Billionaire investor Mark Cuban's stock options philosophy is shining a spotlight on a theme already familiar to ETF investors. Many of the market's biggest wealth creators that are using the option of giving every employee an ownership stake are also the largest holdings in technology-focused funds.

The debate gained fresh momentum after Space Exploration Technologies Corp's SpaceX (SPCX) blockbuster $1.77 trillion IPO reportedly created more than 4,400 employee millionaires, underscoring how equity compensation can generate wealth alongside shareholder returns.

Speaking on the What It Takes podcast, Cuban said he would like "every single CEO, founder, entrepreneur" to give equity to all employees rather than limiting stock awards to senior executives. Drawing on his experience at Broadcast.com, his media company, where he said roughly 300 employees became millionaires after Yahoo acquired the company decades ago, Cuban argued that broad-based employee ownership is one of the most effective ways to reduce income inequality.

He also suggested governments could encourage the practice by offering lower corporate tax rates to companies that distribute equity more broadly. The remarks followed reports that former SpaceX welder Juan Hernandez, who joined the company in 2015 earning $28 an hour, became the owner of an estimated $880,000 worth of SpaceX shares after the company's public debut.

SpaceX's IPO Opens a New ETF Opportunity

For ETF investors, SpaceX's historic listing represents more than just another high-profile IPO. The aerospace giant has become an investable asset through ETFs, allowing investors to gain exposure to one of the world's most valuable companies without owning the stock directly.

Space-focused ETFs are among the earliest beneficiaries. Funds such as ProShares Ultra SpaceX (SPCF) and Tradr 2X Long SpaceX Daily ETF (SPCM) have incorporated SpaceX into portfolios targeting the commercial space economy. As the company becomes more deeply integrated into major equity benchmarks, its weighting is also expected to grow across broader market and sector ETFs, potentially making it a more meaningful holding for mainstream investors over time.

Employee Ownership Is Already Embedded in Major ETF Portfolios

The renewed focus on employee ownership also highlights a common thread among many of the companies that dominate the largest U.S. ETFs.

Technology leaders including Nvidia Corp (NVDA), Microsoft Corp (MSFT), Alphabet Inc (GOOGL), Apple Inc (AAPL), Amazon.com Inc (AMZN), and Broadcom Inc (AVGO) have long relied on stock awards and options to attract and retain talent, creating substantial wealth for employees while rewarding shareholders. These companies also rank among the largest holdings in technology-focused ETFs such as the Invesco QQQ Trust (QQQ), Technology Select Sector SPDR Fund (XLK), and Vanguard Information Technology ETF (VGT).

That overlap is notable because the businesses most associated with broad-based equity compensation have also delivered some of the strongest long-term returns in the public markets. While stock-based compensation can dilute existing shareholders if not managed carefully, proponents argue that giving employees a stake in the company's success aligns incentives, strengthens retention, and encourages long-term value creation.

Academic research lends support to that view. A 2021 Harvard Business School study found that if all private U.S. companies became 30% employee-owned, household wealth would roughly double, while separate studies have linked employee ownership to higher productivity, lower employee turnover, and greater corporate resilience.

For ETF investors, the SpaceX IPO is a reminder that employee ownership is a recurring feature of many of the innovative, market-leading companies that dominate technology and growth-focused ETFs. As SpaceX joins the ranks of publicly traded mega-caps, investors now have another avenue to participate in a business whose success has already created wealth for both employees and shareholders alike.
