Google has secured a 14% stake in TeraWulf, a U.S.-based Bitcoin mining and data center operator, investing $3.2 billion in the company to support its shift towards artificial intelligence (AI) infrastructure. This strategic move highlights a growing trend of tech giants investing in AI-centric infrastructure leveraging sustainable energy from cryptocurrency miners. 2024’s Bitcoin halving led TeraWulf to diversify into AI and HPC hosting, a decision which has been further bolstered by Google’s investment. 2026 will see the launch of CB-5, a 160 MW facility for TeraWulf, part of a $6.7 billion revenue agreement with Fluidstack, an AI cloud platform. The partnership underscores a broader industry trend, where tech giants are exploring how to capitalize on the increasing demand for high-performance computing (HPC) infrastructure.
