Nscale, a data center developer backed by NVIDIA, is in talks with AI company Anthropic for a cloud computing deal worth approximately $45 billion, involving the second building at its Monarch data center campus in West Virginia, Bloomberg reported, citing sources. This potential transaction would significantly bolster Nscale's plans for an IPO seeking a valuation of around $30 billion. The building is reportedly set to feature NVIDIA's latest generation Vera Rubin AI chips. Anthropic and Nscale had previously signed an agreement for existing infrastructure valued at up to approximately $44.6 billion. Nscale confidentially filed for a U.S. listing in September and completed $3.36 billion in pre-IPO financing last month.
