Peter Thiel Leads $140 Million Round for Panthalassa’s Wave-Powered Offshore AI

The plan shifts the challenge from delivering offshore power to sending small data outputs by satellite.

Overview

  • Panthalassa closed a $140 million Series B led by Peter Thiel on Monday, bringing its disclosed funding to $210 million.
  • The startup’s floating nodes turn wave-driven motion into electricity inside a closed hydraulic loop that spins internal turbines.
  • Each node houses AI servers cooled by surrounding seawater and returns results via low‑Earth‑orbit satellites rather than shore cables.
  • New funding will help finish a pilot manufacturing facility near Portland as the company readies Ocean‑3 hardware for field use.
  • Ocean‑3 pilots are scheduled for the northern Pacific in 2026 with commercial deployments targeted for 2027, though experts flag bandwidth limits, harsh-sea durability, and maintenance as key risks.
