Muon Space Raises $250M Series C at $1.5B Valuation

Satellite-constellation developer Muon Space has raised $250 million in a Series C funding round as it looks to expand manufacturing capacity amid growing demand for space-based infrastructure.

The round was led by Eclipse Capital, with participation from Google, Salesforce Ventures and Wellington Management. The latest investment brings Muon Space's total equity funding to more than $386 million.

The company was valued at $1.5 billion in the latest round, according to a source familiar with the matter.

Muon Space is developing satellite constellations designed to support applications including Earth observation, secure communications and orbital computing. Rising demand from governments and businesses for space-based infrastructure has increased the need for larger satellite networks and faster deployment capabilities.

The company launched seven satellites during the first half of 2026, bringing its total number of deployed satellites to 11 across six launches. Muon says it has maintained a 100% mission success record.

CEO Jonny Dyer said the company's existing backlog is currently more commercial than government-focused, although government demand is growing rapidly. He expects the company's U.S. government and commercial business to be roughly evenly split within the next couple of years.

Muon has also been expanding its manufacturing capabilities. The company recently opened a facility in San Jose designed to produce up to 500 satellites annually by 2027.

The new factory comes as Muon works through a backlog of more than 50 satellites currently in development for customers. The company has launch contracts extending through 2029 covering existing and planned missions.

Muon is also pursuing additional launch capacity beyond SpaceX to reduce its reliance on rideshare missions and provide greater flexibility as its satellite production scales.

Much of the new funding will be directed toward expanding the workforce and building out infrastructure at the San Jose manufacturing facility.

The company is considering a potential public listing as early as 2027, although Dyer said an IPO next year is unlikely because Muon needs greater visibility into future revenue before going public.

The latest funding highlights the increasing investor interest in satellite infrastructure as space-based services become more important for commercial and government applications. For Muon Space, the immediate challenge will be turning its growing backlog and manufacturing capacity into a larger deployed constellation while maintaining its mission success record.
