Led by Benchmark and EQT Ventures, the fundraise underscores surging investor appetite ​for space infrastructure bets as massive AI computing requirements strain terrestrial energy ​grids and data centre capacity, even as space-based systems offer access ⁠to near-continuous solar power.

Starcloud, which has long-term plans for an 88,000-satellite data centre ​constellation, will use the new capital to fund next-generation satellites, manufacturing expansion and future ​launch contracts as it moves toward commercial operations, it said on Monday.

“The main customer contracts that are committed are for other spacecraft, particularly Earth Observation and DOW satellites. We are also ​working on some binding energy offtake agreements with the hyperscalers to be announced ​in the coming months,” co-founder and CEO Philip Johnston told Reuters.

In February, Elon Musk’s SpaceX acquired ‌his ⁠AI startup xAI and revealed plans for a million-satellite orbital data centre network. Blue Origin, the space venture of Amazon’s Jeff Bezos, has expressed similar ambitions.

Meanwhile, Starcloud is already working with partners including Nvidia and the cloud units of Amazon and Google.

In November, ​it launched a satellite ​carrying Nvidia’s H100 ⁠chip, demonstrating AI training and inference in orbit in an industry-first move.

It now plans a second launch in October featuring Amazon ​Web Services’ AWS Outposts offering.

While space infrastructure would ease power ​and land ⁠constraints, high launch costs remain a challenge. But Starcloud expects them to fall enough by 2028 or 2029 to make space-based data centres cost-competitive with Earth facilities, Johnston ⁠said.

The latest ​round brings Starcloud’s total funding to $200 million, with ​the Redmond, Washington-based company having raised $34 million earlier from investors including Andreessen Horowitz and In-Q-Tel, the Central ​Intelligence Agency’s venture capital firm.
