In this article, we take a look at the 10 Fastest-Growing Space Stocks to Buy Now.
The public space market remains a developing area for investors, but the underlying industry has continued to expand. According to Space Foundation, the global space economy reached a record $613 billion in 2024, up 7.8% year over year, with commercial activity accounting for most of the total. More recent satellite data also points to continued demand. The Satellite Industry Association (SIA) reported that 2025 saw 325 launches, including 296 commercially procured satellite launches, while commercial launch revenue rose 33% to $12.4 billion.
Satellite services have also continued to grow, helped by broadband and remote sensing demand. SIA said global satellite broadband subscribers increased 62% to more than 10 million in 2025, while broadband revenue rose 16%. BryceTech separately reported that nearly 2,800 small satellites were launched in 2024, representing 97% of all spacecraft launched that year. These figures give investors a useful backdrop for public companies tied to launch services, satellite manufacturing, Earth observation, space infrastructure, and direct-to-device communications. Still, many space stocks remain early-stage, unprofitable, or dependent on contract timing, so strong revenue growth does not remove execution and funding risks.

10. Planet Labs PBC (NYSE:PL)
Planet Labs PBC (NYSE:PL) is one of the fastest-growing space stocks to buy now. On June 4, Planet Labs secured two National Geospatial-Intelligence Agency milestones, including a one-year, $22 million extension under the Luno B IDIQ contract for AI-enabled Maritime Domain Awareness and a new Global Monitoring Service award with NGA and the Defense Innovation Unit. The awards strengthen the growth case because they show demand from the government moving beyond satellite imagery into recurring analytics, change detection, and crisis-response monitoring, areas where Planet can sell higher-value services from its existing constellation and data archive.
That demand is already showing in the numbers. Also on June 4, Planet reported fiscal first-quarter 2027 revenue of $94.2 million, up 42% year over year, while backlog rose 72% to more than $906 million and remaining performance obligations increased 81% to $816 million. For a space company still working toward steadier profitability, the key point is that revenue growth is being supported by contract visibility, not only future satellite ambition.
Planet Labs PBC (NYSE:PL) provides global daily satellite imagery, geospatial data, analytics, and software solutions for government and commercial customers.
9. Firefly Aerospace Inc. (NASDAQ:FLY)
Firefly Aerospace Inc. (NASDAQ:FLY) is one of the fastest-growing space stocks to buy now. On May 26, Firefly said it won a $75 million subcontract from NASA’s JPL to deliver four drones to the Moon’s south pole for the MoonFall mission, targeted for launch no earlier than 2028. The award fits the growth theme because it adds another funded lunar mission to Firefly’s spacecraft backlog and extends the role of its Elytra vehicle beyond transport into deployment support for NASA’s Moon Base initiative.
The update also connects with the company’s first-quarter growth. On May 4, Firefly reported Q1 2026 revenue of $80.9 million, up about 45% from $55.9 million a year earlier, while reaffirming full-year revenue guidance of $420 million to $450 million. The quarter included progress across Blue Ghost lunar missions, Alpha Flight 7, and national-security programs, showing why Firefly’s growth story is spread across lunar infrastructure, launch, and space-defense work rather than a single project.
Firefly Aerospace Inc. (NASDAQ:FLY) is a space and defense technology company that provides launch vehicles, lunar landers, orbital vehicles, and related space systems for government and commercial customers.
8. Karman Holdings Inc. (NYSE:KRMN)
Karman Holdings Inc. (NYSE:KRMN), which operates as Karman Space & Defense, is one of the fastest-growing space stocks to buy now. On May 29, Karman said its active pipeline had reached about $3 billion as of May 25, compared with about $1 billion as of March 31, 2025. The company also said it had secured or was negotiating several opportunities, including a space-launch production long-term agreement with an estimated value of about $250 million.
That pipeline gives context to Karman’s recent revenue growth. On May 12, the company reported first-quarter 2026 revenue of $151.2 million, up 51.0% year over year, while backlog reached $1.0 billion, up 61% from the prior-year quarter. Space and Launch revenue rose 29.5% to $43.9 million, helped by orders supporting legacy and emerging launch providers and spacecraft. Karman also raised its 2026 revenue outlook to $720 million to $735 million, showing how current demand is feeding into a larger growth base.
Karman Holdings Inc. (NYSE:KRMN), through Karman Space & Defense, provides payload protection, interstage, propulsion, launch, and other mission-critical systems for space and defense programs.
7. Redwire Corporation (NYSE:RDW)
Redwire Corporation (NYSE:RDW) is one of the fastest-growing space stocks to buy now. On June 4, Redwire said it won a contract from Astrobiome Space to launch its first space agriculture mission using Redwire’s Greenhouse system on the International Space Station, described as the world’s first commercial space greenhouse. The mission will grow strawberries and test Astrobiome’s soil-enhancement product, giving Redwire another customer use case for microgravity research and life-support technologies. For this growth screen, the relevance is less about the undisclosed contract size and more about how the award extends Redwire’s infrastructure base into commercial biological research.
The award sits on top of a stronger first-quarter growth profile. On May 6, Redwire reported first-quarter 2026 revenue of $97.0 million, up 57.9% year over year, with a record backlog of $498.1 million and a 1.92 book-to-bill ratio. Gross margin improved to 26.6%, although the company remained unprofitable. The growth case is tied to rising contract activity across space infrastructure and microgravity research.
Redwire Corporation (NYSE:RDW) is an integrated space and defense technology company that provides space infrastructure, autonomous systems, microgravity research platforms, deployable structures, sensors, and related mission-critical technologies.
6. Rocket Lab USA, Inc. (NASDAQ:RKLB)
Rocket Lab USA, Inc. (NASDAQ:RKLB) is one of the fastest-growing space stocks to buy now. On May 22, Rocket Lab completed its ninth dedicated Electron launch for Synspective, deploying another StriX synthetic aperture radar satellite and expanding the Japanese company’s Earth-observation constellation. Rocket Lab said another 18 Synspective launches are booked, making the update relevant to the growth screen because it points to repeat commercial demand rather than a one-off mission.
The launch cadence also sits alongside Rocket Lab’s broader push into higher-value space systems. On May 26, the company completed its acquisition of Motiv Space Systems, now Rocket Lab Robotics, adding Mars-proven robotic arms, actuators, and precision mechanisms used on missions including NASA’s Perseverance rover and CADRE lunar rovers. The additions support planetary exploration, constellations, and orbital infrastructure. On May 7, Rocket Lab reported first-quarter 2026 revenue of $200.3 million, up 63.5% year over year, with backlog above $2.2 billion, showing growth across launch services and space systems.
Rocket Lab USA, Inc. (NASDAQ:RKLB) provides launch services, spacecraft, satellite components, solar solutions, spacecraft software, and related space systems for commercial, civil, and exploration customers.
