Bottom line: Panthalassa wants to move a chunk of the AI infrastructure stack off land and into deep water, running neural network workloads on towers that live entirely on wave power and seawater cooling. The company has raised $140 million in Series B funding to move from prototypes into its first commercial hardware. It is effectively betting that open-ocean energy and offshore compute will scale faster than new land-based data centers. The basic concept is straightfoward: generate electricity from waves, use it on the spot, and run AI chips with no connection to the grid. Panthalassa builds autonomous platforms it calls nodes, tall steel structures that sit mostly below the surface and rise and fall with the motion of the sea. Inside, the vertical movement pushes water through an internal turbine, producing electricity in a closed loop.…
