With SpaceX expected to complete its initial public offering (IPO) this month, many investors are asking a simple question: Will I own SpaceX in my mutual funds and ETFs?
The answer is: it depends on the index your fund follows.
Recent changes by some index providers have made it easier for large newly public companies to enter certain indices shortly after their IPOs.
For investors, three questions matter most:
- Will SpaceX be included in the index my fund tracks?
- How much SpaceX will I own?
- Could heavy demand push the stock price higher?
Will SpaceX Be Included?
Most mutual funds and ETFs either track or are benchmarked to market indices such as the Russell 1000, NASDAQ-100, or S&P 500.
NASDAQ and FTSE Russell have updated their methodologies to allow certain large IPOs to enter applicable indices relatively quickly. As a result, investors in Russell- and NASDAQ-based funds may gain exposure to SpaceX soon after the IPO.
The S&P 500 takes a different approach. Companies generally must trade publicly for at least twelve months and meet specific float, liquidity, and profitability requirements before they can be considered. Consequently, SpaceX is unlikely to appear in S&P 500 index funds immediately and may not become eligible until 2027 or later.
How Much SpaceX Will You Own?
Many investors assume that because SpaceX is one of the world’s largest companies by estimated market value, it will immediately become a major holding in their funds. In reality, the initial exposure may be surprisingly small.
The reason is public float—the percentage of shares available for public trading. While SpaceX’s total market value may rank among the largest public companies, only a small percentage of shares are expected to be available to investors initially. Most shares will remain held by founders, employees, and early investors.
Index weights are generally based on publicly available shares rather than total shares outstanding. As a result, SpaceX’s initial weight in most broad-market indices is expected to be far smaller than its headline valuation would suggest. Investors may gain exposure quickly, but the position is unlikely to have a significant impact on overall portfolio performance.
Could Demand Push the Stock Price Higher?
Possibly.
SpaceX’s IPO is expected to attract tremendous investor interest while only a limited number of shares will be available for trading. At the same time, index funds that track applicable Russell and NASDAQ indices may become automatic buyers once the stock is added.
When substantial demand meets limited supply, prices can be pushed higher than they otherwise would be. This dynamic has occurred with other highly anticipated IPOs, where enthusiasm, media attention, and institutional buying contributed to sharp price swings.
Over time, however, additional shares often become available as lockup periods expire and early investors are allowed to sell. Increased supply can help moderate prices and reduce some of the initial volatility.
Bottom Line
If you own a Russell- or NASDAQ-based index fund, there is a good chance you will gain exposure to SpaceX relatively soon after the IPO. If you primarily own S&P 500 index funds, you may have to wait much longer.
Funds likely to own SpaceX within the first few months of trading include:
- iShares Russell 1000 ETF
- iShares Russell 1000 Growth ETF
- Schwab 1000 Index Fund
- Invesco QQQ Trust
Funds tracking S&P indices that are unlikely to own SpaceX initially until profitability and seasoning thresholds are met include:
- iShares S&P 100 ETF
- iShares Core S&P 500 Fund
- State Street SPDR S&P 500 ETF
The more important point is that despite SpaceX’s enormous size and visibility, its initial weight in most diversified portfolios is likely to be relatively modest. Investors who maintain diversified portfolios will likely gain exposure naturally over time—without needing to rush out and buy the stock directly.
