Fresh Hardt Hyperloop funding has revived the Rotterdam-based transit developer following insolvency proceedings earlier this year, securing millions of euros to finance an expansion into the Americas. The capital injection was led by Green Rock, an American investment and infrastructure development company, alongside several of the mobility firm’s existing shareholders.
Key points
- Dutch mobility developer Hardt Hyperloop raised a multi-million-euro round led by US infrastructure investor Green Rock.
- The funding marks a recovery after one of the startup’s corporate entities entered bankruptcy proceedings earlier in 2026.
- Existing investors and shareholders joined the round to support commercial and technical expansion into North and South America.
Capital rescue follows European insolvency
Hardt Hyperloop confirmed the multi-million-euro transaction after a turbulent period that saw one of its primary operating entities enter court-supervised bankruptcy proceedings earlier in the year. The fresh funding package stabilises the business and provides capital to continue developing its high-speed tube transit systems.
Lead investor Green Rock concentrates on strategic infrastructure projects and industrial technology deployments in the United States and international markets. Existing backers joined Green Rock in the consortium, reinvesting to protect their equity and preserve the intellectual property built in the Netherlands.
Targeting transit corridors across the Americas
The Dutch developer intends to use the capital to establish operational footholds across North and South America. Hyperloop technology aims to move passenger pods and freight through low-pressure tubes at airline speeds using electric propulsion and magnetic levitation, but commercial projects require long-term backing from regional infrastructure funds.
While earlier development work focused heavily on European test tracks and regional corridors, regulatory approvals and public procurement cycles on the continent have proved slow. Green Rock’s involvement gives the company direct access to American project developers who specialise in capital-intensive transport assets.
How hyperloop developers navigate infrastructure risk
Transport technology startups face high capital requirements before reaching revenue service. Similar challenges affect autonomous transit networks, where companies such as Alphabet have poured billions into regional testing, as seen when Waymo expanded robotaxi coverage across five US metros.
By securing transatlantic backing, Hardt Hyperloop aims to demonstrate that vacuum-tube transport remains viable despite industry-wide bankruptcies and project cancellations over recent years. The company has not yet disclosed the exact valuation or the detailed timeline for its upcoming American deployments.
