K2 Space Raises $500 Million At $6.8B Valuation To Scale Large, High-Power Satellites

K2 Space has raised $500 million in a Series D round, bringing its valuation to $6.8 billion. This significant increase marks a two-fold rise from its Series C round in December. Co-founder and CEO Karan Kunjur and brother Neel initiated the company four years ago, focusing on the notion that larger satellites would become the trend in space missions, rather than smaller ones.

The company's argument has moved from theory to reality, as evidenced by their Gravitas satellite, which is currently operational with a 20-kilowatt Hall-effect thruster. This satellite's power is intended to demonstrate the feasibility of heavier satellites handling communication and defense missions that smaller platforms can't.

To support this claim, K2 built a state-of-the-art 180,000-square-foot factory in Torrance, capable of producing up to 100 satellites per year, with over 85% of each satellite's platform manufactured within the facility. This strategic move has given investors confidence in K2's ability to scale from a few satellites to dozens or even hundreds without the typical production challenges that other manufacturers face.

The Space Force has selected K2 as a satellite-bus provider for its Protected Tactical Satcom-Global program, making it the company's first Pentagon contract. Commercial satellite operator SES and defense contractor Anduril have also placed orders with K2, with SES requesting 30 satellites for the meoSphere network and Anduril agreeing to construct satellites for the Golden Dome missile-defense program.

K2 currently holds more than $1 billion in signed commercial and government contracts, and the company's next mission includes launching multiple satellites in the second quarter of 2027 and a large 100-kilowatt "Giga-class" satellite in the second half of 2028. Industry experts see K2's valuation as a bet on the infrastructure of the space sector, with Lucas Oliveira from Kleiner Perkins stating that every significant mission in space ultimately revolves around power and mass.

Tengbo Li from ICONIQ general partner emphasizes the belief that space will be one of the defining frontiers of the upcoming century, and K2 is constructing the platform to enable the next generation of the space economy.
