The Largest Robo-Advisors by AUM (2026)

Robo-advisors have expanded rapidly over the past decade as investors sought low-cost, automated wealth management. The industry now includes a mix of independent fintech startups and established institutions, with the former’s growth pushing several major banks and brokerages to launch or acquire their own automated advisory offerings.

Robo-advisors can be compared on several metrics, including fees, service breadth, and client numbers. However, Assets Under Management (AUM) remains the clearest single indicator of scale, client trust, and commercial traction – and, since most platforms charge a percentage of AUM as their management fee, it is also the primary driver of their revenue.

Here is the list of the largest global robo-advisors ranked by Assets Under Management:

The robo-advisory market

Robo-advisors are part of the financial technology (fintech) wave that is reshaping the wealth management industry. Although still relatively new, this model has grown remarkably over the years.

According to Statista, the robo-advisory market is expected to reach $7 trillion in AUM by the end of 2029.

Vanguard Digital Advisor remains the largest robo-advisor with over $311 billion, followed by Empower, formerly Personal Capital, at $200 billion. Wealthfront now reports $93.2 billion in platform assets and Wealthsimple CAD 124.8 billion in assets under administration, putting both ahead of every other pure-play digital wealth manager.

Betterment, launched in 2008 and the first robo-advisor in the US, has passed $65 billion and one million clients.

One caveat before reading the numbers below: providers do not all report on the same basis. Some disclose discretionary assets under management, some report total platform assets including cash and self-directed accounts, and bank or broker-owned services often publish only a group-wide figure. Each entry states which basis applies.

What are assets under management (AUM)?

AUM refers to the market value of the assets a company manages on behalf of its clients. It is a key performance indicator that measures a firm’s success in attracting customers and growing its market share.

For robo-advisors this metric is central to revenue. Most platforms charge a fee expressed as a percentage of assets under management, known as a management fee, generally ranging from 0.25% to 1.00%.

Two related terms appear throughout this page. Assets under administration (AUA) covers everything held on a platform, including assets the provider does not manage on a discretionary basis. Platform assets is a broader still measure that can include cash management balances. Neither is directly comparable to discretionary AUM.

The largest robo-advisors reviewed

Vanguard Digital Advisor

• AUM: $311.9B
• Number of clients: 792K+
• Reporting basis: discretionary AUM
• Reporting date: July 2024

Vanguard offers two robo-advisory services for investors looking for low-cost, automatically managed portfolios: Vanguard Digital Advisor, with a minimum investment of $3,000, and Vanguard Personal Advisor, aimed at high net worth investors with a minimum of $50,000.

As of July 2024, more than 792,000 clients were on board and Vanguard’s AUM reached $311.9 billion. Vanguard does not publish an AUM figure on the Digital Advisor product page, so this number comes from its Form ADV filing.

Empower (former Personal Capital Advisors)

• AUM: $200B
• Number of clients: 236K+ investment accounts, 18M+ total customers
• Reporting basis: wealth management arm
• Reporting date: September 2024

Empower is a popular robo-advisor for high net worth individuals, offering advanced personal finance tools for free alongside a comprehensive wealth management service with access to financial advisers.

As of September 2024, the assets under management of Empower stood at $200 billion across more than 236,000 investment accounts. Empower serves over 18 million customers across all its services, with more than 82,000 retirement plans under administration. Note that the multi-trillion figure that appears elsewhere on Empower’s website is group-wide assets under administration, not the wealth management arm.

Empower has a minimum investment of $100,000 and charges an annual fee of 0.89% of AUM, decreasing as assets grow, with additional services such as estate and tax professional access becoming available at higher tiers. Empower Personal Cash offers a higher interest rate on cash with no minimum balance.

Wealthfront

• Platform assets: $93.2B
• Number of clients: 1.44M funded clients
• Reporting basis: platform assets, including cash management
• Reporting date: March 2026

Wealthfront is a well-known US robo-advisor that has been building personalised portfolios since 2008. A minimum deposit of $500 is required and portfolios are constructed using exchange-traded funds. The annual portfolio management fee is 0.25% of AUM.

As of March 2026, Wealthfront’s platform assets reached $93.2 billion across 1.44 million funded clients. This figure includes the cash management business, which accounts for roughly 74% of company revenue, so it is materially higher than the discretionary advisory book alone. Wealthfront trades on NASDAQ under the ticker WLTH.

The platform offers a wide range of products and tools, including a cash account, a portfolio line of credit, and the free Path tool for goal-based financial planning covering objectives such as buying a home, retiring early or saving for university.

Wealthsimple

• AUA: CAD 124.8B (~$91.1B)*
• Number of clients: 3.4M
• Reporting basis: platform-wide AUA, not robo-advisory only
• Reporting date: March 2026

Wealthsimple is a fintech company founded in 2014 offering wealth management to Canadian investors with no minimum balance.

As of March 2026, Wealthsimple’s assets under administration reached CAD 124.8 billion with 3.4 million clients. This covers the entire platform, including self-directed trading, cash and crypto, rather than the managed portfolios alone.

The company offers three main propositions: Wealthsimple Invest, the managed portfolio service; Wealthsimple Cash, a spending account and card; and Wealthsimple Trade, commission-free stock and ETF trading. Investors can choose from socially responsible and halal portfolios, and Wealthsimple Generations provides additional benefits and lower fees for clients above CAD 500,000.

Questwealth Portfolios

• Group AUA: CAD 100B+ (~$73.0B)*
• Number of clients: not disclosed
• Reporting basis: Questrade group AUA, robo not broken out
• Reporting date: June 2026

Questwealth Portfolios is the robo-advisory service of Questrade Wealth Management. Launched in 2018, it has become a popular option in Canada thanks to low fees and ease of use, and is available in both English and French.

Questrade does not disclose Questwealth assets separately. In June 2026 the company reported more than CAD 100 billion in assets under administration across the whole brokerage, up from roughly CAD 85 billion in late 2025. The robo-advisory service is an undisclosed share of that total, so the figure should not be read as a like-for-like comparison with pure-play robo-advisors.

Questwealth charges 0.25% a year on the first CAD 100,000 and 0.20% above that. Clients can also access human financial advisers for guidance and support.

Betterment

• AUM: $65B+
• Number of clients: 1M+
• Reporting basis: discretionary AUM
• Reporting date: May 2026

Established in 2008, Betterment is a pioneering robo-advisor providing automated portfolio management. It combines Modern Portfolio Theory with proprietary algorithms to tailor portfolios to each investor’s goals, risk tolerance and time horizon.

As of May 2026, Betterment reported over $65 billion in AUM and more than one million clients.

Betterment suits a broad range of investors. Betterment Digital charges a management fee of 0.25% of AUM, with optional paid access to financial advisers. Betterment Premium provides unlimited access to certified financial planners along with tailored planning for an annual fee of 0.40% and a minimum balance of $100,000.

Moneybox

• AUA: £23B (~$31.1B)*
• Number of clients: 1.9M+
• Reporting basis: platform AUA, including cash savings
• Reporting date: July 2026

Moneybox is a UK digital wealth platform launched in 2016 that combines saving, investing, home buying and retirement products in a single app. It is best known for round-up saving and for the Lifetime ISA.

As of July 2026, Moneybox reported more than £23 billion in assets under administration and over 1.9 million customers, alongside a valuation of roughly £800 million following a secondary share sale on the London Stock Exchange’s PISCES market. The company reported revenue above £115 million in 2025 and a third consecutive profitable year.

The AUA figure covers the full platform, including cash savings accounts, so it is not directly comparable to a discretionary AUM number.

Acorns

• AUM: $30B+
• Number of users: 14M+
• Reporting basis: discretionary AUM
• Reporting date: July 2026

Acorns is a US robo-advisory firm established in 2014, offering investment, checking and retirement accounts through its mobile app. As of July 2026, Acorns’ assets under management exceeded $30 billion with more than 14 million users.

Clients receive personalised portfolios aligned with their long-term goals and risk tolerance. Acorns is best known for its round-up feature, which invests spare change from everyday purchases. The company runs a subscription model with monthly fees, no minimum deposit to open an account, and investing available from $5.

M1 Finance

• Client assets: $12.5B
• Number of clients: 1M+
• Reporting basis: platform assets, mostly self-directed
• Reporting date: December 2025

M1 Finance is a fintech company providing commission-free investing alongside borrowing and banking services.

In its year-end letter published in January 2026, M1 reported passing $12.5 billion in client assets, with a user base above one million. Most of that total sits in self-directed brokerage accounts rather than discretionary mandates, which distinguishes M1 from a conventional robo-advisor.

Clients build a personalised portfolio or choose from pre-built ones, presented as pies with a clear allocation for each holding. The basic app is free; M1 Plus adds higher cash yields, cash back on purchases and access to a credit line.

J.P. Morgan Personal Investing (former Nutmeg)

• AUM: £8.5B (~$11.5B)*
• Number of clients: 265,000
• Reporting basis: discretionary AUM
• Reporting date: October 2025

Founded in 2011, Nutmeg became the largest robo-advisor in the UK before being acquired by JPMorganChase in 2021. The Nutmeg brand was retired on 3 November 2025 and the business now trades as J.P. Morgan Personal Investing, available directly and through the Chase UK app.

At the time of the rebrand the business managed more than £8.5 billion for over 265,000 investors, up from £3.5 billion and 140,000 clients at acquisition.

Portfolios are offered across several investment styles with different risk levels, including fixed allocation, fully managed, socially responsible and Smart Alpha portfolios powered by J.P. Morgan Asset Management. Clients with more than £250,000 invested have access to a dedicated relationship manager, and a full DIY investment platform was announced for 2026.

Moneyfarm

• Total assets: £5B (~$6.8B)*
• Number of clients: 165,000+
• Reporting basis: total assets, managed plus DIY and cash
• Reporting date: June 2025

Moneyfarm is a pan-European digital wealth manager founded in 2011 in Italy and launched in the UK in 2016. In its first-half 2025 results the company reported total assets above £5 billion, up 36% year on year, with active clients up 33% to more than 165,000. The Italian release put the same milestone at €6.5 billion.

Moneyfarm offers seven personalised portfolios covering different risk profiles, including socially responsible ETFs. Portfolios can be actively managed, with the investment team monitoring and rebalancing in response to market developments, or held as fixed allocation portfolios rebalanced once a year. The range has since widened to include a SIPP, Liquidity+ money market portfolios, a cash ISA and DIY share investing, which is why the headline figure is described as total assets rather than discretionary AUM.

Moneyfarm uses a tiered fee structure ranging from 0.25% to 0.75% a year, and investment consultants are available to discuss market events and portfolio performance.

SigFig

• AUM: $3.58B
• Number of accounts: 106,361
• Reporting basis: discretionary AUM
• Reporting date: December 2025

SigFig is a portfolio management and robo-advisory firm founded in 2011 that partners with banks and brokerages to power their digital advice programmes.

According to its Form ADV filing, SigFig managed approximately $3.58 billion on a discretionary basis as of 31 December 2025, across 106,361 accounts. The firm reports no non-discretionary assets, which makes this one of the cleanest like-for-like figures in the table.

SigFig’s account aggregation and portfolio analysis features give investors a consolidated view of their holdings. The firm also offers a free portfolio tracker to anyone who links their investment accounts.

Schwab Intelligent Portfolios

• AUM: not disclosed separately
• Number of clients: not disclosed separately
• Reporting basis: aggregated into managed investing solutions

Schwab Intelligent Portfolios is the robo-advisory service of Charles Schwab, offering automated portfolio management built from ETFs.

Schwab no longer breaks out Intelligent Portfolios in its financial reporting, folding it into a broader managed investing solutions line, so no current standalone AUM figure exists. The Intelligent Portfolios Premium tier, which paired the automated service with unlimited access to certified financial planners, was discontinued in 2026.

Zacks Advantage

• AUM: not disclosed separately
• Number of clients: not disclosed
• Reporting basis: parent firm RAUM only
• Reporting date: May 2026

Zacks Advantage is a robo-advisor owned by Zacks Investment Management, a subsidiary of one of the largest investment research firms in the US. The service is still available, but the company does not publish assets for the robo-advisor on its own.

The most recent Form ADV, filed in May 2026, reports roughly $14.59 billion in firm-wide regulatory assets under management across all Zacks Investment Management strategies. Zacks Advantage is an undisclosed portion of that total.

The platform combines low-cost ETFs with an active management overlay, building portfolios around each client’s goals and risk tolerance and monitoring them on an ongoing basis.

Conclusion

Robo-advisors offer a wide range of services and remain a convenient wealth management option. Each company delivers its own mix of features at different prices, but the shared aim is the same: automated investment portfolios at a low cost, for investors who may not meet the minimums of traditional wealth management firms.

AUM changes over time with market movements, client deposits and withdrawals, and is typically updated quarterly. A higher AUM does not mean a platform offers better services or stronger performance, and a lower AUM does not make a robo-advisor less trustworthy.

Comparisons also need care because providers do not report on the same basis. Some publish discretionary assets under management, others report total platform assets that include cash accounts and self-directed trading, and bank or broker-owned services often disclose only a group-wide figure with the robo-advisor folded in. Two numbers of similar size can therefore describe very different businesses.

We encourage investors to check each company’s regulatory filings and website, and to do their own due diligence on the services and costs before opening an account with any robo-advisor.
