If your retirement savings are currently parked in a broad index fund, billionaire entrepreneur Mark Cuban warns that you might inadvertently be contributing to America’s escalating healthcare crisis. By holding shares in massive funds that invest heavily in the nation’s largest health insurance carriers, Cuban argues that everyday investors are empowering corporations that prioritize share prices and profits over patient care.
The Hidden Cost of Passive Investing in Big Insurance
Passive investing through a 401(k) is the cornerstone of American retirement planning. According to recent data, approximately 61% to 62% of Americans owned stocks in 2025, largely through mutual funds and retirement accounts. While this strategy offers unparalleled diversification, it also means your money is likely funding major healthcare conglomerates.
For instance, Vanguard’s Total Stock Market Index Fund—available as the mutual fund VTSAX or the ETF VTI—is a staple in many portfolios. As of its March 2026 filing, the fund held nearly $2 trillion in investments overall, with significant positions in industry giants like UnitedHealth Group, CVS Health, Cigna, Elevance Health, Humana, and Centene. Cuban challenges investors to confront their fund managers, stating, “Tell the funds you own that you will sell if they don’t divest their interests in the biggest insurance companies. You can make a difference.”
How Insurers Profit at the Expense of Patients
The financial burden on American families is staggering. The average annual premium for employer-sponsored family health coverage reached $26,993 in 2025, with workers contributing an average of $6,850 directly from their paychecks. Meanwhile, the average American spent around $14,775 on health care in 2024—roughly twice the “comparable country” average of $7,860, and over $5,000 more than Switzerland, the next highest spender.
Cuban argues that insurance companies inflate these costs through aggressive claims management and payment practices. He claims that major insurers “underpay, late pay, delay, deny,” deliberately holding onto collected premiums as long as possible to earn interest on the float. This strategy maximizes their financial returns while patients are left waiting for critical treatments, including cancer care.
Regulatory Scrutiny: The FTC and HHS Step In
These practices have not gone unnoticed by federal regulators. In 2022, the Department of Health and Human Services (HHS) Office of the Inspector General reviewed claim denials from 15 of the largest Medicare Advantage insurers. The investigation revealed that 13% of denials for prior authorization requests actually met Medicare’s coverage rules and likely would have been approved under original Medicare.
Furthermore, the Federal Trade Commission (FTC) has closely examined Pharmacy Benefit Managers (PBMs) tied to these insurers, such as CVS Health’s Caremark, Cigna’s Express Scripts, and UnitedHealth Group’s OptumRx. The FTC found that between 2017 and 2022, these entities generated more than $7.3 billion in revenue above estimated drug acquisition costs, sometimes marking up medications by hundreds or thousands of percent.
Despite these critiques, the insurance industry fiercely defends its model. UnitedHealth Group, for example, reported that it negotiated nearly $300 billion in discounts for its customers in 2025, arguing that without their scale, premium increases would have been at least twice as large.
Value-Based Investing: Can You Dump Big Insurance?
For investors moved by Cuban’s call to action, dumping Big Insurance requires carefully reviewing your portfolio. You can examine your fund’s prospectus or utilize modern financial research tools to screen for Environmental, Social, and Governance (ESG) criteria. However, divesting from broad market index funds means sacrificing exposure to hundreds of lucrative companies, which can leave your portfolio concentrated and exposed to higher volatility.
Diversifying Outside Traditional Equities
If you decide to shift your capital away from mainstream index funds, financial experts suggest adding non-correlated assets to maintain a balanced portfolio. Two popular alternatives include:
- Precious Metals: Assets like physical gold (often held in a Gold IRA) act as a historical hedge against inflation and market downturns. Their pricing operates independently of corporate profit cycles or insurance claims practices.
- Real Estate-Backed Credit: Alternative funds that invest in short-term loans secured by residential real estate can provide steady income. These property-backed assets offer dividend yields that behave differently than traditional stock market equities.
Frequently Asked Questions (FAQ)
Why does Mark Cuban blame 401(k) investors for high healthcare costs?
Mark Cuban argues that by holding broad index funds, 401(k) investors provide capital to the largest health insurance companies. He believes these companies prioritize shareholder returns over patient care through practices like delaying payments and denying valid claims to earn interest on premium capital.
How can I check if my 401(k) or index fund invests in major health insurers?
You can review your fund’s holdings by reading its prospectus, searching the ticker symbol on major financial data platforms, or checking the fund provider’s official website. Look for top holdings in companies like UnitedHealth Group, CVS Health, and Cigna.
What are the financial risks of divesting from broad market index funds?
Selling your broad index funds to avoid specific sectors reduces your portfolio’s diversification. This can lead to higher volatility and reliance on a narrower segment of the market. Additionally, selling assets in a taxable brokerage account may trigger capital gains taxes.
