Muon Space raises $250 million at $1.5 billion valuation to scale satellite production

Muon Space raised $250 million in a Series C round led by Eclipse Capital at a $1.5 billion valuation to scale satellite production, bringing total equity funding to over $386 million. The company has more than 50 customer satellites in development, with 13 manifested for launch over the next year, and its San Jose facility aims to produce up to 500 satellites annually by 2027.

The round was led by Eclipse Capital and values the Mountain View, California-based company at $1.5 billion, according to a person familiar with the transaction. 5 https://finance.yahoo.com/technology/articles/satellite-maker-muon-space-valued-143324210.html The financing brings Muon’s total equity funding to more than $386 million. Google, Salesforce Ventures, Wellington Management, I Squared Capital, Galvanize and Woven Capital joined the round, alongside existing backers including Radical Ventures, Congruent Ventures, Costanoa Ventures, Activate Capital, ACME Capital, ArcTern Ventures and Overlap Holdings. 6 https://finance.yahoo.com/technology/articles/muon-space-closes-250-million-110000717.html A larger production target Muon said the new capital will support production of large-scale constellations, expanded dual-use spacecraft platforms and capabilities including advanced payloads, on-orbit AI computing and high-bandwidth satellite connectivity developed with SpaceX’s Starlink network. The company did not disclose how much of the round is allocated to each program. 7 https://finance.yahoo.com/technology/articles/muon-space-closes-250-million-110000717.html The immediate manufacturing target is Muon’s San Jose production center. The company opened the 130,000-square-foot facility in June 2026 after moving into the site the prior year. It says the center can support production of as many as 500 satellites per year by 2027, across spacecraft in the roughly 100-kilogram to 500-kilogram-plus class. 8 https://www.nbcbayarea.com/news/local/satellite-manufacturing-facility-san-jose/4102889/ That target is well above Muon’s current operating base. Seven satellites launched during the first half of 2026, bringing the company’s deployed total to 11 spacecraft across six launches, according to Muon. The company said all 11 missions have succeeded. 9 https://finance.yahoo.com/technology/articles/muon-space-closes-250-million-110000717.html Customers provide the near-term workload Muon says more than 50 customer satellites are now in development, with 13 already manifested for launch during the coming year. Those figures describe projects in development and launch planning, not a disclosed dollar-value backlog. Muon has not published revenue or profitability figures for the business. 10 https://starpath.global/news/muon-space-raises-250-million-to-scale-satellite-constellation-production/ Two of its most visible programs are moving toward operations. Vindlér 2.0, developed for Sierra Nevada Corp. — which is the customer and service operator — uses three Muon-built satellites to collect and analyze radio-frequency data. The spacecraft launched March 30, 2026, and entered commissioning after initial contact. 11 https://www.sncorp.com/news-archive/snc-and-muon-space-launch-three-vindl%C3%A9r-20-satellites-to-power-expedited-rf-data-analytics/ Muon is also building FireSat with the nonprofit Earth Fire Alliance and Google Research. Three additional FireSat satellites launched in July 2026, following an earlier demonstration spacecraft. Google says the constellation is designed to detect fires as small as 5 by 5 meters and eventually provide global updates every 20 minutes, although the full network is still being deployed. 12 https://blog.google/innovation-and-ai/models-and-research/google-research/firesat-satellites/ Other disclosed customers include Hubble Network, which selected Muon’s larger MuSat XL platform for a satellite-enabled Bluetooth network, and Hydrosat, which contracted with Muon for a spacecraft carrying multispectral and thermal-infrared instruments for agricultural and climate data. 13 https://www.muonspace.com/press/muon-space-unveils-xl-satellite-platform-announces-hubble-network-as-first-customer From Halo to larger spacecraft Muon’s platform strategy began with Halo, an integrated system that combines spacecraft, payloads, software and mission services. In April 2024, the company announced more than $60 million in contracts covering 10 Halo spacecraft ranging from 150 kilograms to 500 kilograms, with launch and operations included. 14 https://www.muonspace.com/press/muon-space-redefines-leo-satellite-constellations-with-the-release-of-muon-halo-tm The company expanded its Series B to $146 million in June 2025, combining $44.5 million in equity with $45 million in credit facilities. That financing supported the new manufacturing facility, the acquisition of propulsion startup Starlight Engines and efforts to bring propulsion, instruments and constellation operations further inside the company. 15 https://www.prnewswire.com/news-releases/muon-space-completes-146-million-series-b-to-scale-satellite-constellations-for-defense-and-commercial-missions-302479524.html Muon has since added larger platforms to its product line. Its MuSat XL spacecraft is a 500-kilogram-class platform, while Condor-Ultra is aimed at constellations ranging from hundreds to thousands of spacecraft and is designed for higher-power sensing, communications and orbital-computing missions. 16 https://www.muonspace.com/newsroom The financing gives Muon more room to standardize those platforms, but the production goal remains an execution challenge. Moving from 11 deployed satellites to a 500-per-year manufacturing cadence requires repeatable supply chains, testing processes, launch access and customer demand. Muon has disclosed the size of its development pipeline and launch manifest, but not the detailed economics of the new production line.
