connect to Era?

Era connects investment accounts from brokers such as Charles Schwab, Fidelity, Robinhood, Interactive Brokers and Vanguard, alongside your banks and credit cards, so your portfolio and your cash sit in the same conversation. Era connects accounts across the US, the UK, Canada, France, Germany, Spain, and 40+ countries in all.

If your broker is not on the list, bring in its statements. Upload a brokerage statement to your Document Library and Era reads it, pointing every value back to the page and snippet it came from, and its transactions can be imported straight into a manual account. You can keep your holdings up to date either way.

Set it up in four steps

1. Create a free account at era.app.
2. Connect your brokerage accounts from the list, signing in inside your broker's own screen.
3. Add Era to Claude or ChatGPT as an MCP server, and approve the consent screen.
4. Ask a real question, such as "what is my cost basis in my biggest holding?"

The step-by-step guides are in how to connect Claude to your bank account and how to connect ChatGPT to your bank account; the connection is the same for your brokers, and one connection serves both assistants.
