Seraphim Space Investment Trust plc (LSE:SSIT) will be promoted to the FTSE 250 Index from the start of trading on 19 June 2026, marking a major milestone for the specialist SpaceTech investor following the latest FTSE UK Indices Annual Review.
The move comes nearly five years after the company’s IPO and reflects the continued expansion of its portfolio, growing investor appetite for the SpaceTech sector and the successful £137 million C share fundraising completed recently. Entry into the FTSE 250 is expected to raise the trust’s profile among institutional investors, while also benefiting from increased index-related demand and improved share liquidity.
FTSE 250 inclusion highlights growth of SpaceTech platform
The promotion underlines the progress made by Seraphim Space as it has grown into one of the leading listed investors focused exclusively on the global space technology sector. The company believes its new index status will broaden its investor base and further support long-term growth ambitions.
Will Whitehorn OBE, Chair of Seraphim Space Investment Trust plc, commented:
“Our inclusion in the FTSE 250 marks a significant milestone for Seraphim Space Investment Trust and is a clear reflection of the progress we have made in scaling the Company over the last five years and demonstrating the attractiveness of SpaceTech as an institutional asset class. We believe this inclusion will further enhance the Company’s visibility, improve liquidity and support continued growth in our shareholder base.”
Space increasingly viewed as critical infrastructure
Mark Boggett, Chief Executive Officer of Seraphim Space Manager LLP, said the promotion reflects both the company’s evolution and the growing strategic importance of the space sector.
“SSIT joining the FTSE 250 reflects not only the Company’s progress, but the transition of space from a specialist technology theme into a core pillar of global infrastructure. Space has become foundational to how nations operate, compete and secure their future.
The convergence of defence, sovereign capability and data infrastructure is redefining the market, with governments globally investing in resilient space architectures for security, communications and intelligence. This is driving a structural shift where demand is long-term, procurement is strategically funded and commercial innovators are now embedded at the heart of national security systems. As the only listed investment company offering diversified access to this largely privately backed ecosystem, SSIT is uniquely positioned to participate in, and help shape, this next phase of growth.”
The FTSE 250 promotion represents another step forward for Seraphim Space as it seeks to capitalise on increasing institutional interest in a sector that is becoming ever more closely linked to defence, communications, data infrastructure and national security priorities worldwide.
