SpaceX has officially joined the Nasdaq-100, marking a significant milestone just weeks after its blockbuster initial public offering (IPO). The move places Elon Musk’s space company alongside some of the world’s largest technology firms and is expected to trigger billions of dollars in automatic buying by index-tracking funds.

For investors, the inclusion means SpaceX will become part of many popular exchange-traded funds (ETFs), potentially boosting demand for its shares. Here’s what the move means and why it matters.

What is the Nasdaq-100?

The Nasdaq-100 is one of the world’s most closely watched stock market indexes. It tracks the 100 largest non-financial companies listed on the Nasdaq Stock Market.

The index is heavily weighted toward technology and growth companies, including firms involved in artificial intelligence, software, semiconductors, cloud computing, biotechnology, and digital services.

Because many mutual funds and ETFs mirror the Nasdaq-100, companies added to the index often experience increased investor demand.

Why was SpaceX added so quickly?

SpaceX became eligible after completing its IPO on June 12.

Previously, newly public companies generally had to wait at least three months before joining the Nasdaq-100. Earlier this year, Nasdaq revised its rules, allowing qualifying companies to enter the index as soon as 15 days after their public listing.

Market experts say the rule change was partly designed to accommodate exceptionally large IPOs.

Peter Haynes, head of index and market structure research at TD Securities, told CNN that index providers updated their methodologies because of the unprecedented size of the SpaceX listing.

What does joining the Nasdaq-100 mean for investors?

The biggest impact comes from passive investing.

Hundreds of investment funds and ETFs are designed to replicate the Nasdaq-100. Once a company joins the index, those funds must purchase its shares to maintain the correct portfolio allocation.

This creates automatic demand for the newly added stock.

Potential effects include:

• Increased buying from index funds.
• Higher trading volumes.
• Greater visibility among institutional investors.
• Inclusion in popular Nasdaq-100 ETFs.

Investors who already own Nasdaq-100 index funds will now indirectly own SpaceX shares without making an additional investment.

Will SpaceX become one of the largest companies in the index?

Not immediately.

Although SpaceX’s overall valuation reportedly exceeds $2 trillion, index weighting depends largely on the number of shares available for public trading, known as the free float.

Since SpaceX sold less than 5% of its shares during its IPO, only a relatively small portion of the company is available on the public market.

As a result, its initial weighting in the Nasdaq-100 is expected to be modest.

If additional shares become publicly tradable in the future, SpaceX’s influence within the index could grow.

How has SpaceX stock performed since its IPO?

SpaceX debuted at $150 per share.

The stock quickly climbed to approximately $225 before pulling back.

Ahead of its Nasdaq-100 inclusion, shares were trading around $160, remaining above their IPO price but below their early post-listing highs.

Like many newly listed companies, the stock has experienced significant volatility as investors evaluate its valuation and long-term growth prospects.

What should investors watch next?

Several events could influence SpaceX’s stock over the coming months.

First earnings report

Investors are awaiting the company’s first quarterly earnings as a publicly traded business, expected later this summer.

The report will provide insight into revenue growth, profitability, Starlink performance, launch services, and future guidance.

Lock-up expiration

Following most IPOs, insiders are prohibited from selling shares for a set period.

Once the lock-up expires, employees, founders, and early investors may begin selling stock.

An increase in available shares could:

• Improve liquidity.
• Increase market volatility.
• Potentially affect the stock price.

Index weighting

If more shares enter public circulation over time, SpaceX’s weighting in the Nasdaq-100 could increase, giving it greater influence over the index’s overall performance.

Can SpaceX join the S&P 500?

Not yet.

Unlike Nasdaq, the S&P Dow Jones Indices have not shortened their eligibility requirements.

To qualify for the S&P 500, SpaceX must generally:

• Be publicly traded for at least one year.
• Meet minimum market capitalization and liquidity requirements.
• Report four consecutive quarters of positive earnings under S&P’s profitability criteria.

Even if those conditions are met, inclusion is ultimately determined by the S&P Index Committee.

What are analysts saying?

Several analysts remain optimistic about SpaceX’s long-term prospects.

Wedbush has initiated coverage with an “Outperform” rating and a price target of $190 per share.

Goldman Sachs has highlighted the company’s growth opportunities across satellite communications, launch services, and artificial intelligence infrastructure.

Analysts at Deutsche Bank have also pointed to SpaceX’s potential advantages in deploying AI-related computing infrastructure alongside its expanding space business.

What does this mean for the broader market?

SpaceX’s inclusion reinforces the growing influence of technology companies in major U.S. stock indexes.

For investors, it means:

• Nasdaq-100 ETFs now include exposure to SpaceX.
• Passive funds will continue purchasing shares as required by index rules.
• The company’s financial performance will increasingly affect index returns.
• SpaceX could become an even larger market force if its public float expands over time.

For now, investors are expected to focus on the company’s first earnings report, insider share sales after lock-up periods end, and whether SpaceX can justify its lofty valuation as a newly public company.
