Wealthfront Corporation, the automated investing platform that has traded on Nasdaq as WLTH since completing its initial public offering in December 2025, told investors on 9 September 2026 that its Total Platform Assets reached $99.0 billion at the end of its fiscal second quarter, up 12% from a year earlier. By the end of August the company said it had passed $100 billion, a level it reached in under three years after first crossing half that figure. For a robo-adviser sector that spent recent years being described as mature rather than growing, it is a rare, dated data point pointing the other way.

Assets cross the $100 billion line

The figures come from Wealthfront’s fiscal second quarter earnings release, filed with the US Securities and Exchange Commission on 9 September 2026. For the three months to 31 July 2026, the company reported Total Platform Assets of $99.0 billion, 1.51 million funded clients, up 14% year on year, and 1.97 million funded accounts, up 15%. Total revenue was $91.9 million, roughly flat on the prior year, because growth came disproportionately from lower-fee investment accounts rather than the cash management product that had driven more of the company’s revenue growth in 2025.

Investment advisory assets, not just cash, are doing the growing

The split between Wealthfront’s two main products matters more than the headline figure. Investment Advisory Assets, the automated portfolios that make up the core robo-adviser product, rose 30% year on year to $54.1 billion. Cash Management Assets, the higher-yield savings product that drove much of the company’s growth in 2023 and 2024, fell 4% to $44.9 billion. That shift points to clients allocating new money to managed portfolios rather than only parking cash for the yield, a stronger signal for the advisory business than cash balances alone.

The distinction matters for how the growth should be read. Investment Advisory Assets generate fees priced as a share of assets managed, the economics a robo-adviser is built on. Cash Management Assets mostly generate revenue through interest rate spreads paid by partner banks, a business that depends more on Federal Reserve policy than on how many portfolios software can manage. A quarter in which advisory assets outgrew cash assets by this margin suggests Wealthfront’s core product, rather than a favourable rate environment, is doing more of the work.

The quarter was not without strain. GAAP diluted net income fell to $17.6 million from $34.7 million a year earlier, and diluted earnings per share dropped to $0.10 from $0.24. Wealthfront attributes the decline to higher stock-based compensation tied to dual-trigger awards that vested following the IPO, not to a weaker underlying business: adjusted EBITDA, which excludes that charge, fell by a smaller 15% to $38.1 million. The company repurchased 3.3 million shares for roughly $30 million during the quarter and ended it with cash balances above $450 million and no debt.

A public robo-adviser puts a scoreboard on the category

Wealthfront’s prospectus, filed with the SEC on 12 December 2025, made it the first large, pure-play US robo-adviser to list on a public market. That matters beyond Wealthfront’s own results. Betterment, Schwab Intelligent Portfolios and Vanguard Digital Advisor remain the category’s other major US platforms, but none files the kind of quarterly, audited figures a listed company now has to produce. Wealthfront’s numbers are, for now, the only contemporaneous, independently verifiable scorecard the category has.

The IPO has produced a steady run of insider stock sales too, visible in dozens of Form 144 notices Wealthfront insiders filed with the SEC between June and September 2026. That is a routine feature of the year after a lock-up expires rather than a signal about the business itself, but it is the kind of detail a private robo-adviser would never have to disclose, and it is now part of the public record alongside the growth figures.

Chief executive David Fortunato described the $100 billion milestone as the result of “the purposeful construction of a durable business model” built around client wealth-building over time, including “significant life decisions such as buying homes and starting families.” Chief financial officer Alan Imberman said the company’s “product-led growth strategy drove another strong quarter of adjusted free cash flow” while funding new product lines.

Automation is moving beyond the portfolio

Much of that reinvestment is going into products that extend automation past the original robo-adviser pitch of index-based portfolio management. Wealthfront Home Lending, an automated mortgage product the company says is designed to be handled entirely from a mobile app, reached general availability in Texas in May 2026 and California in August 2026, adding to an earlier Colorado launch, with Washington, Florida, Illinois and Oregon next. The company says the product has priced loans at least 50 basis points below the national average on average since launch, and it has added automated income verification for borrowers paid partly in restricted stock, a step toward the kind of AI-driven, document-light underwriting that distinguishes a modern automated lender from a traditional mortgage broker.

Wealthfront launched Custodial Accounts in the quarter, aimed at parents investing on behalf of children, with an automated tax-gain harvesting strategy built in. Fintechly has previously covered how automated advice is being built directly into other financial products rather than sold as a standalone app, and Wealthfront’s expansion from portfolios into lending and family accounts follows that same logic: the advisory engine becomes the base layer for several products rather than the product itself.

The rest of the category has not shown its hand yet

None of this proves every robo-adviser is growing at Wealthfront’s pace. Betterment and the bank-owned platforms it competes with do not publish comparable quarterly breakdowns of advisory versus cash assets, so there is no way to confirm whether the same shift toward managed portfolios is happening across the category or is specific to Wealthfront’s client base and product mix. What is confirmed is that the largest independent robo-adviser to go public in the US is reporting double-digit asset and client growth, concentrated in the product that defines the category rather than the cash account that had been propping up revenue.
