There are five key reasons why SSIT represents an exciting investment case.
1. SSIT is a compelling pure play on the spacetech theme.
The trust is a rare listed pure-play spacetech vehicle, with a portfolio predominantly invested in private growth-stage companies. It represents a viable alternative to ETFs focused on listed large-caps in the aerospace and defence sector and space-enabling technologies, which offer only partial exposure to the theme. Seraphim Space is seeking high-growth businesses that are addressing very large market opportunities that are likely to persist for many decades, providing a long runway of growth and powerful long-term secular tailwinds.
2. Spacetech’s lift-off moment is now.
Commercial space technology is accelerating, driven by a 10x–100x reduction in the cost of access to space. Falling launch costs and the shift to smaller, standardised satellites, such as CubeSats, have significantly reduced manufacturing costs (by around 60%) and compressed development timelines from years to months. By leveraging off-the-shelf components and consumer electronics, universities and startups can now build and deploy satellites faster and more cheaply, lowering barriers to entry and accelerating innovation across the space economy.
This is coupled with growing demand for earth observation from space in end-markets like defence, climate change and insurance, with further demand drivers for spacetech services including connectivity and mobility. According to a report released by the World Economic Forum and McKinsey in 2024, the space economy is predicted to grow from $630bn in 2023 to $1.8tn by 2035. A notable recent illustration of the strong demand for spacetech is the joint venture between Rheinmetall and ICEYE, the trust’s largest portfolio company, aimed at large-scale satellite production in Germany.
Further upside potential is supported by emerging hyperscale catalysts, including the prospect of a SpaceX IPO, which could provide a major public-market liquidity event and valuation reference point for selected parts of the spacetech ecosystem. In parallel, the rapid build-out of AI infrastructure, exemplified by xAI’s Colossus expansion, is reinforcing demand for resilient connectivity, geospatial data, infrastructure monitoring and AI-enabled earth observation analytics, strengthening the role of spacetech within next-generation digital infrastructure.
3. Seraphim Space is made up of pioneers in commercial space technology investments.
Seraphim Space is a pioneer in spacetech investments that has built deep knowledge and deal origination networks. It supported more than 140 companies across its fund management and accelerator activities. Its current team offers a compelling combination of long-term private equity investment expertise with extensive technical and relevant academic and commercial spacetech experience. It is the go-to partner for both spacetech businesses seeking funding and investors searching the sector for attractive private companies to invest in.
4. SSIT offers a portfolio of carefully selected spacetech businesses.
SSIT’s top 10 holdings, which make up the majority of the current portfolio value, represent a diverse set of business models. The largest part of the portfolio value consists of companies operating their own satellite constellations. Its other major holdings pursue a wide range of business models, from data-driven software products and connectivity services using satellite networks to in-orbit services (such as orbital transportation, satellite maintenance and removal) as well as the tracking of space debris using ground-based radars. Collectively, these businesses form the emerging digital infrastructure layer in space, providing the backbone for global communications, Earth observation and the monitoring and security of orbital activity that underpins an increasingly space-dependent modern economy.
5. Spacetech is experiencing sustained investor interest.
Interest of venture capital and growth investors in the spacetech theme remains high. According to the Seraphim Space index, investments in next-generation spacetech businesses increased by 48% y-o-y to an all-time high of $12.4bn in 2025. The high investor interest is illustrated by the fact that Seraphim Space Ventures II, Seraphim’s early-stage venture fund, exceeded its previous target of $100m, with key investors including the British Business Bank and The National Security Strategic Investment Fund as well as leading international defence and space industry players. Several portfolio holdings of the trust completed new funding rounds in recent months, including D-Orbit’s first close of its €110m Series D round. Furthermore, HawkEye 360, a space-based radio frequency intelligence and geospatial analytics firm and a portfolio company of the trust, recently filed for an IPO on the New York Stock Exchange at an estimated fully diluted equity valuation of more than $2bn.
Seraphim’s broader ecosystem strengthens its origination capability. The Seraphim Space Accelerator identifies early-stage category leaders in spacetech, providing access to emerging technologies and founding teams at the earliest stage. Together with its venture funds, this creates a multi-stage pipeline from incubation through to growth capital, enhancing potential deal flow into listed exposure via SSIT.
