Texas Startup Last Energy Raises $100 Million for Mini Nuclear Reactors Powering AI

Texas startup Last Energy has raised $100 million to build and deploy mini nuclear reactors for AI data centers. The company plans modular units that deliver steady, carbon-free power near compute clusters. The funding backs factory production, site development, and customer agreements aimed at round-the-clock reliability as data center demand surges. Power-hungry AI training strains grids, and companies seek cleaner supply. Last Energy pitches shorter build times, standardized components, and predictable costs compared with large nuclear plants. The company targets private power deals that bypass grid bottlenecks and match data center load. Contracts would supply dedicated, on-site power to new global server farms. Investors are betting that next-generation nuclear can anchor the next wave of AI growth across markets
