An AI robo-advisor can build and run a diversified portfolio for you with little human involvement, but in the big US services the “AI” part is mostly rules-based software, not a chatbot making investment calls. Generative AI shows up at the edges: summaries of why your portfolio moved, and screening tools that turn a prompt into a basket of stocks. None of them can promise better returns, and regulators have already fined firms that overstated their AI.

So the practical question is not “can AI manage my money?” but “what exactly is this service automating, what does it cost, and who is legally responsible for the advice?” This guide answers those three questions for the best-known US options, using their own fee pages and regulatory filings.

What a robo-advisor actually does

The SEC describes a robo-adviser as an automated digital investment advisory program: you fill in an online questionnaire about your goals, time horizon, income and risk tolerance, and the program builds and manages a portfolio from your answers (SEC Investor Bulletin). Most of the work after that is mechanical: buying the model portfolio, reinvesting dividends, rebalancing when prices drift, and in taxable accounts selling losing positions to capture tax losses.

Two points from the SEC’s guidance matter for anyone weighing an “AI” version:

  • A robo-advisor is still a registered investment adviser. Automated or not, it must follow the Investment Advisers Act and owes you the same fiduciary duty as a human adviser (SEC press release). You can look up any firm in the SEC’s Investment Adviser Public Disclosure database on Investor.gov.
  • The advice is only as good as the questionnaire. The SEC staff found that some questionnaires ask only for age, income and goals, and give you no way to add context (SEC staff guidance). If you are saving for a house in three years, a tool that sets your time horizon from your age alone can put you in the wrong mix. Keeping your answers up to date is your job.

Where AI is used in 2026, and where it is not

“AI-powered” covers three quite different things. It helps to know which one you are buying.

Type What the software does Example Who decides what you own
Classic robo-advisor Algorithms allocate across a set of funds, rebalance, harvest tax losses Betterment, Wealthfront, Vanguard Digital Advisor, Schwab Intelligent Portfolios The firm’s investment team designs the models; software executes them
Managed portfolio with AI summaries A human-run portfolio, plus generative AI that explains recent moves Robinhood Strategies The investment team; Robinhood says it does not use AI to make investment decisions (Robinhood brochure)
Prompt-built portfolios You describe a theme in plain language; AI agents screen stocks and assemble an index you can invest in Public Generated Assets You: Public says the output is not a recommendation and suitability is your responsibility (Public)

Robinhood Strategies is a useful example of how the labels work in practice. Its advisory brochure says the portfolio management team makes the investment decisions, while “Digests” use generative AI to summarize news and market data about your holdings, focusing on the biggest contributors and detractors. The firm does not review every Digest before it goes out and does not guarantee their accuracy (Robinhood brochure). Digests are only for clients who also pay for Robinhood Gold (Robinhood Strategies FAQ).

Public’s Generated Assets goes furthest toward “AI picks the stocks.” You type a thesis, such as a theme or a set of financial filters; a first agent extracts the criteria, a swarm of evaluation agents screens thousands of stocks against them, and the results are weighted into an index (Public). You can backtest it against the S&P 500 and then invest in it directly (Public). Two things to keep in mind: a backtest shows hypothetical past performance, not a forecast, and the tool follows your idea rather than checking whether that idea suits your finances. Public states plainly that you are solely responsible for deciding whether to invest in what you built (Public).

General chatbots such as ChatGPT, Claude or Gemini are not registered investment advisers and do not hold or trade your money. They can explain concepts or check arithmetic, but the SEC, NASAA and FINRA warn that AI-generated information can rest on inaccurate or outdated data, including information planted to move a stock, and can be “completely made up” even from good inputs (Investor.gov). Our guide to where AI gets money wrong covers how to check a chatbot’s numbers.

What the main robo-advisors cost

Fees below are the advisory fee only. You also pay the expense ratios of the funds inside the portfolio, and the SEC reminds investors that a low advisory fee paired with expensive funds can still add up to a high total cost (SEC Investor Bulletin).

Service Advisory fee Minimum to start Notes
Betterment $5 a month, or 0.25% a year once you deposit $200+ a month or hold $24,000+ (Betterment) None Premium with advisor access: 0.65% a year
Wealthfront 0.25% a year (Wealthfront) $500 (Wealthfront Support) Stock-level tax-loss harvesting from $100,000
Vanguard Digital Advisor About $15–$16 a year per $10,000 in an all-index portfolio, fund costs included; no advisory fee for the first 90 days (Vanguard) $100 Includes debt payoff and emergency fund tools
Schwab Intelligent Portfolios No advisory fee (Schwab fact sheet) $5,000 Schwab earns revenue from its own ETFs and the cash held in the portfolio
Robinhood Strategies 0.25% a year; Robinhood Gold members pay it only on the first $100,000 per account (Robinhood) Gold costs $5 a month or $50 a year

A worked example shows why the fee structure matters more than the headline rate. On a $10,000 balance, a 0.25% fee is $25 a year. Betterment’s flat $5 a month, which applies if you are below $24,000 and not depositing $200 a month, is $60 a year on the same balance, or 0.6%. Setting up a $200 monthly deposit moves you to the 0.25% rate.

“No fee” is not the same as “free.” Schwab’s own fact sheet says its affiliates earn money from the Schwab ETFs used in the portfolios and from the cash allocation (Schwab fact sheet). The SEC suggests asking every robo-advisor how it is paid and whether that creates a conflict, for example if it mostly offers its own funds (SEC Investor Bulletin).

Tax-loss harvesting is often pitched as paying for the fee. Wealthfront and Betterment both make that claim on their pricing pages, based on their own calculations. How much it is worth to you depends on your tax bracket, whether the account is taxable at all (it does nothing in an IRA or 401(k)), and the wash-sale rules, which is why the SEC suggests asking a tax adviser (SEC Investor Bulletin).

Can AI beat the market?

Nothing in the regulatory record says it can do so reliably, and firms that promised it have been fined.

In March 2024 the SEC brought its first “AI washing” cases against two investment advisers. Delphia told clients it used AI and machine learning on their spending and social media data to pick investments; the SEC found it never used that data at all. Global Predictions called itself the “first regulated AI financial advisor” and advertised AI-driven forecasts it could not back up. The firms paid $225,000 and $175,000 in penalties (SEC). Delphia ran robo-advisory accounts for about 29,000 retail clients (SEC order).

Outside registered firms, the picture is worse. The CFTC warns that AI cannot predict the future or sudden market changes, and points to a trading-bot scheme that promised at least 10% a month and took about $1.7 billion in bitcoin from at least 23,000 people (CFTC). If an app or influencer promises guaranteed returns from an AI trading system, treat it as a scam until proven otherwise; our review of AI Wealth Machine walks through one such pitch.

What automation does well is the boring part: staying invested, rebalancing on schedule, and not panic-selling. That discipline is valuable, but it is available from rules-based robo-advisors that have been running for more than a decade, without a generative AI layer on top.

How to check an AI investing app before you fund it

  1. Look it up on Investor.gov. A US firm that manages your portfolio should be registered as an investment adviser. The SEC, NASAA and FINRA say an unregistered promoter is a prompt to investigate further before you invest anything (Investor.gov).
  2. Read Form ADV Part 2. This plain-language brochure says how the firm is paid, what it invests in and, increasingly, where it uses AI. Robinhood’s brochure, for instance, has a section on AI-generated content risk.
  3. Find out who makes the decisions. Is AI choosing investments, summarizing them, or only screening at your request? The answer changes who is responsible when something goes wrong.
  4. Add up the total cost. Advisory fee, fund expense ratios, any subscription needed to unlock features, and what you give up by holding cash in the portfolio.
  5. Check how you leave. The SEC and FINRA suggest finding out how to end the agreement and how long it takes to get your money out (Investor.gov).
  6. Be skeptical of backtests and performance claims. Global Predictions advertised hypothetical results for years before it existed (SEC order).

If you have a large sum, a complicated tax position or several goals competing for the same money, a human fee-only adviser may be worth the higher cost. Several robo-advisors, such as Betterment Premium, offer a hybrid where you can reach a person.
