Space startups raised approximately $7.5 billion across 141 venture deals in the second quarter of 2026, just shy of the record $8 billion across 159 deals set in Q1 -- making the first half of 2026 the strongest six-month period the space economy has ever recorded, even as the sector's most visible public proof point wobbles.
Spacecraft manufacturers pulled in the largest share of that capital: $2.36 billion across 26 deals over the trailing 12 months, or roughly 43% of total sector funding, as investors increasingly favor companies with proven, scaling hardware over earlier-stage bets on unproven technology. Investors named across the quarter's larger rounds include backers of Stoke Space, K2 Space, Sierra Space, Vast, and Isar Aerospace -- companies with flight heritage or near-term launch manifests rather than pure R&D roadmaps.
“SpaceX went public June 12 at roughly a $1.77 trillion valuation, the largest IPO in history, raising $75 billion.”
The divergence worth watching sits in public markets. SpaceX went public June 12 at roughly a $1.77 trillion valuation, the largest IPO in history, raising $75 billion. The stock peaked above $225 before sliding to trade close to 39% below that high, now hovering near its original $135 offering price -- a round trip that has wiped a substantial chunk of paper gains for IPO-day buyers in barely six weeks.
That private funding held its pace through SpaceX's public stumble is the more interesting data point. It suggests venture investors are underwriting individual companies on their own execution and contracts -- launch manifests, government payloads, in-space servicing deals -- rather than simply riding a SpaceX-driven halo effect into every space-adjacent pitch deck. If SpaceX's public volatility were dragging private valuations down in sympathy, Q2's numbers would look weaker, not near-record.
What to watch: whether Q3 private funding holds if SpaceX's stock continues to slide, and whether any of the well-capitalized private players (Vast, Isar, Stoke) use the moment to accelerate toward their own public listings while public investors are still willing to underwrite hard-tech space bets.
