$1 billion has now been committed to a rocket that has never reached orbit. Stoke Space closed an initial Series E tranche on September 8, lifting total capital raised to $2.3 billion and pushing its first orbital launch target to early 2027.
The company is betting a liquid-hydrogen-cooled metallic heat shield, rated for 100 reuses, reaches a cost floor that partially reusable rockets cannot.
The first commercial unlock is national security launch. Nova must fly successfully before it can compete for Space Force task orders.
The round was co-led by Point72 Ventures and Spark Capital, with General Innovation, Glade Brook Capital, US Innovation Technology, Washington Harbour Partners, Woven Capital and Y Combinator participating. It did not disclose a valuation.
Capital has run ahead of the hardware before in this market, though rarely by this margin. Rocket Lab had raised about $148 million when it closed its Series D in March 2017. Its Electron rocket reached orbit the following January.

🔥 NEXT: Nova Pathfinder first orbital launch, early 2027
Funding rounds from company disclosures, SpaceNews and Payload reporting, 2021-2026.
The company has raised roughly $2.1 billion since January 2025. That covers a $260 million Series C, a $510 million Series D, a $350 million extension to that round, and the initial Series E. None of it has bought a completed orbital mission yet.
Capital raised to date
The Series E funds manufacturing, test, launch and recovery infrastructure for the Nova line. It has not yet produced an orbital flight. · Company disclosures, 2026
The vehicle is where the money is meant to show up. Nova Pathfinder carries a liquid-hydrogen-cooled metallic heat shield that it says will support 100 reuses. In a fully reusable configuration it is designed to lift 3,000 kilograms to low Earth orbit (LEO). Expended, that figure rises to 7,000 kilograms.
Nova Pathfinder payload capacity
The expendable configuration lifts 7,000 kilograms. The reusable figure is the one that matters for the cost argument. · Payload, 2026
Testing scaled up while the rocket waited
Hardware work continued in parallel with fundraising. The company wrapped proto-qualification of Pathfinder's first stage in June, running it through 46 structural tests at its Moses Lake facility in Washington state. The test site is expanding from 75 acres to 550 acres to support both Pathfinder and the larger vehicle.
The company is also finishing a rebuild of Launch Complex 14 at Cape Canaveral, the pad that sent John Glenn to orbit in 1962. The concrete is nearly ready. What it lacks is a rocket.
Hardware is the constraint.
| Metric | Stoke Space (2026) | Rocket Lab (2017) |
|---|---|---|
| Capital raised before first orbital launch | $2.3B | $148M |
| First orbital launch | early 2027, target | January 2018 |
| Reusability approach | fully reusable, planned | expendable first stage |
The historical contrast is the point. Rocket Lab reached orbit on a fraction of the capital. It is attempting a harder problem. Its heat shield must survive reentry repeatedly, and its upper stage must return as well, not only the booster.
Every mature transportation system is built around fully reusable vehicles. It's the only way to reach the cost floor while scaling availability.— Andy Lapsa, co-founder and CEO, Stoke Space
The Series E also funds a second vehicle. Nova Block 2 will deliver 15 metric tons to LEO inside a 5-meter payload fairing, with a first launch targeted for 2029. The design has been in development in parallel for years, the company says, rather than drawn up for the announcement.
What changes with the larger Nova Block 2?
The first customer is the government
It joined the Space Force's National Security Space Launch (NSSL) Phase 3 Lane 1 pool in March 2025. Inclusion reserves a place, not a contract. The company cannot compete for task orders until Nova flies successfully. In July, the Space Force tripled the Lane 1 ceiling to $17 billion, expanding the program to roughly 170 expected missions.
Space Force launch contract pool
The ceiling was tripled in July 2026 across roughly 170 expected missions. It cannot bid until Nova flies. · Payload, 2026
What does it take to win a task order?
The turning points that matter
The first is clean orbital insertion. Nova Pathfinder is designed to carry payloads to orbit while proving the core architecture. A successful debut converts that place into bidding rights and gives customers a second fully reusable option beyond the incumbent.
The second is reflight. It plans multiple Pathfinder missions through 2027 and 2028, building flight data while Nova Block 2 takes shape. A heat shield rated for 100 reuses means little until the same hardware flies twice.
Full reusability is the inevitable end state of the market, providing an order-of-magnitude cost and service advantage over partially reusable rockets.— Clay Fisher, General Partner, Spark Capital
What the raise actually prices
The round is a wager on cost curves, not schedules. Point72 and Spark Capital both backed it at its 2021 Series A and returned for every round since. Their conviction rests on the view that reuse, rather than cadence, decides who wins the next decade of launch. The argument is that a fully reusable stack reaches a cost floor that a reusable booster alone cannot.
The schedule has already moved once. Pathfinder slipped from late 2026 to early 2027, and the company's own roadmap now stretches multiple test flights across two years. As we wrote in September, satellite manufacturers are racing to catch constellation demand. Each of those satellites still needs a ride, and the supply of proven, reusable lift remains thin.
Whether the capital arrived early or simply arrived patient is now a question of test cadence. It has the money, the pad, and the launch window. The next eighteen months decide what the $2.3 billion bought.
