Valar Atomics raises $1B to mass-produce nuclear reactors for AI data centers

The nuclear industry's traditional bottleneck—capital intensity and long deployment timelines—is being directly targeted by AI operators desperate for reliable baseload power. Valar's $1B round signals that venture capital now views small modular reactors (SMRs) as infrastructure, not speculative tech. This creates a bifurcation in energy markets where hyperscalers bypass grid politics entirely, potentially stranding existing utility assets while concentrating geopolitical leverage over nuclear fuel supply chains among a handful of AI firms.
