Space Stocks vs SpaceX: Which Has More Growth in 2026?

---

The space industry is gaining more attention as rockets, satellites, and private aerospace companies continue to grow. Investors are watching this sector for long-term opportunities, especially as demand for satellite internet, launch services, and space technology increases.

SpaceX remains the biggest name in the industry, while Rocket Lab offers a public way to invest in space growth today. Both companies have strong potential, but they also come with different risks.

Here are the key differences between SpaceX and Rocket Lab, their 2026 growth potential, and what investors should know before choosing between them.

Why SpaceX Is Leading the Space Industry

SpaceX has become the biggest private space company in the world. The company has grown quickly over the past few years.

Reports estimate SpaceX revenue grew from $2.3 billion in 2021 to $18.5 billion in 2025. That is massive growth in a short period of time.

Most of SpaceX’s money comes from Starlink. Starlink is the company’s satellite internet service that now operates more than 10,000 satellites in low-earth orbit.

As more people and businesses need internet access in remote areas, Starlink continues growing fast.

SpaceX also earns billions from rocket launches. The company works with:

• NASA
• The U.S. Department of Defense
• Telecom companies
• Satellite operators

Another big move was SpaceX acquiring xAI, Elon Musk’s artificial intelligence company behind Grok AI. This gives SpaceX exposure to the growing AI industry as well.

Today, SpaceX has completed more than 600 launches and remains the leader in reusable rocket technology.

How Can I Invest in SpaceX?

Right now, investing directly in SpaceX is difficult because the company is still private.

SpaceX Is Not Public Yet

SpaceX shares are not available on normal stock exchanges. SpaceX, led by Elon Musk, is seeking a public listing at a potential valuation of more than $1.75 trillion. Most shares are owned by Elon Musk, employees, and private investors.

However, many experts believe a SpaceX IPO could happen soon. If that happens, regular investors may finally be able to buy shares through their brokerage accounts.

Ways Investors Try to Get Exposure to SpaceX

✔ Wait for the IPO

This is the easiest option for most investors.

✔ Buy Private Shares

Some wealthy investors buy shares through private markets, but access is limited in many countries.

✔ Invest in Other Space Companies

Many investors who cannot buy SpaceX shares are instead buying public space companies. That is one reason RocketLab stock has become popular with growth investors.

Can Rocket Lab Compete With SpaceX?

Rocket Lab is much smaller than SpaceX, but the company is growing quickly. Rocket Lab focuses on reusable rockets and satellite systems. Its Electron rocket has already completed 85 launches.

The company is also working on a larger rocket called Neutron. This rocket could help Rocket Lab compete more directly with SpaceX in the future.

Rocket Lab is also expanding beyond rockets.

The company now builds:

• Satellites
• Spacecraft parts
• Space systems
• Satellite deployment technology

Its Photon satellite platform is becoming an important part of the business.

Rocket Lab’s revenue has grown fast. The company increased annual revenue from $62 million in 2021 to around $602 million in 2025.

Analysts expect revenue to reach $1.6 billion by 2028. Investors continue watching the rocket lab share price closely because many believe the company still has strong long-term growth potential.

Category	SpaceX	Rocket Lab
Company size	Larger scale	Smaller but growing fast
Profitability	Strong profits	Still focused on future growth
Market position	More market dominance	Competes in a smaller but growing segment
Growth potential	Steady long-term growth	Faster possible growth
Valuation	Higher overall valuation	Smaller rocket lab valuation with more room for growth
Investor access	Limited because it is private	Easier access for public investors

Is Rocket Lab Stock a Better Buy in 2026?

For investors who want exposure to the space industry today, RocketLab stock may currently be the easier option.

Unlike SpaceX, Rocket Lab is already publicly traded. Investors can buy shares using normal brokerage accounts.

Still, investors should understand the risks.

The Rocket Lab's current share price and overall rocket lab share price performance have been volatile because the company is still growing and not yet consistently profitable.

At the same time, Rocket Lab could benefit if:

• Neutron launches successfully
• Demand for satellites increases
• More governments and businesses invest in space technology

Because Rocket Lab is smaller than SpaceX, some investors believe it could deliver larger percentage gains over time.
