The impending initial public offering of Space Exploration Technologies Corp. — better known as SpaceX — has gripped global capital markets this week, on track to become one of the most historic listings on record. The company is set to raise roughly $75 billion and command a $1.8 trillion market capitalization, a staggering valuation that has unleashed unprecedented investor hype.
Yet for all the fanfare, market history suggests piling into the stock on its debut is far from a sure bet. A research report from Truist, which analyzed 30 major tech IPOs in recent years, found that every single one suffered a significant drawdown within its first year of public trading. The challenge is compounded by the fact that the SpaceX offering is already two times oversubscribed, putting shares at the issue price out of reach for most retail investors. Chasing the stock once it begins trading carries substantial near-term volatility risk; a more prudent strategy is to wait for the almost inevitable post-listing pullback until valuations revert to more justifiable levels.
Even so, investors eager to tap into the fast-expanding space economy have no shortage of already-public alternatives — many of which stand to get a lift from the broader sector enthusiasm SpaceX’s IPO is generating. McKinsey estimates the global space economy will swell from roughly $630 billion in 2023 to $1.8 trillion by 2035, laying the groundwork for sustained long-term growth across the entire value chain.
A core player in the commercial launch segment, Rocket Lab began with small-scale missions but has expanded rapidly in recent years. Its operations now span launch services, control systems for space and defense applications, and full-spectrum spacecraft design, engineering and manufacturing.
With a market capitalization of about $66 billion, the company posted 38% revenue growth last year to $602 million. Consensus projections put earnings growth at 56% for 2026, and the stock has already climbed roughly 50% year to date.
Planet Labs operates a large-scale satellite constellation that captures regular imagery of Earth’s surface, serving a diverse customer base ranging from government agencies to agricultural operators that depend on consistent data feeds.
At around $10.5 billion in market value, it is a smaller name in the space sector, but one with striking price momentum: shares surged eightfold over the past 12 months. The stock pulled back modestly after its first-quarter earnings release, even as results came in solid — they simply fell short of the market’s lofty expectations. That dip creates an attractive entry point for investors looking to buy on weakness.
As a critical supplier of propulsion engines for heavy-lift space vehicles, L3Harris holds an entrenched position in the space supply chain. It further strengthened its space division in 2023 via the acquisition of Aerojet Rocketdyne.
Shares are up 24% over the past year, but retreated following the company’s first-quarter results earlier this year. While quarterly revenue and profit growth came in strong, its forward earnings guidance was viewed as underwhelming by the market. Even so, its strategic positioning in a fast-growing sector remains firmly intact.
For investors who prefer broad sector exposure over picking individual stocks, exchange-traded funds offer a lower-risk avenue to capture the space economy’s growth. The ARK Space Exploration & Innovation ETF (ARKX), managed by Cathie Wood’s Ark Invest, stands out as a leading actively managed option in the space.
The fund targets multi-decade technological shifts — what Ark dubs “innovation platforms” — with a five-year investment horizon, and allocates at least 80% of its assets to space and defense innovation equities. Boasting roughly $893 million in net assets, ARKX has returned about 12% so far in 2026 and 46% over the past 52 weeks. With holdings across at least 35 individual stocks, it delivers wide diversification, giving investors single-ticket access to a broad swath of the space and defense landscape.
As SpaceX’s blockbuster IPO continues to shine a spotlight on the final frontier, investors do not need to chase a frothy debut to participate in the industry’s upside. Between pure-play launch operators, specialized satellite firms, established defense suppliers and diversified thematic funds, there are multiple pathways to capture long-term value as the global space economy scales up over the coming decade.
