The space economy has captured the spotlight this year, primarily driven by the highly anticipated initial public offering (IPO) of Space Exploration Technologies (NASDAQ: SPCX), better known as SpaceX. On June 12, the company made history with the largest initial public offering ever and closed the day with a valuation of around $2.1 trillion, putting it in the company of some of the world's largest companies.
That said, SpaceX doesn't have nearly the revenue of those behemoths and trades at an expensive valuation that prices in massive future growth, making the stock vulnerable to huge price swings. If you're an investor looking for exposure to the rapidly expanding space economy, here are two space stocks that are better buys before piling into SpaceX.

Rocket Lab's business spans the space ecosystem
Rocket Lab (NASDAQ: RKLB) is the biggest competitor to SpaceX's launch business and the second-most-used launch platform in the United States today. Over the past year and a half, Rocket Lab has made 35 launches, dwarfed by SpaceX's 260 over the same period. That said, Rocket Lab has carved out a niche with its small-lift Electron rocket, which enables it to serve small to medium-sized satellite customers.
Because its Electron rocket can carry payloads of only around 300 kilograms (660 lbs), Rocket Lab cannot currently carry large payloads into space like SpaceX can with its Falcon 9. However, its small rocket provides its customers with greater flexibility and control over the timeline while also enabling precise placement of these smaller satellites into orbit.
In addition, Rocket Lab has developed the Hypersonic Accelerator Suborbital Test Electron (HASTE), a launch platform specifically designed for defense and national security purposes. The advantage of HASTE is that it provides the government with high-cadence, cost-effective testing for hypersonic and suborbital payloads as the Pentagon evaluates various defense technologies. In March, Rocket Lab secured a $190 million contract to conduct 20 hypersonic test flights for its HASTE launch vehicle.
Rocket Lab's launch services business continues to grow steadily, but the company has another avenue for growth through its space systems business. Here, Rocket Lab designs and manufactures a wide range of space components and technologies, such as satellite buses, reaction wheels, star trackers, solar panels, separation systems, radios, and software. Of its $2.2 billion backlog, $1.3 billion is related to its space systems segment.
SpaceX also owns xAI and other technology businesses, where it is pegging most of its future growth. For investors looking for a more pure-play space stock, Rocket Lab's end-to-end space business spans multiple verticals, and the company has made major acquisitions in recent years to expand its role in the space ecosystem.
Lockheed Martin is a prime contractor for NASA's Orion program
Lockheed Martin (NYSE: LMT) is a massive defense contractor, with sales from aeronautics (notably its F-35 fighter jets and other military aircraft), missiles, rocket systems, and helicopters, as well as a growing space business. For investors seeking exposure to a more stable stock with ties to the space economy, Lockheed Martin is appealing.
The company's broad portfolio and position in the defense industry provide it with a strong competitive moat and a platform that translates into stable, long-term revenue. Its F-35 program is projected to generate $2.1 trillion over its 94-year lifecycle (from 1994 to 2088) and is a major part of its business, providing stability and buffering its earnings against recessions and economic volatility.
However, its space segment is another key growth driver for its wide-ranging business. Here, Lockheed develops missile-warning satellites, GPS satellites, classified spacecraft, and next-generation missile defense systems. In addition, Lockheed Martin is the prime contractor for NASA's Orion spacecraft, responsible for designing, building, and assembling the capsule that will take astronauts to the Moon and beyond.
Compared with SpaceX, Lockheed offers investors a more diversified business that benefits from recurring revenue from decades-long space programs, providing direct exposure to growing U.S. and allied spending on space infrastructure and to soaring defense spending amid geopolitical uncertainty.
On top of that, the company trades at a far lower multiple and pays a solid dividend yielding 2.7%, which it has grown every year for the past 23 years. For more conservative investors seeking exposure to the growing space economy, Lockheed Martin is an excellent stock to buy today.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again
In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. If you'd invested $5,000 then, you'd be sitting on $2,633,375 today.*
Now, for the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. It's a key player in the $1.8 trillion space race, and with the stock recently sitting 20% off its highs, the window to get in early is closing fast.

Four leading AI models discuss this article
"The article overstates the 'buy before SpaceX' opportunity; both names carry material execution and competitive risks that are downplayed relative to their current valuations."
The article positions RKLB and LMT as safer, cheaper alternatives to the frothy post-IPO SpaceX (SPCX). RKLB's $2.2B backlog and dual launch/systems model look attractive, while LMT offers diversified defense revenue, Orion exposure, 2.7% yield and far lower multiples. However, the piece glosses over execution risk: RKLB has yet to scale beyond small-lift Electron (35 launches vs SpaceX's 260), its Neutron medium-lift vehicle remains unproven and cash-burn continues. LMT's space segment is real but dwarfed by F-35; its valuation already prices in decades of stable cash flows. Missing context: launch market is winner-take-most; SpaceX's Starship cadence and reusability edge could commoditize small-satellite rideshares faster than acknowledged.
Both stocks could materially underperform if SpaceX executes Starship at scale, collapsing launch prices and margins across the board; RKLB's niche then evaporates and LMT's slower-moving programs lose relative appeal to pure-play growth investors.
"The article's central premise is built on a hallucinated SpaceX IPO, invalidating the comparative valuation analysis provided."
The article contains a major factual error: SpaceX is not a publicly traded company on the NASDAQ under ticker 'SPCX', nor did it have a $2.1 trillion IPO on June 12. This renders the comparison fundamentally flawed. Rocket Lab (RKLB) is a high-beta growth play, but its path to profitability remains obscured by heavy R&D spending on the Neutron rocket, which is essential to compete with Falcon 9. Lockheed Martin (LMT) is a stable dividend payer, but it is primarily a defense prime contractor, not a 'pure-play' space stock. Investors should view LMT as a geopolitical hedge, not a high-growth space vehicle, and exercise extreme caution given the misinformation regarding SpaceX's market status.
If the reader ignores the erroneous SpaceX IPO claim, the core argument holds that RKLB offers high-growth optionality in small-sat launch, while LMT provides the necessary cash-flow stability to weather the high-risk, capital-intensive nature of the space sector.
"RKLB and LMT are not apples-to-apples alternatives to SpaceX; they solve different problems and carry different risks, and the article obscures this by bundling them as 'safer space exposure.'"
The article's framing is backwards. It warns SpaceX is 'expensive' at $2.1T valuation with low revenue, then pitches RKLB and LMT as safer alternatives. But RKLB trades at ~8x sales with minimal profitability—arguably pricier on fundamentals. LMT is genuinely cheaper (12x forward P/E, 2.7% yield), but calling it a 'space play' is misleading; 80%+ of revenue is defense/aeronautics. The real issue: the article conflates three different risk profiles without acknowledging that SpaceX's valuation may be justified by Starship's addressable market ($500B+/year if fully operational), while RKLB's niche (small-lift) faces structural headwinds as SpaceX's Falcon 9 costs drop and Starship scales.
SpaceX's $2.1T valuation could be a genuine bubble if Starship development stalls, regulatory hurdles intensify, or competition from Blue Origin/Chinese providers accelerates faster than expected. RKLB's $1.3B space systems backlog sounds solid until you realize satellite bus commoditization and defense budget uncertainty could compress margins.
"SpaceX’s rumored $2T IPO valuation is highly speculative and should not be treated as a reliable signal for buying RKLB or LMT without clear, scalable cash flows and defense-spend visibility."
The article leans on SpaceX IPO hype to frame RKLB and LMT as safer space bets. But SpaceX is private; there's no verifiable public SPCX data, and a $2.1T valuation would require cash-flow unrealistically outsized relative to current revenue. Even if SpaceX IPOs, the multiple would be vulnerable to policy shifts and the fragility of a near-term revenue model. RKLB’s growth hinges on small-payload launches and defense-linked programs; cash flow is choppier than the headline backlog suggests. LMT offers diversification and a dividend, yet space is a minor contributor to earnings. The piece glosses execution, competition, and regime risk in space and defense spending.
If SpaceX does IPO and proves cash-generative through Starlink monetization and government contracts, a large multiple might be justified; the article's skepticism could overlook potential monetization streams.
"Starship's reusability edge risks rendering RKLB's small-lift niche unprofitable faster than any backlog can offset."
Gemini's factual correction on the nonexistent SPCX IPO is correct and undercuts the entire article premise. Yet the panel still treats RKLB's Neutron timeline and backlog conversion as credible without addressing that Starship's marginal cost near zero could collapse small-lift pricing before Neutron flies. LMT's F-35 dominance doesn't protect its modest space margins from this commoditization wave.
"RKLB's valuation is better justified as a satellite component manufacturer than as a pure-play launch provider."
Claude correctly identifies that RKLB's 8x sales multiple is fundamentally expensive, yet we are ignoring the 'Space Systems' pivot. RKLB is evolving into a component supplier for the entire industry, not just a launch provider. If they capture the satellite bus market, they become the 'Intel Inside' of space. The risk isn't just Starship pricing; it's whether RKLB can scale manufacturing fast enough to survive the transition before their cash runway hits zero.
"RKLB's Space Systems rebranding doesn't change the fundamental cash-burn timeline or address Starship's structural cost advantage."
Gemini's 'Intel Inside' pivot is clever but unsubstantiated. RKLB's Space Systems revenue is ~$40M annually against $2.2B backlog claims—mostly launch contracts, not component supply. Show me a signed satellite bus OEM deal or manufacturing capacity expansion. Until then, this is aspirational storytelling masking that RKLB still burns cash on Neutron while Starship's marginal economics erode their core launch margin. The pivot doesn't solve the timing problem.
"RKLB's Space Systems pivot is speculative; without signed satellite-bus contracts, it won't meaningfully de-risk cash burn."
Claude's critique of RKLB's pivots to Space Systems is fair, but it overlooks why the pivot matters: even a modest, signed satellite-bus deal would diversify revenue away from cash-burning launches. The bigger flaw is treating this as proven; RKLB has yet to demonstrate scale in Space Systems, and backlog conversion relies on multi-year contracts amid a commoditizing launch market. Until signing, the pivot remains speculative, not substantiated by cash-flow support.
The panel consensus is that Rocket Lab (RKLB) and Lockheed Martin (LMT) are not safer alternatives to SpaceX, despite the article's framing. RKLB's high valuation, cash burn, and reliance on small-lift launches are concerning, while LMT's space segment is dwarfed by its defense business. The key risk is SpaceX's Starship commoditizing small-lift launches, threatening both RKLB's and LMT's space margins.
