Vast Space
Vast builds commercial space stations, aiming to replace the ISS with Haven-1 and Haven-2.
On the record
Checkpoint: NASA Commercial LEO Destinations Phase 2 contract award
The call
Vast has flown real hardware and secured government backing, but its future rests on a 2027 launch and a contract decision it does not control.
Vast Space designs and plans to launch commercial space stations that companies and governments can use in orbit. The challenge is that Vast has not yet launched or flown a station and is racing against competitors like Axiom Space and Sierra Space who are further along. Vast did test hardware in November 2025 and has backing from NASA and other governments, which is real progress, but the company's future largely comes down to two big unknowns in 2027: whether its first station launches successfully and whether NASA picks Vast for a major long-term contract that would fund the next station.
Why
01
AI pressure: None apparent. Space station hardware and orbital habitats sit outside where AI models or agents currently compete. Could AI do the core job? Unlikely.
02
Bigger players: Axiom Space, Sierra Space, and Starlab (Voyager/Airbus/Lockheed). Axiom has flown four private astronaut missions and Sierra Space is valued near $8B, both racing for the same NASA station contract. Could a giant copy it? Yes, easily.
03
What protects it. Real flight heritage from the Haven Demo mission plus NASA, France, UK, and ESA agreements that rivals without flown hardware cannot yet match.
What would change this call
NASA awards Commercial LEO Destinations Phase 2 contracts, spring 2027. Shows whether Vast secures long-term government revenue or loses out to Axiom/Sierra/Starlab.
Haven-1 launch attempt in Q1 2027. Tests whether Vast can deliver flight hardware on schedule versus further slippage.
Vast's sixth NASA PAM mission to ISS, targeted summer 2027. Confirms whether Vast can execute crewed missions independent of Axiom.

Key numbers
- $500M Series A plus $200M debt raised
- Haven Demo launched Nov 2025, deorbited Feb 2026
- First non-Axiom NASA private astronaut mission awarded
Named risks
- Haven-1 launch has already slipped from 2025/mid-2026 to Q1 2027.
- NASA CLD Phase 2 contract award (spring 2027) not guaranteed, could go to Axiom, Sierra Space, or Starlab.
- Conflicting valuation and funding figures across reports ($500M vs $250M rounds, $2B vs $5.5B valuations).
- 2024 California wrongful-retaliation complaint from former engineer remains unresolved reputational overhang.
- Well-capitalized rivals (Axiom, Sierra Space) racing same 2027-2030 milestones with more operational proof.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Axiom Space | losing to | Axiom has flown 4 crewed PAMs and holds firm-fixed-price NASA contract as of June 2025; Vast's Haven-1 unflown |
| Axiom Space | gaining on | Vast won first non-Axiom NASA PAM award Feb 12, 2026, ending Axiom's monopoly |
| Sierra Space | losing to | Sierra Space raised $550M at $8B valuation March 5, 2026, above Vast's disclosed figures |
| Starlab Space | contesting | Starlab touts single-launch Starship 400 m3 station design with Hilton, Northrop Grumman partners, per March 2026 report |
| Blue Origin/Sierra Space Orbital Reef | gaining on | Orbital Reef reportedly only completed early design review milestones as of March 2026, behind Vast's flown Haven Demo |
Questions people ask
- Is Vast Space profitable?
- No public revenue or profit figures exist. Vast is pre-revenue in the sense that its flagship Haven-1 station has not yet launched; a Q1 2027 Falcon 9 launch is targeted as of March 2026, so meaningful revenue would follow that milestone.
- Will Vast Space's Haven-1 station launch on schedule?
- Haven-1 was originally targeted for 2025 or mid-2026 but slipped to Q1 2027 on a Falcon 9 after additional NASA environmental testing, per a March 9, 2026 report. Primary structure completed January 2026, so integration is underway but timeline has already moved twice.
- Who owns Vast Space?
- Vast is privately held. Founder Jed McCaleb, who started the company in 2021, remains chairman and its largest investor as of July 2026. CEO Max Haot took over operational leadership in 2023 after Vast acquired his company Launcher.
- Is Axiom Space Vast Space's biggest competitor?
- Yes, Axiom is the most advanced rival: it has flown four private astronaut missions to the ISS, including Axiom-4 in June 2025 with Peggy Whitson commanding, and holds a firm-fixed-price NASA contract, while Vast's Haven-1 has not yet flown.
- Could AI replace what Vast Space does?
- No. Vast's business is physical spacecraft manufacturing, human-rated safety certification, and government contracting, none of which generative AI automates. NASA certification, flight hardware, and international government MOUs signed in June 2026 are relationship and regulatory moats, not software tasks.
- How much funding has Vast Space raised?
- Vast announced $500M in new financing on March 5, 2026 ($300M Series A equity plus $200M debt, led by Balerion Space Ventures), stating cumulative investment exceeded $1 billion. A later report described an a16z-led $250M round valuing the company at $5.5B, unconfirmed by primary sources as of July 2026.
