Starcloud Raises $250M for Orbital Data Centers
Starcloud, a startup building satellites for AI inference in orbit, added a $250 million extension to its March $170 million Series A, valuing the company at $2.3 billion. The funding will scale manufacturing and advance its largest spacecraft, Starcloud-3, which is intended to fly on SpaceX’s Starship. Investors in the extension include Manhattan West Ventures, Nvidia (reported $25M), Cisco, Benchmark, EQT and others. Starcloud plans rideshare launches of two 8 kW compute satellites (Starcloud-2) in 2027, has requested FCC permission to operate 88,000 spacecraft, and is building a 100,000 sq ft production facility in Woodinville, Washington. The company is collaborating with Nvidia on space-ready GPU development and aims to fly Nvidia’s Vera Rubin Space-1 chip in late 2028.
Significant funding and Nvidia participation validate nascent space-based AI compute, but constrained and uncertain launch capacity limits near-term scale; important for AI infrastructure but not directly adtech industry-shifting.

Starcloud raises $170M to build space data centers
Starcloud, a space-compute startup and Y Combinator alum, closed a $170 million Series A led by Benchmark and EQT Ventures at a $1.1 billion valuation. The company has raised $200 million to date and launched its first satellite carrying an Nvidia H100 GPU in November 2025. Starcloud plans a more powerful Starcloud 2 satellite later this year (multiple GPUs including an Nvidia Blackwell chip and an AWS server blade) and is designing a Starcloud 3 orbital data-center spacecraft sized for SpaceX’s Starship (200 kW, three tons). CEO and founder Philip Johnston expects cost-competitive orbital data centers if commercial launch costs reach ~$500/kg, but wider competitiveness depends on Starship achieving operational cadence (commercial access forecast 2028–2029). The company cites technical challenges including power generation, cooling, and synchronization across many GPUs; competitors include Aetherflux, Google’s Project Suncatcher, Aethero and SpaceX itself.
AI Data Centers Moving to Space
This newsletter deep-dive examines the growing case for orbital AI data centers, tracking technical arguments, commercial milestones and remaining engineering challenges. The author interviewed Starcloud founder/CEO Philip Johnston, who says Starcloud launched Starcloud-1 (a 60 kg satellite carrying an Nvidia H100) and ran what the company describes as first in-orbit model training and high-powered inference. Proponents (Gavin Baker, major hyperscalers) highlight abundant solar power and radiative cooling potential in space; skeptics point to Stefan–Boltzmann limits and large radiator-area requirements (e.g., ~1.1 m² per H100). Starcloud plans a follow-up launch in October 2026 carrying Blackwell-generation GPUs and optical terminals. The piece concludes inference workloads are the near-term opportunity while full-scale training remains constrained by interconnect, data transfer and economics, and that falling launch costs and deployable radiators could make orbital compute viable within 5–10 years.
SpaceX Advances Orbiting AI Data Centers Ahead of IPO
SpaceX executives including CEO Elon Musk and COO/President Gwynne Shotwell outlined plans to position the company as a provider of AI infrastructure in orbit ahead of its planned IPO. Engineers (including Ian Dahl) described design concepts for solar-powered AI satellites using radiative cooling and a simpler form factor than existing Starlink units. The first prototype satellite is expected to deliver ~150 kW peak and ~120 kW sustained compute — roughly comparable to a single Nvidia GB300 server rack. SpaceX says Starship’s full reusability will enable transporting large volumes of solar panels, radiators and chips to orbit. Production at a new AI-satellite factory in Bastrop, Texas aims to reach meaningful volumes by the end of 2027. The company’s IPO is planned imminently, targeting ~555.6 million shares at $135 and an implied market value of about $1.75 trillion.
