American Century Investments is a premier global asset management firm headquartered in Kansas City, Missouri. Founded in 1958, the company is distinguished by its unique ownership structure, where a significant portion of its profits supports the Stowers Institute for Medical Research. It offers diverse investment strategies, including mutual funds, ETFs, and institutional services.
For over six decades, American Century Investments (ACI) has remained a pillar of the Kansas City business community. While it operates offices in New York, London, Hong Kong, and Sydney, its heart remains at the iconic 4500 Main Street address in Kansas City. This guide explores the firm’s local impact, its specialized investment products, and the unique philanthropic model that sets it apart from other Wall Street entities as of 2026.
The History and Evolution of American Century in Kansas City
The story of American Century Investments is inextricably linked to the vision of its founder, James E. Stowers Jr. In 1958, Stowers started the firm—then known as Twentieth Century Mutual Funds—with just $100,000 in assets and a handful of investors. Operating out of a small office in Kansas City, Stowers was a pioneer in using computer-based systems to analyze market trends, a precursor to the algorithmic trading common in 2026.
The firm’s growth was exponential through the 1970s and 1980s, fueled by the success of its "Select" and "Growth" funds. In 1997, the company rebranded as American Century Investments to reflect its broadening scope and its commitment to the American investor. Despite its global expansion, the firm has resisted the urge to relocate its headquarters to traditional financial hubs like New York or Chicago, maintaining that its Midwestern roots provide a stable, long-term perspective on market volatility.
In the mid-2020s, American Century continues to leverage this Kansas City heritage to attract talent who seek a balance between high-level financial careers and the quality of life offered by the Missouri-Kansas region. The firm’s presence has been a catalyst for the "Animal Health Corridor" and the broader financial services ecosystem in the Kansas City metro area.
The Stowers Institute: A Unique Ownership Model
Perhaps the most compelling aspect of American Century Investments in Kansas City is its relationship with the Stowers Institute for Medical Research. In 2000, James and Virginia Stowers established the Institute with a massive endowment of American Century stock.
How the Partnership Functions
As of 2026, the Stowers Institute owns a controlling interest (approximately 40%) of American Century Investments. This means that a substantial portion of the firm's annual profits—distributed as dividends—goes directly to funding basic biomedical research. This research focuses on the genetic underpinnings of diseases such as cancer, diabetes, and Alzheimer’s.
This "prosper with a purpose" model serves as a powerful differentiator for the firm. Investors are often drawn to ACI not just for their alpha-seeking strategies, but because their management fees are effectively contributing to life-saving medical breakthroughs. Since the inception of this arrangement, more than $2 billion in dividends has been directed to the Institute, much of which stays within the Kansas City scientific community.
Impact on Local Innovation
The Stowers Institute, located near the American Century campus, has turned Kansas City into a global hub for genomic research. The synergy between the financial success of ACI and the scientific achievements of the Institute has created a self-sustaining cycle of innovation that benefits the local economy and global health.

No, American Century Investments is a privately held company. Its ownership is shared between the Stowers Institute for Medical Research and the Stowers family, along with a minority stake held by Nomura Holdings, Inc. This private status allows the firm to focus on long-term investment results rather than quarterly earnings pressure from public shareholders.
Can I visit the Kansas City headquarters for investment advice?
The 4500 Main Street location serves primarily as corporate offices. While they do have client service capabilities, most individual investor interactions are handled through their digital platforms or dedicated phone lines. However, they frequently host educational seminars and community events in the Kansas City area.
How does the Stowers Institute benefit from my investment?
When you invest in an American Century fund, the management fees you pay contribute to the firm's overall profitability. Because the Stowers Institute owns a large portion of the company’s equity, it receives a corresponding share of the profits as dividends.

What are the main differences between American Century and Avantis Investors?
Avantis Investors is a brand of American Century that utilizes a systematic, research-driven approach to capture market "factors" (like value or momentum) rather than purely subjective stock picking.
