Betterment and Capitalize Tackle the $1.6 Trillion 401(k) Problem

NEW YORK, NY – January 22, 2026 – Wealth management platform Betterment and fintech firm Capitalize have announced a partnership aimed at modernizing one of the most notoriously cumbersome processes in personal finance: the 401(k) rollover. By integrating Capitalize's digital transfer technology directly into its platform, Betterment intends to help its customers seamlessly find and consolidate old retirement accounts, tackling a systemic issue that has left trillions of dollars in savings languishing in forgotten accounts.

The collaboration will embed Capitalize’s Rollover API into the Betterment user experience, allowing customers to digitally locate and transfer funds from previous employer-sponsored plans into a Betterment Individual Retirement Account (IRA). This move is designed to replace a process often mired in paperwork, phone calls, and physical checks with a streamlined, digital-first solution.

“At Betterment, our mission is to empower people to build wealth with confidence and ease, and retirement plays a critical role in that journey,” said Mike Reust, President at Betterment, in the announcement. “Account rollovers are an important moment for investors, yet the process has remained unnecessarily complex for far too long. We’re excited to partner with Capitalize to help our customers consolidate their 401(k)s in a more modern, intuitive way.”

Gaurav Sharma, CEO and Co-Founder of Capitalize, echoed this sentiment, stating, “Together, we’re addressing one of the biggest gaps in the retirement savings market by ensuring people make the most of their hard-earned 401(k) savings by consolidating them effectively. This partnership reflects a shared commitment to helping Americans grow their wealth using innovative investing and leading technology.”

A System Plagued by Complexity

The partnership directly confronts the widespread problem of "forgotten" or "orphan" 401(k) accounts. As employees change jobs with increasing frequency, many leave their retirement savings behind with former employers. The complexity of moving these funds often proves to be a significant deterrent.

Recent industry research paints a stark picture of the issue. Over 30 million 401(k) accounts have been left behind by former employees, holding an estimated $1.65 trillion in assets. These "zombie accounts" often suffer from neglect, with funds remaining in low-yield cash-equivalent investments that fail to keep pace with inflation, or being slowly eroded by administrative fees.

The rollover process itself is a major culprit. Historically, it has been a manual, paper-intensive ordeal that can take weeks or even months to complete. One study found that only 22% of savers manage to complete a rollover without assistance. The difficulties range from simply locating old accounts—a challenge for 54% of individuals—to remembering login credentials. This friction leads many to either abandon the process or, in a worse-case scenario, prematurely cash out their savings, incurring taxes and penalties that can devastate their long-term retirement goals.

"The retirement industry has, in many ways, been stuck in the past compared to the digital transformation we've seen elsewhere in finance," noted one independent fintech analyst. "Moving money between bank accounts is nearly instantaneous, but moving your life's savings from an old 401(k) can feel like a trip back to the 1990s. There's a massive consumer demand for a better way."

A Modern Solution Through Embedded Technology

The Betterment-Capitalize integration exemplifies the rise of "embedded finance," where specialized financial technology is seamlessly woven into the user experience of a broader platform. Instead of sending users to an external website or providing them with a checklist of manual tasks, the new solution will handle the heavy lifting directly within the Betterment app.

Capitalize’s Embedded Rollover API allows financial institutions to offer a "white-labeled" rollover service that feels native to their own platform. For a Betterment customer, the experience will involve a few simple steps: the technology helps them digitally locate their legacy 401(k) accounts from previous employers, then guides them through initiating the transfer request. Capitalize's platform, which is SOC 2 Type 2 certified for security, manages the complex backend logistics, interacting with thousands of different plan administrators to ensure the funds are moved efficiently and securely.

This approach transforms a process that could take nearly two months into a far more frictionless digital workflow. By digitizing the discovery and transfer initiation, the partnership aims to eliminate the primary sources of friction—paperwork, faxes, and follow-up calls—that cause so many rollovers to fail. This not only improves the user experience but also minimizes the time that an investor's funds are out of the market during the transfer.

Strategic Implications for the Wealth Management Landscape

For Betterment, a leading robo-advisor with over one million customers and more than $65 billion in assets under management, the partnership is a significant strategic move. In the highly competitive wealth management space, providing a seamless, end-to-end user experience is a key differentiator. By solving the rollover headache, Betterment can more effectively attract new customers and encourage existing ones to consolidate more of their assets onto its platform.

Higher assets under management (AUM) directly translate to increased revenue for platforms like Betterment. Facilitating large rollovers—the average for individuals over 50 is over $220,000—is one of the most effective ways to grow AUM. This integration removes a major barrier that may have prevented potential customers from moving their substantial retirement nest eggs to the platform.

For Capitalize, this partnership with a major player like Betterment further validates its API-first business model. Having already secured integrations with other platforms like Public and Firstrade, Capitalize is positioning itself as the go-to infrastructure provider for retirement asset movement. This B2B2C (business-to-business-to-consumer) strategy allows it to scale its technology far more rapidly than a purely direct-to-consumer approach would allow.

Unlocking Trillions in Dormant Retirement Savings

Beyond the benefits for the two companies and their customers, the broader economic implications are substantial. The U.S. rollover market is immense, with an estimated $1 trillion in assets moved in 2025 and projections showing that figure climbing to $1.15 trillion by 2030. Simplifying this process can make the market more efficient and, more importantly, help activate the $1.65 trillion currently sitting in stagnant, forgotten accounts.

When these dormant funds are consolidated into actively managed IRAs, they are typically reinvested into diversified, growth-oriented portfolios. This not only benefits the individual saver by putting their money back to work for their future but also channels a massive amount of capital back into the broader economy.

As the American workforce continues to be defined by mobility and frequent job changes, the number of dormant 401(k)s is projected to grow, reaching nearly 33 million by 2026. Solutions that make it easy for individuals to maintain control over their retirement assets across multiple jobs are no longer a luxury but a necessity for ensuring national retirement security. This partnership represents a significant step in that direction, leveraging technology to empower individuals and address a systemic weakness in the country's retirement infrastructure. The offering is expected to become available to Betterment's retail customers in the coming weeks.
