Muon Space raises $250M Series C with Google and Salesforce Ventures at reported $1.5B valuation
What's the deal? Satellite startup Muon Space closed a $250 million Series C round in August 2026, backed by Alphabet's Google and Salesforce Ventures. While Muon declined to comment on its valuation, SpaceNews reported that the round valued the company at $1.5 billion. The company raised the capital after launching 11 satellites into orbit and opening a manufacturing facility in California.
Why now? The round follows two operational milestones: getting satellites into orbit and standing up its own manufacturing base. That combination gives investors evidence the company can build and deploy hardware at scale.
What's the endgame? Muon Space builds and operates satellites, using the hardware and the data it collects. The new capital and its California facility position it to expand production and grow its constellation.
The signal: At $250 million, this is among the largest Series C rounds ever in US big data — landing in the 99th percentile across 713 comparable deals. The reported $1.5 billion valuation places Muon among the latest space companies to reach unicorn status, while backing from major technology and institutional investors signals sustained appetite for companies pairing space hardware with data at scale.
