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.
Methodology
For this article, we screened publicly listed space companies and selected stocks with the highest year-over-year revenue growth rates. Companies with unusually high growth but severe balance sheet or operating concerns were not considered for the list.

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.
