Private investment in space startup companies hit an all-time high of $20.8 billion in the third quarter of 2026, nearly triple the previous quarter, as investors backed launch providers, manufacturing and other infrastructure ventures, according to a report by investment firm Seraphim.
Record quarter, by a wide margin
The third-quarter total was nearly triple the $7.4 billion invested in the second quarter and more than double the prior peak, Reuters reported, citing the Seraphim SpaceTech Investment Tracker for Q3 2026. The report counted a record 216 deals, up from 140 in the second quarter. Over the trailing twelve months to the end of September, Seraphim recorded $40.1 billion of investment across 666 deals, compared with $9.7 billion a year earlier.
Not just one mega-deal
A single transaction accounts for a large share of the total: Blue Origin’s $10 billion financing was the quarter’s biggest deal. Even without it, however, investment reached $10.8 billion, which is still an all-time high and points to broad demand across the sector.
Other major rounds included $1.37 billion for Hadrian, $1 billion for Stoke Space and $500 million for K2 Space.
Infrastructure takes the lion’s share
Infrastructure-related businesses accounted for the bulk of the funding. Launch and broader space-access companies attracted $16.4 billion across 120 deals, while satellite communications, Earth observation and other space-service companies raised $4 billion.
Lucas Bishop, vice president at Seraphim Space, said capital is following evidence of commercial and institutional demand, not just leftover enthusiasm from IPOs. He added that defence and sovereign demand increasingly underpin investment in launch, manufacturing and orbital infrastructure as governments prioritise domestic space capabilities.
SpaceX’s shadow and a growing order pipeline
SpaceX remains a dominant force in the industry, but Seraphim said recent fundraising has also been supported by a growing pipeline of commercial orders and government-backed programmes.
Private boom, weaker public markets
The surge in private funding contrasted with weaker performance among listed space companies. Bishop noted that many publicly traded space firms remain loss-making, and that SpaceX’s scale and visibility may have drawn investor attention away from smaller listed peers.
Big cheques, smaller typical deal
The headline figure does not describe the experience of a typical startup. The tracker shows the average deal size rose to $137 million from $72.6 million in the second quarter, while the median deal size fell to $9.8 million from $14.9 million. In other words, a handful of very large rounds pushed the total up, while the typical round got smaller.
Regional picture
North America accounted for about 70% of global funding year to date. China recorded a quarterly high of $3.3 billion across 49 deals.
What comes next
Seraphim said funding is likely to moderate from the third quarter’s exceptional level but remain above historical norms as more companies enter growth and scale-up phases.
