Sources: 2. Developments: 2. A group of Silicon Valley investors, led by entrepreneur Martín Varsavsky, has purchased the 32,000-hectare Wamani ranch in Mendoza, Argentina. The project is designed as a self-sufficient enclave to serve as “apocalypse insurance” for the ultra-wealthy, providing protection against potential global catastrophes such as nuclear war, pandemics, or climate collapse. To achieve autonomy, the estate is being equipped with prefabricated housing, geodesic domes, a solar-powered runway, satellite communications, and solar-powered large language-model computers. The development has faced scrutiny from local groups, specifically the Asamblea Popular por el Agua. This organization has raised concerns regarding the estate's location at the headwaters of the Hondo and La Faja streams, warning that water diversion could impact the Diamante River basin and the downstream San Rafael oasis. While local organizations have questioned the use of these resources, official provincial assessments regarding water extraction have not been released. ## Timeline ### 2026-08-15: Martín Varsavsky develops Wamani billionaire refuge in Mendoza Businessman Martín Varsavsky is developing Wamani, a 32,000-hectare anti-nuclear refuge in Mendoza, Argentina, amid local concerns regarding its impact on regional water resources. 2 sources. https://clstr.news/cluster/martn-varsavsky-develops-wamani-billionaire-refuge-in-mendoza ### 2026-08-07: Martín Varsavsky's Argentine Ranch Targets Tech Billionaires' Bunker Tech investors led by Martín Varsavsky are building a self‑sufficient Argentine ranch as an apocalypse bunker for billionaires, spending $10 million on solar‑powered facilities and livestock. 2 sources. https://clstr.news/cluster/martn-varsavskys-argentine-ranch-targets-tech-billionaires-bunker --- Cite as: Wamani billionaire refuge development in Argentina.
