SpaceX’s huge IPO has put space stocks back in the spotlight.
The company priced its shares at US$135 each and raised US$75 billion, making it one of the largest listings ever.
Rocket Lab (NASDAQ: RKLB) is benefiting from the excitement because it is one of the clearest listed space stocks investors can already buy.
Rocket Lab also has its own good news: it is being added to the Nasdaq-100 Index before market open on 22 June 2026.
That makes Rocket Lab one of the biggest winners from the space-stock rally, but investors should still be careful about valuation risk.
SpaceX Brings Space Stocks Back Into Focus
SpaceX is set to begin trading on the public market, and investors are paying close attention.
The Elon Musk-led space company priced its IPO at US$135 per share, raising US$75 billion. The company is expected to trade on Nasdaq under the ticker SPCX. The size of the deal has made it one of the biggest IPO stories in market history.
For investors, the important point is simple. SpaceX is not just another new listing. It is the biggest name in private space technology, with businesses across rockets, satellites and Starlink internet.
That is why the IPO is lifting interest across the whole space sector. When a major company lists at a very high valuation, investors often look for other stocks that could benefit from the same theme.
That is where Rocket Lab comes in.
Why Rocket Lab Is Getting Attention
Rocket Lab Corporation (NASDAQ: RKLB) is one of the most obvious public-market ways to invest in the space theme.
Unlike SpaceX, Rocket Lab was already listed. That means investors who wanted space exposure before the SpaceX IPO could buy Rocket Lab shares directly.
Rocket Lab operates in launch services and space systems. In simple terms, it helps send payloads into space and also builds parts, systems and technology used in space missions.
The company is much smaller than SpaceX, but that is also why some investors like it. Smaller companies can sometimes grow faster if demand for their industry keeps rising.
Rocket Lab also got a second boost. The company is being added to the Nasdaq-100 Index before the market opens on 22 June 2026. That is important because many funds and ETFs track the Nasdaq-100. When a stock joins the index, it can get more attention from large investors.
Is Rocket Lab the Biggest Winner?
Rocket Lab may be one of the biggest listed winners from the SpaceX IPO excitement, but investors should separate hype from fundamentals.
The good news is clear. The space industry is getting more investor attention. SpaceX’s listing gives the sector a new benchmark. Rocket Lab’s Nasdaq-100 inclusion also improves its visibility and could increase demand for the stock.
But there are risks too.
First, Rocket Lab is not SpaceX. It does not have SpaceX’s scale, Starlink business or market position. Investors should not assume Rocket Lab deserves the same valuation simply because both companies are in the space sector.
Second, space stocks can be volatile. They often rise quickly when investors are excited, then fall when expectations become too high.
Third, Rocket Lab still needs to prove that it can turn long-term demand into strong and consistent profits. Revenue growth is important, but investors will also want to see margins, cash flow and execution improve over time.
Investor Takeaway
The SpaceX IPO is a major moment for the space economy. It has made investors look again at listed space stocks, and Rocket Lab (NASDAQ: RKLB) is one of the clearest beneficiaries.
The company has two strong short-term catalysts: wider excitement around SpaceX and its upcoming entry into the Nasdaq-100 Index.
That makes Rocket Lab a stock worth watching closely. But it is not a risk-free winner.
For long-term investors, the key question is not whether space is an exciting theme. It clearly is. The real question is whether Rocket Lab can grow into its valuation and build a profitable business over time.
In short, SpaceX has lit the fuse for space stocks. Rocket Lab may be flying higher, but investors should still check the fuel before jumping in.
