Spacetech funding hit new heights in 2025
The spacetech industry is going from strength to strength, and spacetech funding has hit new heights. Investment in the spacetech sector reached $3.8 billion in Q4 2025, and $12.4 billion across the entirety of 2025, beating the previous 2021 peak, which stands at $12.2 billion.
The sector has fully bounced back from the 2022 downturn in investment. This financial backing underscores the sector’s growing importance across defence, communications, and next-gen infrastructure. Unlike the investment peak the industry saw in 2021, which was driven by a handful of oversized rounds, the last year’s momentum has come from a wider base of growth-stage companies. Deal flow has broadened, capital is spreading across the ecosystem, and investor conviction in core space infrastructure has solidified.
This data from global space investment firm Seraphim Space, revealed that the $3.8 billion raised in Q4 of 2025 was a record period of space investment.
Investment focus
In terms of where the money was going, late-stage investments (Series D and above) increased nearly 40% year-on-year, while Series B and C continued to dominate total capital deployment.
The largest raises of Q4 highlight the deepening focus on capital-intensive, core space-infrastructure companies, particularly in the launch sector.
Stoke Space raised a $510 million Series D round, which was the single largest raise of the period. The US based launch company is building fully reusable rockets and has emerged as one of the sector’s most closely watched late stage players. Its round reflects the growing belief that new entrants capable of competing with or complementing SpaceX will be central to the next decade of orbital access.
Castelion, another US launch company, secured $350 million in a Series B round, marking an unusually large raise for an earlier stage spacetech company. This highlights the appetite for next-gen rocket manufacturers, and the readiness of investors to back startups earlier in their maturity curve if they are able to demonstrate clear technical differentiation and address strategic national security needs.
China’s Space Pioneer raised a $350 million Series D+. The rise continues a broader pattern: China’s increasing investment in LEO constellations, satellite production, and homegrown launch systems as it seeks greater autonomy in space.
These three deals show how launch has become the centre of spacetech investment.
The top 10 deals accounted for $2.4 billion of all Q4 activity, well over half of the total quarterly investment.
Location analysis
The United States has cemented its position as the global centre of spacetech, attracting a total of $7.3 billion in 2025, making up around 60% of all funding. Growth was propelled by advances in launch systems, defence driven initiatives such as Golden Dome, and the expanding role of space based infrastructure in national security.
Europe recorded steady gains, supported by rising defence budgets and a renewed drive for sovereign capabilities as governments seek greater independence in space systems.
Asia remained a major force, with China contributing around $2 billion and continuing to scale up satellite manufacturing, launch vehicles, and LEO constellations at pace.
Commenting on the results, Lucas Bishop, Investment analyst at Seraphim Space, said: “2025 was a landmark year for spacetech, setting all time highs both quarterly and over the past twelve months, fully recovering from the 2022 downturn and outpacing the broader VC market. The entire sector is entering an extraordinary stage, with investment surging into core segments like Build, Launch, and Downlink, driven by strategic geopolitical dynamics including the US Golden Dome initiative, rising European defence spending, and China’s accelerating domestic programmes.
“Looking ahead into 2026, a number of reinforcing trends are likely to drive spacetech investment even higher. First, we expect the geopolitical dynamics that underpinned investment momentum in 2025 to continue, with space being increasingly seen by governments as a strategic priority, sustaining funding across sovereign satellite constellations, communication systems, and orbital ISR. Second, we see AI integration accelerating across space systems, enabling autonomous constellations and real-time analytics. Finally, a potential SpaceX IPO could act as a powerful catalyst, validating spacetech as a mainstream asset class and opening the door for a wave of public-market listings.”
