Stoke Space Technologies Secures $860M in Extended Series D Funding for Reusable Rocket Development

Rockets do not care about hype. They care about physics, cash flow, and whether your math survives gravity. Stoke Space just raised another $510M in Series D funding, later extended to $860M, and suddenly the conversation shifts from ambition to inevitability.

Andy Lapsa, Co Founder and CEO of Stoke Space, is not pitching sci fi. He is building Nova, a 100% reusable medium lift rocket designed to make space access routine instead of ceremonial. That word reusable gets thrown around a lot in this industry. Stoke Space is chasing full reuse, including the upper stage. That is the hard part. That is where economics either break down or break through.

This $510M Series D round was led by Thomas Tull’s U.S. Innovative Technology Fund, with Washington Harbour Partners and General Innovation Capital stepping in, and existing investors like 776, Breakthrough Energy, Glade Brook Capital, and Toyota Ventures doubling down. When that caliber of capital lines up, it is not charity. It is conviction.

Rewind the tape. In October 2023, Stoke Space announced a $100M Series B led by Industrious Ventures, bringing total funding to $175M. In January 2025, a $260M Series C pushed total funding to $480M, backed by names like Breakthrough Energy Ventures, Glade Brook Capital Partners, Industrious Ventures, Leitmotif, Point72 Ventures, Seven Seven Six, University of Michigan, Woven Capital, and Y Combinator. Now with the full Series D, total funding sits around $1.34B. That is not a funding story. That is a war chest.

But money is just oxygen. What matters is what you do with it. Stoke Space is building toward Launch Complex 14 at Cape Canaveral Space Force Station, turning historic ground into a launchpad for Nova. The mission is ultra low cost, on demand transportation to and from space. Not once in a while. Not when the stars align. On demand.

Here is the business lesson hiding in plain sight. Stoke Space kept stacking credible milestones before stacking massive rounds. Each raise more than doubled prior totals. Each round pulled in sharper capital. They did not sell a dream. They sold progress. Investors responded accordingly.

The space economy does not need another PowerPoint. It needs reliable lift capacity that makes new markets possible. If Nova delivers on full reuse, margins change. Launch cadence changes. Entire downstream industries start modeling differently.
