Defense and energy technology startup Antares has secured a $470 million Series C funding round to accelerate the commercialization of its advanced power systems for military installations.
Jordan Bramble announced the funding, noting the round was co-led by Paradigm and Caffeinated Capital [1]. The capital injection also saw participation from Point72 Ventures, Industrious Ventures, Balerion Space Ventures, Shine Capital, and 53 Stations.
The Series C round brings the company’s total research and development investment to approximately $1 billion, pushing the firm toward commercial scale [1]. The funding follows Antares reaching “criticality” and successfully fielding power systems designed for defense applications.
The massive capital influx highlights the growing strategic importance of energy resilience within the defense sector. As military installations increasingly require independent, secure, and continuous power sources, venture capital is aggressively backing companies capable of delivering microreactor and advanced energy technologies at scale.
The investment positions Antares to expand its footprint across military infrastructure, directly addressing the Department of Defense’s stated need for resilient power generation that can operate independently of vulnerable civilian grids.
