FOURWEEKMBA EXPLAINER · FROM THE NEWSROOM · UPDATED 12 NOVEMBER 2026
The short answer: today the AI assistants from Anthropic and OpenAI earn from personal finance in one way: the user’s subscription. Older finance apps mostly get paid by someone else: lenders paying referral fees, card swipes paying interchange, banks paying for customers’ cash, or a yearly fee on invested assets. Under all of them sits a data layer that the app pays for, not the user.
Free to share with a link to this page. Figures from each company’s latest 10-K: Robinhood and Chime for 2025, Wealthfront for the year to 31 January 2026. Shares are our arithmetic. Wealthfront’s other revenue (0.4%) is too small to label.
A personal finance assistant reads your accounts and answers questions about your money. The business question is simple: who pays for that? There are two broad answers.
The user pays. A monthly subscription, or a fee on the money you let the service invest. The service earns the same whatever you decide.
Someone else pays. A lender pays when you take its loan. A card network pays a fee each time you swipe. A bank pays for the cash the app sends its way. Here the service earns more when you act in a certain way. That is not wrong in itself, but it changes what the service is paid to want. For the general idea, see our guide to revenue models and to the fintech business model.
How the AI assistants charge today: subscription only
Claude. Anthropic launched Personal Finance in Claude on 5 November 2026, as a US beta on its Pro, Max and Ultra plans. Claude’s pricing page lists Pro at $17 a month with the annual discount ($200 billed up front), or $20 billed monthly; Max at $100 a month; Ultra at $200 a month. The announcement is direct about the other routes: “Like the rest of Claude, Personal Finance has no ads or sponsored recommendations, and it doesn’t offer credit cards, loans, or savings accounts of its own.” Access is read-only. Anthropic adds that the tool “isn’t designed to give investment advice”.
ChatGPT. OpenAI previewed a personal finance experience on 15 May 2026 for Pro users in the US, and on 25 June said it “is now available to Plus and Pro users in the U.S.” So it too sits inside paid plans. OpenAI’s page also describes where it wants to go: a user “could go from getting a credit card recommendation to understanding their approval odds and submitting an application”, with Intuit as a partner. That is the path a referral business runs on. OpenAI’s page does not say whether any fee would change hands.
Robinhood Cortex. Robinhood sells its AI assistant as part of a subscription. Its support page says Cortex “is only available to our Robinhood Gold members ($5 monthly subscription)”. Robinhood’s 10-K calls Cortex “an AI investment tool”.
Our newsroom compared the Claude and ChatGPT terms line by line: they match on two of seven published terms and differ on five (the comparison).
Referral and lead-generation fees: the lender pays
A referral business is free to the user. It earns when the user takes a product from a partner. Intuit’s 10-K says Credit Karma revenue “is primarily comprised of” cost-per-action fees, “earned based on a predetermined fee for approved actions, such as when credit cards are issued or when personal loans and other loans to businesses are funded”. Credit Karma’s net revenue was $2,641 million in Intuit’s fiscal 2026 (the year to 31 July 2026), up 20%. Most of the growth came from personal loans (up $235 million), credit cards (up $101 million) and insurance (up $85 million).
NerdWallet works the same way. Its 10-K says it generates revenue “primarily through referral fees, lead generation, and partner-based monetization”. Its 2025 revenue was $836.6 million, led by insurance at $280.8 million. More: Credit Karma revenue and the NerdWallet business model.
Interchange: the card swipe pays
Every time you pay with a debit or credit card, the merchant’s side pays a small fee, and part of it reaches the bank that issued the card. A finance app that issues cards with a partner bank shares in that fee. Chime’s 10-K says: “Historically, a substantial majority of our revenue has been derived from interchange fees”. In 2025 its payments revenue, which is interchange-based, was $1,500.6 million of $2,186.8 million in total, or 69% by our arithmetic. Chime’s 10-K notes that certain interchange fees are regulated in the US, including debit card fees under the Durbin Amendment. More: how Chime makes money.
Interest and cash sweeps: the bank pays for your cash
Cash that sits in an app is valuable to a bank. Many apps “sweep” it to partner banks, which pay the app for the deposits. Wealthfront’s 10-K says its cashmanagementrevenue “primarily consists of fees earned from program banks in our cash sweep program”. It was $271.7 million of $365.0 million in the year to 31 January 2026: about 74%, as the filing also says. Robinhood earned $1,514 million of net interest revenue in 2025, 34% of its total.
A fee on assets: the user pays a percentage
Robo-advisers charge a yearly percentage of the money they manage. Wealthfront’s 10-K says its advisory fees are the fee rate “multiplied by” the market value of assets in client accounts; its most popular portfolio costs 0.25% a year. Investment advisory brought in $91.9 million, 25% of Wealthfront’s revenue. This route earns more as your balance grows, not as you buy products. More: robo-advisors, Wealthfront and Betterment.
Trading apps have one more route. Robinhood’s largest line in 2025, $2,628 million or 59%, was transaction-based revenue: money from market makers for routing customers’ orders, which for options and equities “are known as PFOF” (payment for order flow). More: how Robinhood makes money.
Data: the money flows the other way
“Data partnerships” in personal finance usually mean the app pays, not that it gets paid. Both Claude and ChatGPT link bank accounts through Plaid. Plaid’s billing documentation says that for Transactions, Liabilities and Investments “an Item will incur a monthly subscription fee as long as a valid access_token exists”: the app pays each month for each linked account it keeps. Balance checks are a flat fee per request. Plaid’s pricing page lists Pay as You Go, Growth and Custom plans, with no public per-product rates. Neither Anthropic nor OpenAI says what it pays Plaid.
Banks now charge the data networks too. Bloomberg Law reported on 15 September 2025 that “Plaid Inc. agreed to pay JPMorgan Chase & Co. for its consumer data”; the two “confirmed the fees but wouldn’t disclose the amount”. More: the Plaid business model.

Why it matters
The size of the audience is large. OpenAI’s chief financial officer, Sarah Friar, said on CNBC on 6 November 2026 that “200 million people” come to ChatGPT “for personal finance”; she did not say over what period (our piece). An assistant that reaches that many people could add any of the routes above. Which one it adds decides whose interest the assistant is paid to serve.
Apps built on top of the same models carry their own risk. Silvia, Inc. bought CFO Silvia, “an AI agent lab focused on finance”, on 6 April 2026 for total consideration of $23.3 million, its October prospectus says. The same filing lists the risk of a model provider’s “decision … to prioritize their own competing AI offerings” (our piece).
FAQ
How does Claude’s Personal Finance make money?
Through Claude’s paid plans. It is in beta in the US on Pro, Max and Ultra. Anthropic says it has no ads or sponsored recommendations and offers no credit cards, loans or savings accounts of its own.
Is ChatGPT’s personal finance feature free?
No. OpenAI says it is available to Plus and Pro users in the US. OpenAI’s page describes a future step with Intuit, from a credit card recommendation to an application, but does not say whether a fee would be paid.
How can a finance app be free?
Someone else pays. Credit Karma and NerdWallet earn referral fees from lenders and card issuers. Chime earns interchange on card swipes. Wealthfront earns fees from banks for the cash it sweeps to them.
What is interchange?
A fee paid on each card transaction by the merchant’s side, part of which reaches the bank that issued the card. Apps that issue cards with a partner bank share in it. Chime says it has historically made a substantial majority of its revenue this way.
Who pays Plaid?
The app that links your account. Plaid’s billing documentation describes a monthly fee per linked account for transaction data and a fee per request for balance checks. Plaid itself now pays JPMorgan for access to its customers’ data, Bloomberg Law reported.
Can an AI assistant give investment advice?
Anthropic says Claude’s Personal Finance “isn’t designed to give investment advice”, and that it is exploring how Claude could work alongside licensed professionals and regulated firms. Investment advice is a regulated activity; this page explains business models and is not financial advice.
Built from the FourWeekMBA newsroom’s coverage of Claude’s and ChatGPT’s finance tools, with every figure taken from the companies’ own pages and SEC filings. When a new 10-K lands for Robinhood, Chime, Wealthfront, NerdWallet or Intuit, or when an AI assistant adds a new way to get paid (referrals, ads, its own financial products), this page is updated with the new figures and date. This explains business models; it is not financial advice.
