Vast Raises $500M as Space Startups Attract Billions in 2026

A New Space Race, Bankrolled by Private Fortunes

Private capital is pouring into space ventures at a pace that would have seemed implausible even a decade ago. California-based Vast, a startup building commercial space stations, has secured a $500 million funding round led by Jed McCaleb, the crypto billionaire best known for co-founding Ripple and Stellar 14. The deal, closed in August 2026, underscores a broader shift: space exploration, once the near-exclusive province of national governments, is increasingly being shaped by private money chasing the next frontier of infrastructure and industry 1.

Vast's Ambitions and Growing Pains

Vast's pitch centers on replacing the International Space Station, which is nearing the end of its operational life, with commercially built and operated orbital outposts 5. The $500 million infusion positions the company as one of the best-capitalized players racing to fill that vacuum, with McCaleb's backing seen as a signal that outside investors, not just aerospace veterans, view low-Earth-orbit infrastructure as a viable long-term bet 14. Yet the funding has not translated into unchecked expansion. Despite the massive raise, Vast recently cut 46 jobs, roughly 4% of its workforce, even as it pushes ahead with its space station timeline 5. The layoffs suggest that even flush startups in this sector are managing costs carefully as they scale toward the technically demanding, capital-intensive work of building habitable structures in orbit.

Space Tourism and Orbital Real Estate

Beyond space stations, the broader narrative coverage frames Vast's raise as part of a larger transformation in how people think about living and working beyond Earth. Orbital hotels, manufacturing platforms, and permanent human settlements are no longer confined to speculative fiction but are being discussed as emerging, multi-billion-dollar market categories 4. Vast's funding round is presented as a bellwether for this space tourism and habitation boom, with McCaleb's involvement lending crypto-world credibility and capital to an industry traditionally dominated by aerospace contractors and government budgets 14.

AI Workloads Push Into Orbit

Space-based investment isn't limited to habitation. Starcloud, a separate startup, is developing satellites packed with high-performance GPUs, including NVIDIA hardware, to run artificial intelligence workloads directly in orbit 2. The company recently raised $250 million at a $2.3 billion valuation, aiming to expand AI infrastructure through orbital data centers capable of delivering up to 20 gigawatts of computing capacity 23. That valuation jump reflects investor enthusiasm partly fueled by SpaceX's high-profile IPO, which appears to have reinvigorated broader interest in commercial space plays 3.

What the Momentum Signals

Taken together, the flurry of nine- and ten-figure raises across station-builders and orbital data-center developers suggests investors increasingly see space not as a scientific curiosity but as a platform for tangible commercial infrastructure, from tourism and manufacturing to computing. Whether these valuations hold up will depend on execution: Vast's job cuts amid record funding hint that even well-capitalized companies face real operational discipline as they attempt to turn orbital ambition into working hardware.
