Peter Thiel backs $140M floating AI data center startup Panthalassa

Silicon Valley investors including Palantir co-founder Peter Thiel have poured hundreds of millions into Panthalassa, a startup deploying wave-powered AI data centers on the ocean. The latest $140 million round, announced May 4, will fund a pilot manufacturing facility near Portland, Oregon, and accelerate production of floating "nodes" that generate electricity from waves to directly power onboard AI chips. Instead of transmitting renewable energy to land-based data centers, these nodes send inference tokens—outputs from AI models—to customers via satellite. Benjamin Lee, a computer architect at the University of Pennsylvania, noted the approach transforms an energy transmission problem into a data transmission problem. The investment comes as tech companies face mounting challenges building AI data centers on land.
