What Panthalassa does
Panthalassa is a public-benefit corporation, founded around 2016 and headquartered in the Portland, Oregon area, that builds autonomous floating platforms which convert ocean wave motion into electricity to power onboard AI inference computing hardware. The company's product line centers on its "Node" architecture: a self-propelled floating platform using a closed hydraulic loop to extract wave energy, with sealed compute modules housed below the waterline that use natural seawater cooling in place of freshwater systems. Connectivity between ocean-deployed nodes and land-based customers is delivered through SpaceX's Starlink satellite network, eliminating the need for anchors, cables, fuel, or grid interconnection. The current portfolio consists of the Ocean-2 prototype — a 70-meter steel tower generating up to one megawatt, deployed off the Washington coast since 2025 — and the Ocean-3 commercial series of approximately 85-meter nodes targeted for northern Pacific pilot deployment in 2026 and commercial deployment in 2027.
The company's commercial model is a usage-based AI compute service sold directly to AI companies and hyperscalers facing grid capacity, cooling water, and permitting constraints on terrestrial data centers, with secondary optionality in supplying wave-generated power to third-party maritime or coastal operators. Pricing is not publicly disclosed; the company has claimed a target power cost of $0.02/kWh, though third-party analysts have disputed this figure on operational grounds. The company is pre-revenue, with cumulative funding of approximately $210 million across a $140 million Series B led by Peter Thiel in May 2026 and prior private funding from AI companies, and a post-money valuation close to $1 billion.
Panthalassa's go-to-market combines an enterprise field-sales motion targeting large AI operators with a direct, satellite-mediated delivery model that bypasses terrestrial distribution. It maintains a content-driven marketing presence (corporate website, YouTube, LinkedIn, X) and has received earned-media coverage in Business Wire, GeekWire, Forbes, and TechRadar. Engineering and operations staff are concentrated in Portland and Vancouver, Washington, with active hiring across naval architecture, GNC, fluid dynamics, structural engineering, computational engineering, and offshore marine operations, and fleet operations planned for international waters in the northern Pacific.

Revenue model
- AI Compute Services at Sea: Providing AI inference computing infrastructure on autonomous floating nodes. AI companies purchase access to compute capacity generated from wave energy, with inference results transmitted via satellite to land. The model combines hardware deployment with compute service delivery.
- Power Generation for Third Parties: Wave energy generation platform that could potentially supply power to maritime operations or coastal facilities, though primary focus is on-board AI compute usage.

Panthalassa product offering
Product offeringCore offering
Panthalassa builds autonomous, self-propelled floating wave energy nodes (the Ocean-3 series) that extract electricity from ocean wave motion through internal hydraulic systems and use that electricity to power onboard AI inference computing hardware. The sealed compute modules are cooled naturally by surrounding seawater, and inference results are transmitted to customers on land via Starlink satellite connectivity, enabling carbon-free AI compute that operates independently without anchors, fuel, or land tethers.
Product overview
Panthalassa is a public-benefit corporation building a planetary-scale wave energy platform for clean power generation and offshore AI computing. The company operates a two-product portfolio: Ocean-2 (the Pacific Ocean pilot deployment prototype, a 70-meter steel structure testing wave-to-compute technology off the Washington coast since 2025) and Ocean-3 (the commercial-ready autonomous floating node series that generates electricity from wave motion and performs AI inference computing directly at sea). Both products use seawater for natural cooling and satellite connectivity (Starlink) for data transmission, eliminating the need for land tethers, anchors, or grid connections. The platform is designed to address AI data center constraints including power availability, cooling water shortages, and permitting delays.
