Peter Thiel Leads $140 Million Panthalassa Round — Ai News

Peter Thiel led ai news of Panthalassa’s $140 million funding round earlier this month. The U.S.-based startup is betting on floating data centers that sit on the ocean and use seawater cooling, which could ease pressure on electricity-constrained data center builds.

The funding pushed Panthalassa’s valuation close to $1 billion, according to the Financial Times. That scale gives the company more room to keep building a hardware-heavy system that has spent years in prototype work rather than software-style iteration.

Panthalassa started designing its Ocean-1 and Ocean-2 prototypes in 2021. The company’s nodes sit on top of the ocean with nearly 280-foot-long steel structures extending below the surface, and each one holds a hermetically sealed AI server cooled by surrounding seawater.

Ocean-3 in the Pacific

The company plans to deploy its Ocean-3 system in the northern Pacific Ocean this year. Commercial deployment is expected to follow in 2027, so the round appears aimed at turning a long design cycle into an actual operating fleet.

Garth Sheldon-Coulson, Panthalassa’s cofounder and CEO, said, “We’ve built a technology platform that operates in the planet’s most energy-dense wave regions, far from shore, and turns that resource into reliable clean power. We’re now ready to build factories, deploy fleets, and provide a sustainable new source of energy for humanity.”

Compute, power, and scale

Thiel said, “The future demands more compute than we can imagine.” He also said, “Extra-terrestrial solutions are no longer science fiction. Panthalassa has opened the ocean frontier.”

The appeal is straightforward for operators chasing new compute capacity. Wood Mackenzie noted earlier this year that data center development had slowed down because electricity capacity growth has lagged, and Panthalassa is selling an escape route built around the open ocean rather than the grid.

Sheldon-Coulson said, “There are three sources of energy on the planet with tens of terawatts of new capacity potential: solar, nuclear, and the open ocean.” The harder question is whether the engineering and offshore logistics can match that ambition at commercial scale by 2027.
