Vast raises $500M to build the ISS's commercial successor

What's the deal? Vast, a Long Beach, California-based space station startup, has raised $500 million — $300 million in equity and $200 million in debt — to accelerate development of its commercial space stations.

Why now? Vast is racing toward a 2027 launch of Haven-1, intended to be the world's first commercial space station. It also just won a NASADealroom has a profile for this one.

The timing is pointed. The ISS is expected to retire around 2030, and NASA is preparing to hand off low-Earth orbit operations to private companies through its Commercial Low Earth Orbit Destinations programme. Vast wants to be the one holding the keys.

What could go wrong? The commercial space station business is still largely theoretical. Vast's chief executive Max HaotDealroom has a profile for this one. Try Dealroom → has been candid that his financial model assumes close to zero revenue from emerging markets like space manufacturing or pharmaceutical research in the next five years — the company is betting almost entirely on NASA and allied space agencies as customers. That makes it highly dependent on government contracts that have yet to be finalised.

NASA has also been slow to release the final procurement for the next phase of its commercial station programme, and political uncertainty around the agency's direction adds further risk. A delayed RFP means a delayed path to revenue.

The signal: Money is flowing fast into the commercial space station race. Rival Axiom Space raised $350 million less than a month before Vast's round — and notably, Qatar's sovereign wealth fund backed both.

That kind of institutional, cross-border capital entering the sector signals that investors are starting to treat low-Earth orbit infrastructure as a serious long-term asset class, not a moonshot bet. The ISS has a retirement date. Someone has to replace it — and investors are placing their chips early.
